A washing machine includes a housing equipped with an inlet, a door to open or close the inlet and including a latch with a locking hole formed at the latch, a door locking device including a locking member with a locking bar formed at the locking member to be inserted to the locking hole, and configured to lock or unlock the door according to whether the locking member is fixed, an automatic door opening device to deliver driving power to the locking member so that the locking bar is removed from the locking hole, and a controller to control the door locking device to unlock the door by unfixing the locking member, in response to a completion of a washing course and to control the automatic door opening device to open the door by delivering the driving power to the locking member in response to the door being unlocked.

A remotely controlled cabinet assembly includes a cabinet unit that includes a central cabinet and a door that is hingedly coupled to the central cabinet. A plurality of locking units is each coupled to the central cabinet. Each of the locking units releasably engages the door for locking the door on the central cabinet. A control unit is coupled to the cabinet unit and the control unit is electrically coupled to each of the locking units. The control unit actuates each of the locking units to disengage and thusly unlock the door on the central cabinet. A keypad is coupled to the door and each of the locks disengages the door when an alpha-numeric code is entered into the keypad. An electronic device is carried by a user and the electronic device transmits an unlock command to the control unit for remotely unlocking the door on the central cabinet.

An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input is connected to an actuator that linearly displaces the input shaft, and the output shaft is connected to a locking member of the exit device. The over-travel mechanism includes a link coupled to the output shaft, and a preloaded elastic member transmits force between the input shaft and the link. Movement of the input shaft from a first input shaft position to a second input shaft position causes the elastic member to urge the link from a first link position toward a second link position. Movement of the input shaft from the second input shaft position to a third input shaft position causes the elastic member to elastic member to elastically deform without moving the link from the second link position.

An automatic door opening system including a door having a top portion, a bottom portion, a hinged portion, and an opening portion. The system includes an opener connected to the door adjacent the opening portion and configured to selectively receive electrical current. The system includes a magnet disposed on the opening portion of the door such that the magnet is adjacent the opener when the door is in the closed position. The system includes a microcontroller in electric communication with the electromagnet wherein a memory contains processor-executable instructions to receive a door activation input and, in response to receiving the door activation input, activate the electromagnet to apply a magnetic force against the magnet and push the door between the closed position and the open position. The system may also include a closer configured to selectively return the door to the closed position.

An electric lock includes a housing, a keypad module and a lock assembly. The keypad module is arranged on the housing. The keypad module includes a key panel, an electrode pad, a circuit board and a spacer. The key panel is marked with a plurality of key characters. The electrode pad is arranged on an inner side of the key panel, and the electrode pad has a plurality of key electrodes corresponding to the plurality of key characters respectively. The circuit board includes a plurality of key circuits. Each of the key circuits is configured to generate a key signal when contacting a corresponding key electrode. The spacer is configured to form a gap between each of the key circuits and the corresponding key electrode. The lock assembly is electrically connected to the keypad module for performing locking and unlocking operations according to the key signal.

A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

An electronic lock, such as a deadbolt, with a locking device movable between a locked position and an unlocked position. The lock includes a key fob including a RFID circuit indicative of a valid access code for the locking device. A circuit is provided that is configured to control movement of the locking device between the locked position and the unlocked position. The circuit includes a sensor, such as a contract sensor or a proximity sensor, which detects when a user is within range of a RFID device. When this happens, the sensor is configured to generate an electrical signal, which is used to activate the RFID device for a predetermined period of time. If the RFID device reads a valid access code, the device is unlocked.

A lockset with a latch assembly having a bolt movable between an extended position and a retracted position. The lockset includes a motor configured to move the bolt between the extended position and the retracted position. A controller is provided that is configured to electronically control the motor to control movement of the bolt between the extended position and the retracted position responsive to receiving a valid authentication from an authentication device. The lockset includes a receiver connected to an antenna to detect an incoming wireless signal transmitted from an authentication device. The controller includes an angle of arrival sensor configured to determine a distance and a direction to the authentication device by analyzing a wireless phase and timing of the incoming wireless signal transmitted by the authentication device. The controller is configured to control movement of the bolt between the extended and retracted positions based, at least in part, on the distance and the direction to the authentication device.

A mail delivery assistance system comprises a letterbox for receiving mail consignments that has an opening and an electronic locking mechanism, a data processing device that comprises a database having an address file in which a respective addressee is associated with a building address, and a reader for capturing mail consignment data of a mail consignment. The reader, during operation, is communicatively connected to the data processing device in order to send the mail consignment data to the data processing device. The data processing device checks whether the mail consignment data match an addressee in the address file, and, if this is the case, generates a control signal for the locking mechanism in order to open the opening and to allow delivery of the mail consignment.
