  • Patent number: 12147145
    Abstract: Disclosed herein is the detection of dangerous dielectric materials (explosives) and dangerous non-explosive and/or prohibited items. The detection is based on a broad bandwidth nonlinear radar system, driven by a highly stable optical frequency comb. The disclosed approach allows for the spatial resolution of the interrogated object in complex settings. Detection of dangerous materials and non-explosive chemical prohibited items is disclosed. The chemicals can be identified under clothing, within boxes, or other dielectric enclosures.

  • Patent number: 12038489
    Abstract: Systems and methods are described, and one method includes illuminating a target-of-interest (TI) with an RF energy configured to effect, over a time duration extending from a first time to a second time, an increase in a temperature of the TI. At a first detection time within the time duration, a first temperature NQR signal spectrum of the TI is detected, and a corresponding first temperature NQR spectrum data set is generates. At a second detection time, subsequent to the first detection time, a second temperature NQR signal spectrum of the TI is detected and corresponding second temperature NQR spectrum data set is output. Based at least in part on the first temperature NQR spectral dataset and the second temperature NQR spectral dataset, the TI is classified between including the SI and not including the SI.

  • Publication number: 20230358734
    Abstract: Disclosed is an enabling process for high throughput manufacturing of large variety of chemical and biological sensors that utilize well-developed spin-based sensing of analyte binding. A method for producing a nanometer scale analyte specific sensor may be provided, that includes providing a first material (such as a diamond) having a luminescent center (such as an NV center) within predetermined distance (such as 2-5 nm) of a first surface, where the luminescent center configured to emit within an optical emission range, providing photochemically active molecules (such as molecules with a photo-uncaging protective group) where an optical absorption range of the photochemically active molecules at least partially overlaps the optical emission range, coating the first surface of the first material with the photochemically active molecules, and may include placement of the photochemically active surface molecule within a distance smaller than the Forster Resonant Excitation Transfer (i.e.

  • Publication number: 20230194702
    Abstract: Systems and methods are described, and one system includes a three-dimensional (3D) geometric tracker connected to a multiband (MB) inverse synthetic aperture array radar (ISAR), and a classification/alarm logic. The MB ISAR includes spatially distributed radar transmitters (TXs) and receivers (RXs), a TX/RX allocation logic, and a tomographic (TM) image logic. The TX/RX allocation logic is configured to receive 3D tracking data from the 3D geometric tracker, indicating subject 3D position and 3D orientation and, in response, dynamically allocate TXs and RXs to maintain MB illumination of and maintain MB reception of multiple scatter angles from subjects. The TM image processor is configured to construct TM images from the scatter angles, using 3D tracking data, for input to the classification and alarm logic. Optionally, the TX/RX resource allocation logic is configured to receive situation feedback data, for feedback adjusting of allocation of TXs and RXs.
