Abstract: An electronic lock includes a lock body and a shackle selectively securable via one or more ball bearings. An asymmetric cam can be rotated by a key or an electric motor to: a locked state in which the ball bearing secures the shackle within the lock body via at least one lock notch in the shackle, an unlocked state in which the ball bearing is released from the lock notch to unlock the shackle and subsequently engages a revolved notch on a distal end of the shackle to prevent removal of the shackle from the lock body, and a removal state in which the ball bearing is released from the lock notch and the revolved notch to allow the shackle to be removed from the lock body. A shackle detector can detect a shackle in the locked state. Externally accessible electrical contacts allow for jumpstarting a discharged battery.

Abstract: This disclosure provides systems and methods for lockout-tagout procedures and systems supporting the same, including, without limitation, lockout devices that can store and maintain digital locks simultaneously by multiple keyholders. In various embodiments, a single user can add multiple keyholders to a digital lock. The user may not be able to remove anyone as a keyholder except herself. Thus, the digital lock may remain in a locked state until each of the added keyholders applies their digital key, password, pin, and/or other personal identifying information to unlock the digital by removing themselves as a keyholder.

Abstract: In various embodiments, an electronic lock includes a locking mechanism to selectively transition between locked and unlocked states. A controller and capacitive touch sensor to detect and distinguish between short touch inputs having a touch duration less than a time threshold and long touch inputs having a touch duration greater than a time threshold. If the detected series or pattern of short and long touch interactions matches a stored series of touch interactions defining an unlock code, the locking mechanism transitions from the locked state to the unlocked state.

Abstract: An electronic locking device can be configured to become active from a low power state, receive physical input to unlock, and provide access to a replaceable power supply. An electronic locking device can use a combination of physical input and discovery of an authorized mobile device to enable transition from a locked state to an unlocked state. Authorization can be internally stored or externally obtained through a service. An electronic locking device can match a series of physical interactions to a series of stored interactions to enable transition from a locked state to an unlocked state, when an authorized device is unavailable. An electronic locking device can provide access to a replaceable power supply when a latch is released.

Abstract: Disclosed are electronic padlocks and related methods. An electronic padlock includes a lock body, a shank, and a locking mechanism operably coupled to electronic circuitry configured to detect physical interactions of a user with the shank and control the locking mechanism. A method of operating the electronic padlock includes detecting physical interactions of a user with a shank of an electronic padlock, comparing the detected physical interactions with a stored predetermined series of physical interactions, and transitioning from a locked state to an unlocked state responsive to determining that the detected physical interactions match the predetermined series of physical interactions.

Abstract: A wireless, electronic interchangeable locking core that includes an outer housing and a locking core that is rotatable via an external handle between a locked position and an unlocked position. The handle is prevented from rotating the locking core unless wirelessly-provided authorization credentials are validated and/or a pattern of physical input interactions with an electronic sensor is matched with a stored pattern. The pattern may be defined, for example, as a sequence of short and long interactions with a button, light sensor, touch panel, or the like. The electronic interchangeable locking core may include a battery and be configured for installation in small format interchangeable core (SFIC) housings.
