  • Patent number: 7280068
    Abstract: A microwave imaging system suppresses sidelobes in a microwave image captured using a sparse antenna array using an illumination system that operates in two different illumination modes. The antenna array including subarrays of antenna elements arranged in a sparse geometry to form complementary subarray patterns. The illumination system operates in a first mode to transmit microwave illumination to both of the complementary subarray patterns of the antenna array and receive reflected microwave illumination from both of the complementary subarray patterns of the antenna array to produce a first receive signal. The illumination system further operates in a second mode to transmit microwave illumination to a first one of the complementary subarray patterns of the antenna array and receive reflected microwave illumination from a second one of the complementary subarray patterns of the antenna array to produce a second receive signal.

  • Patent number: 7224314
    Abstract: A reflectarray utilizes switching devices with non-ideal impedance characteristics to vary the impedance of reflecting elements. The antennas of the reflecting elements are configured as a function of the impedance of the non-ideal switching devices to provide optimal phase-amplitude performance. In particular, the antennas are configured such that the impedance of each antenna is proportional to the square root of the impedance of the non-ideal switching devices when in an on state and when in an off state.

  • Patent number: 7203302
    Abstract: At least one call is routed based on a location of a calling party. A calling party calls a service corresponding to at least one predefined service area, and it is ascertained whether the calling party is within the at least one predefined service area. When the calling party is within the at least one predefined service area, it is determined which at least one predefined service area the calling party is in, and the routing for the call is determined based upon determining which at least one predefined service area the calling party is in. A route for the call to a destination for the service that corresponds to the determined predefined service area is identified based upon determining that the calling party is within the determined predefined service area.

  • Patent number: 7183963
    Abstract: An inspection system uses microwave radiation to capture a microwave image of a transportable item. The system includes a transmit scanning panel including a transmit array of transmit antenna elements, each being programmable with a respective phase delay to direct a transmit beam of microwave radiation toward a target of the transportable item for transmission of the microwave radiation through the target. The system further includes a receive scanning panel including a receive array of receive antenna elements, each being programmable with a respective phase delay to receive a receive beam of microwave radiation from the target. A processor measures the amplitude and phase of the microwave radiation in the receive beam to determine a relative value of a pixel within the microwave image of the transportable item based on a reference value of the pixel.

  • Patent number: 7112775
    Abstract: A technique for imaging an object with a coherent beam of electromagnetic radiation involves sequencing at least a portion of the coherent beam through a set of orthogonal transverse spatial modes and summing the output signals that result from set of orthogonal transverse spatial modes. To create an image of an object, the coherent beam is applied to multiple spots on the object and sequenced through the same set of orthogonal transverse spatial modes at each spot. The output signals generated from the sequencing are summed on a per-spot basis.

  • Publication number: 20060142982
    Abstract: A method for modeling fluid depletion in a reservoir is disclosed. A map is divided into cells. For each of the cells a value is stored that is based at least in part on a physical characteristic of the cell. At least one cell that contains a depletion location is identified along with a depletion amount corresponding to that location. An amount of walkers associated with the depletion location is determined. For each walker, a plurality of steps are calculated with each step to an adjacent cell. Each walker starts in the cell containing the depletion location associated with that walker. The visits of all the walkers are recorded by cell. The fluid depletion of each cell is then assessed based at least in part on the number of walker visits for each cell.

  • Patent number: 6965340
    Abstract: A security inspection system uses microwave radiation to image targets on a human subject or other item. The system includes an array of antenna elements that are programmable with a respective phase delay to direct a beam of microwave illumination toward a target on the human subject or item. The antenna elements are further capable of receiving reflected microwave illumination reflected from the target. A processor is operable to measure an intensity of the reflected microwave illumination to determine a value of a pixel within an image of the human subject or item. Multiple beams can be directed towards the human subject or item to obtain corresponding pixel values for use by the processor in constructing the image.

  • Patent number: 6898000
    Abstract: A nonpolarization-dependent method and apparatus for optical sampling of a user optical signal of a known frequency range (e.g., corresponding to 1550 nm wavelength) uses a probe signal in an unsplit form and applies a conversion {e.g., by sum frequency generation (SFG)} operation in a first stage to the probe signal and to a first polarization component of the user optical signal (e.g., ‘s’ component) to produce a first component of an output signal. In a second stage, a second polarization component of the user optical signal (e.g., ‘p’ component) is rotated by 90° to align with the first polarization component and then converted by mixing with the unsplit probe signal to produce a second component of an output signal. The first and second output component signals are both added and measured using a photomultiplier tube (PMT) or an avalanche diode.

  • Patent number: 6751413
    Abstract: Multiple signals are monitored, for example, by an instrument used for monitoring wavelength division multiplexing (WDM) transmission systems. For each monitored frequency channel, an active mask is initialized. The active mask includes an operating window defined by a minimum frequency, a maximum frequency, a minimum amplitude and a maximum amplitude. Each signal is monitored to determine when the signal strays outside the operating window. An alarm is generated when the signal strays outside the operating window.
