Publication number: 20070290672Abstract: A detector 1 for detecting a buried current carrying conductor comprises a digital signal processor 16 and a power supply unit 25. The power supply unit 25 is a switched mode power supply which incorporates a proportional integral differential controller feedback algorithm 33 and which is managed by the digital signal processor 16. The load 31 and source 26 voltage are monitored by the digital signal processor 16 and a look-up table. 35 is used to control a pulse width modulator 27, which drives a single ended primary induction controller 29. The self-generated noise of the power supply unit 25 does not interfere with the frequency bands of detection of the detector 1.Type: ApplicationFiled: June 20, 2006Publication date: December 20, 2007Inventors: Robert Worsley, Jeff Thompson, Richard Pearson, John Mark Royle

Patent number: 7304480Abstract: A radio mode selectivity block 41 for a detector 1 for detecting a buried current carrying conductor comprises a plurality of beat frequency oscillators 53 to center the bandwidth of detection of the detector 1 on target very low frequency (VLF) frequency bands. The frequencies of the beat frequency oscillators are chosen to fall within the VLF frequency bands used in a number of countries, so that the detector 1 can be used in radio mode in these countries without the need for local configuration.Type: GrantFiled: June 20, 2006Date of Patent: December 4, 2007Assignee: Radiodetection LimitedInventor: Richard Pearson

Publication number: 20060284616Abstract: A detector 1 for detecting a current carrying conductor determines the presence of a current carrying conductor one or more of passive or active modes. In the passive modes, the detector 1 detects either very low frequency radio signals re-radiated from a conductor or electromagnetic radiation produced by a conductor as a result of mains voltage carried in the conductor, or in a nearby conductor. In the active mode, an alternating signal from a dedicated signal generator is coupled into the buried conductor. Signals are induced in a pair of antennae 3, 5 in the detector 1, and the signals are processed in each of these modes simultaneously. The outputs of each of the modes are convolved to produce an audio and/or visual alert if a current carrying conductor is detected by any of these modes.Type: ApplicationFiled: June 20, 2006Publication date: December 21, 2006Inventors: Richard Pearson, Steve Benzie

Publication number: 20060284610Abstract: A detector 1 for detecting a current carrying conductor has a pair of vertically spaced antennae 3, 5 to detect the magnetic radiation produced by a current carrying conductor as a result of one or both of the mains power supply or an electromagnetic signal which is induced in the conductor by a dedicated signal transmitter. The detector 1 continuously calculates the depth of a buried conductor and if the buried conductor is above a predetermined minimum depth then the detector 1 triggers an audio and/or visual alarm. By reducing the sensitivity of the antennae 3, 5, the lateral offset range for which the alarm sounds is reduced and the location of a buried conductor can be determined.Type: ApplicationFiled: June 20, 2006Publication date: December 21, 2006Inventors: Jeff Thompson, Richard Pearson, Robert White

Patent number: 5459566Abstract: A method and apparatus for passing light bundles through a multiple pass sampling cell. The multiple pass sampling cell includes a sampling chamber having first and second ends positioned along a longitudinal axis of the sampling cell. The sampling cell further includes an entrance opening, located adjacent the first end of the sampling cell at a first azimuthal angular position. The entrance opening permits a light bundle to pass into the sampling cell. The sampling cell also includes an exit opening at a second azimuthal angular position. The light exit permits a light bundle to pass out of the sampling cell after the light bundle has followed a predetermined path.Type: GrantFiled: April 22, 1994Date of Patent: October 17, 1995Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Richard Pearson, Dana H.

Patent number: 4418388Abstract: An apparatus which permits the automated diagnosis of automobile engine electrical system waveform patterns is disclosed. Employed in conjunction with an addressable random access memory which stores digitized information concerning the waveform are further means which logarithmically reduce input amplitude values of the waveform and coordinates sampling times for the waveform with engine RPM so that the memory capacity is fully utilized. Input conversion of the waveform is accomplished by a tracking analog-to-digital converter using comparator means which also provides a waveform peak detector. Upon an address command, the memory output is input into a read only memory which provides an anti-log conversion of the logarithmic value stored in the memory, thereby providing an output corresponding to an actual value signal.Type: GrantFiled: August 14, 1980Date of Patent: November 29, 1983Assignee: The Allen Group Inc.Inventors: Clarence B.
