Patent number: 10386226Abstract: An optical safety beam method and system. A transmitter periodically sends bursts of light pulses with varying strengths. The receiver analyzes the received light pulses to automatically adjust its sensitivity and to detect when the light path is partially obstructed even when there are stray light pulse reflections that reach the receiver.Type: GrantFiled: May 18, 2018Date of Patent: August 20, 2019Assignee: Mars International, Inc.Inventors: Geoffrey Engelstein, David Salgueiro, Mohamed Abdelhafez, Ralph Giffone, Andrew Lindsay

Patent number: 7822349Abstract: In an IR communication network, a method is described to optimize channel performance in the presence of strong and varying IR interference. The method controls of the channel gain based on quantitative measurement of the channel noise.Type: GrantFiled: July 30, 2003Date of Patent: October 26, 2010Assignee: Inncom International, Inc.Inventors: Philipp Roosli, Ralph Giffone, Hazrat Shah

Patent number: 6995670Abstract: A capacitive sensor system for controlling operation of a device in response to a rate of change in capacitance due to motion of a proximate object includes at least two sense electrodes disposed on a surface and a phase locked loop, including a voltage controlled oscillator and a phase/frequency comparator, connected between the sense electrodes and an RC network for providing an operating frequency to the sense electrodes. A circuit loop, including a reference oscillator, provides a fixed frequency reference for the phase locked loop to follow and a phase delay circuit connected between the phase/frequency comparator and the voltage controlled oscillator causes the voltage controlled oscillator to run ahead of the reference oscillator. A trigger circuit provides a control output in response to a change in phase shift between the fixed frequency and the operating frequency.Type: GrantFiled: December 5, 2003Date of Patent: February 7, 2006Assignee: Gerenraich Family TrustInventors: David Wadlow, Frank Scholten, Ralph Giffone, Kenneth Gerenraich

Patent number: 5625980Abstract: An automatic door opening safety system particularly for use with garage doors is provided. The garage door includes a leading edge that moves from the open position, where the leading edge defines the top of the opening and a closed position, where the leading edge contacts the ground. A controller is provided for controlling movement of the door. An activation member provides an input to the controller to initiate movement of the door. A non-contact detector detects whether an obstruction is in the path of the door. The non-contact detector is positioned in front of the leading edge of the door, such that obstructions are detected at a predetermined distance in front of the leading edge of said door.Type: GrantFiled: July 26, 1994Date of Patent: May 6, 1997Assignee: RMT AssociatesInventors: Oren Teich, Vijay Tandon, Rudor Teich, Ralph Giffone

Patent number: 4827247Abstract: A modular transceiver head including cooperative cover and base members operable as a transmitter or as a receiver of infrared energy. The cover member includes a window defining a comparatively wide field of view in azimuth and in elevation. An optical train including a gimbaled specular member that is mounted to the base member readily allows both rough and fine adjustment of the pointing direction of the specular member anywhere within the field of view of the cover member window. A controller including a processor is coupled to a transceiver head pair respectively operative as a transmitter and as a receiver of infrared energy to controllably project a beam of infrared energy therebetween through a protected region. The controller is operative to de-sensitize the beam against potential electrically interferring effects present along the beam path. The controller is periodically operative in a self-test mode to reduce the intensity of the projected-beam to simulate a smoke condition.Type: GrantFiled: April 13, 1987Date of Patent: May 2, 1989Assignee: ADT, Inc.Inventor: Ralph A. Giffone

The controller is operative to de-sensitize the beam against potential electrically interferring effects present along the beam path. Plural alarm thresholds are operator selectable to provide enhanced confidence detection, and particularized signal indications are provided to readily and quickly identify possible alarm and trouble conditions.Type: GrantFiled: September 1, 1988Date of Patent: April 18, 1989Assignee: ADT, Inc.Inventors: Aaron A.
