Abstract:
A microwave device for inactivation of viruses is disclosed. The microwave device comprising a housing and a field generator. The housing has a cavity configured to receive an object contaminated with viruses within the cavity and the field generator is configured to irradiate the cavity with microwave energy at a band of frequencies and a power level configured to inactivate the virus. The cavity is located within a near-field of a radiation pattern produced by the field generator at the band of frequencies and the microwave energy causes a dipole vibration on the virus that causes the virus to fracture.
Abstract:
Methods and systems are disclosed for scalable antenna arrays that may be built up using pluggable tiles that have low distortion, flat band high gain, and structured to channelize the signals into narrow bands that may be 40 MHz or even smaller bandwidth apart. Antenna array tiles may employ traveling wave tube (TWT) components and wafer scale arrays. H-topology, equal length, feed networks connect the signals to antenna elements. The fractal-like, recursively repeating at different size scales, structure for the H-tree feed networks, implemented using pluggable tiles, facilitates the scalability of the high gain waveguide antenna array. System integration across the 75-115 GHz spectral band implements scalable aperture architecture with emphasis on addressing considerations of the TX power requirement, feed network, channelizing signals at different frequency bands using specially designed diplexers and combiners, cooling, component placement, and isolation.

A drone is provided with a convolutional neural network that processes a fusion of video and radar data to identify and avoid collision threats. The drone includes a transmitter for transmitting the video data to a remote convolutional neural network for identifying structures and for further identifying threats or faults with the structures.

There is provided a system and method for monitoring of fractured wells and conventional wells to detect leaks. The method comprises interrogating a plurality of resonant tags using a modulated RF signal transmitted from an interrogator, wherein the plurality of resonant tags are dispersed within a channel.
Abstract:
Systems and methods for screening, where a subject walks through or in front of a passive detector (or scanning unit) to be screened for possession of unauthorized electronics devices, provide for detecting and monitoring electronics systems not authorized to be used in secure areas. By focusing a very narrow beam width antenna array, individuals can be screened who may have concealed electronics devices that can pose danger to the surroundings. There is no need for removing clothing or accessories such as a jacket or backpack, for example. The detection system may include a frequency scanned passive receiver that captures a signal from a detected electronics device, measures its strength, and identifies the device or classifies it according to a pre-determined set of categories (e.g., cellular phone, camera, or global positioning system (GPS)).
Abstract:
An ultra-wideband (UWB) radar imaging system is carried by a mobile platform—such as an aircraft—the UWB radar imaging system including multiple UWB radar sensors; the UWB radar sensors transmitting a high resolution radar signal using an array of power amplifiers and corresponding polarizing antenna arrays to form spatial power combining and beam forming from each UWB radar sensor; and receiving reflections using an array of low noise amplifiers and corresponding antenna arrays to form spatial power combining from the reflections at each. UWB radar sensor; processing the radar sensor data from the UWB radar sensors by an imaging processor for detecting a ballistic projectile; and providing trajectory information of a detected ballistic projectile on a display. Trajectory modeling enables fusing the radar sensor data with optical or thermal imaging data and the trajectory information to display a probable source location of the detected ballistic projectile.

Abstract:
A multi-sensor system is disclosed for detecting victims that may be trapped or buried (for example, earthquake survivors in collapsed buildings) and for accurately and safely locating such victims for safe and efficient rescue. An ultra wide band (UWB) radiometer sensor can detect and precisely calculate the position of the victim relative to a known position of a sensor probe or a monitoring unit of a sensor system. A sensing probe may be guided toward a victim and provide a combination of sensors and transducers (e.g., radiometer, optical and infrared camera, acoustic or sound transducers such as microphone and speaker) that may allow a probe operator remote from the subject (e.g., victim) to also determine the condition and status of the victim and communicate with the victim. With unique coding of the UWB signals, multiple units can be used together to triangulate a more exact position of each victim.
Abstract:
An array of paired V-band sensors is provided to act as a virtual fence to detect human intrusion. Each sensor includes a rotating circuit board that includes an antenna array. The sensor pivots the circuit board with regard to a weight base to align with an opposing sensor. By alternatively transmitting and receiving with regard to the opposing sensor, a V-band bistatic radar system is enabled that detects human intrusion between the opposing sensors.
Abstract:
A small unmanned aerial system (sUAS) is used for aerial and on the ground surveillance while an operator of the sUAS, or other personnel, remain at a safe distance. The sUAS system can perform an autonomous landing and can be operated at an extended, e.g., greater than 100 meters, standoff from the detection apparatus and potential harm. The sUAS may be implemented as an easy-to-operate, small vertical take-off and landing (VTOL) aircraft with a set of optical, thermal, and chemical detection modules for performing aerial surveillance and ground surveillance after landing.
