== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

The goal of this report is to:
* Summarize IP activity over the years
* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''And then'''

* Analyze patents pertaining to high sebum activity

== Approach ==

* A broad search was conducted on hair loss patents.
* Patent information was sourced through SIP.
* A set of patents was selected for analysis.

Composition of treatment for causes are identified and categorized as follows:

* Anti-androgen
* Minoxidil
* Double action (Anti-androgen + Mindoxidil)
* Hair matrix cells activator
* Sebum production inhibitor

== IP activity over years ==
The graph indicates:
* Number of patents filed every 5 years (except for first 7 years).
* First solution proposed in 1973
* Filing trend indicates steep rise in activity recently.
[[Image:Year1.jpg|thumb|center|400px|IP Activity over years]]

== Major Players ==
[[Image:players.jpg|thumb|left|400px|Assignees with more than 20 patents ]]
[[Image:players1.jpg|thumb|center|400px|Assignees with fewer than 20 patents ]]

* '''Active Assignees'''
Assignees currently active with more than 5 patents to their credit during 2000-2005.
* Warner with 9 patents,
* Bristol with 6 and
* Abbott with 5.

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Minoxidil ==
* A thick network of tiny veins and arteries lines the outer wall of the follicle. Blood pumps through the bulb and hair via this network
* Minoxidil dilates blood vessels; which is also called as “potassium channel opener”
* Minoxidil sulfate (MS) appears to be the active metabolite responsible for hair growth stimulation.

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

[[Image:coloury.jpg]]- '''Target sites and Details'''

== Pyrazole compounds ==

* '''Pyrazole''' (C3H4N2) refers both to the class of simple aromatic ring organic compounds of the heterocyclic series characterized by a 5-membered ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions and to the unsubstituted parent compound. Being so composed and having pharmacological effects on humans, they are classified as alkaloids although they are not known to occur in nature.
* Pyrazoles are produced synthetically through the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation
[[Image:pyrazole1.jpg|thumb|center|500px|Pyrazole (C3H4N2)]]
* Pyrazoles are used for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities.
* Structurally related compounds are pyrazoline and pyrazolidine.

== Summary ==

Alopecia - Hair Loss

2006-05-09T17:59:26Z

Aziz:

== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Alopecia IPMap ==
[http://www.dolcera.com/client/ds94x0s90akq9d7xb402fm/hairloss_map.htm Dolcera IPMap for Alopecia]

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

The goal of this report is to:
* Summarize IP activity over the years
* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''And then'''

* Analyze patents pertaining to high sebum activity

== Approach ==

* A broad search was conducted on hair loss patents.
* Patent information was sourced through SIP.
* A set of patents was selected for analysis.

Composition of treatment for causes are identified and categorized as follows:

* Anti-androgen
* Minoxidil
* Double action (Anti-androgen + Mindoxidil)
* Hair matrix cells activator
* Sebum production inhibitor

== IP activity over years ==
The graph indicates:
* Number of patents filed every 5 years (except for first 7 years).
* First solution proposed in 1973
* Filing trend indicates steep rise in activity recently.
[[Image:Year1.jpg|thumb|center|400px|IP Activity over years]]

== Major Players ==
[[Image:players.jpg|thumb|left|400px|Assignees with more than 20 patents ]]
[[Image:players1.jpg|thumb|center|400px|Assignees with fewer than 20 patents ]]

* '''Active Assignees'''
Assignees currently active with more than 5 patents to their credit during 2000-2005.
* Warner with 9 patents,
* Bristol with 6 and
* Abbott with 5.

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Minoxidil ==
* A thick network of tiny veins and arteries lines the outer wall of the follicle. Blood pumps through the bulb and hair via this network
* Minoxidil dilates blood vessels; which is also called as “potassium channel opener”
* Minoxidil sulfate (MS) appears to be the active metabolite responsible for hair growth stimulation.

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

== Sebum Production Inhibitor ==
* Sebum, a complex mixture of lipid substances, is secreted from sebaceous glands associated with hair follicles.
* The inhibitor blocks the excessive sebum production produces greasy effect on hair and scalp and also responsible for thinning and loosing of hair.

== Pyrazole compounds ==

* '''Pyrazole''' (C3H4N2) refers both to the class of simple aromatic ring organic compounds of the heterocyclic series characterized by a 5-membered ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions and to the unsubstituted parent compound. Being so composed and having pharmacological effects on humans, they are classified as alkaloids although they are not known to occur in nature.
* Pyrazoles are produced synthetically through the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation
[[Image:pyrazole1.jpg|thumb|center|500px|Pyrazole (C3H4N2)]]
* Pyrazoles are used for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities.
* Structurally related compounds are pyrazoline and pyrazolidine.

* Are there any loopholes in their patents?
* When are their patents expiring?
* Will a competitor emerge from nowhere and surprise me?
* What are the crowded areas?

'''How do I play defense?'''
* What should my blocking/reactive strategies be?

== New Combinations based on IP study? ==

Yes, new Combinations can be made with '''natural products''' based on IP study
* Walnut extract containing [[Image:5ar.jpg]] inhibitor (as anti-androgen) and Flavnones (for vasodilation).
* Sophora Flavnones (for vasodilation) in combination with Saw Palmetto berry (as anti-androgen).

'''Note:''' The above combinations are based on limited study and are only possible examples

== IP studies provides ==

=== Technology trends ===
* Use of saw palmetto berry for treating alopecia was first patented in 1996.
* Since then, 144 patents (including family patents) have been filed till 2006.
* Most patents use saw palmetto berry in combination with other products.
[[Image:Technology1.jpg|thumb|center|700px|Technology trends]]

=== New opportunities ===
Yes, the IP studies provide new opportunities in the following area.
* Sophora Flavescens contain flavnoids.
* Natural extract Sophora Flavescens cited in LG patent of 2001.
* Research shows fewer than 7 patents based on Sophora Flavescens for hair loss or alopecia.

== Conclusions ==
* Hair loss medication is a very active area of research and intellectual property development.
* One of the most promising areas of development is the area of Anti-androgens.
* The top companies are Merck, L’Oreal and Smithkline.

== Summary ==

Alopecia - Hair Loss

2006-05-09T17:57:13Z

Aziz:

== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Alopecia IPMap ==

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

The goal of this report is to:
* Summarize IP activity over the years
* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''And then'''

* Analyze patents pertaining to high sebum activity

== Approach ==

* A broad search was conducted on hair loss patents.
* Patent information was sourced through SIP.
* A set of patents was selected for analysis.

Composition of treatment for causes are identified and categorized as follows:

* Anti-androgen
* Minoxidil
* Double action (Anti-androgen + Mindoxidil)
* Hair matrix cells activator
* Sebum production inhibitor

== IP activity over years ==
The graph indicates:
* Number of patents filed every 5 years (except for first 7 years).
* First solution proposed in 1973
* Filing trend indicates steep rise in activity recently.
[[Image:Year1.jpg|thumb|center|400px|IP Activity over years]]

== Major Players ==
[[Image:players.jpg|thumb|left|400px|Assignees with more than 20 patents ]]
[[Image:players1.jpg|thumb|center|400px|Assignees with fewer than 20 patents ]]

* '''Active Assignees'''
Assignees currently active with more than 5 patents to their credit during 2000-2005.
* Warner with 9 patents,
* Bristol with 6 and
* Abbott with 5.

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Minoxidil ==
* A thick network of tiny veins and arteries lines the outer wall of the follicle. Blood pumps through the bulb and hair via this network
* Minoxidil dilates blood vessels; which is also called as “potassium channel opener”
* Minoxidil sulfate (MS) appears to be the active metabolite responsible for hair growth stimulation.

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

[[Image:coloury.jpg]]- '''Target sites and Details'''

== Pyrazole compounds ==

* '''Pyrazole''' (C3H4N2) refers both to the class of simple aromatic ring organic compounds of the heterocyclic series characterized by a 5-membered ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions and to the unsubstituted parent compound. Being so composed and having pharmacological effects on humans, they are classified as alkaloids although they are not known to occur in nature.
* Pyrazoles are produced synthetically through the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation
[[Image:pyrazole1.jpg|thumb|center|500px|Pyrazole (C3H4N2)]]
* Pyrazoles are used for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities.
* Structurally related compounds are pyrazoline and pyrazolidine.

== Summary ==

Alopecia - Hair Loss

2006-05-09T17:56:21Z

Aziz:

== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Alopecia IPMap ==
[http://www.dolcera.com/client/ds94x0s90akq9d7xb402fm/hairloss_map.htm Dolcera IPMap for Alopecia]

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

The goal of this report is to:
* Summarize IP activity over the years
* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''And then'''

* Analyze patents pertaining to high sebum activity

== Approach ==

* A broad search was conducted on hair loss patents.
* Patent information was sourced through SIP.
* A set of patents was selected for analysis.

Composition of treatment for causes are identified and categorized as follows:

* Anti-androgen
* Minoxidil
* Double action (Anti-androgen + Mindoxidil)
* Hair matrix cells activator
* Sebum production inhibitor

== IP activity over years ==
The graph indicates:
* Number of patents filed every 5 years (except for first 7 years).
* First solution proposed in 1973
* Filing trend indicates steep rise in activity recently.
[[Image:Year1.jpg|thumb|center|400px|IP Activity over years]]

== Major Players ==
[[Image:players.jpg|thumb|left|400px|Assignees with more than 20 patents ]]
[[Image:players1.jpg|thumb|center|400px|Assignees with fewer than 20 patents ]]

* '''Active Assignees'''
Assignees currently active with more than 5 patents to their credit during 2000-2005.
* Warner with 9 patents,
* Bristol with 6 and
* Abbott with 5.

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Minoxidil ==
* A thick network of tiny veins and arteries lines the outer wall of the follicle. Blood pumps through the bulb and hair via this network
* Minoxidil dilates blood vessels; which is also called as “potassium channel opener”
* Minoxidil sulfate (MS) appears to be the active metabolite responsible for hair growth stimulation.

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

== Sebum Production Inhibitor ==
* Sebum, a complex mixture of lipid substances, is secreted from sebaceous glands associated with hair follicles.
* The inhibitor blocks the excessive sebum production produces greasy effect on hair and scalp and also responsible for thinning and loosing of hair.

[[Image:coloury.jpg]]- '''Target sites and Details'''

== Pyrazole compounds ==

* '''Pyrazole''' (C3H4N2) refers both to the class of simple aromatic ring organic compounds of the heterocyclic series characterized by a 5-membered ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions and to the unsubstituted parent compound. Being so composed and having pharmacological effects on humans, they are classified as alkaloids although they are not known to occur in nature.
* Pyrazoles are produced synthetically through the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation
[[Image:pyrazole1.jpg|thumb|center|500px|Pyrazole (C3H4N2)]]
* Pyrazoles are used for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities.
* Structurally related compounds are pyrazoline and pyrazolidine.

Hybrid Electric Vehicle Battery System

2006-04-29T06:18:17Z

== Rationale ==
[[image:globalwarming.jpg|thumb|right|220px|Global warming emissions by sector]]

* Automobiles are a source of considerable pollution at the global level, including a significant fraction of the total greenhouse gas emissions.
* On July 22, 2002 California Governor Gray Davis signed into law AB 1493 (commonly known as the "Pavley law") — precedent-setting legislation to reduce global warming pollution from motor vehicles.
* This bill directs the California Air Resources Board (CARB) to develop and adopt regulations that achieve the maximum feasible and cost-effective reduction of greenhouse gas emissions (GHG) from passenger cars and light trucks sold in California.

== New Developments ==
The new millennium is bringing a millennial change to the family car. A few years back, the key concerns were:
* Pollution,
* Nagging worries about global warming, and
* Oil shortages.
These concerns led to the development of Electric Vehicle (EV’s) powered by batteries. But current battery technology does not provide EV's with a range that is acceptable to consumers.

'''Limitations of EV’s''':
* An average commute to work is around 40 miles.
* EV's have a range of 80-100 miles using advanced battery technology.
* While batteries need frequent recharging, they are not the only way to power an electric car.

== Hybrid Electric Vehicle (HEV) ==
The Hybrid Electric Vehicle (HEV) is just the first step in reducing the environmental impacts of automobile use without losing comfort, performance, storage room and extended driving range.

'''Advantages of HEV’s''':
* The HEV contains parts of both gasoline and electric vehicles in an attempt to get the best of both worlds.
* It is able to operate nearly twice as efficiently as traditional internal combustion vehicles.
* It has equivalent power, range, cost and safety of a conventional vehicle while reducing fuel costs and harmful emissions.
* The battery is continuously recharged by a motor/generator driven by the Internal Combustion Engine (ICE) or by regenerative braking.

== Components of the HEV Battery System ==
The battery in an HEV is the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor in a hybrid car can put energy into the battery as well as draw energy from it.

* '''Battery''': Two or more electrochemical energy cells connected together to provide electrical energy.
* '''Generator''': The generator is similar to an electric motor, but it acts only to produce electrical power.
* '''Electric motor''': Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries.
* '''SOC''': The State of Charge of a battery is its available capacity expressed as a percentage of its rated capacity

[[Image:Hev layout.jpg|thumb|center|700px|Components of the HEV Battery System]]

== HEV battery system design parameters ==

Factors affecting battery performance:
* Temperature: Battery performance is highly dependent on temperature. Each type of battery works best within a limited range of temperatures.
* Battery age/Shelf life: Corrosion is the main culprit behind decreased performance in lead acid type batteries with age.
* Depth of discharge: Batteries are able to maintain their performance longer when they are not deeply discharged regularly.

Design parameters:
* How much space is available for the batteries?
* How much can they weigh?
* What is the desired range?
* What is the weight of the vehicle?
* What is the targeted vehicle cost?
* How will the batteries be recharged and
* What kind of drive system requirements is needed?

These questions are necessary because of the variety of battery types available and the differences between them. The chart below lists the characteristics of the most common types of batteries. (Source [http://www.atti-info.org/technology/ev_tech.html])

[[Image:batterytypes.jpg|thumb|center|400px|Battery types by descending order of popularity]]

== Comparison of top 3 batteries used in HEVs ==
During recharging, it is important to maintain the balance of battery. The balance of battery is maintained by controlling battery from overcharging and over discharging.

The battery is controlled by defining State of Charge (SOC) of the battery:
* Upper limit value – overcharge and
* Lower limit value – over discharge

When overcharge is detected, power generation is controlled/cut-off and when over discharge is detected, power supply to electric motor is stopped. Detection is achieved by appropriate sensors.
'''''This report investigates various procedures available/adopted by various assignees in order to maintain balanced battery pack by avoiding overcharge and/or over discharge.

</blockquote>

== HEV battery system concerns ==
The ultimate goal of HEV can only be achieved with the balance battery pack since the main source of energy is batteries and recharging is carried out on board.

'''Advantages of balance battery pack''':
* Balancing of battery SOC’s increases battery life
* Automated balancing circuitry will decrease overcharging (and gassing) and decrease manual maintenance.

This, in turn, provides:
* Equivalent power range at low cost as conventional vehicle while reducing fuel costs and harmful emissions.
* Twice the travel distance of a conventional vehicle on the same amount of energy.

== Rationale ==
[[image:globalwarming.jpg|thumb|right|220px|Global warming emissions by sector]]

* Automobiles are a source of considerable pollution at the global level, including a significant fraction of the total greenhouse gas emissions.
* On July 22, 2002 California Governor Gray Davis signed into law AB 1493 (commonly known as the "Pavley law") — precedent-setting legislation to reduce global warming pollution from motor vehicles.
* This bill directs the California Air Resources Board (CARB) to develop and adopt regulations that achieve the maximum feasible and cost-effective reduction of greenhouse gas emissions (GHG) from passenger cars and light trucks sold in California.

== New Developments ==
The new millennium is bringing a millennial change to the family car. A few years back, the key concerns were:
* Pollution,
* Nagging worries about global warming, and
* Oil shortages.
These concerns led to the development of Electric Vehicle (EV’s) powered by batteries. But current battery technology does not provide EV's with a range that is acceptable to consumers.

'''Limitations of EV’s''':
* An average commute to work is around 40 miles.
* EV's have a range of 80-100 miles using advanced battery technology.
* While batteries need frequent recharging, they are not the only way to power an electric car.

== Hybrid Electric Vehicle (HEV) ==
The Hybrid Electric Vehicle (HEV) is just the first step in reducing the environmental impacts of automobile use without losing comfort, performance, storage room and extended driving range.

'''Advantages of HEV’s''':
* The HEV contains parts of both gasoline and electric vehicles in an attempt to get the best of both worlds.
* It is able to operate nearly twice as efficiently as traditional internal combustion vehicles.
* It has equivalent power, range, cost and safety of a conventional vehicle while reducing fuel costs and harmful emissions.
* The battery is continuously recharged by a motor/generator driven by the Internal Combustion Engine (ICE) or by regenerative braking.

== Components of the HEV Battery System ==
The battery in an HEV is the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor in a hybrid car can put energy into the battery as well as draw energy from it.

* '''Battery''': Two or more electrochemical energy cells connected together to provide electrical energy.
* '''Generator''': The generator is similar to an electric motor, but it acts only to produce electrical power.
* '''Electric motor''': Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries.
* '''SOC''': The State of Charge of a battery is its available capacity expressed as a percentage of its rated capacity

[[Image:Hev layout.jpg|thumb|center|500px|Components of the HEV Battery System]]

== HEV battery system design parameters ==

Factors affecting battery performance:
* Temperature: Battery performance is highly dependent on temperature. Each type of battery works best within a limited range of temperatures.
* Battery age/Shelf life: Corrosion is the main culprit behind decreased performance in lead acid type batteries with age.
* Depth of discharge: Batteries are able to maintain their performance longer when they are not deeply discharged regularly.

Design parameters:
* How much space is available for the batteries?
* How much can they weigh?
* What is the desired range?
* What is the weight of the vehicle?
* What is the targeted vehicle cost?
* How will the batteries be recharged and
* What kind of drive system requirements is needed?

These questions are necessary because of the variety of battery types available and the differences between them. The chart below lists the characteristics of the most common types of batteries. (Source [http://www.atti-info.org/technology/ev_tech.html])

[[Image:batterytypes.jpg|thumb|center|400px|Battery types by descending order of popularity]]

== Comparison of top 3 batteries used in HEVs ==
During recharging, it is important to maintain the balance of battery. The balance of battery is maintained by controlling battery from overcharging and over discharging.

The battery is controlled by defining State of Charge (SOC) of the battery:
* Upper limit value – overcharge and
* Lower limit value – over discharge

When overcharge is detected, power generation is controlled/cut-off and when over discharge is detected, power supply to electric motor is stopped. Detection is achieved by appropriate sensors.
'''''This report investigates various procedures available/adopted by various assignees in order to maintain balanced battery pack by avoiding overcharge and/or over discharge.
'''''

</blockquote>

== HEV battery system concerns ==
The ultimate goal of HEV can only be achieved with the balance battery pack since the main source of energy is batteries and recharging is carried out on board.

'''Advantages of balance battery pack''':
* Balancing of battery SOC’s increases battery life
* Automated balancing circuitry will decrease overcharging (and gassing) and decrease manual maintenance.

This, in turn, provides:
* Equivalent power range at low cost as conventional vehicle while reducing fuel costs and harmful emissions.
* Twice the travel distance of a conventional vehicle on the same amount of energy.

Aziz:

== Rationale ==
* “Medication for men plagued by hair loss has become a topic of interest in Japan since a drug company began marketing it at the end of last year." March 5th, 2006 – [http://stophair.setupmyblog.com/?p=55]

* “An increasing number of companies are apparently turning the Chinese fear of a bald spot into big bucks with some doing so well they are branching out into other countries.” February 16, 2006 – [http://stophair.setupmyblog.com/]

== Introduction ==

=== Hair Basics ===
* Hair is a complex and delicate part of the body
* Keeping it healthy and beautiful is a challenge
* Structure of Hair root - [http://www.follicle.com/hair-structure-life-cycle.html]
* Structure of Hair bulb - [http://www.pg.com/science/haircare/hair_twh_12.htm]
[[Image:Hairbasics.jpg|thumb|center|500px|Structure of Hair root and Hair bulb]]

=== Reasons for Hair loss ===
[[Image:Facts.jpg|thumb|right|400px|Survey results from Japan]]
Both men and women lose hair for similar reasons. Hair loss in men is often more dramatic, and follows a specific pattern of loss which has been termed “Male Pattern Baldness” (Androgenetic Alopecia).

'''Main reasons'''
* Hormonal effect of androgen
* Reduction of blood circulation around hair follicle
* Deactivation of hair matrix cells

'''Some facts from Japan'''

* Market size: ¥ 30 Billion
* Number of products: more than 100

(JICST-EPlus - Japanese Science & Technology)

== Goals ==

* Identify major players
* Conduct patent analysis
a) Composition
b) Nature
c) Action

'''Alopecia occurs due to'''

* Hormonal effects of androgens
* Reduction of blood circulation around hair follicle

[[Image:Active.jpg|thumb|center|500px|Active Assignees]]

== Anti-androgens ==
* Anti-androgen is a substance that inhibits biological effects of androgenic hormones
* 5-alpha reductase + Testosterone = Dihydrotestosterone (DHT)
* DHT attaches to an Androgen Receptor.
* DHT causes increase in hair loss and gradual miniaturization of the follicle, which eventually dies resulting hair loss

== Hair matrix cell activator ==
* Stem cells of the hair follicle are gathered in the basal layer of the outer root sheath bulge.
* It is from these cells that matrix cells are formed.
* Growth and differentiation of the matrix cells are under the influence of substances produced by cells of the dermal papilla.

== New Combinations based on IP study? ==

Yes, new Combinations can be made with '''natural products''' based on IP study
* Walnut extract containing [[Image:5ar.jpg]] inhibitor (as anti-androgen) and Flavnones (for vasodilation).
* Sophora Flavnones (for vasodilation) in combination with Saw Palmetto berry (as anti-androgen).

'''Note:''' The above combinations are based on limited study and are only possible examples

== IP studies provides ==

=== Technology trends ===

=== New opportunities ===
Yes, the IP studies provide new opportunities in the following area.
* Sophora Flavescens contain flavnoids.
* Natural extract Sophora Flavescens cited in LG patent of 2001.
* Research shows fewer than 7 patents based on Sophora Flavescens for hair loss or alopecia.

== Conclusions ==
* Hair loss medication is a very active area of research and intellectual property development.
* One of the most promising areas of development is the area of Anti-androgens.
* The top companies are Merck, L’Oreal and Smithkline.
