Abstract

An electronic lock for leveraging always-on lock indicator display technologies according to an embodiment includes a bistable display, at least one processor, and at least one memory comprising a plurality of instructions that, in response to execution by the at least one processor, causes the electronic lock to perform a diagnostic on the electronic lock to determine a status of the electronic lock, determine whether an error has occurred on the electronic lock based on the determined status of the electronic lock, and modify a current display image of the bistable display to display an error code on the bistable display in response to a determination that the error has occurred on the electronic lock, wherein the error code is associated with the error that has occurred on the electronic lock.

Claims (33)

1 . An electronic lock for leveraging always-on lock indicator display technologies, the electronic lock comprising:

a bistable display;

at least one processor; and

at least one memory comprising a plurality of instructions that, in response to execution by the at least one processor, causes the electronic lock to:

perform a diagnostic on the electronic lock to determine a status of the electronic lock;

determine whether an error has occurred on the electronic lock based on the determined status of the electronic lock;

modify a current display image of the bistable display to display an error code on the bistable display in response to a determination that the error has occurred on the electronic lock, wherein the error code is associated with the error that has occurred on the electronic lock;

determine a lock status of the electronic lock in response to a determination that an error has not occurred on the electronic lock;

modify the current display image of the bistable display to display a locked status indicator in response to a determination that the electronic lock is locked; and

modify the current display image of the bistable display to display an unlocked status indicator in response to a determination that the electronic lock is unlocked.

2 . The electronic lock of claim 1 , wherein the bistable display comprises an electrophoretic display.

3 . The electronic lock of claim 1 , wherein the bistable display comprises a bistable liquid crystal display.

4 . The electronic lock of claim 1 , wherein the bistable display comprises an electrochromic display.

5 . The electronic lock of claim 1 , wherein to perform the diagnostic on the electronic lock comprises to generate audit data for the electronic lock.

6 . The electronic lock of claim 1 , wherein to display the error code on the bistable display in response to the determination that the error has occurred on the electronic lock comprises to display a quick response (QR) code on the bistable display.

7 . The electronic lock of claim 1 , wherein to display the error code on the bistable display in response to the determination that the error has occurred on the electronic lock comprises to display a bar code on the bistable display.

8 . The electronic lock of claim 1 , wherein to modify the current display image of the bistable display comprises to display a link to a website associated with error handling for the error associated with the error code.

9 . The electronic lock of claim 1 , wherein the plurality of instructions further causes the electronic lock to modify the current display image of the bistable display to display a link to a website associated with installation instructions in response to a determination that the electronic lock is in an installation phase of device onboarding.

10 . The electronic lock of claim 1 , wherein the plurality of instructions further causes the electronic lock to modify the current display image of the bistable display to display a code associated with commissioning details for the electronic lock in response to a determination that the electronic lock is in a commissioning phase of device onboarding.

11 . The electronic lock of claim 1 , wherein to perform the diagnostic on the electronic lock comprises to perform the diagnostic on the electronic lock at boot up of the electronic lock.

12 . A method for leveraging always-on lock indicator display technologies, the method comprising:

performing, by an electronic lock, a diagnostic on the electronic lock to determine a status of the electronic lock;

determining, by the electronic lock, whether an error has occurred on the electronic lock based on the determined status of the electronic lock;

modifying, by the electronic lock, a current display image of a bistable display of the electronic lock to display an error code on the bistable display in response to determining that the error has occurred on the electronic lock, wherein the error code is associated with the error that has occurred on the electronic lock;

determining, by the electronic lock, a lock status of the electronic lock in response to determining that an error has not occurred on the electronic lock;

modifying, by the electronic lock, the current display image of the bistable display to display a locked status indicator in response to determining that the electronic lock is locked; and

modifying, by the electronic lock, the current display image of the bistable display to display an unlocked status indicator in response to determining that the electronic lock is unlocked.

13 . The method of claim 12 , wherein the bistable display comprises one of an electrophoretic display, a bistable liquid crystal display, or an electrochromic display.

14 . The method of claim 12 , wherein performing the diagnostic on the electronic lock comprises generating audit data for the electronic lock.

15 . The method of claim 12 , wherein modifying the current display image of the bistable display to display the error code in response to determining that the error has occurred on the electronic lock comprises displaying one of a quick response (QR) code or a barcode on the bistable display.

16 . The method of claim 12 , wherein modifying the current display image of the bistable display comprises displaying a link to a website associated with error handling for the error associated with the error code.

17 . The method of claim 12 , further comprising modifying, by the electronic lock, the current display image of the bistable display to display a link to a website associated with installation instructions in response to determining that the electronic lock is in an installation phase of device onboarding.

18 . The method of claim 12 , further comprising modifying, by the electronic lock, the current display image of the bistable display to display a code associated with commissioning details for the electronic lock in response to determining that the electronic lock is in a commissioning phase of device onboarding.
