Patent number: 7869718Abstract: A wireless, automatic door obstruction detection system for protecting a motorized door or gate by signaling various hazardous conditions and reacting to said conditions by signaling control means. The invention utilizes wireless infrared emitter, receiver and controller apparatus. Infrared pulse timing data is sent as pulse repetition rate changes depending upon battery condition. In a preferred embodiment of the invention, the photoelectric transmitter emits timed pulse groups to present control information differentiating between a good battery and a low battery condition in the wireless transmitter. A wireless photoelectric transmitter extends the time period between pulse groups to indicate a low battery condition. A low battery condition signaling thereby presents a low power drain condition allowing for an extended period of low battery condition signaling.Type: GrantFiled: November 29, 2007Date of Patent: January 11, 2011Assignee: Miller Edge, Inc.Inventors: Vinay Sao, Krishnaraj N.

Patent number: 7123144Abstract: An automatic door opening system utilizing wireless links to communicate from hazard or obstruction sensors to a controller to react to such conditions. The present invention allows the use of hazard, fault or obstruction switching devices which themselves utilize internal continuity monitoring in a wireless environment. Compressible hazard switch sensors which utilize internal, continuous conducting elements are continually monitored for breaks in such elements through continuity checks. A signal is generated from the wireless transmitter during door operation to indicate to the system that the link between the wireless transmitter and a wireless receiver is fully functioning at all times. The system can determine if an actual obstruction hazard is detected or if there is a loss of communications between the wireless transmitter and receiver link in the disclosed system while also allowing for wireless continuity checking between sensor switches utilized.Type: GrantFiled: April 23, 2004Date of Patent: October 17, 2006Assignee: Miller Edge, Inc.Inventors: Michael Anderson, Timothy Castello, Gary Leigh, Bearge Miller

Patent number: 6920717Abstract: A non-contact sensor system controls movement of a door moving in a first direction. The system includes a rigid mounting bracket attached to a leading edge of the door, a transmitter extending a distance beyond a leading edge of the door at a first door end for transmitting a signal toward a second door end. The transmitter is attached to the rigid mounting bracket by a first moveable member configured to engage a surface when the door closes and moving to a retracted position. The sensor system further includes a receiver extending a distance beyond the leading edge of the door at the second door end in alignment with the transmitter for detecting the signal and for generating an output signal. The receiver is attached to the rigid mounting bracket by a second moveable member configured to engage the surface when the door closes and moving to the retracted position.Type: GrantFiled: November 4, 2003Date of Patent: July 26, 2005Assignee: Miller Edge, Inc.Inventors: Bearge D.

Patent number: 6683296Abstract: A sensing edge for controlling movement of a door by actuation of a device upon an external force being applied to the sensing edge includes an elongated generally flexible tubular sheath secured to the leading edge of the door. The sheath has a longitudinal axis generally parallel to a leading edge of the door and includes an elongated hollow cavity extending generally parallel to the longitudinal axis, a first open end and a second open end. The sensor system includes a transmitter near the first end of the sheath for transmitting a signal through the cavity toward the second end of the sheath. The sensor system also includes a receiver near the second end of the sheath in alignment with the transmitter for detecting a signal at the second end and for generating an output signal upon detection of an absence of the signal when the passage of the signal through the cavity is blocked.Type: GrantFiled: September 13, 2001Date of Patent: January 27, 2004Assignee: Miller Edge, Inc.Inventors: Bearge D.

Patent number: 6571512Abstract: A sensing edge for actuating a device to cause a closing door to stop closing upon a force being applied to the sensing edge. The door has a sensing edge surface, which includes an elongated sheath positioned adjacent to the leading edge surface of the door and is compressible upon application of an external force. Within the sheath is a cavity where a sensor is positioned which is responsive to an external force applied to the sheath. A closure is positioned proximate an end of the sheath. The closure has a channel in an outer surface which extends the width of the closure. The closure further includes a passageway therethrough extending from the cavity to the channel. At least one electrical conductor, which extends through the passageway and partially through the channel to one of the front and rear sides, is in electrical communication with the sensor.Type: GrantFiled: April 24, 2002Date of Patent: June 3, 2003Assignee: Miller Edge, Inc.Inventors: Bearge D.

Patent number: 5759427Abstract: A technique for chemically planarizing an exposed surface of metal on a substrate to a pre-determined thickness is provided. The substrate has an exposed metal surface such as copper circuitry on a dielectric substrate which is to be planarized. Typically, this will be circuitization extending above a photoresist layer. A planarizing head is rotated against the substrate, with the planarizing head in contact with the metal surface on the substrate. A chemical etchant, essentially free of abrasive material, is continuously supplied to the interface between the metal surface and the planarizing head. The planarizing continues until a predetermined thickness of the metal has been reached. In circuit board manufacturing, this will form a surface co-planar with the photoresist. In some instances where significant height reduction is required, thus requiring significant metal removal, several passes of the substrate may be required or a device with multiple heads may be used.Type: GrantFiled: August 28, 1996Date of Patent: June 2, 1998Assignee: International Business Machines CorporationInventors: Edward Cibulsky, Gerald Andrew Kiballa, Voya Rista Markovich, Gary Leigh Newman, John Francis Prikazsky, Michael Wozniak
