Claims
- 1. 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.
- 2. 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.
- 3. 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 recharge 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 recharging of the first power supply means by performing a set of programmed steps comprising:
- detecting the transmission of data by the radio transmitter means;
- quantifying the amount of energy utilized in the transmission of that data;
- adding the quantified amount of energy from the last transmission to previous transmissions occurring after the last recharge; and
- activating the switch means to switch power output from the second power supply means to the first power supply means to recharge the first power supply means, to thereby reserve the energy in the second power supply means by substantially replacing the energy used by the first power supply means during the previous transmissions.
- 4. An electrical power management system 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 electrical current 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;
- processor means for controlling the recharging of the first power supply means by performing a set of programmed steps comprising:
- detecting the transmission of data by radio transmitter means;
- deriving the amount of electrical energy consumed by the radio transmitter means during transmission of the data;
- computing a recharging time and power equal to the time and power required for the second power supply means to recharge the first power supply means so as to restore electrical energy to the first power supply means in an amount equal to the amount of electrical energy consumed by the radio transmitter means during transmission of the data;
- activating the switch means to switch power output from the second power supply means to the first power supply means to restore said electrical energy;
- reducing the amount of electrical energy being transferred to a trickle charge after restoration of said computed recharge power; and
- program memory means for storing machine-readable instructions utilized by said processor means to carry out said set of programmed steps.
