Publication number: 20230077375Abstract: A rodless guide microwave radiation device, system, and method is disclosed for measuring at least one characteristic of a liquid in a vessel. A hollow metal waveguide conveys microwave radiation and is adapted to be disposed in a vessel for containing a liquid, the waveguide having a first end and a second end. A single chip radar sensor mounted on a PCB is disposed proximal to the first end of the hollow waveguide. The radar sensor is configured to transmit millimeter wavelength signals into the first end of the hollow waveguide for propagating down the waveguide toward the second end, and receive a return echo from the signal based upon a change in impedance upon encountering the liquid and propagating in the reverse direction of the waveguide, the single chip radar sensor including electronic circuitry for determining at least one characteristic of the liquid located in the waveguide based on detection of an impedance change according to time domain reflectometry.Type: ApplicationFiled: July 25, 2022Publication date: March 16, 2023Inventors: Chester Wildey, Gagik Farmanyan, Benjamin N.

Patent number: 9545223Abstract: Disclosed is a functional NIRS imaging system including an elastomeric cap, a set of transmit optical fibers and a set of receive optical fibers terminating on the inside surface of the elastomeric cap. A pair of light sources combines to produce a collimated light beam at two wavelengths. An optical modulation system, converts the light beam into a plurality of probe light beams, modulates the plurality of probe light beams and directs each probe light beam into a transmit fiber. An optical detection system accepts scattered photons from subcutaneous tissue underneath the elastomeric cap as a plurality of collected light beams and converts them into a time series of electronic images, stores the electronic images into the memory and processes the electronic images using. The system displays the resulting image on a display as a hemoglobin oxygen saturation map.Type: GrantFiled: November 28, 2012Date of Patent: January 17, 2017Assignee: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Duncan MacFarlane, Chester Wildey, Georgios Alexandrakis, Bilal Khan

Patent number: 7729201Abstract: A method and apparatus for spread spectrum distance and for spread spectrum velocity profile measurement is provided where the short pulse of traditional ultrasonic and radar level gauges is replaced by low peak power direct sequence spread spectrum (DSSS) modulated energy. An echo sequence subtraction process is provided that increases the signal to noise ratio of each echo sequence thus increasing the dynamic range of the system. In addition to providing a higher signal to noise ratio (SNR), better precision and accuracy in ranging Doppler applications and the ability to use lower peak power transmissions, the system is more immune to interference from the environment and allows for less expensive and less bulky ultrasonic transducers.Type: GrantFiled: March 21, 2007Date of Patent: June 1, 2010Inventor: Chester Wildey
