  • Publication number: 20230236371
    Abstract: An optical transceiver sub-assembly (100) integrated with a silicon photonic platform having a folded optical path for transmitting and detecting a plurality of optical signals includes a housing chamber (105) and a top cover (110) to enclose elements of the optical transceiver sub-assembly (100) other than the housing chamber (105) and the top cover (110), a bottom housing module (115) accommodating an optical micro integration (130). In particular, the optical transceiver sub-assembly (100) is operably configured to establish an optical-electrical communication with an outside surrounding.

  • Patent number: 11546984
    Abstract: A PCB bridge for interconnection of two or more semiconductor chips for data communication between the semiconductor chips includes a plurality of metal strips; and a dielectric material disposed in between the plurality of metal strips. The PCB bridge is employed in a vertical direction in a semiconductor module for interconnection of two or more semiconductor chips, the vertical direction of the PCB bridge provides a flexible impedance matching by adjusting the dielectric material and a trace width of the PCB bridge, and the vertical direction of the PCB bridge avoids signal reflections by matching the impedance to a source, and a trace length of the PCB bridge is limited by spacing in between two semiconductor chips which further limited inductance of the trace of the PCB bridge.

  • Patent number: 10692995
    Abstract: The present invention provides an insulated-gate bipolar transistor (IGBT) structure and a method for manufacturing the same. The structure is a planar IGBT structure, and is characterized by an ultra-thin channel and buried oxide located below the channel. The structure can provide the theoretically lowest on-state voltage drop.

  • Patent number: 10691547
    Abstract: A system and method of performing backups of a system having persistent and non-persistent virtual desktop infrastructure components, database storage components, and file management components. The method first backs up the file management components, then a database server of the database storage components, and then the virtual desktop infrastructure components in an order of a virtual center server, connection server, and then a composer server. If the virtual desktop environment is non-persistent, the system backs up a master image that is used to create non-persistent desktops, and if the virtual desktop environment is persistent, the system backs up the master image that is used to create non-persistent desktops and virtual storage objects that maintain persistence of an identity of the virtual desktop environment.

  • Patent number: 10634618
    Abstract: The invention provides an apparatus for inspecting a light transmissible optical component. The apparatus comprises an image capturing module arranged on a first side of a support configured to hold a light transmissible optical component whilst it is being inspected. The apparatus includes an illumination device configured to shape light from a light source and to illuminate a selected portion of a surface of said light transmissible optical component with said shaped light to enable the image capturing module to capture any of a bright field image, a dark field image, or a combined bright field and dark field image of the light transmissible optical component being held by the support.
