A washing machine is disclosed. A washing machine according to one embodiment of the present invention comprises: a door for opening and closing a laundry inlet; a magnetic body included in the door; a processor; and a door lock switch module including a door lock key which moves in accordance with the opening and closing of the door so as to lock or unlock the door, a first switch electrically connected on the basis of movement of the door lock key to a locked position, and a second switch connected in series with the first switch and electrically connected in response to an approach of the magnetic body, wherein the processor receives a signal generated by connecting the first switch and the second switch, detects the locking of the door, and proceeds to perform the washing cycle process of the washing machine. Other embodiments are possible.

A lock management system manages access to a controlled environment by locking or unlocking a door. The lock management system can actuate one or more components of a lock system to lock or unlock the door. To determine whether to lock or unlock the door, the lock management system can establish a connection with one or more devices. The lock management system can receive an access credential via the connection and authenticate the access credential. Based on authenticating the access credential, the lock management system can lock or unlock the door. The lock management system can monitor a door status and/or door activity and provide alerts to a user computing device.

An electro-mechanical lock is provided for a door. The lock includes inner and outer lock components mounted on opposite sides of the door and a tube extending between the inner and outer lock components, the tube being configured to receive a spindle extending through the door. The tube includes an electrical conductor integrated with the tube as a one-piece construction for transmitting electrical power and/or control signals between first and second electrical connectors at the inner and outer lock components. The tube is less fragile than conventional double tube arrangements in locks and thus can be more easily cut to length and installed at the door, improving reliability and cost effectiveness of methods of installation.

An electronic lock includes a latch assembly that has a latch housing and a bolt. The bolt is movable between an extended position and a retracted position. The electronic lock includes a controller connected to a circuit board. The controller is configured to electronically control movement of the bolt between the extended position and the retracted position. The electronic lock includes an exposed conductive touch member. The conductive touch member is in electrical communication with the controller. The electronic lock includes an insulating arrangement positioned between the conductive touch member and the circuit board. The electronic lock includes a housing at least partially surrounding the conductive touch member. The housing is electrically isolated from the conductive touch member by at least a portion of the insulating arrangement.

Provided is a locking/unlocking device that accurately detects an opening/closing state of an opening/closing device and optimizes timing to lock or unlock.

The locking/unlocking device includes a drive unit that drives a lock mechanism of the opening/closing device, a magnetic detection unit that detects a change in a magnetic field based on a change in the relative position between a movable section and a fixed section of the opening/closing device, and a control unit that determines an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection unit and activates the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state.

A lock (1) with an exterior activation sensor (2) includes an interior electromechanical mechanism (3) with a corresponding power supply unit (4) and an exterior activation sensor (2) situated on the external part of the locker, and which is used in community lockers or similar, wherein the exterior activation sensor (2) contains at least two respective internal electrical contacts (5) which, by means of a conductive circuit (6), reach the inside of the lock and connect in parallel to the interior poles of the circuit (4a) of the power supply unit (4).

Disclosed are a control method for an electronic lock and an electronic lock based on the control method. The electronic lock has a simple structure, and jointly control a snap hole on the handle with a telescopic body of the electromagnet located on the lock body base and a push rod controlled by the unlock mechanism. The telescopic body of the electromagnet has the characteristics of self-holding function when power off through the first permanent magnet, which not only the hidden danger of illegal unlocking through mechanical structure is solved, but also the power consumption of electronic lock in preventing illegal lock opening can be greatly reduced. The market's technical requirements for electronic locks can be met, and high promotion value can be obtained.

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.
