Abstract: An access control system for restricting access through a passageway includes a shaft rotatable about a central axis; a barrier fixed to the shaft to rotate therewith; and a brake assembly. The brake assembly includes a sun gear rotatable about the central axis, a carrier, and a ring gear, wherein one of the carrier or the ring gear is fixed against rotation and the other of the carrier or ring gear is connected to the shaft to rotate therewith. A plurality of planet gears are rotatably connected to the carrier, each planet gear being disposed between and engaging with each of the sun gear and the ring gear. An electromagnetic brake comprises an electromagnet and an armature. The armature is connected to or integral with the sun gear to rotate and move axially therewith. At least one of the electromagnet or the armature is moveable between an operative position and an inoperative position.

Abstract: A system for monitoring the movement of people through a passageway comprising two or more time of flight sensors deployed across the passageway in a direction substantially transverse to the direction of movement of a person or object through the passageway. The system further comprises means to determine data regarding people or objects passing through the passageway based on the time of flight of a signal measured by the two or more sensors.

Abstract: Turnstile apparatus comprising a plurality of turnstile lanes, a camera mounted to view the lanes in its field of view and a remote controller, connected over a network to the camera and lanes, the controller having a display associated with it and means for controlling operation of the lanes, the camera being adapted to transmit video images of its field of view to the controller; the controller being adapted to display the video from the camera and further adapted to generate buttons, each button being associatable with a particular lane, the button being moveable to a position on the screen where it is in the vicinity of the lane, wherein operation of the button by a user controls operation of its associated lane, including operating a barrier, forming part of the lane, to open.

Abstract: A floor protector for a security access system, comprising a rigid floor assembly having front and rear edges, the floor assembly comprising at least one floor plate and a base mounted underneath the floor plate, the base being at least partially spaced from the floor plate enabling cabling to pass between the two, and elastomeric entry and exit ramps supporting the front and rear edges of the floor assembly; wherein the base has protrusions at its front and rear edges which locate within respective grooves in respective elastomeric ramps, spaced a distance above the lower surface of the ramp, so as to support the base spaced above the whole or a major part of the floor that it overlies.
