An electronic straight shackle lock apparatus and system. Aspects of the present disclosure provide for a keyless, electronic straight shackle lock that provides a high level of security at a relatively low cost and without any opening for a physical mechanical key. Certain embodiments provide for an easy-to-use and compact adapter for a keyless, electronic straight shackle lock and the ability to manually override the electronic lock. Certain benefits and advantages of the present disclosure include a compact and flexible locking system that can be installed on many different enclosures and doors that can be locked and unlocked using an electronic device via a wireless signal.

An illumination system is provided for an access door may include an elongated illumination housing configured to be coupled to at least one of an upstanding jamb and a corresponding jamb casing extending along the one side of the access door, an elongated light transmissive cover coupled to the illumination housing, an elongated light pipe received within the illumination housing, an illumination source housing operatively coupled to one end of the light pipe, an illumination source disposed within the illumination source housing and configured to produce and transmit visible light into the light pipe so as to be visible through the light transmissive cover, a source of electrical power, and a control unit configured to selectively apply electrical power from the source of electrical power to the illumination source to produce the visible light.

A door-lock system includes a door latch adapted to be coupled to one of a door or to a structure defining the passageway through which the door restricts passage. The door-lock system may further include a latch lock adapted to be coupled to the other of the door or to the structure defining the passageway to selectively mate with the door latch to block the door from opening.

Disclosed are an electronic lock (100) and a light colour control method for the electronic lock (100). The electronic lock (100) comprises a lock body (1), a lock hook (2), at least two shifting beads (3), a lock shifter (4), a motor (5), a motor actuator (6), and an elastic member (7), wherein the shifting beads (3), the lock shifter (4), the motor (5) and the motor actuator (6) are mounted in the lock body (1), the motor actuator (6) is mounted on the motor (5) and interlinked with the lock shifter (4), the lock hook (2) is mounted on the lock body (1) and is able to move with respect to the lock body (1), the shifting beads (3) cooperate with the lock hook (2) such that the electronic lock (100) is transformable between a locked state and an unlocked state, and the elastic member (7) is mounted in the lock body (1) and exerts an acting force on the shifting beads (3) in opposite directions towards the lock hook (2) so that the shifting beads (3) do not exert any acting force on the lock shifter (4) during a progress of unlocking and locking. In the electronic lock (100), the shifting beads (3) do not exert any acting three on the motor (5) during a progress of unlocking and locking, and the motor (5) is in an unloaded state, thereby lowering demand for power supply and for the voltage and power of the motor (5), reducing energy loss and prolonging the service life of the electronic lock.

A latch (10) includes a rotatable jaw (18) that engages and holds a striker (32) in a latched position. A rotatable pawl (28) in an engaged position is operative to hold the jaw in the latched position. Movement of the pawl to a disengaged position enables the jaw to move to an unlatched position and to disengage the striker. The pawl is movable from the engaged position to the disengaged position through operation of either an electrical actuator (84) or through movement of an actuating end (26) of the pawl by a cable (36).

An unlocking device and a door lock are disclosed. The unlocking device includes a signal generating module configured to generate an unlock signal and a control module. The control module comprises a main control unit communicated with the signal generation module, and a drive unit connected with the mechanical lock body. The main control unit is configured to receive the unlocking signal generated by the signal generating module, and control the drive unit to drive the mechanical lock body to unlock according to the unlocking signal received.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

Locking device is disclosed for parcel boxes or lockers. The device comprises a user operable handle and a lock mechanism comprising a motor to rotate a pinion to move a rack attached to a handle-blocker and to a deadbolt. The handle-blocker controls transition of the user operable handle between open and closed positions due to movement of the rack, and simultaneously the deadbolt is configured to move between locking and unlocking positions. In the closed position, the handle-blocker and the handle-body have a linear connection with each other and in open position this connection is lost. The handle may be activated by tapping the handle-cover, or by using an RFID, NFC or by mobile technologies. A method to operate opening and closing a parcel box locked with the locking device allows one or more users to access the parcel box via software application paired with the device.

A system for use with an autonomous working machine such as a robotic lawn mower. The system may allow communication (directly or indirectly) between the machine and a gate or other barrier opening to allow unattended or remotely-controlled passage of the machine through the gate. In some embodiments, the mower may include a vision system operable to detect unknown objects within an area adjacent to the gate.
