  • Infrared radiation sources, sensors and source combinations, and methods of manufacture
    Patent number: 7968848
    Abstract: A blackbody radiation device (110) includes a planar filament emission element (102) and a planar detector (104) for respectively producing and detecting radiation having width dl/l less than about 0.1 to test a sample gas, where l is the wavelength of the radiation; a reflector (108); a window (W); an electrical control (118); and a data output element (116).
    Type: Grant
    Filed: March 30, 2009
    Date of Patent: June 28, 2011
    Assignee: Nomadics, Inc.
    Inventors: Edward A. Johnson, James T. Daly, John S. Wollam, W. Andrew Bodkin

  • Electrical power source
    Patent number: 7157802
    Abstract: An electrical power source is described. The electrical power source derives input power from a compressed gas which is fed into a transducer, generating electrical power. The compressed gas may be delivered to the unit by several means including manual pumps, thermal, chemical, or ammunition based sources, or connection to pressurized canisters. Optional power converting and feedback circuits and pneumatic valves serve to convert the raw output power into useful AC and DC output voltages, and to match the rate of power delivery to the applied electrical load.

  • Railway car retarder
    Patent number: 5388525
    Abstract: An improved railway car retarder, fitted with fluid power cylinders, such as hydraulic or pneumatic cylinders. The cylinders function to temporarily release the force of retarder friction rails on train car wheels. The retardation function is still carried out by conventional spring assemblies and the functional integrity of existing retarders is not disrupted.
