Patent number: 6839371Abstract: A semiconductor laser device includes a substrate having on a surface thereof a semiconductor diode laser portion and a linear amplifier portion. Each of the laser portion and amplifier portion has a waveguide layer with the waveguide layers being in alignment. The laser portion is of a structure which permits it to generate radiation and emit the radiation from one end. The amplifier has an end that receives the radiation from the laser portion, and another end with emits the radiation after the radiation is amplified. The device emits FM radiation but not IM radiation.Type: GrantFiled: May 1, 2000Date of Patent: January 4, 2005Assignee: Sarnoff CorporationInventors: Ramon Ubaldo Martinelli, Alan Richard Sugg, Raymond Joseph Menna

Patent number: 6535275Abstract: A three-dimensional imaging range finder is disclosed using a transmitted pulse reflected from a target. The range finder includes a pixel sensor for receiving light from the target and the reflected pulse. A global counter is provided for determining a time-of-flight value of the transmitted pulse by providing accurate count data to pixel memories. A processing circuit, which is coupled to the pixel sensor and the global counter, extracts the reflected pulse received by the pixel sensor, and stores the time-of-flight value upon extracting the reflected pulse. The pixel sensor provides a luminance signal and the processing circuit includes a high pass filter to extract the reflected pulse from the luminance signal.Type: GrantFiled: January 30, 2001Date of Patent: March 18, 2003Assignee: Dialog Semiconductor GmbHInventors: Nathaniel Joseph McCaffrey, Robert James Andreas, Peter Alan Levine, Ramon Ubaldo Martinelli

Patent number: 6249001Abstract: An infrared imager includes an array of capacitance sensors that operate at room temperature. Each infrared capacitance sensor includes a deflectable first plate which expands due to absorbed thermal radiation relative to a non-deflectable second plate. In one embodiment each infrared capacitance sensor is composed of a bi-material strip which changes the position of one plate of a sensing capacitor in response to temperature changes due to absorbed incident thermal radiation. The bi-material strip is composed of two materials with a large difference in thermal expansion coefficients.Type: GrantFiled: April 8, 1999Date of Patent: June 19, 2001Assignee: Sarnoff CorporationInventors: Donald Jon Sauer, Ramon Ubaldo Martinelli, Robert Amantea, Peter Alan Levine

Patent number: 6133520Abstract: A thermophotovoltaic cell and diode photodetector having improved open circuit voltage and high internal efficiency includes a semiconductor body having regions of n-type conductivity and p-type conductivity adjacent each other to form a p-n junction therebetween. The p-type region is of a material having a band gap which will absorb black-body radiation and the n-type region is of a material having a wider band gap than that of the p-type region. This forms a heterojunction between the two regions. The region of n-type region has a doping level which is an order of magnitude less than the doping level in the p-type region. This structure forms a cell having a space charge region in the n-type region.Type: GrantFiled: November 12, 1998Date of Patent: October 17, 2000Assignee: Sarnoff CorporationInventors: Dmitri Zalmanovich Garbuzov, Victor Borisovich Khalfin, Ramon Ubaldo Martinelli, Hao Lee, Nancy Ann Morris, John Charles Connolly
