A latch dogging assembly comprises an electromagnet and an actuator mounted on a bracket. A guide slide is pivotally mounted on the bracket with a lead block coupled to the guide slide. A guide pin rides along an inner surface of the bracket causing the guide slide to pivot. A pawl is slidably engaged with the guide slide. A guide link includes a post. An armature is mounted to the panic bar and the post engages the pawl. When the actuator is energized to move the lead block, the pawl engages the post to pivot the armature and thereby cause the panic bar to move from the extended position to the depressed position. When the electromagnet is energized the armature is magnetically held preventing reverse pivoting of the guide link. A method for fully retracting a door latch is also provided.

What is presented is a power-transfer system that provides resonant inductive power from a first object to a second object, which is adjacent to the first object. The system includes a first transformer portion that is positioned on the first object and having a first core portion. The first core portion includes a transmit unit configured to transfer an electromagnetic field to the second transformer portion. The first core portion also includes first circuitry that allows the transmit unit to transfer the electromagnetic field. The second transformer portion is positioned on the second object and has a second core portion. The second core portion includes a receiver unit configured to receive the electromagnetic field. The second core portion also includes second circuitry that allows the transmit unit to transfer the electromagnetic field.

A device for measuring voltage across a remote load includes a power supply configured to output a first output voltage to the remote load. A switch is selectively movable from a closed position to an open position. A measuring circuit measures a load voltage across the load when the switch is in the open position and determines a voltage difference between the first output voltage and the load voltage. The measuring circuit adjusts the first output voltage to a second output voltage to compensate for the voltage difference. A second A/D converter can also be coupled to the power supply. The second A/D converter measures a voltage across a resistor such that a change in the voltage indicates a change in the load voltage. The power supply is then adjusted to output a second output voltage to compensate for any change in load voltage.

An electromechanical cable lock system comprising an electromechanical locking mechanism including a cable having at least one plug end receivable in the locking mechanism and a plurality of slidable locking plates engageable with the plug in said locking mechanism. At least one of the locking plates is capable of movement in a first direction different from the movement of a second of said locking plates in a second direction. The locking plates are driven by a motor-driven cam mechanism. The system includes a card reader or other credential verifying device and an electronic controller for activating the locking mechanism, The system also includes a barrel lock for over-riding the electronic controller. A plurality of features can detect and alarm in the event of tampering or unauthorized entry.
