  • Patent number: 7487067
    Abstract: Provided is a method and system for signal-driven recovery of a digital pulse stream. The method includes receiving initial parameters including the base characteristics of a pulse signal, the characteristics including the maximum pulse interval. An incoming analog signal is converted to a digital signal and sampled a predetermined number of times at intervals greater than the maximum pulse interval to record a set of minimum signal values and a set of maximum signal values. Each set is averaged to provide an average minimum value and an average maximum value. Based on these values at least one threshold value is then determined, and the digital pulse stream is identified based on the threshold values. The method is repetitive, continually re-determining the threshold values so as to adapt to changes in the incoming signal. A system for performing the method is also provided.

  • Patent number: 7456746
    Abstract: A phase shifting diode detector system for an RFID reader. Quarter-wave delay circuitry is coupled between a forward transmitted signal of the RFID reader applied at a first end of the delay circuitry, and a reflected signal returning from an RFID tag applied at a second end of the delay circuitry. The system includes a pair of diode detector bridges, each comprising a series-coupled diode pair configured such that diode polarities in each bridge are reversed relative to the output thereof, to produce opposite rectified signal output polarities. An input to each of the bridges is capacitively coupled, from the junction between each said diode pair, to a respective opposite end of the delay circuitry.

One method forms a lens with wavefront coding. The method includes positioning a lens in a mold; and curing material onto a surface of the lens to form an aspheric surface of the lens with wavefront coding.

  • Patent number: 7450745
    Abstract: An imaging system for reducing aberrations from an intervening medium, and an associated method of use are provided. The system may be an optical or task-based optical imaging system including optics, such as a phase mask, for imaging a wavefront of the system to an intermediate image and modifying phase of the wavefront such that an optical transfer function of the system is substantially invariant to focus-related aberrations from the medium. A detector detects the intermediate image, which is further processed by a decoder, removing phase effects from the optics and forming a final image substantially clear of the aberrations. Other systems may employ an encoder that codes wavefronts of acoustical waves propagating through a medium to make the wavefronts substantially invariant to acoustical aberrations from the medium. Imaging and decoding of the wavefronts reverse effects of the wavefront coding and produce sounds substantially free of the aberrations.

  • Patent number: 7446601
    Abstract: RF field is sensed to produce an incoming voltage that drives a microarray of electron guns in a sweep pattern towards a detector array. The electron guns emit a beam current that may amplify the incoming voltage signal, and the detector material may be selected to amplify the beam current at the detector, for example, by avalanche and/or cascade in a Schottky material, to provide a low current, high gain amplification. The microarrays may be arranged in various combinations to produce successive amplifications, frequency multipliers, transmit-receive amplifiers, crossbar switches, mixers, beamformers, and selective polarization devices, among other such devices.

  • Patent number: 7442313
    Abstract: Remediation for groundwater, soil, sediment bodies, bodies of water, tanks, pipes, and their surrounding areas are described. Remediation includes treating a site contaminated with toxic organic compounds by assessing for the presence or absence of suitable ozonphilic bacteria at the site and introducing ozone to the site. The ozonphilic bacteria are introduced to the site if the ozonphilic bacteria are not present or not present in sufficient quantities in the site. Ozone is introduced to the site in an amount sufficient to stimulate growth of the suitable ozonphilic bacteria. Other oxidants can also be used.
