  • Patent number: 7948428
    Abstract: A millimeter wave imaging system. The system includes one or more millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view and millimeter wave amplifier components for amplifying the millimeter wave radiation collected by each antenna. The system includes a beam-former that separates the amplified radiation to produce frequency dependent signals corresponding to the frequency dependent beams. The beam-former includes delay lines, a millimeter wave lens, and an array of millimeter wave power detectors for detecting the power in each frequency dependent beam. A sampling circuit reads out the frequency dependent signals to produce a one-dimensional image of the antenna field of view. A two dimensional image of a target may be obtained by moving the target (or having the target move) across the field of view of the scanning antenna or by moving the antenna in order to scan its line of focus over the target.

  • Patent number: 7942720
    Abstract: A child's stuffed teddy bear embodiment is made with arms that are animated by an internal electronically-controlled electric motor. The paws at the ends of arms are normally located initially so as to cover the bear's eyes, with the head inclined slightly and the eyes downcast. When a child approaches the bear within a predetermined distance, a built-in proximity sensor initiates the bear's built-in animation system to move the arms so as to remove the hands from the eyes, incline the head upwardly and immediately speak a phrase such as “peek-a-boo” generated by a built-in speech synthesizer, audio amplifier and loudspeaker. Then the cycle is completed by returning to the initial condition: the end of the paws again covering the eyes and the head inclining downwardly.

  • Patent number: 7935882
    Abstract: A self-powered food heater. The food heater includes a burner with an electric fuel pump and an electric blower, a fire box, a water tank and electronic controls. The food heater also includes a set of thermoelectric modules compressed against a heat transfer surface of the tank. Hot exhaust leaving the burner enters the fire box. Some of the heat from the fire box passes through the thermoelectric modules generating sufficient electric power to power the fuel pump and the blower. Water in the tank is heated to its boiling temperature. Heat from the boiling water heats food also contained in the tank. In a preferred embodiment special compression frames provide substantially uniform compression, within desired ranges, of the modules between a portion of the heat transfer surface of the tank and a module cover plate.

  • Patent number: 7906826
    Abstract: A CMOS image sensor with a many million pixel count. Applicants have developed techniques for combining its continuous layer photodiode CMOS sensor technology with CMOS integrated circuit lithography stitching techniques to provide digital cameras with an almost unlimited number of pixels. A preferred CMOS stitching technique exploits the precise alignment accuracy of CMOS stepper processes by using specialized mask sets to repeatedly produce a single pixel array pattern many times on a single silicon wafer with no pixel array discontinuities. The single array patterns are stitched together lithographically to form a pixel array of many million pixels. A continuous multilayer photodiode layer is deposited over the top of the many million pixel array to provide a many million pixel sensor with a fill factor of 100 percent or substantially 100 percent.

In preferred embodiments the non-silicon materials are epitaxially grown on a silicon wafer. The bonding technique of preferred embodiments of the present invention utilizes lithographically pre-fabricated metallic interconnects to connect each of a number of pixel circuits on a readout circuit wafer to each of a corresponding number of pixel photodiodes on a photodiode wafer. The metallic interconnects are extremely small (with widths of about 2 to 4 microns) compared to prior art bump bonds with the solder balls of diameter typically larger than 20 microns. The present invention also provides alignment techniques to assure proper alignment of the interconnects during the bonding step.

  • Patent number: 7821624
    Abstract: A tracking system utilizing an excited state atomic line filter. The filter includes a metal vapor cell having an optical entrance port and an optical exit port and containing a metal vapor having a first excited energy state with a resonant frequency, and a second excited energy state. The cell has an absorption line, at or near a desired filter wavelength. The platform to be tracked, which could be an un-manned aerial vehicle has a beacon laser system located on it for producing a beacon laser beam at a wavelength within the narrow spectral band. The present invention solves the problem of lack of ground state resonant lines in at wavelengths substantially longer than those of visible light. Atomic line filters of the Faraday or Voigt crossed polarizer type are provided in which alkali metal atomic vapor in a vapor cell is excited with a pump beam to an intermediate excited state where a resonant absorption line, at a desired wavelength, is available.

  • Patent number: 7815865
    Abstract: A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container except when the liquid level in the tray drops to a level sufficient to allow air into the liquid container and to allow fluid to flow from the liquid container into the tray. The fluid flows from the liquid container into the tray until the level of liquid in the tray returns to the relatively constant level. The positioning of the syringe for drawing fluid is simplified in that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

  • Patent number: 7801493
    Abstract: A multi-coupler system for isolating radio signals in a transceiver, that includes a transmitter and a receiver, to permit simultaneous transmit by the transmitter and receive by the receiver through a single antenna in the exact same or nearby frequency ranges. This is done so that in-coming receive signals, transmitted from a remotely located radio, being detected by the receiver is much stronger than the portion of the transmit signal unintentionally coupled over by the co-site (or co-located) transmitter. The invention uses a special electronic circuit, termed the quasi-circulator, to couple the antenna to both the co-located receiver and the transmitter. The invention can also be used to couple several transceivers to a single antenna. The quasi-circulator circuit includes a simulated antenna load with an impedance matched to the antenna impedance.

  • Patent number: 7782251
    Abstract: A short range millimeter wave imaging radar system. The system includes electronics adapted to produce millimeter wave radiation scanned over a frequency range of a few gigahertz. The scanned millimeter wave radiation is broadcast through a frequency scanned transmit antenna to produce a narrow transmit beam in a first scanned direction (such as the vertical direction) corresponding to the scanned millimeter wave frequencies. The transmit antenna is scanned to transmit beam in a second direction perpendicular to the first scanned direction (such as the horizontal or the azimuthal direction) so as to define a two-dimensional field of view. Reflected millimeter wave radiation is collected in a receive frequency scanned antenna co-located (or approximately co-located) with the transmit antenna and adapted to produce a narrow receive beam approximately co-directed in the same directions as the transmitted beam in approximately the same field of view.
