  • Patent number: 9019067
    Abstract: An electronic lock with power failure control circuit includes a lock mechanism having a latchbolt movable between extended and a retracted positions and an electrically powered lock actuator to lock and unlock the latchbolt. The power failure control circuit includes a microcontroller and the lock is connected to a primary power source and an auxiliary power source, preferably supercapacitors and charger that can be turned on by the microcontroller and off when the charger signals a full charge. A power monitor circuit detects low voltage on the primary power supply and sets a power failure interrupt causing the microcontroller to execute power failure instructions that control the actuator so that the lock is placed into a desired locked or unlocked final state during the power failure. upon detection of the return of good power, the system resets the lock.

  • Patent number: 8960372
    Abstract: An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.

    Abstract: An electronic lock controller comprises a trusted time provider, a near field communication transceiver, and a logic processor. The trusted time provider provides a trusted time value. The near field communication transceiver receives power and a digital credential from an operator-side interface device. The logic processor produces an open or close command for an electromechanical lock based on the trusted time value and the digital credential. The electronic lock controller is powered solely by the near field communication transceiver.

  • Patent number: 8291733
    Abstract: An electric door lock includes a transmission wheel driven by a motor and incorporating a spring with a driving end to drive a driven wheel. The transmission wheel and the driven wheel are rotatably sleeved around an inner drive tube connected to an inner handle. A spindle is inserted into the inner drive tube and has an operating end exposed from the inner handle. The driven wheel is connected integrally to the spindle for rotation. Preferably, a coupling piece extends through an arc-shaped slot in the inner drive tube and interconnects the driven wheel and the spindle.

    Abstract: A driving device for an electric lock latch, comprises a housing, a motor having a power output shaft connected to a drive shaft with an external thread on a part thereof, an unequal diameter coil spring having a cylindrical spiral in the middle thereof screwing with the drive shaft, and a first and second conical spiral on both end thereof not screwing with the drive shaft, and a lock latch secured to the second conical spiral. The drive shaft is driven and rotated by a motor to pass the rotation power to the cylindrical spiral, and a rotary motion of the drive shaft is converted into a linear motion of the unequal diameter coil spring for moving the lock latch to change the locked and unlocked state of the lock device. Accordingly, the lock structure and the installation thereof may be simplified and the power-saving effect is achieved.

  • Publication number: 20120169453
    Abstract: An electronic lock with power failure control circuit includes a lock mechanism having a latchbolt movable between extended and a retracted positions and an electrically powered lock actuator to lock and unlock the latchbolt. The power failure control circuit includes a microcontroller and the lock is connected to a primary power source and an auxiliary power source, preferably supercapacitors and charger that can be turned on by the microcontroller and off when the charger signals a full charge. A power monitor circuit detects low voltage on the primary power supply and sets a power failure interrupt causing the microcontroller to execute power failure instructions that control the actuator so that the lock is placed into a desired locked or unlocked final state during the power failure. upon detection of the return of good power, the system resets the lock.

  • Publication number: 20120167646
    Abstract: A sensing system senses whether or not a lock's bolt (140), e.g. deadbolt, is aligned with a hole (150) which the bolt is to engage in the locked state. In electronic locks, the bolt is not driven into the hole until the sensing system indicates that the bolt is aligned with the hole. Another sensing system senses the position of the bolt and/or a dead-latch bar (1310). This sensing system is spaced from the bolt's end engaging the hole in order not to interfere with the alignment sensing. The two sensing systems are used to determine whether the lock is locked or unlocked. A magnet system provides alignment assistance to align the bolt with the hole before the bolt is driven into the hole. Position encoding for lock and non-lock devices, and other features and embodiments are also provided.

    Abstract: A coded lock assembly is introduced in order to improve upon existing coded locks used to control access to protected areas. The lock assembly contains several micro-switches within the anterior portion that can be pushed by a push button on the posterior portion of the lock assembly. In order to unlock the lock assembly, the user must turn an exterior drive handle to the proper position and press the push button. A predetermined sequence of handle turns and push button presses is required to unlock the lock.

  • Publication number: 20110185779
    Abstract: An improved method of rotating the lockrod of a tool storage unit to the “locked” or “unlocked” position by use of a linear actuator to rotate the lockrod actuator, where the linear actuator operates electrically, allowing for control by any remotely or automatically operated system. The tool storage unit locking mechanisms include a center-neutral key position that rotates 90 degrees in either direction from center to lock and unlock the unit. This design allows a standard key to operate the locking mechanism, but also allows a secondary mechanism (such as an electromagnetically driven mechanism) to directly operate the lock. Due to its specifics, the design would also allow for retrofitability.
