Abstract: A network (20) employs a wireless network topology (30), a wireless network manager (40). Network (20) further employs a wireless device (70) and wireless device manager (80) pairing and/or a wireless system (90) and a wireless system manager (100) pairing. Managers (40, 80) cooperatively control an operating profile and monitor an operational status of the device (70). Managers (40, 100) cooperatively control an operating profile and monitor an operational status of system (90). Manager (40) can be installed on a computer (150, 170) and wirelessly communicate within network (20) via a wireless control device (160, 180) employing a port connector (161, 181) that can be plugged into a port (151, 171) of the computer (150, 170). Device (70) or system (90) can implement a digital ballast (120) that determines an average power consumption of the digital ballast (120) drawn by a power interface (121) of digital ballast (120).

Abstract: An infrared signal interface enables an infrared detector module to communicate with the door edge signal input of a garage door operator. The infrared signal interface has a power supply for driving the pulsed infrared detector. Pulsed signals are received by a missing pulse detector that controls a relay. The relay may be coupled to the door edge signal of the garage door operator.

Abstract: A range extender module for extending the range capability of a barrier control system comprising a low voltage AC control unit which receives low voltage AC control signals conveyed by wires to input terminals thereof from a plurality of remotely located switches and responds to such AC control signals by controlling the barrier. The controlled barrier may be, for example, a garage door or a driveway gate. The range extender module is inserted into the wires between the low voltage AC control unit and the remote switches and includes a source of DC voltage, which is used to energize the formerly AC energized switches and responds to DC input signals created by operator interaction with the switches by selectively gating low voltage AC control signals to appropriate input terminals of the low voltage AC control unit for controlling the barrier.

Abstract: Electrical apparatus including a housing enclosing a printed circuit board mounting a plurality of electrical components. The printed circuit board is detachably mounted on a pivotal support which permits rotation of the circuit board between various positions in the access opening to the housing. The support is a one piece plastic member which frictionally receives the printed circuit board in an elongated slot.
