Patent number: 9207316Abstract: A multi-modal ground penetrating radar includes a radar set configured to launch predistorted double-sideband (DSB) suppressed-carrier modulated continuous waves (CW) to illuminate and penetrate a ground surface. A variable frequency modulator is connected to modulate a continuous wave (CW) carrier frequency generator within the radar set to yield a double-sideband suppressed carrier output. A lateral single-file array of antennas is configured to be flown closely over the surface of the ground. A multiplexing switch is connected to the array of antennas and configured to selectively switch individual ones of the antennas to the radar set. Any early arriving signals returned from geologic clutter and surface reflections are suppressed in synchronous detection in relation to signals received by the array of antennas from less shallow depths. Interesting objects below the ground surface are detected and located by the late arriving signal reflections.Type: GrantFiled: January 10, 2014Date of Patent: December 8, 2015Assignee: Stolar, Inc.Inventors: Larry G. Stolarczyk, Richard B. Main

Publication number: 20140104979Abstract: A ground-penetrating tunnel-detecting active sonar launches two different monotonic acoustic beams down into the ground from the surface. If the two separate monotonic acoustic waves arrive at a stress field, they will mix and produce a frequency difference heterodyne due to the inherent pressure nonlinearities in the solid medias. Any sonar returns are bandpass filtered so only an acoustic frequency difference heterodyne can pass through. The existence of a tunnel is revealed by the return of acoustic frequency difference heterodynes all coming from a more-or-less horizontal line of phase-delayed sources and directions. These phase differences can be derived from the vector values provided by the acoustic vector sensor. Three or more acoustic vector sensors on the surface can be used effectively to provide triangulations down to the tunnel to better estimate the tunnel track.Type: ApplicationFiled: December 18, 2013Publication date: April 17, 2014Applicant: STOLAR RESEARCH CORPORATIONInventors: Gerald L.

Publication number: 20140100973Abstract: A payment device presents a matrix barcode on a smartphone display screen for scanning by a merchant at a point-of-sale terminal. The consumer authenticates with their payment processor by logging in with their smartphone through a back channel. A successful log-in is rewarded with a matrix barcode the consumer can allow the merchant to scan if the particulars and price of the proposed transaction are acceptable. A transaction summary and request for approval arrive back at the consumer's smartphone through the back channel. Approval can be indicated by the entry of a user PIN code, and the transaction is complete.Type: ApplicationFiled: December 6, 2013Publication date: April 10, 2014Applicant: CRYPTITE, LLCInventors: Kerry D. Brown, RONALD P. KNAPP, RICHARD B. MAIN

Publication number: 20140043183Abstract: Acoustic heterodyne radars use accurately surveyed or otherwise known locations to repetitively launch at least two, intense acoustic tone soundwaves (F1, F2) into an underground area of search. An acoustic receiver is tuned to receive either the sum (F1+F2) or difference (|F1?F2|) heterodynes and is configured to measure and log the overall relative attenuation and roundtrip travel times of the soundwaves, like a typical radar. Any acoustic heterodynes received are assumed to be the work of non-linearities and stresses in the search area. A full-waveform three dimensional tomography algorithm is applied by a graphics processor to the collected and logged data to generate maps and profiles of objects beneath the ground which are interpreted to have produced the acoustic heterodynes.Type: ApplicationFiled: August 9, 2012Publication date: February 13, 2014Inventors: Larry G.

Patent number: 7659847Abstract: A coal-mining machine uses a ground-penetrating radar based on a software-definable transmitter for launching pairs of widely separated and coherent continuous waves. Each pair is separated by a constant or variable different amount double-sideband suppressed carrier modulation such as 10 MHz, 20 MHz, and 30 MHz. Processing suppresses the larger first interface reflection and emphasizes the smaller second, third, etc. reflections. Processing determines the electrical parameter of the natural medium adjacent to the antenna. Deep reflections at 90-degrees and 270-degrees create maximum reflection and will be illuminated with modulation signal peaks. Quadrature detection, mixing, and down-conversion result in 0-degree and 180-degree reflections effectively dropping out in demodulation.Type: GrantFiled: March 23, 2008Date of Patent: February 9, 2010Assignee: Stolar, Inc.Inventors: Igor Y.

Processing determines the electrical parameter of the natural medium adjacent to the antenna. The modulation process may be the variable or constant frequency difference between pairs of frequencies. If a variable frequency is used in modulation, pairs of tunable resonant microstrip patch antennas (resonant microstrip patch antenna) can be used in the antenna design. If a constant frequency difference is used in the software-defined transceiver, a wide-bandwidth antenna design is used featuring a swept or stepped-frequency continuous-wave (SFCW) radar design.Type: GrantFiled: October 23, 2007Date of Patent: February 2, 2010Assignee: Stolar, Inc.Inventors: Larry G.

Patent number: 7629790Abstract: A system for the electronic detection of military threats includes an electromagnetic (EM) gradiometer for detecting secondary EM waves scattered from objects illuminated by a primary EM wave existent in a local area. A right magnetic dipole antenna and a left magnetic dipole antenna are included in the EM gradiometer for receiving the secondary EM waves and able to reject the primary EM wave. A synchronizer derives a reference signal to the EM gradiometer from the primary EM wave. A synchronous detection processor makes measurements of the phase and amplitude of the secondary EM waves. A graphical user interface (GUI) is used to display information about the location of objects assessed to be threats in the local area that were computed from the measurements of the phase and amplitude. A vehicle may be used to transport the EM gradiometer over the local area during periods the objects are being radio illuminated.Type: GrantFiled: October 22, 2007Date of Patent: December 8, 2009Assignee: Stolar, IncInventors: Larry G.

Publication number: 20080218170Abstract: An aerial electronic system for detection of surface and underground threats comprises an electromagnetic (EM) gradiometer flown aloft over the possible ground and underground threats to a convoy. The EM gradiometer is disposed in a Styrofoam torpedo shaped pod that is towed in flight behind an airplane. An illumination transmitter and loop antenna mounted to the airplane radiate a primary EM wave that travels down to the ground surface and penetrates beneath. Frequencies of 80 KHz to 1 MHz are selected according to whether the targets are laying on the surface or deeply buried. Detonation wire pairs, buried cables and pipes, and other conductors will re-radiate a secondary wave that can be sensed by the EM gradiometer. A reference sample of the transmitter signal is carried down a fiberoptic from the airplane to the towed pod. This signal is used in the synchronous detection to measure the secondary EM wave phase.Type: ApplicationFiled: October 22, 2007Publication date: September 11, 2008Inventors: Larry G.
