A latch apparatus coupled to an aircraft component can comprise a latch assembly moveable between unlatched and latched configurations, an actuation system coupled to the latch assembly and operable to move the latch assembly from the latched configuration to the unlatched configuration, the actuation system including an electromagnet assembly magnetically coupled to the latch assembly, and a control system operably coupled to the electromagnet assembly. The control system can be configured to magnetically uncouple the electromagnet assembly from the latch assembly to cause the latch assembly to move from the latched configuration to the unlatched configuration. Related methods are also provided.

A magnetic release mechanism for use with underwater fishing equipment includes a base plate having a slot for receiving a buckle, and a recess for receiving a release plate. A permanent magnet positioned proximate the recess generates a first magnetic field for magnetically coupling the release plate to the base plate. An electromagnetic coil positioned proximate the permanent magnet is configured to selectively generate a second magnetic field when energized. A magnetic field sensor is positioned proximate the recess. A controller is operatively coupled to the magnetic field sensor. The controller may be configured to monitor the magnetic field sensor to detect the presence of a third magnetic field and, in response to detecting the presence of a third magnetic field, output a signal indicating that the release plate is magnetically secured within the recess.

An electric strike having a keeper arranged to pivot about a shaft extending in a longitudinal direction, a lock lever for locking the keeper in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever. The strike is provided with a bearing element arranged to bear against the lock lever. The bearing element acts as a stop against possible lateral motions of the lock lever. Such motions may be induced by trying to force open the door lock when the lock lever is in the locking position. By providing the bearing element, it is avoided that the forces due to these lateral motions are exerted onto the second shaft that connects the lock lever to the strike.

An electric strike having two keepers arranged to pivot about respective shafts extending in a longitudinal direction, a lock lever for locking the keepers in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever. The keepers form side walls of a bolt cavity and are arranged to pivot between a door-locking position and a door-releasing position. Therefore, the bolt may exit the cavity in two directions, e.g., a first direction for a left-handed closure member and a second direction for a right-handed closure member. The strike can thus be mounted in the same orientation for both left-handed and right-handed closure members.

A locking apparatus for a rollup door, comprising a striker member, latch assembly including a latch, a release lever, a trigger, a cam and a solenoid. The latch assembly may also include a limit switch for detecting when the latch assembly is in an unlocked position. The locking apparatus can be electronically unlocked or it can be unlocked manually by a user by actuating the solenoid which causes the latch to release the locked striker member.

A device for unlatching and opening a door of a building to allow exit in the event of a hazardous condition comprises an actuator housed in a supporting frame connected to a strike plate and having a face part that pushes against a latch bolt on the door to disengage the latch bolt from the strike plate. The actuator can be rotated, about a hinge axis, outward from the supporting frame for adjustment of its stroke. A spring or gravity-operated device is provided to urge the door toward its open condition when the latch is released.

An electric strike for use with a sliding door is provided. The strike comprises a housing defining a cavity including first and second walls, each having first and second slots defined therein. A keeper is disposed within the cavity and movable between latched and unlatched positions. The keeper includes first and second ends, wherein each includes respective outwardly extending first and second keeper pins. The first and second keeper pins extending from each end of the keeper are disposed in the respective first and second slots. A blocking member is pivotably mounted to the housing and includes first and second portions. The second portion of the blocking member is engaged with the first keeper pin when the first portion of the blocking member is selectively engaged with a plunger of an actuating mechanism in the first engaged position to selectively maintain the keeper in the latched position.

An electromechanical component for a locking mechanism is provided. The locking mechanism includes a latching component having a latch member reciprocally movable between a locked orientation and an unlocked orientation. The electromechanical component comprises a drive member configured to be coupled to the latch member, an actuator operably coupled to the drive member, a temperature sensor for sensing an ambient temperature associated with the locking mechanism; and a printed circuit board (PCB) in communication with the temperature sensor and the actuator. When the PCB receives a control signal to move the latch member between the locked orientation and the unlocked orientation, and the temperature sensor senses that the ambient temperature is below a predetermined threshold temperature, the PCB is configured to direct a pulsed current signal to the actuator to move the latch member between the locked orientation and the unlocked orientation.
