Electronic lock having usage and wear leveling of a touch surface through randomized code entry

摘要

An electronic lock that requires the user complete a wear leveling action prior to entering in the passcode. The wear leveling action causes the user to touch one or more portions of the touch interface that may not be associated with the passcode to distribute wear of the touch interface. These area(s) of the touch interface selected for the wear leveling actions could be determined based on a pseudorandom number generator and/or by tracking usage of the touch interface to identify less used areas.

1. An electronic lock comprising:
a latch assembly including a bolt movable between an extended position and a retracted position; a touch interface; and a circuit in electrical communication with the touch interface, wherein the circuit is configured to control movement of the bolt from the extended position to the retracted position responsive to a valid passcode being entered into the touch interface; and wherein the circuit is configured to require a wear leveling action that requires selection of one or more portions of the touch interface by a user prior to entering a passcode, wherein the selection requires a user to touch and hold the one or more portions of the touch interface for a predetermined period of time and the predetermined period of time is longer than a time period needed to enter a passcode on the touch interface.
