  • Patent number: 10487543
    Abstract: Embodiments provide a lock including an actuator that is movable between an unlocked position and a locked position, and a bolt that is movable between an extended bolt position and a retracted bolt position independent of the position of the actuator. In the extended bolt position, the bolt extends outside a body of the lock. A coupling element is arranged between the actuator and the bolt and is movable between an extended coupling position and a retracted coupling position in response to movement of the actuator between the locked position and the unlocked position. A first biasing element biases the coupling element toward the retracted coupling position, and a second biasing element couples the coupling element to the bolt and is structured to bias the bolt away from the coupling element and towards the extended bolt position.

  • Patent number: 10329798
    Abstract: In a method of monitoring lockout procedures, a first lockout device is secured with a first component in a lockout condition to block operation of the first component, and a corresponding first data signal is received, with the first data signal including at least a first identification code corresponding to the first lockout device. A second lockout device is secured with a second component in a lockout condition to block operation of the second component, and a corresponding second data signal is received, with the second data signal including at least a second identification code corresponding to the second lockout device. The first and second data signals are monitored to determine an order in which the first and second lockout devices have been locked out, which is compared with a predefined lockout procedure. An alert is provided if the order is inconsistent with the predefined lockout procedure.

  • Patent number: 10262484
    Abstract: Disclosed are methods, systems, and computer-readable media for wireless key management for authentication. Authentication includes transmitting a request to a locking device, transmitting a security challenge to the mobile device, and transmitting a response to the challenge and an encrypted user profile for the locking device. The response includes data generated with an access key that is stored by both the mobile device and the locking device, and the user profile is encrypted by a server using a secret key that is stored by the server and the locking device. Authentication further includes verifying the response to the challenge, where the response is verified using the access key, and validating additional data from the mobile device.
