  • Patent number: 5318862
    Abstract: A bifunctional gas diffusion electrode used in an electrochemical energy cell wherein a multi-ply composite layer containing an embedded metal screen current collector provides electrical power via the reduction of oxygen from air in the presence of an electrolyte and a catalyst. The electrode stores electrical power via the evolution of oxygen in the presence of an electrolyte and another catalyst. More than one composite layer may be used. Each ply of any particular composite layer is made of carbon-containing material of varying wettability and a fluorocarbon material. Each hydrophobic central ply contain a metal screen current collector. These central plies are prepared in a way to foster fissuring throughout the ply. Such fissuring, along with a hydrophilic impregnate forced into these fissures, permits controlled electrolyte penetration of the hydrophobic ply.

  • Patent number: 5307427
    Abstract: A device, system and method of image processing and compression are preferably used with second generation infrared (IR) detector arrays where the pixel size is less than the optical blur of the system. Raw input pixels are compressed such that output pixels are more closely matched to the optical blur of the system. Further, the number of output pixels are compressed from a greater number of input pixels, based upon a selected input-to-output compression ratio. The ratio is not constrained to be of an integer value. The compression takes place using a plurality of neighborhood processors, each corresponding to a different output pixel type. Each neighborhood processor contains a plurality of different predetermined weighed fractions of input pixel data and are used to produce compressed output pixel data, based upon the selected input-to-output compression ratio and the output pixel type, for real-time processing.

  • Patent number: 5305288
    Abstract: A variable reluctance acoustic projector includes a piston structure that provides rigid retention and precise alignment of electromagnetic cores within the projector housing. The piston structure provides a pair of metallic piston blocks having cavities in which the electromagnetic cores are mounted. The piston blocks rigidly retain the electromagnetic cores within the cavities by compressive loading, improving the structural reliability of the device. In addition, the piston blocks enable precise alignment and orientation of the pole faces of opposing electromagnetic cores parallel to one another. Flexure ribs formed in the piston blocks increase the compliance of the blocks to substantially confine motion of the piston blocks to translation along a single axis of actuation during excitation of the electromagnetic cores.

  • Patent number: 5291155
    Abstract: A microwave buffer for use between transmitter modules and an impedance combiner. The buffer is comprised of a plurality of input segments, a plurality of output segments and an elongated transmission segment connecting the input segments to the output segments. The geometry of the buffer along with bridges located proximate to the transmitter modules eliminate the destructive effects of reflected waves set up by an unbalanced impedance combiner when one of the transmission modules becomes inoperative. The hourglass shape of the buffer causes the phases of the signals from each transmission module to be equal from any transmission port to any output. The bridges force the sum of the mutual couplings to be low in amplitude on any transmission module.

  • Patent number: 5274235
    Abstract: A totally integrated imaging system has a housing including imaging optics, a scanning mirror and a curved detector array. The imaging optics constitute a meniscus lens and a spherical focusing mirror. The scanning mirror scans the image, and the spherical mirror focuses the scanned image onto the detector array. The meniscus lens advantageously corrects aberrations. A detector support provides access, if desired, for cryogenic cooling of the detector, and individual cold shielding of the detector elements is made possible by the telecentricity of the optics. Processing electronics, at least a portion of which may also be disposed on the detector support, process the detector signals to display an image. The integrated structure advantageously eliminates any need for separate scanner, imager, and electronics modules and the scanning optical system obtains highly desirable image quality over a wide field of view.

  • Patent number: 5265421
    Abstract: An hydraulic liquid system wherein a pump moves liquid from one location to another such as in supplying one or more loads in an underwater environment. The system includes two hydro-pneumatic chambers utilized such that one is filled by liquid from the pump while the other supplies the load, and as one hydro-pneumatic chamber empties, valves reconfigure the system such that the hydro-pneumatic chamber reverse roles. Each hydro-pneumatic chamber includes a liquid side and a gas side separated by a movable barrier with the gas sides of the hydro-pneumatic chambers being connected to one another thereby providing a large acoustic transmission drop across a liquid-gas boundary and subsequent gas-liquid boundary to interrupt the liquid noise path from the pump to the load.

  • Patent number: 5266925
    Abstract: An electronic identification tag interrogation method is provided in which a portal transmits an interrogation signal which is received by an electronic identification tag within its field of range. The interrogation signal includes an address which requests a response from every tag having an address greater than or equal to the address of the signal. If more than one reply is received by the portal, the interrogation address is bisected and the interrogation signal is retransmitted. The interrogation address is successively bisected until a single response is isolated. When a single response is isolated, communication is directed between the portal and the identification tag and the interrogation system is reset to isolate and identify any remaining tags.
