A covering (200) for an opening in a building and a sensor assembly (500) is disclosed. The covering (200) comprises a panel (201) moveable between an open position and a closed position, and to an intermediate position between the open position and the closed position. The sensor assembly (500) is configured to sense the position of a locking member (205) of the covering and to transmit signals indicating the position of locking member (205). Methods of installing a sensor assembly (500) on a covering (200) of an opening of a building are also disclosed.

A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

A locking mechanism is provided for a portal closure that includes a first side, and a second side The portal closure including a latch movable into and out of engagement with a latch receiver and a latch driving device coupled to the latch for moving the latch into and out of engagement with the latch receiver The latch driving device includes a controllable lock member movable between a locked position where the latch is fixedly positioned in the latch receiver and an unlocked position where the latch is capable of being disengaged from the latch receiver and a second side latch driving device mover disposed on the second side of the portal closure. The locking mechanism includes a first side latch driving device mover disposed on the first side of the portal closures, and coupled to the latch driving device for moving the latch driving device to cause the latch to move into and out of engagement with the latch receiver. A signal generator is provided for generating a human detectable signal. A lock actuator is coupled to the controllable lock member for moving the locking mechanism between a first normal position wherein the second side lock driving device is capable of being moved between an unlocked position to permit the latch to be disengaged from the latch receiver and a locked position where the latch is prevented from being disengaged from the latch receiver; and a second emergency position wherein the second side lock driving device is in the locked position, and the signal generator is actuated to generate a human detectable signal. A power source is provided for powering the signal generator when the locking mechanism is in the second emergency position. A switch is coupled between the power source and the signal generator for controlling the flow of current between the power source and the signal generator.

A bi-directional electronic lock device includes a lock mechanism and a control unit. The control unit includes a position determining component driven by the lock mechanism to rotate, a sensor configured to generate a specific sensing signal for each of three positions with respect to the position determining component, a direction determining module that actuates the lock mechanism to move from a locked state toward an unlocked state, and that generates a directional signal based on the sensing signals, and a control module that is configured to, in response to receipt of the directional signal, set the lock mechanism, based on the directional signal, to operate in one of a left setting and a right setting.

A vehicle equipment seal device includes a main body portion, a bolt portion, a metal wire connection portion and a lock structure. The main body portion has a connection surface. The bolt portion is inserted into the main body portion. The metal wire connection portion has one end fixed on the connection surface of the main body portion, and the other end provided with the bolt portion. The lock structure is arranged in the main body portion, wherein the lock structure includes a motor and a sensor, and the sensor is used to position a turning position of the motor, thereby determining whether the lock structure locks the bolt portion or unlocks the bolt portion.

A low-voltage, direct current apparatus for controlling a door. The apparatus may comprise a mounting bar configured to be coupled to the door and a latch coupled to the mounting bar. The latch may comprise a locking lever, and an actuator may be configured to move the locking lever between a locked position in which the locking lever prevents movement of the latch to an unlocked position in which the locking lever allows movement of the latch.

A lock for permanent attachment to a movable freight container cargo door as a replacement for a prior art hasp or a prior art keeper. The lock is configured for permanent attachment to the cargo door using pre-existing hole locations for the prior art hasp or keeper. The lock comprises a straight shackle and a c-shaped lock body and is configured to retain a door handle between the shackle and the back of the c-shaped lock body. The shackle is locked into the lock body using a shackle lock element that engages with a groove in the shackle. The shackle groove is perpendicular to the shaft of the shackle. The shackle lock element is pressed into the groove using by one or more springs in linear direction that is perpendicular to the length of the shackle and perpendicular to the groove, and released from the groove through by a lock module, which could be a lock cylinder or an electronic lock module. Axial movement of the shackle to prevent the shackle from being completely removed from the lock body is accomplished by a screw in the lock body that rides into a longitudinal slot in the shaft of the shackle.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

A sensor assembly includes a sensor located within an opening formed in a strike box of the strike assembly. The sensor, which could be an optical, mechanical, continuity, inductive, ultrasonic, and/or mechanical sensor, is configured to detect whether the bolt of the bolt assembly is encompassed by the strike box. The sensor assembly is configured to interact with a surface of the bolt when the bolt is located within the opening.

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.
