Patent number: 7947901Abstract: A sealed device with integral weatherproof cover includes a device integral with a weatherproof cover to prevent the introduction of moisture into the device. A portion of the device is positioned within the weatherproof cover housing. The device includes wires extending out through one or more openings along or near the back of the device. The openings are environmentally sealed around the wires to prevent moisture from passing therethrough. The weatherproof cover housing includes a pair of openings. A portion of the device is positioned next to, and sometimes through, one of the openings. A door is coupled to the weatherproof cover housing and positioned adjacent the other opening. The door can be moved about an axis along an edge of the weatherproof cover housing such that the door can be adjusted between an open position and a closed position about the second opening.Type: GrantFiled: September 30, 2008Date of Patent: May 24, 2011Assignee: Cooper Technologies CompanyInventor: Howard S.

Patent number: 6949995Abstract: A ground fault circuit interrupter (GFCI) for opening a circuit when a ground fault has been detected in an attached circuit includes a current path structure containing no more than one splice and no more than one pair of contacts. A cantilevered movable contact arm and an activation device that moves in a linear fashion can be provided to open the current path structure when a ground fault is detected by the GFCI. In addition, the GFCI can include a transformer boat and solenoid bobbin that are snap fit onto a circuit board and located adjacent each other to provide rigidity to the circuit board and GFCI. The GFCI can be tested by a test switch that includes an integral cantilevered extension from an electrical terminal disposed over a resistor such that the cantilevered extension can be bent by a test button to contact a lead of the resistor and simulate a ground fault condition for the GFCI.Type: GrantFiled: January 13, 2003Date of Patent: September 27, 2005Assignee: Cooper Wiring Devices, Inc.Inventors: Howard S.

Patent number: 6829124Abstract: A fault circuit interrupter with functionality for reset can include a relay that trips a first circuit when a ground fault or other error is detected in the first circuit. The relay can be a bistable type of relay that is caused to change state by the detection of a ground fault (or other error) in the first circuit. To reset the fault circuit interrupter after it has tripped, a reset mechanism can include means for simulating a ground fault (or other error). A signal can be sent to the relay when a simulated ground fault (or other simulated fault) is output, such that the signal causes the relay to change state to re-close the first circuit after the trip. Accordingly, the interrupter is automatically tested for functionality when it is reset. Moreover, the fault circuit interrupter cannot be reset if the circuitry of the fault circuit interrupter is not operational.Type: GrantFiled: June 8, 2001Date of Patent: December 7, 2004Assignee: Cooper Wiring Devices, Inc.Inventors: Howard S. Leopold, Gunter A. Gallas

Patent number: 6815625Abstract: A dimmer control system has a communication control loop that connects a master unit in series with a plurality of remote units, and it is superimposed in series on the dimmer load line so as to allow two-way communication between the master unit and remote units without affecting the operation of the load. Communications from the master to the remote units are encoded in loop current fluctuations, whereas communications from any remote to the master unit are encoded in loop voltage fluctuations. The master unit has a switched power supply, for use during normal LOAD ON operation, in tandem with a capacitive power supply, for use during LOAD OFF operation of the control units so as to minimize hum. The master unit power supply circuit provides an output rail voltage comprised of a reference voltage for the load superimposed with a control loop voltage for the voltage drop across the series-connected remote units.Type: GrantFiled: November 7, 2003Date of Patent: November 9, 2004Assignee: Cooper Wiring Devices, Inc.Inventors: Howard S. Leopold, Lenny M. Novikov, Erik J. Gouhl
