  • Patent number: 9291494
    Abstract: A solar blind corona camera designed specifically for use on 60 Hz or 50 Hz AC power distribution equipment is based on the fact that electrical discharge corona only occurs above some voltage threshold level on the positive and negative voltage peaks of the AC power waveform. Between these peaks, when the AC voltage is below the discharge corona voltage threshold, the electrical discharge and resulting corona are extinguished. An image sensor is used to both capture the corona-plus-ambient light image during the corona period and the ambient light image during the non-corona period. The ambient light image is then subtracted from the corona-plus-ambient light image leaving only the corona light image which is annunciated and displayed along with the ambient light image. This process effectively renders the corona camera solar blind so it can be used both at night and during daylight.

  • Patent number: 9255954
    Abstract: A remote phase identification system identifies the unknown phase attribute of any energized conductor within a three-phase power distribution network. A base station at a reference location obtains a reference phase each GPS second and stores it on one or more servers. A field probe at a remote location obtains an instantaneous phase measurement at a GPS second and communicates this phase to a field client. The field client communicates with the server either by wireless Internet or satellite modem to compare its field location phase measurement with the reference location phase measurement taken at the same GPS second. Field client tagging reference phase configuration files are automatically created for any circuit. Configuration files can be named, saved, and loaded and are used by the field client to identify and display the unknown field location phase attribute. A field client can be any personal computer, smartphone, or personal digital assistant.

  • Patent number: 9065718
    Abstract: A Coded Orthogonal Frequency Division Multiplexing (COFDM) communication systems is implemented in which each subcarrier data stream is individually FEC encoded instead of FEC encoding the overall input data stream as implemented in conventional COFDM systems. Specifically, each subcarrier is independently encoded using pseudo orthogonal QPSK M-QAM FEC modulators, transmitted, and decoded using pseudo orthogonal QPSK M-QAM FEC demodulators. Multiplexers and demultiplexers randomize subcarrier symbols across all subcarriers to prevent contiguous subcarrier data errors due to fading or corruption by narrowband interference. This technology can be applied to many wireless and wired communication systems including wireless underwater RF communications.

  • Patent number: 9046558
    Abstract: A probe uses a small diameter insulated needle to accurately penetrate the jacket and thin outer semiconductor sheath of URD cable so as to capacitive couple to the high voltage center conductor and determine its energized status (live or dead) and phase attribute. A precision needle depth gauge, mechanical hard stop, and digital display ensures that the needle does not penetrate the thick center conductor insulation material and provides an indication of the center conductor voltage. The probe can be combined with either internal or external phase identification circuitry to determine the phase attribute of the URD cable.

  • Patent number: 8742977
    Abstract: A bistatic radar receiver is located on a wind turbine and surrounded by multiple bistatic transmitters to detect and precisely track the positions of nearby birds. Bird target reflections from multiple transmitters are received by the radar receiver and their position and track determined from the transmitter locations, receiver location, and measured transmitter-to-target-to-receiver ranges. Target position and altitude accuracy is similar to GPS. When birds are detected to be on a collision course with the wind turbine, a deterrent is activated to scare them away. Deterrents can be flashing strobe lights, intense sound, air cannon, or any other effective bird deterrent.

  • Patent number: 8723719
    Abstract: A bistatic radar receiver is centrally located within an array of multiple bistatic transmitters at an airport to precisely determine bird positions and altitudes. Bird target reflections from multiple transmitters are received by the radar receiver. Target location is determined by the transmitter location, receiver location, and measured transmitter-to-target-to-receiver ranges. Target position and altitude accuracy is similar to GPS. The radar receiver antenna is composed of a vertical array of elements and rotated 360 degrees in azimuth. The output of each element is downconverted, digitized, and digitally beamformed to provide multiple simultaneous antenna beams each electronically scanned in elevation. When bistatic transmitters cannot be deployed, a narrow-azimuth wide-elevation transmit antenna beam is overlapped with a wide-azimuth narrow-elevation receive antenna beam electronically scanned in elevation to provide a composite narrow azimuth and elevation beamwidth.

  • Patent number: 8717963
    Abstract: A wireless star topology communication network is implemented in which a centrally located access point supports a very large number of fixed location nodes distributed over a large metropolitan area. Communication is by direct sequence spread spectrum modulating m-ary quadrature amplitude modulation symbols. The access point and all nodes are synchronized using GPS or other means to prevent data collisions. Multiple access is primarily based on signal propagation time between the access point and a node which allows nodes at different ranges to use the same direct sequence code.

  • Patent number: 8665985
    Abstract: A low level secondary communication signal is summed with an existing primary communication signal in a manner that prevents interference to the existing primary communication signal while providing secondary communication signal benefits such as increased data rate, range, or interference immunity. Examples are presented in which a M-QAM secondary signal is summed with either an ATC Mode S PPM reply or DPSK interrogation primary signal. Legacy Mode S transponders, TCAS, and ADS-B equipment continue to demodulate and decode the primary signal information in accordance with preexisting formats while new enhanced equipment obtains the benefits of the secondary signal.

  • Patent number: 8570024
    Abstract: A phase identification system identifies the unknown phase attribute of any energized conductor within a three-phase power distribution network by comparing remote location non-contact phase identification instrument phase measurements to phase measurements taken at a reference location. The vector sum of three-phase conductor voltages at the remote measurement location are used to determine the near, center, and far conductor phase attributes of the three-phase lines being measured. This allows phase attributes of high overhead conductors to be determined from ground level using a non-contact handheld instrument.

  • Patent number: 8570211
    Abstract: A non-scanning radar system is installed on an aircraft to detect and avoid bird strikes or collisions with other airborne hazards. Target amplitude, range, and Doppler tracking versus time are used to qualify the collision threat. Avoidance is based on a quick minor altitude change by the pilot or autopilot to exit the imminent bird or other airborne hazard altitude window. In one embodiment, a bistatic passive radar receiver antenna is used in conjunction with an existing geostationary satellite signal. Range and Doppler information are obtained via cross correlation processing of the hazard reflection signal with a direct path reference signal from the satellite.

  • Patent number: 8558734
    Abstract: A ground based avian radar receive antenna is implemented using a vertically oriented offset parabolic cylindrical antenna. The desired azimuth beamwidth is determined by the width of the parabolic cylinder reflector surface and the desired elevation beamwidth by the height of the parabolic cylinder reflector surface. A vertical array of antenna elements is mounted along the vertical focal line to provide electronic scanning in elevation. Low sidelobe levels are obtained using tapered antenna element illumination. Low cost modular construction with high reflector accuracy is obtained by attaching a thin metal reflector to thin ribs machined or stamped in the shape of the parabolic cylinder reflector surface. The antenna is enclosed in a radome and mechanically rotated 360 degrees in azimuth.

  • Patent number: 8437431
    Abstract: A communication system includes a transmitter which generates transmit phase points defined to be the vector sum of two or more QPSK signals. Forward error correction encoding is performed independently for the QPSK signals. In a receiver, alternate hypotheses are formed about the potential values that might have been transmitted for all the QPSK signals, and offset phase points are defined for each hypothesis. For the correct hypothesis, the offset phase point has the effect of canceling all the two or more QPSK signals from the combined communication signal leaving only circuit and channel noise added during transmission. Branch metrics are responsive to Euclidean distances between the received signal and the hypothesized transmitted signal. A decoder is configured to accept and reject the hypotheses based on the noise statistics and desired communication application symbol error rate.

  • Patent number: 8368583
    Abstract: An aircraft avian radar is implemented using multiple axial beam antennas mounted on an aircraft. Target range is determined by radar range. Target azimuth and elevation position is determined by triangulation. An end-fire array antenna composed of a series of monopole antenna elements enclosed inside a long thin protective cover fashioned in the form of a stall fence is mounted on the wings, tail, or fuselage to produce a low drag axial beam antenna pattern directed ahead of the aircraft. Other axial beam antenna choices include helical, pyramidal horn, and conical horn antennas mounted on or inside various forward facing surfaces of the aircraft.

  • Patent number: 8279109
    Abstract: An aircraft avian radar is implemented using an existing aircraft transponder, Mode S, or TCAS installation as the radar transmitter. To eliminate self jamming of low level avian target signals by high level transmitter signals, the ending period of the transmission signal is digitized and cross correlated with the ending period of reflected avian target signals received after the transmission signal has ended. In a first implementation, the current transponder antenna is used for both transmission and reception. In a second implementation, an external receive only antenna is mounted in a position that maximizes the transmit antenna to receive antenna isolation. In a third implementation, a signal canceller and sample of the transmit signal are used to cancel or null out as much transmit signal as possible that couples directly to the receive antenna.
