  • Patent number: 11961770
    Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

  • Patent number: 9924906
    Abstract: A method and system for cancelling body movement effect for non-contact vital sign detection is described. The method begins with sending on a first electromagnetic wave transceiver a first electromagnetic signal with a first frequency to a first side of a body, such as a person or animal. Simultaneously using a second electromagnetic wave transceiver a second electromagnetic signal is sent with a second frequency to a second side of a body, wherein the first frequency and the second frequency are different frequencies. A first reflected electromagnetic signal reflected back in response to the first electromagnetic wave on the first transceiver is received and a first baseband complex signal is extracted. Likewise a second reflected electromagnetic signal reflected back in response to the second electromagnetic wave on the second transceiver is received and a second baseband complex signal is extracted.

  • Patent number: 9281590
    Abstract: An electrical connector includes an insulative housing having a longitudinal slot and at least one row of contacts retained in the housing. Each of the contacts defines a retention portion, a resilient contacting arm extending from the retention portion with a contacting portion protruding into the longitudinal slot, and a soldering tail extending out of the housing. The contacts include at least two differential pairs adjacent to each other and at least one grounding contact sandwiched therebetween in the longitudinal direction. The contacting portions of each differential pairs are closer to the mating face than the contacting portion of the grounding contact in the mating direction, which can improve resonance of the electrical connector during transferring high-speed signals.
