Patent number: 10222465Abstract: In an embodiment of the disclosed technology, a visual output of data from a ground-penetrating radar and magnetic field measuring device is displayed on a visual medium. The display has a first exhibition of output from the ground-penetrating radar device and a second from a magnetic field measuring device, such as a very low frequency (VLF) receiver. Using an identical axis, such as an X-axis measuring time or distance, output of each device is exhibited and overlaid over one another. In this manner, one can detect (using two different methodologies and uses) the visual exhibition of both to best determine the location of a metal or electrical target.Type: GrantFiled: December 29, 2015Date of Patent: March 5, 2019Assignee: Geophysical Survey Systems, Inc.Inventor: Jeffrey R Feigin

Patent number: 9739880Abstract: The disclosed technology includes a device and method of use for direct printing and ink or other marking, in conjunction with GPR techniques. In a most basic embodiment of the disclosed technology, a relevant date, time, filename, and other parameters are printed or otherwise physically exhibited on the measurement surface, so that RADAR files can be later attributed to a specific data collection site. In a more advanced embodiment of the disclosed technology, actual RADAR target information is printed, or otherwise physically exhibited, on the measurement surface, such as while measuring, or substantially while measuring, the surface and substrate beneath with GPR.Type: GrantFiled: June 19, 2015Date of Patent: August 22, 2017Assignee: GEOPHYSICAL SURVEY SYSTEMS, INC.Inventor: Jeffrey R Feigin

Patent number: 9057782Abstract: Embodiments of the disclosed technology use high-speed interpolated (interdigitated) sampling for the specific purpose of GPR (Ground-Penetrating RADAR). This technology solves several issues associated with high-speed sampling in GPR which included 1) dynamic range limitations, 2) regulatory compliance issues, 3) sampler core offset error, and 4) timing errors. High-speed interpolated sampling GPR is implemented using a high-speed ADC in combination with trigger logic (such as an FPGA) and a programmable delay generator. The FPGA or other trigger logic generates a series of randomly dithered trigger pulses. A variable delay generator (or “Vernier”) is synchronously controlled in order to produce the fractional timing. The timing of the pulses is randomly or pseudo-randomly dithered, and the phase of the interpolation is shuffled in order to avoid producing discrete spectral lines in the radiated RADAR signal.Type: GrantFiled: August 17, 2012Date of Patent: June 16, 2015Assignee: GEOPHYSICAL SURVEY SYSTEMS, INC.Inventor: Jeffrey R.

Patent number: 8238494Abstract: A radio frequency (RF) receiver having an analog gain control section for controlling the gain of a received RF signal, and a digital demodulator section for demodulating the output of the gain control section, includes an analog GO circuit connected to recognize the presence of a data packet within a received RF signal in the analog gain control section, and in response to produce an analog GO signal, a digital GO circuit connected to recognize the presence of a data packet within the received RF signal from the digital demodulator section, and in response to produce a digital GO signal, and control circuitry connected to enable gain control functions within the analog gain control section and digital demodulator functions within the digital demodulator section in response to respective analog and digital GO signals.Type: GrantFiled: November 4, 2008Date of Patent: August 7, 2012Assignee: MediaTek, Inc.Inventors: Phillip M.

Patent number: 8115667Abstract: Embodiments of the disclosed technology comprise an air-launched antenna system with interference-rejection technology that operates in analog hardware as well as by way of a digital filtering technique. Using an inline analog hardware filter combined with a digital filter, to determine transversal (and/or recursive) coefficients, in a calibration phase, a measurement system may be configured to remove interference and the effects (such as a delay or temperature variation) which result from use of an analog filter. In this manner, the resulting measurements of a composition of road surface are more accurate and useful.Type: GrantFiled: November 17, 2009Date of Patent: February 14, 2012Assignee: Geophysical Survey Systems, Inc.Inventors: Jeffrey R Feigin, Alan E Schutz

Patent number: 8102298Abstract: Embodiments of the disclosed technology comprise a ground penetrating radio device and methods of use for obtaining greater resolution. This is achieved by measuring the composition/reflection off a homogeneous material (e.g., metal plate), determining coefficients to correct the measured/reflection in order to make the measurements look like an idealized reference signal, and then using these coefficients in a digital filter to correct measurements/a reflection off a heterogeneous material, such as a road surface. In this manner, the composition of the heterogeneous material is determined with greater accuracy.Type: GrantFiled: June 10, 2011Date of Patent: January 24, 2012Assignee: Geophysical Survey Systems, Inc.Inventors: Jeffrey R Feigin, Alan E Schutz

Patent number: 7457378Abstract: An RF receiver includes an analog GO circuit that recognizes the presence of a data packet within a received RF signal in the receiver's analog gain control section, and in response produces an analog GO signal, and a digital GO circuit that recognizes the presence of a data packet from the receiver's digital demodulator section, and in response produces a digital GO signal. Gain control functions within the analog gain control section, and digital demodulator functions within the digital demodulator section, are enabled in response to respective analog and digital GO signals. The system is capable of distinguishing a valid data packet from noise, co-channel interference and adjacent panel interference. A symbol timing recovery circuit within the receiver identifies periodic samples of a data packet preamble that most closely match the preamble bits, with the receiver employing a continuation of the identified periodic samples to decode the remainder of the data packet.Type: GrantFiled: March 2, 2004Date of Patent: November 25, 2008Assignee: MediaTek, Inc.Inventors: Phillip M.
