Abstract: A system is disclosed for extending the effective operational range of an infrared remote control system. The infrared remote control system is of the type having a remote control unit with a housing defining an interior component compartment. An infrared transmitter is at least partially contained within the component compartment while the controlled device includes an infrared receiver. The extender system includes a first repeater which is contained within the component compartment closely adjacent the infrared transmitter. An infrared receiver is contained within the first repeater and generates an output signal representative of the infrared signal received from the remote control unit. A radio transmitter at the first repeater then transmits a radio signal to a radio receiver at a second repeater which is physically adjacent the controlled device or devices.

Abstract: A system for extending the effective operational range of an infrared remote control system of the type having a remote control unit with an infrared transmitter and a controlled device having an infrared receiver. The system includes a first repeater positioned physically in the area where the remote contol unit will be used. An infrared receiver is contained within the first repeater and generates an electrical output signal representative of the infrared signal received from the remote control unit. A radio transmitter at the first repeater then transmits a radio signal to a radio receiver at a second repeater which is physically adjacent the controlled device(s). The radio receiver generates a second electrical signal representative of the received radio signal and this second electrical signal activates an infrared transmitter which transmits an infrared signal to the controlled device(s).

Abstract: A cover with novel hold down means is provided for a vehicle having an open bed, such as a pickup truck, for covering and enclosing the vehicle bed. The cover is constructed of a rigid or semirigid material and is hinged to one sidewall of the vehicle bed so that the cover can pivot upwardly from the other sidewall of the vehicle bed to permit access into the interior of the bed. In addition the novel hold down means comprises an elongated member which threadably engages a V-shaped member and both of which are inserted into a stake hole on the vehicle bed. Rotation of the member moves the V-shaped member upwardly to clampingly engage the interior of the vehicle sidewall.
