Abstract
Abstract An electrical power management system for supplying power to a computer peripheral having a relatively high intermittent power demand, such as a packet-switched data radio. A first self-contained rechargeable power supply, outputting power appropriate for the electrical appliance, stores electrical energy and supplies power to the appliance. A second self-contained rechargeable power supply stores electrical energy and supplies electrical power to intermittently recharge the first power supply. The first and the second power supplies can be such self-contained units as single or multicell batteries or capacitors. Preferably, the first power supply is a battery or a capacitor and the second power source is an internal power supply of a portable personal computer.

Claim 1
Independent Claim
135 words
An electrical power management element comprising: radio transmitter means for transmitting data; first power supply means, rechargeable, for storing electrical energy and supplying power to the radio transmitter means; second power supply means, self-contained, for storing electrical energy and supplying energy to recharge the first power supply means; means for switching electrical current output from the second power supply means to the first power supply means so as to recharge the first power supply means; means for controlling the recharging of the first power supply means by performing a set of programmed steps comprising: detecting the transmission data by the radio transmitter means; and activating the switch means to switch a predetermined quantity of energy output from the second power supply means to the first power supply means to charge the first power supply means.
Claim 2
Dependent Claim
135 words
An electrical power management element comprising: radio transmitter means for transmitting data; first power supply means, rechargeable, for storing electrical energy and supplying power to the radio transmitter means; second power supply means, self-contained, for storing electrical energy and supplying energy to recharge the first power supply means; means for switching electrical current output from the second power supply means to the first power supply means so as to recharge the first power supply means; means for controlling the recharging of the first power supply means by performing a set of programmed steps comprising: detecting the transmission data by the radio transmitter means; and activating the switch means to switch a predetermined quantity of energy output from the second power supply means to the first power supply means to charge the first power supply means.
Claim 3
Dependent Claim
151 words
An electrical power management element comprising: radio transmitter means for transmitting data; first power supply means for storing electrical energy and supply power to the radio transmitter means; second power supply means, self-contained for storing electrical energy and supplying electrical current to charge the first power supply means; means for switching electrical current output from the second power supply means to the first power supply means; means for controlling the energy to the first power supply means by performing a set of programmed steps comprising: detecting the transmission of data by the radio transmitter means; and activating the switch means to switch power output from the second power supply means to the first power supply means to charge the first power supply means, to thereby preserve the energy in the second power supply means by replacing some of the energy used by the first power supply means during the previous transmission.
Claim 4
Dependent Claim
151 words
An electrical power management element comprising: radio transmitter means for transmitting data; first power supply means for storing electrical energy and supply power to the radio transmitter means; second power supply means, self-contained for storing electrical energy and supplying electrical current to charge the first power supply means; means for switching electrical current output from the second power supply means to the first power supply means; means for controlling the energy to the first power supply means by performing a set of programmed steps comprising: detecting the transmission of data by the radio transmitter means; and activating the switch means to switch power output from the second power supply means to the first power supply means to charge the first power supply means, to thereby preserve the energy in the second power supply means by replacing some of the energy used by the first power supply means during the previous transmission.
