Abstract: Methods and systems provide a non-ionizing alternative to conventional mammography X-ray techniques, which expose patients to ionizing radiation, for breast cancer tumor detection, using a miniaturized (wafer scale) array of ultra wide band (UWB) radio frequency (RF) sensors operating at 60 GHz (non-ionizing—no X-ray type accumulative radiations) that have capability to use both linear and polarized sensors, tomography, and suppression of scattering for improved imaging. Coding techniques provide significant processing gain that is essential for the large attenuation of transmitted signals in breast tissue operating at these high frequencies. The increased bandwidth of UWB RF detection provides better depth resolution of breast and body tissue. Using polarization improves detection of abnormal tissues.

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.

Abstract: Methods and systems are provided for relocatable repeaters for wireless communication links to locations that may present accessibility problems using, for example, small unmanned aerial systems (sUAS). An sUAS implemented as an easy-to-operate, small vertical take-off and landing (VTOL) aircraft with hovering capability for holding station position may provide an extended range, highly secure, high data rate, repeater system for extending the range of point-to-point wireless communication links (also referred to as “crosslinks”) in which repeater locations are easily relocatable with very fast set-up and relocating times. A repeater system using beam forming and power combining techniques enables a very high gain antenna array with very narrow beam width and superb pointing accuracy. The aircraft includes a control system enabling three-dimensional pointing and sustaining directivity of the beam independently of flight path of the aircraft.

Abstract: Similar to cell based electronics systems that employ a sea of small unit cells in large scale arrays, such as thin film display monitors or semiconductor memories, an antenna array employs micron to centimeter size antenna pixelate cells that are integrated to form the plate of an antenna. Each row and column of cells in the antenna array may be accessed by digital logic and the RF transmission/reception state of the switchable cell changed. Thus, the antenna plate can be reconfigured and its radiating plate reformed to a specific pattern as an element of a larger array of antennas in wafer scale form.

Abstract: A tunneling accelerometer that can be implemented as a MEMS micro sensor provides differential sensing that minimizes large forces resulting from undesired environmental effects. Used as a seismic sensor, for example, the accelerometer exhibits maximum sensitivity for small seismic waves and suppresses very large seismic activities occurring at shallower depths. In one embodiment, detected current decreases from its maximum for stronger forces and is maximized for small vibrations. In another embodiment, separation of columns of top and bottom tunneling tip pairs, one column from the next, increases gradually so that the tunneling accelerometer suppresses sensitivity to large accelerations such as large seismic activity. A manufacturing process for the accelerometer provides reduced complexity for better yield.
