Abstract: An access control system including bi-directional communication between a controller and peripheral authentication devices utilized for selectively accessing a locked door is provided. The access control system provides components and circuitry to enable a user to securely assign and designate any card reader compatible card as an appropriate programming card and thereby activate or deactivate users and/or cards. The present invention further provides encrypted communication between the controller device and a PC.

Abstract: An electro-mechanical lock for gates and similar applications having a latch assembly and a strike assembly. The strike assembly has a strike which is self-adjusting to accommodate misalignment to guide the strike roller into proper engagement in the latch assembly. The latch assembly has a latch which is operably connected to a solenoid by a trigger and transfer mechanism which provides pre-load capability.

Abstract: A door release system including a capacitive circuit that includes a touch bar, a microprocessor within the touch bar programmed with noise-discrimination software to sense touching of the bar, and at least one micro-switch within the bar to function as a back-up that picks up movement of the bar to release the latch should the capacitive circuit fail. Optionally, a sign illuminated by LEDs and an antimicrobial coating/treatment may be applied to the bar. The system is intended for use on magnetically locked doors. The addition of the micro-switches that are actuatable by continued movement on the touch bar after the bar is initially touched provides a redundant access function initiated by other than the capacitive effect of human touch, which is expected to simplify use and ease accessibility for personnel with prosthetics or who may otherwise have their hands occupied.

Abstract: A device for transferring electrical power between a frame and a closable member such as a door includes a first housing and face plate disposed in an opening in the frame and a second housing and face plate disposed in an opening in the closable member edge. The openings are positioned so that when the closable member is closed the openings are aligned. A hollow elbow assembly is rotatably disposed and secured in each hole. A tube having a pivot guide at each end is rotatably and axially slidable in each elbow assembly. A slot in each elbow assembly allows the tube to pivot. A wire bundle in the tube is connectable to wire leads. Boots may be supplied around the tube/elbow assemblies' junctions to exclude water. Thus, the wire bundle is fully contained within a protective, articulated, armored sheath to prevent wear, chafing, breakage, and vandalism.
