Patent number: 7242007Abstract: A sensor having a light detector with a small gap between the cathode and anode to enable a high pressure cavity resulting in a long lifetime of the detector due to insignificant sputtering from the cathode and subsequent minimal burying of the noble gas in the cavity. The detector may be made with MEMS technology and its techniques. The sensor may contain an array of light detectors. Some of the detectors may be UV detectors.Type: GrantFiled: October 1, 2004Date of Patent: July 10, 2007Assignee: Honeywell International Inc.Inventor: Barrett E. Cole

Patent number: 7230432Abstract: A sensor having a nanotube grown on and supported by thermal bimorph structures. The nanotube rests on a heat sink during sensing gas or a liquid and is moved from the heat sink when the nanotube is heated to desorb gas or liquid from it. The heatsink may function as a gate along with the bimorph structures as the other terminals of a transistor. Current-voltage and current-gate voltage characteristics may be obtained of the nanotube as a device like a transistor. These characteristics may provide information on a gas or liquid absorbed by the nanotube.Type: GrantFiled: June 14, 2005Date of Patent: June 12, 2007Assignee: Honeywell International Inc.Inventors: Barrett E.

Patent number: 7170059Abstract: A thermal sensor structure having one level for an infrared detecting pixel including the sensor associated electronics. The electronics displace a small area thereby having little effect on the fill area of the pixel relative to a level having no pixel electronics. That level has thermally isolation for the substrate through the limited structural attachment to the substrate because of the access vias to the silicon. It has additional isolation because of a pit of removed silicon from the substrate below that one level. The thermal sensor may have an array with a large number of pixels having the one level for the pixels and electronics structure.Type: GrantFiled: October 3, 2003Date of Patent: January 30, 2007Inventors: Roland A. Wood, Robert E. Higashi, Barrett E. Cole

Patent number: 7145143Abstract: A tunable bolometer device for detecting infrared light (IR) from a target at specific frequencies and in a broadband mode. The device may have an array of pixels of which each is controllable to be sensitive to a particular wavelength of light that is selected and detected. The detection of particular frequencies on a pixel level may result in spectral analysis of the target. Further, each pixel of the bolometer via an associated etalon may be tuned to detect a different frequency of IR or be switched to broadband detection of IR. The device may be packaged in an integrated vacuum package where the etalon array becomes the topcap which is bonded to the wafer containing the bolometer array.Type: GrantFiled: December 31, 2003Date of Patent: December 5, 2006Assignee: Honeywell International Inc.Inventors: Roland A.

Patent number: 7145165Abstract: A sensitive fluid sensor for detecting fluids and particularly trace fluids. The sensor may be adjustable for detecting fluids of various absorption lines. To effect such adjustment, a tunable laser may be used. The laser may be an edge emitting diode, a VCSEL or other tunable source. The detection apparatus of the sensor may incorporate a sample cell through which a laser light may go through. The sample cell may comprise a tunable ring-down cavity. The ring-down cavity may be a ring laser cavity like that of a ring laser gyroscope. There may be a photo detector proximate to the ring down cavity connected to a processor.Type: GrantFiled: September 28, 2004Date of Patent: December 5, 2006Assignee: Honeywell International Inc.Inventors: James A.

Patent number: 7057402Abstract: Carbon nanotubes are formed on projections on a substrate. A metal, such as nickel is deposited on the substrate with optional platforms, and heated to form the projections. Carbon nanotubes are formed from the projections by heating in an ethylene, methane or CO atmosphere. A heat sensor is also formed proximate the carbon nanotubes. When exposed to IR radiation, the heat sensor detects changes in temperature representative of the IR radiation. In a gas sensor, a thermally isolated area, such as a pixel is formed on a substrate with an integrated heater. A pair of conductors each have a portion adjacent a portion of the other conductor with projections formed on the adjacent portions of the conductors. Multiple carbon nanotubes are formed between the conductors from one projection to another. IV characteristics of the nanotubes are measured between the conductors in the presence of a gas to be detected.Type: GrantFiled: January 10, 2005Date of Patent: June 6, 2006Assignee: Honeywell International Inc.Inventors: Barrett E.

Patent number: 7048384Abstract: A projection system for presenting infrared scenes having biological and chemical agents, simulants and objects such as battlefield items. The generated scenes are primarily for the evaluation of infrared sensors, cameras and stand-off detectors. The system may have two or more projectors that combine various scenes into one scene having components with modified or imposed spectra signatures. Also, the system may generate a dynamic series of scenes that show synthetic scenarios of moving objects, agent clouds, non-toxic simulants and other items.Type: GrantFiled: January 24, 2003Date of Patent: May 23, 2006Assignee: Honeywell International Inc.Inventors: Barrett E.

Publication number: 20040223882Abstract: A micro plasma sensor system having a glow discharge gap. A fluid to be sensed may be brought into the vicinity of the discharge at the gap. Emission light from the discharge may be coupled to an optical spectrum analyzer for determining properties of the fluid. The coupling may include a window and particulate-matter-sensing electrodes proximate to the discharge gap. Window cleanliness and electrode electrical isolation may be maintained by the discharge. The optical analyzer may have individual bandpass filters for two or more optical channels to optical detectors, a Fabry-Perot filter in front of a set of optical detectors, or a grating or prism which disperses emission light at various angles according to wavelength to an array of light detectors. The optical detectors may output electrical signals to be processed.Type: ApplicationFiled: December 31, 2003Publication date: November 11, 2004Inventors: Ulrich Bonne, Michael L. Rhodes, Barrett E.

Patent number: 6816636Abstract: A tunable filter having a top mirror, a bottom mirror, and one or more intervening layers. The one or more intervening layers preferably have a refractive index that changes with temperature. By heating the one or more intervening layers, the wavelength that is selected by the optical filter can be controlled. The one or more intervening layers are preferably heated by passing current through the one or more intervening layers, or by passing current through a separate resistive layer that is thermally coupled to the one or more intervening layers. Such a filter can provide a high degree of wavelength selectivity in a robust and stable manner.Type: GrantFiled: September 12, 2001Date of Patent: November 9, 2004Assignee: Honeywell International Inc.Inventors: Barrett E.
