Abstract: A bracket assembly for mounting a display monitor to a support structure has a back plate configured to mount to the support structure; a back plate extension disposed along one side of the back plate; a front plate configured to mount to the display monitor; a front plate extension disposed along one side of the front plate; a contact surface formed by the front plate extension overlapping the back plate extension, the contact surface transferring a weight of the monitor to the support structure; and a volume at least partially enclosed by the front and back plates and extensions for housing an electronic component between the display monitor and the support structure.

Abstract: A switch assembly actuated by passive infrared radiation for operating a light in a space, the switch assembly including an optical system which senses infrared radiation over a 180.degree. range in horizontal plane including two separate vertical fields of view, a generally horizontal "look-out" field and a vertical semi cone-shaped "look-down" sensing field for directing to a common sensing element passive infrared radiation produced by a person moving within the sensing field of the switch assembly, the sensing element connected to a control circuit which responsively turns on the light, maintains the light on while the person remains in the space, and turns the light off automatically when the person leaves the space. The switch assembly includes a one-piece optical shell enclosed within a housing which is adapted for installation in a conventional light switch box in room.
