Patent number: 8335083Abstract: An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.Type: GrantFiled: October 21, 2010Date of Patent: December 18, 2012Assignee: Honeywell International Inc.Inventors: Wei Yang, Steven J.

Patent number: 8294008Abstract: 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: May 16, 2006Date of Patent: October 23, 2012Assignee: Honeywell International Inc.Inventors: Barrett E.

Patent number: 8241919Abstract: A method includes acquiring a chemical sample and modulating the chemical sample at a frequency greater than a drift frequency of a sensor. The method also includes determining at least one of a presence and a concentration of the analyte within the modulated chemical sample using the sensor. Modulating the chemical sample could include alternately absorbing at least some of the analyte into a sorbent material and releasing at least some of the analyte from the sorbent material. Modulating the chemical sample could also include heating the sorbent material, absorbing part of the analyte into the sorbent material, and passing a remaining portion of the analyte into the sensor. Modulating the chemical sample could further include stopping the heating of the sorbent material, releasing the part of the analyte from the sorbent material, and passing the sample with the released part of the analyte into the sensor.Type: GrantFiled: October 28, 2008Date of Patent: August 14, 2012Assignee: Honeywell International Inc.Inventors: Adam Dewey McBrady, J.

Patent number: 7197949Abstract: A sampling system for detecting an analyte, comprising a diaphragm pump, a buffer chamber, a sensor head and intake port. The pump includes a chamber for receiving fluids via first and second ports. A buffer chamber is located at the second port for holding a quantity of air, and a sensor head is adapted to identify the presence of a desired analyte and produce a signal in response to the quantity identified. Preferably the diaphragm pump has a volume of gas per stroke capacity slightly larger than the volume of the sensor head such that the pump chamber has a greater volume than the buffer chamber and the buffer chamber has about the same volume as the sensor head. A sensor intake port intakes a sample potentially containing the analyte for contact with the sensor head upon operation of the diaphragm pump and out of the sensor head by jet-action caused by rapid movement of the diaphragm pump. A filter may be used for filtering air drawn through the pump chamber.Type: GrantFiled: April 2, 2002Date of Patent: April 3, 2007Assignee: Honeywell International Inc.Inventors: J.

Publication number: 20060161364Abstract: A control system coupled to a pressure sensor calibrates the pressure sensor. The control system may measure a plurality of capacitance values at a plurality of corresponding applied voltages to compare the values with a first calibration mechanism generated by sample pressure sensors in a comparison. A final calibration mechanism may be generated by adjusting the first calibration mechanism in response to the comparison. The unknown differential pressure may be applied to a diaphragm of the pressure sensor. A capacitance value at the unknown differential pressure may then be measured. Using the final calibration mechanism, the differential pressure at the measured capacitance value may be retrieved.Type: ApplicationFiled: December 30, 2004Publication date: July 20, 2006Inventors: Tzu-Yu Wang, Cleopatra Cabuz, Eugen Cabuz, Stephen Shiffer, David Zook
