Abstract
Abstract A battery charger that allows insertion of a battery for charging. When the battery is inserted it mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charger. The mechanical engagement of the battery with the activation mechanism causes at least one vent in the energy source to open. The energy source generates power when the at least one activating gas infiltrates into the energy source through the at least one open vent. The power generated by the energy source is coupled to the battery for charging.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
99 words
A method for charging a battery comprising the steps of: (a) inserting the battery in a charging device wherein the battery mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charging device; (b) opening at least one vent in the energy source in response to the mechanical engagement of the battery with the activation mechanism, the at least one open vent allowing infiltration of at least one activating gas into the energy source resulting in generation of electrical power thereby; and (c) charging the battery using electrical power generated by the energy source.
Claim 2
Independent Claim
99 words
A method for charging a battery comprising the steps of: (a) inserting the battery in a charging device wherein the battery mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charging device; (b) opening at least one vent in the energy source in response to the mechanical engagement of the battery with the activation mechanism, the at least one open vent allowing infiltration of at least one activating gas into the energy source resulting in generation of electrical power thereby; and (c) charging the battery using electrical power generated by the energy source.
Claim 3
Dependent Claim
19 words
The method of claim 1, which includes the step of (d) monitoring the battery to control the charging thereof.
Claim 4
Dependent Claim
60 words
The method according to claim 1, which includes the step of: (d) deactivating the energy source by closing the at least one vent in the energy source in response to mechanical disengagement of the battery from the activation mechanism, the at least one closed vent acting to impede infiltration of the at least one activating gas into the energy source.
Claim 5
Independent Claim
110 words
A method for charging a battery within an electronic device, comprising the steps of: (a) inserting the electronic device in a battery charging device wherein the battery mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charging device; (b) opening at least one vent in the energy source in response to the mechanical engagement of the electronic device with the activation mechanism, the at least one open vent allowing filtration of at least one activating gas into the energy source resulting in generation of electrical power thereby; and (c) charging the battery within the electronic device using electrical power generated by the energy source.
Claim 6
Independent Claim
110 words
A method for charging a battery within an electronic device, comprising the steps of: (a) inserting the electronic device in a battery charging device wherein the battery mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charging device; (b) opening at least one vent in the energy source in response to the mechanical engagement of the electronic device with the activation mechanism, the at least one open vent allowing filtration of at least one activating gas into the energy source resulting in generation of electrical power thereby; and (c) charging the battery within the electronic device using electrical power generated by the energy source.
Claim 7
Dependent Claim
19 words
The method of claim 4, which includes the step of (d) monitoring the battery to control the charging thereof.
Claim 8
Dependent Claim
61 words
The method according to claim 4, which includes the step of: (d) deactivating the energy source by closing the at least one vent in the energy source in response to mechanical disengagement of the electronic device from the activation mechanism, the at least one closed vent acting to impede infiltration of the at least one activating gas into the energy source.
Claim 9
Dependent Claim
25 words
The method of claim 4, which includes the step of: (d) operating the electronic device while the battery within the electronic device is being charged.
Claim 10
Dependent Claim
75 words
A battery charger, comprising: receiving means for receiving a battery and electrically coupling the battery to an energy source incorporated with the battery charger; and activating means that opens at least one vent in the energy source in response to the battery mechanically engaging the activating means, the at least one open vent allowing infiltration of at least one activating gas into the energy source resulting in generation of electrical power that charges the battery.
Claim 11
Dependent Claim
75 words
A battery charger, comprising: receiving means for receiving a battery and electrically coupling the battery to an energy source incorporated with the battery charger; and activating means that opens at least one vent in the energy source in response to the battery mechanically engaging the activating means, the at least one open vent allowing infiltration of at least one activating gas into the energy source resulting in generation of electrical power that charges the battery.
Claim 12
Dependent Claim
17 words
The battery charger of claim 8, which includes control means for controlling the charging of the battery.
Claim 13
Dependent Claim
36 words
