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 secure beverage container may include a body having a first end, a second end opposing the first end, a first longitudinal side extending between the first end and the second end, and a second longitudinal side opposing the first longitudinal side and extending between the first end and the second end, the first end being closed, the second end being open. The body may define a cavity to receive a beverage fluid. The secure beverage container may include a lid to be received by the second end to seal the cavity in the body, and a powered locking device. The secure beverage container may include an access control device coupled to the powered locking device and configured to cause the powered locking device to switch between the locked state and the unlocked state based upon a security token.

A lock indicator and a mechanical lock assembly, comprising: a switch; a transmitter coupled to a power source; and a bolt member moveable between a retracted position and an extended position with respect to the housing, wherein the switch is configured to engage the bolt member and is actuatable by the bolt member to determine the position of the bolt member, and the transmitter is configured to transmit a signal indicative of the position of the bolt member to a remote device.

An animal door unit comprising a front panel, a left rear panel, a left guide, a right rear panel, and a right guide, wherein the front panel comprises an entrance; and a door plate having a plurality of guide holes, the door plate configurable in a retracted state and an open state, wherein, in the retracted state, the door plate traverses the entrance, and wherein, in the open state, the door plate does not traverse the entrance. The animal door unit may include a motor disposed within a module case; and a sprocket in rotational communication with the motor, wherein the sprocket interfaces with the plurality of guide holes, such rotational movement of the sprocket inducing linear movement in the door plate.

A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

An apparatus includes an enclosure, a central processing unit, a power source, a first distance measuring device, a first compressible member, and a first housing pin, where the central processing unit is electrically coupled to the power source and the first distance measuring device. A first end of the first compressible member is mechanically coupled to a first end of the first housing pin and a second end of the first compressible member is mechanically coupled to an inner surface of the enclosure. The first distance measuring device positioned at the second end of the first compressible member, where the first distance measuring device is configured to measure a first distance to the first end of the first housing pin. A first key pin of a key structure disposed in the enclosure, where the first key pin is configured to compress the first compressible member the first distance.

A universal add-on device for controlling a movable barrier opener to open and close a movable barrier includes a control module which wirelessly communicates with a user's mobile electronic device. The opener includes a hand-held remote transmitter having a push-button switch. The hand-held remote transmitter is configured to transmit wireless signals to the opener for initiating the opener to move the movable barrier upon actuation of a push button of the push-button switch. The control module is either connected to an actuator to physically actuate the push-button switch of the hand-held remote transmitter or electrically connected in parallel with the push-button switch to electrically actuate the push-button switch of the hand-held remote transmitter. The device enables a manufacturer's compatible remote transmitter or a universal remote transmitter to be utilized to control the movable barrier using the user's mobile electronic device such as a smart phone.

A locking device is proposed to lock and/or to unlock a movable closure element like a door, a lid, etc. in a lockable object like a building, a ship, a vehicle, a train or the like, wherein the locking device has an electric control unit and/or a drive unit to control and/or to drive a movement of the movable closure element.
