  • Patent number: 11228310
    Abstract: Optically isolated micromachined (MEMS) switches and related methods are described. The optically isolated MEMS switches described herein may be used to provide isolation between electronic devices. For example, the optically isolated MEMS switches of the types described herein can enable the use of separate grounds between the receiving electronic device and the control circuitry. Isolation of high-voltage signals and high-voltage power supplies can be achieved by using an optical isolator and a MEMS switch, where the optical isolator controls the state of the MEMS switch. In some embodiments, utilizing optical isolators to provide high voltages, the need for electric high-voltage sources such as high-voltage power supplies and charge pumps may be removed, thus removing the cause of potential damage to the receiving electronic device. In one example, the optical isolator and the MEMS switch may be co-packaged on the same substrate.

Additionally or alternatively, multiple crystals can be associated with each of a plurality of photodetectors. A gamma ray hit on a specific crystal is then determined by a table lookup of adjacent photodetectors that register equal light intensities, and the crystal common to such photodetectors is identified as the location of the hit.

  • Patent number: 10502844
    Abstract: An imaging method and device are described for improving the performance of a gamma camera by optimizing a figure of merit that depends upon cost, efficiency, and spatial resolution. In a modular gamma camera comprising a tiled array of gamma detector modules, the performance figure of merit can be optimized by sparsely placing gamma detector modules within the gamma camera, optimizing collimation, and providing means for detector and/or collimator motion. Sparse gamma cameras can be constructed as flat or curved panels, and elliptical or circular rings.

  • Patent number: 10466369
    Abstract: An energy-resolved X-ray image detector includes a scintillation crystal layer, a photon detector layer and an optical layer. The scintillation crystal layer includes a plurality of scintillation crystals. The photon detector layer includes a plurality of photon detector elements. The optical layer is disposed between the scintillation crystal layer and the photon detector layer. The optical layer includes a plurality of optical elements having different light transmittances. The scintillation crystal is used for converting the X-ray beams into scintillation lights, and, when each scintillation light injects the corresponding optical elements, the light transmittances of the optical elements determine whether the scintillation lights can pass through the respective optical elements. The photon detection element then detects the scintillation lights passing through the corresponding optical elements to discriminate the energy of the X-ray beams.

  • Patent number: 10365384
    Abstract: A ray detector is disclosed, which includes a ray conversion layer for converting a ray incident on the ray detector into visible light, a photoelectric conversion layer for receiving the visible light and converting it into a charge signal, a pixel array having a plurality of pixels for detecting the charge signal, and a substrate below the photoelectric conversion layer, at least for directly or indirectly carrying the photoelectric conversion layer. The photoelectric conversion layer is made from a two-dimensional semiconductor material. Due to the high carrier mobility of the two-dimensional semiconductor material, it is possible to enable the external signal processing system to detect the charge signal more easily, so that a ray source with low energy can be used for ray detection. Therefore, a ray detector with high sensitivity can be provided, which may reduce the usage cost and be advantageous to saving energy.

  • Patent number: 10354437
    Abstract: Current real-time rendering techniques of virtual representations of jewelry with gemstones do not address the shimmer and sparkle of real gemstones. Embodiments of the present invention use real-time rendering methods and systems that enable flash scintillation and fiery scintillation on the facets of virtual representations of gemstones as they are manipulated online by the customer. A 3D representation of a gemstone is displayed. In response to user input corresponding to the manipulation of the displayed 3D representation of the gemstone, scintillations at facets of the 3D representation of the gemstone are determined. The scintillations are determined by loading a scintillation factor from a look-up table corresponding to an angle of incidence of a light source to a facet of the gemstone. The determined scintillations at the facets of the gemstone are displayed for the user in real-time.

  • Patent number: 10336465
    Abstract: Methods and systems for detecting ice crystals and volcanic ash in concentrations capable of causing power loss in aircraft jet engines. These hazard conditions are inferred from the detection of ice crystals or ash in air recently lifted from the lower atmosphere by convective updrafts. The detection systems can comprise subsystems for detecting air recently lifted from the lower troposphere by measuring radon activity along the aircrafts' flight track, as well as subsystems for detecting ice crystals or volcanic ash around the aircraft via multispectral measurements. The detection of ice crystals in air recently lifted from the lower troposphere indicates that the ice crystals are likely present in large concentration. The detection of volcanic ash in air recently lifted from lower atmosphere also indicates that volcanic ash is likely present in high concentration. These are hazards conditions that could cause power loss, jet engine flameout, and even damage jet engines.
