  • Patent number: 10321826
    Abstract: The dynamic positioning of sensors, which exploit the mechanical and physiological changes in tissues, can significantly increase the performance in characterization of tumors. Here, we disclose the Optical Dynamic Imaging (ODI) System for tumor characterization. ODI System estimates size, depth, elastic modulus and optical properties of embedded objects. The ODI System consists of a tactile imaging sensor (TIS), and a near infrared diffuse spectral imaging. To obtain mechanical properties of the target, we compress the region of interest with the probe, then the light from the probe is scattered and captured by the camera as a tactile image. On the other hand, using a light source and the camera as a detector, we obtain the diffuse spectral images. From these images, we compute the absorption coefficient of the embedded tumor phantom. We move the source-detector simultaneously and collect optical information. We termed this maneuver as dynamic positioning.

  • Patent number: 10015394
    Abstract: Provided is a visual vehicle speed estimation system based on camera output and calibration for such a vehicle speed estimation system. The calibration allows use of the system where the absolute camera position is unknown. Calibration determines an absolute-position-independent relationship between an image space placement and a physical space position relative to the camera. The calibration is done on the basis of camera output using vehicle features of known dimensions and some assumed physical constraints related thereto to provide a conversion relationship between image coordinates and physical space coordinates in a physical space defined in relation to the camera. This relationship is then used to estimate vehicle speeds based only on the visual information provided by the camera. Abstract is not to be interpreted as limiting.

  • Patent number: 8373141
    Abstract: Dosimeter chips are widely distributed over a territorial area. This is followed by photographing the area from above to produce a color photograph. The color photograph is compared with radiation/color calibration data for the dosimeter chips. The total radiation accumulation is determined from the calibration data. The invention is for emergency use after civil accidents, for ascertaining a threat to military personnel before entering the battlefield or for interrogating a ship at sea.

  • Publication number: 20130020508
    Abstract: A method of determining the radiation type and energy distribution of a radiation source that outputs radiation. The method including providing a plurality of detector materials and exposing the plurality of detector materials to the radiation. Each of the plurality of detector materials stores a signal in response to being exposed to the radiation. The signals are representative of the radiation. The plurality of detector materials is stimulated to output the signals as measured signals. These measured signals are used to determine the radiation type and energy distribution of the radiation.

  • Publication number: 20120273697
    Abstract: To overcome the disadvantages introduced by using UV sensors to detect the intensity of UV light in water purification apparatuses, the present invention provides a novel detection apparatus to “visualize” the quality of water in the form of visible light, instead of digitizing the intensity of UV light. The detection apparatus comprises a first detection window, coated with a first material for converting a received first ultraviolet light into a first visible light, wherein the first ultraviolet light is emitted from an ultraviolet light source and traverses the liquid, and the apparatus further mixes the first visible light with a second visible light to generate a third visible light. The different color of the third visible light can represent the different quality of the water.

    Abstract: One embodiment disclosed relates a method of detecting a patterned electron beam. The patterned electron beam is focused onto a grating with a pattern that has a same pitch as the patterned electron beam. Electrons of the patterned electron beam that pass through the grating un-scattered are detected. Another embodiment relates to focusing the patterned electron beam onto a grating with a pattern that has a second pitch that is different than a first pitch of the patterned electron beam. Electrons of the patterned electron beam that pass through the grating form a Moiré pattern that is detected using a position-sensitive detector. Other embodiments, aspects and features are also disclosed.
