Patent number: 6920876Abstract: The present invention is directed to a nitric gas dispenser for mammals on the run. The dispenser has a housing that contains a valve mechanism. The valve mechanism is interconnected between a nitric gas dispersal component that provides nitric gas at a desired pressure and a gas delivery system that provides the nitric gas at the desired pressure to the mammal. The valve mechanism controls the flow of the nitric gas between the nitric gas dispersal component and the gas delivery system. The dispenser also has a pressure sensor that is positioned along the gas delivery system and determines when the mammal is taking a breadth. If the pressure sensor determines the mammal is taking a breadth, the pressure sensor transmits a breadth signal to a microprocessor. The microprocessor then determines if the mammal is within a prescribed time frame for the mammal to be administered nitric gas.Type: GrantFiled: December 10, 2002Date of Patent: July 26, 2005Assignee: Pulmonox Technologies CorporationInventors: Christopher Miller, Bryan Perry, Robert E.

Patent number: 6920290Abstract: An array of diffraction grating coupled infrared photodetectors is coupled to corresponding high-speed amplifiers for creating a multiple channel high speed receiver for an optical communication system. Each photodetector includes a three-dimensional diffractive resonant optical cavity formed by a diffraction grating that resonates over a narrow range of wavelengths. By creating different resonant optical cavities, the receiver detects each optical channel individually, thereby simplifying receiver design. The receiver finds ready application in systems based upon high power CO2 lasers and semiconductor lasers such as quantum cascade lasers allowing extremely long line of sight communication, such as between satellites. Other applications include ship to ship or ground to missile communications. These applications will benefit from increased jamming resistance and security.Type: GrantFiled: July 11, 2001Date of Patent: July 19, 2005Assignee: Lockheed Martin CorporationInventor: Pradip Mitra
