  • Publication number: 20240280688
    Abstract: A method comprises performing, by a first coherent radar system on a chip configured to operate in a terahertz range between 0.1 THz and 1 THZ, a first radar scan of a target, the first coherent radar system being in physical contact with a first non-physical scanning device. The first non-physical scanning device then receives first scanning data from the first radar scan, and sends a coordination signal to a second non-physical scanning device. A second coherent radar system on a chip configured to operate in the terahertz range performs a second radar scan of the target, the second coherent radar system being in physical contact with the second non-physical scanning device. The second non-physical device receives second scanning data from the second radar scan, and the first and second scanning data are sent to a processor for a determination as to whether an impermissible object has been detected.

  • Patent number: 11784850
    Abstract: A communication network includes nodes configured into a wireless ring network operating at one or more millimeter-wave frequencies. At least one of the nodes is configured to send and receive millimeter-wave wireless signals through an obstruction. In accordance with an exemplary embodiment of the network, one or more of the nodes may include small, phased-array antennas and transceivers, configured with radio electronics to mitigate the path loss through certain obstructions, such as walls, floors, ceilings, and other barriers within buildings, as well as attenuation from free-space path-loss, including moisture in air (humidity). The network may include multiple pairs of nodes to form one or more wireless communication paths through various obstructions. This may allow a high-speed, wireless, multi-ring network to be established, for example, within a structure, such as a building, without requiring additional cabling or wiring.

  • Publication number: 20210405179
    Abstract: A method comprises scanning a subject with a coherent radar beam from a single chip operating in the terahertz range, and executing instructions, on a processor, to create one or more digital images based said scanning. One or more digital images are combined at the processor to form a super image, and based on the super image, the processor determines whether the subject is carrying a concealed object. if the subject is determined to be carrying a concealed object, and certain alert-generating rules are met, an alert is generated.
