Abstract

A method of graduated residual battery power utilization of a long-life battery in a battery-powered device, comprising the steps of: defining at least one residual power level for the battery;assigning progressively limited battery-powered device functionalities for each of the at least one power level; and enabling the battery-powered device to be operated according to the at least one residual power level and the respective limited functionalities so as to extend the life of the battery and to avoid a depleted battery condition.

Claims

1. A method of graduated residual battery power utilization of a long-life battery in a battery-powered device, comprising the steps of:

a. defining at least one residual power level for the battery;

b. assigning progressively limited battery-powered device functionalities for each of the at least one power level; and

c. enabling the battery-powered device to be operated according to the at least one residual power level and the respective limited functionalities

so as to extend the life of the battery and to avoid a depleted battery condition.

2. The method of claim 1, wherein the limited functionalities serve to signal the need to replenish battery power.

3. The method of claim 2, wherein to signal the need to replenish battery power includes at least one chosen from the list including:

an electromagnetic wavelength transmission to a remote device;

a wired signal transmission to a remote device;

a visible display on the battery-powered device; and

an audible sound from the battery-powered device.

4. The method of claim 2, wherein replenishing battery power is chosen from the list including:

replacing the battery; and

recharging the battery.

5. The method of claim 2, wherein the remote device is chosen from the list including:

a key fob;

a magnetic card;

an RFID device;

a “

smart card”

;

a remote relay device;

a remote relay station;

a transmitter, a receiver;

a transceiver, a mobile phone, a PDA, a CPU, a vehicle remote control, a vehicle alarm remote control, and a portable computer.

6. The method of claim 2, wherein residual power levels are determined when the battery has substantially a full charge.

7. The method of claim 6, wherein the at least one residual power level includes at least one chosen from the list including:

LB, LBM, and LBC;

wherein LB is higher than LBM and LBM is higher than LBC.

8. The method of claim 6, wherein the battery-powered device is a door lock.

9. The method of claim 6, wherein the battery-powered device is a safe lock.

10. The method of claim 8, wherein functionality of the door lock includes at least one chosen from the list including:

a lock opening;

a lock closing;

a lock engaging; and

a transmission of lock status.

11. The method of claim 10, wherein the functionality of the door lock is progressively limited according to progressively lower residual power levels.

12. The method of claim 1, wherein the battery includes at least one chosen from the list including:

a rechargeable battery;

a non-rechargeable battery;

a combination rechargeable/non-rechargeable battery.

13. The method of claim 12, wherein the battery further includes at least one chosen from the list including at least one conventional alkaline battery;

at least one lithium ion battery;
