Abstract

An exemplary embodiment pertains to a method of operating an electronic lockset during a plurality of iterations of a recurring period of time, wherein the electronic lockset includes a first electronic component. The method generally includes generating a usage score for the electronic component based on usage of the electronic lockset during the first iteration of the recurring period of time, selecting a schedule for the electronic component based on the first usage score, and during a second iteration of the recurring period of time occurring after the first iteration of the recurring period of time, operating the electronic component operating according to the selected schedule.

First claim

What is claimed is:

1. A method of operating a lockset during a plurality of iterations of a recurring period of time, wherein each iteration of the recurring period of time comprises a plurality of blocks, and wherein the lockset includes an electronic component, the method comprising:
adjusting a usage score of a first block of the plurality of blocks based on usage of the lockset during the first block in a first iteration of the recurring period of time;
for the first block, selecting a first block-specific schedule for the electronic component based on the usage score of the first block, wherein the selecting the first block-specific schedule comprises:
selecting the first block-specific schedule as a higher-power schedule in response to the usage score of the first block satisfying a first criterion; and
selecting the first block-specific schedule as a lower-power schedule in response to the usage score of the first block satisfying a second criterion different from the first criterion; and

during a second iteration of the recurring period of time, operating the electronic component during the first block according to the first block-specific schedule.

2. The method of claim 1 , further comprising:
adjusting a usage score of a second block of the plurality of blocks based on usage of the lockset during the second block in the first iteration of the recurring period of time;
for the second block, selecting a second block-specific schedule for the electronic component based on the usage score of the second block, the selecting comprising:
selecting the second block-specific schedule as the higher-power schedule in response to the usage score of the second block satisfying the first criterion; and
selecting the second block-specific schedule as the lower-power schedule in response to the usage score of the second block satisfying the second criterion; and

during the second iteration of the recurring period of time, operating the electronic component during the second block according to the second block-specific schedule.

3. The method of claim 1 , wherein the adjusting is performed by a controller of the lockset.

4. The method of claim 1 , wherein the selecting of the first block-specific schedule for the electronic component is performed by a controller of the lockset.

5. The method of claim 1 , further comprising adjusting the usage score for the first block based on usage of the lockset during the first block during the second iteration of the recurring period of time.

6. The method of claim 5 , further comprising:
updating the first block-specific schedule based on the usage score for the first block as adjusted for usage of the lockset during the first block during the second iteration of the recurring period of time; and
during a third iteration of the recurring period of time, operating the electronic component during the first block according to the updated first block-specific schedule.

7. The method of claim 1 , wherein the operating the electronic component during the first block according to the first block-specific schedule comprises deactivating the electronic component.

8. The method of claim 1 , wherein t selecting the first block-specific schedule further comprises selecting the first block-specific schedule as a no-power schedule in response to the usage score of the first block satisfying a third criterion different from the first criterion and the second criterion.

9. The method of claim 1 , wherein the selecting the first block-specific schedule further comprises selecting the first block-specific schedule as an override schedule in response to receiving an override signal from an external device.

10. The method of claim 1 , wherein the adjusting the usage score of the first block comprises decreasing the usage score of the first block in response to the lockset not being used during the first iteration of the first block;
wherein the usage score of the first block satisfies the first criterion when the usage score of the first block exceeds a predetermined threshold; and
wherein the usage score of the first block satisfies the second criterion when the usage score of the first block falls below the predetermined threshold.

11. A method of operating a lockset including an electronic component during a plurality of iterations of a recurring period of time, wherein each iteration of the recurring period of time includes a corresponding iteration of each block of a plurality of blocks, the method comprising:
adjusting a usage score of a first block of the plurality of blocks based on usage of the lockset during the first block in a first iteration of the recurring period of time;
selecting a schedule for the first block based on the usage score of the first block, wherein the selecting the schedule for the first block comprises:
selecting a first schedule for the first block in response to the usage score exceeding a predetermined usage score threshold; and
selecting a second schedule for the first block in response to the usage score falling below the predetermined usage score threshold; and

during a second iteration of the recurring period of time, operating the electronic component during the first block according to the schedule selected for the first block.

12. The method of claim 11 , wherein the first schedule is a higher-power schedule; and
wherein the second schedule is a lower-power schedule.

13. The method of claim 11 , further comprising, prior to adjusting the usage score of the first block, assigning the usage score to the first block.

14. The method of claim 13 , wherein the usage score assigned to the first block is based on an anticipated usage of the lockset during the first block.

15. The method of claim 11 , further comprising determining the usage of the lockset during the first block based on usage of the electronic component during the first block.

16. The method of claim 11 , further comprising determining the usage of the lockset during the first block based on information received from one or more sensors of the lockset.

17. The method of claim 11 , wherein the selecting the schedule for the first block further comprises selecting the first block-specific schedule as an override schedule in response to receiving an override signal from an external device.

18. A method, comprising:
operating a lockset during a first iteration of a recurring period of time, wherein the lockset comprises an electronic component, and wherein each iteration of the recurring period of time comprises a plurality of blocks;
determining usage of the lockset during each block of the first iteration of the recurring period of time;
adjusting a usage score for each block based on the usage of the lockset during the block in the first iteration of the recurring period of time;
selecting a schedule for a first block of the plurality of blocks based on the usage score of the first block, wherein selecting the schedule for the first block comprises:
selecting a first schedule for the first block in response to the usage score satisfying a first criterion; and
selecting a second schedule for the block in response to the usage score satisfying a second criterion different from the first criterion; and

during a second iteration of the recurring period of time, operating the electronic component according to the selected schedule during the first block.

19. The method of claim 18 , further comprising:
receiving an override signal from an external device, the override signal relating to a sec
