  • Publication number: 20250134363
    Abstract: An endoscope tracker that measures the endoscope's motion using a pair of trackballs and two video cameras is provided. The trackballs measure real-time changes in the scope's position and rotation during an endoscopic procedure. The cameras detect scale lines on the scope's surface to correct accumulated trackball measurement errors. A dual modality tracking method measures the motion of the endoscope's insertion tube in real time, including insertion length, rotation angle, and their velocities. Optical trackballs measure the endoscope insertion tube's motion, and cameras correct cumulative errors. A purely optical endoscope tracker that measures the endoscope's motion is also provided, using video cameras and software that processes the images obtained from the video cameras to determine how the endoscope moves over time.

  • Patent number: 12218255
    Abstract: A vertical gallium nitride (GaN) PN diode uses epitaxial growth of a thick drift region with a very low carrier concentration and a carefully designed multi-zone junction termination extension to achieve high voltage blocking and high-power efficiency. An exemplary large area (1 mm2) diode had a forward pulsed current of 3.5 A, an 8.3 m?-cm2 specific on-resistance, and a 5.3 kV reverse breakdown. A smaller area diode (0.063 mm2) was capable of 6.4 kV breakdown with a specific on-resistance of 10.2 m?-cm2, when accounting for current spreading through the drift region at a 45° angle.

  • Patent number: 12217468
    Abstract: A device for detecting a coating applied to a surface includes a portable housing, a light source, a light detector, and a processing unit. The light source emits a first light having a first wavelength. The coating includes a fluorophore that re-emits a second light having a second wavelength, which is different than the first wavelength, in response to excitation by the first light. The light detector receives the second light re-emitted from the coating. The processing unit is adapted to determine a re-emission intensity of the second light and to determine a coverage metric of the coating based on the re-emission intensity of the second light. The coverage metric is then used to infer the efficacy of the coating.
