Abstract: A system and method for tensioning a belt drive in a remotely controlled video camera is provided in which the belt drive tensioning system has an accessory pulley. A receptacle has a substantially circular opening and an extension. The extension is disposed partially around a periphery of an end of the circular opening and projects partially over the opening. A drive pulley is substantially coplanar with the accessory pulley. A housing has a body wall, a first longitudinal axis and a substantially circular tab provided at an end region of the body wall. The substantially circular tab has a second longitudinal axis which is parallel and eccentric to the first longitudinal axis. A drive pulley is substantially coaxially aligned along the first longitudinal axis and is rotatably coupled to the housing. The housing is configured to engage the receptacle in a first position where the drive pulley is at a first distance from the accessory pulley.

Abstract: A system for mounting a recessed electrical or electronic device housing in (behind or above) a wall or ceiling surface utilizes a pair of resilient spring clips that are threadedly attached to respective diametrically opposed threaded screws. The threaded screws are accessible from the front surface of the housing so that the recessed-mounted housing may be inserted into a hole in the wall or ceiling material and fixedly mounted therein by rotating the screws from the front (ceiling or wall) surface of the housing. Each spring clip includes a bearing tab that bears down against the back side of the wall or ceiling material to sandwich the ceiling material between the bearing tab and an annular flange on the front, open end of the housing. Each threaded screw is journaled in a shouldered bushing which is press-fitted into the housing annular flange.
