Patent number: 10386477Abstract: Methods and systems for detection of threats in secure areas are disclosed. Microwaves are transmitted into high traffic areas and are reflected off or transmitted through targets within that area. The resulting signals are detected at receiving antennas which are designed to have a high cross-polarization discrimination (XPD) such that co- and cross-polarizations of the resulting signals are separable for further processing. The receiving antennas of the present invention comprise elliptical antennas with a double-ridged waveguide on the interior and a conically-shaped exterior. This particular design for the receiving antennas allows to technologically obtain an XPD of about 30 dB or more for solid angles measured from a receiving antenna's boresight (the main lobe axis), and formed by rotating the corresponding 30-degree planar angle around the main lobe axis, the solid angles measuring approximately 0.84 sr, in a frequency range between 9.5 and 20 GHz.Type: GrantFiled: November 7, 2018Date of Patent: August 20, 2019Assignee: Apstec Systems USAInventors: Andrey Kuznetsov, Viktor Meshcheryakov

Patent number: 9928425Abstract: The present invention is a multi-threat detection method and system for high-traffic areas, such as airports, other mass-transit hubs, malls, symposiums, and the like. The detection methodology comprises a set of detection blocks, each performing different functions, and taking the information resulting from each block and entering it into one or more detection algorithms. The blocks comprise microwave detectors, co-polarization versus cross-polarization processors, magnetometers, and cameras (optional). The values calculated by the blocks are entered into machine learning algorithms which detect a threat if a threshold value is met. The detection occurs at a distance and the alarm may be silent, such that authorities are able to address threats without the target being aware. The alarm is also able to differentiate among varying threats based on the values calculated. No shadowing problems exist, and thus several targets may be monitored simultaneously without slowing down the speed of processing.Type: GrantFiled: June 5, 2017Date of Patent: March 27, 2018Assignee: APSTEC SYSTEMS USA LLCInventors: Andrey Kuznetsov, Viktor Meshcheryakov, Semen Semenov, Viktor Vorobyov, Dmitrii Vakhtin

Patent number: 9823377Abstract: The present invention comprises a multi-modal security checkpoint. The security checkpoint can simultaneously scan for and simultaneously identify hidden metallics (e.g., weapons, shrapnel) and non-metallics (e.g., explosives, dielectrics). The security checkpoint performs scanning and identifying at a rate of 15 or more frames per second for all targets within the inspection area. The security checkpoint comprises blocks for sending and receiving radiation signals, the blocks comprising transmitters and/or receivers, the blocks being configured to share information to compare cross- and co-polarizations of signals emitted. The security checkpoint combines many threat detection technologies into one checkpoint that allows it to be robust and detect a large variety of threats in mass transit hubs requiring high throughput processing capabilities.Type: GrantFiled: May 16, 2017Date of Patent: November 21, 2017Assignee: APSTEC SYSTEMS USA LLCInventors: Andrey Kuznetsov, Valery Averyanov, Igor Gorshkov

Patent number: 9784879Abstract: A method for standoff detection and analysis of objects comprises sending a signal through an inspection area, from a transmitter to a receiver, wherein the signal travels through objects in its path. If the signal encounters an object, through which it must travel, the speed of signal distribution decreases and its amplitude drops. A processor then determines the amplitude of the signal and whether the amplitude is above a given threshold, and if the threshold is met, further determining the shift in length of the signal's optical path, determining the thickness of the object, calculating the dielectric permittivity constant, and comparing this constant to known values of different materials to determine a preselected group of materials, to which the object in the inspection area belongs, and whether the inspected object belongs to a preselected group of dangerous objects. A system for detecting and analyzing such materials is also disclosed.Type: GrantFiled: June 30, 2014Date of Patent: October 10, 2017Assignee: APSTEC SYSTEMS LTDInventors: Andrey Kuznetsov, Valery Averyanov, Stanislav Vorobyev, Igor Gorshkov

Patent number: 9330549Abstract: A barrier and system for the protection of a crowd from terrorists, by evaluating each individual for any concealed prohibited items. Each individual is exposed to one or more screening mechanisms, controlled by a monitoring unit, while passing in an organized fashion through an enclosed walkway containing the screening mechanism, and exiting on the other side. When a prohibited object is detected, response is provided and the smart door device is locked to detain and isolate the suspected individual in the device structure's interior. The structure of the invention is also configured to deflect the blast created by a potential explosion and prevent harm to other individuals and structures nearby.Type: GrantFiled: April 23, 2014Date of Patent: May 3, 2016Assignee: APSTEC SYSTEMS USA LLCInventors: David Gustav Kellermann, Andrey Kuznetsov, Igor Gorshkov

Patent number: 9304190Abstract: The invention relates to the remote measurement of the dielectric permittivity of dielectrics. A 3D microwave and a 3D optical range images of an interrogated scene are recorded at the same time moment. The images are digitized and overlapped. A space between the microwave and optical image is measured, and a dielectric permittivity of the space between these images is determined. If the dielectric permittivity is about 3, then hidden explosive materials or components of thereof are suspected. The invention makes it possible to remotely determine the dielectric permittivity of a moving, irregularly-shaped dielectric objects.Type: GrantFiled: June 20, 2012Date of Patent: April 5, 2016Assignee: APSTEC SYSTEMS LTDInventors: Andrey Kuznetsov, Igor Gorshkov, Valery Averyanov
