  • Publication number: 20120289338
    Abstract: A gaming system is disclosed comprising a console unit having a processor and transceiver circuitry. The transceiver circuitry couples to the processor and includes respective receiver and transmitter circuits. A first phased array antenna interface is employed to transmit and receive directional signals in response to the processor. The system employs a mobile game controller including a second phased array antenna interface to receive and redirect the directional signals back to the first phased array antenna interface. The processor generates proximity data based at least in part on a parameter associated with the directional signals, the proximity data representing the proximity of the mobile game controller with respect to the game console unit.

  • Patent number: 8153387
    Abstract: A method for immobilizing glycoprotein is disclosed. A surface is provided. Next, a boronic acid is contacted to the surface. The boronic acid is represented as Y—R—B—(OH)2 and includes a boronic acid group (B—(OH)2), a linker R, and a functional group Y, in which the boronic acid is bonded to the surface via the functional group Y. A glycoprotein is contacted to the boronic acid, wherein two spatially adjacent hydroxyl groups of a carbohydrate chain form a boronate ester with the boronic acid group of the boronic acid to immobilize the glycoprotein. The goal of site-specific and covalent protein immobilization without interfering the binding affinity of an antibody to antigen may be thus achieved with the reaction of boronic acid and the carbohydrate chain of Fc region.

  • Publication number: 20090104396
    Abstract: A color pattern film for metal shell is provided. The color pattern film for metal shell includes a transparent polymer substrate, a releasing coating layer, a protective layer, an ink layer, and an adhesive layer. The releasing coating layer is on the transparent polymer substrate, the protective layer is on the releasing coating layer, the ink layer is on the protective layer, and the adhesive layer is on the ink layer. The adhesive layer at least includes a base resin which is one of resin systems selected from ethylene-vinyl acetate (EVA), polyester (PET) resin, and polyolefin resin. The color pattern film for metal shell can be directly pressed and attached onto a metal sheet or coil, and subsequently punched, thus the problems of the prior art that the yield of adhesive wet film coating process is not easily controlled and complex post-processes are still required after molding are addressed.

  • Patent number: 6697260
    Abstract: An integrated high-speed package comprising a package housing having a housing lip and connector having a center pin abutting along a bottom surface of the housing lip. For signal registration of a first substrate to the signal lead, the substrate is “floated” up to the housing lip, which provides an alignment reference to ensure that the top surface of the first substrate is aligned and in direct registration with the signal lead. In another embodiment, the center pin to substrate registration is provided at a top surface of a housing base. The housing base preferably comprises a first portion of a first height and a second portion of a second height. Accordingly, the housing base can accommodate substrates of different thickness while allowing a top surface of the first and a second substrate to be coplanar to facilitate signal registration there between.

  • Patent number: 6548893
    Abstract: An apparatus and method for hermetically sealing, EMI shielding integrated circuits for high-speed electronic devices using a combination of microstrip to buried stripline interface for signal transmission from the integrated circuit. The packaging provided comprises a first plurality of microstrips interconnecting the integrated circuit to a plurality of buried striplines exposed on a surface of the main substrate. A ceramic interposer placed over the main substrate “buries” a portion of the exposed striplines on the main substrate to thereby insulate these signal paths from a hermetically sealing, and EMI shielding metal lid placed over the integrated circuit. The metal lid and the seal ring brazed over the ceramic interposer thus provide both a hermetic seal and an electric radiation block. A reduction in dispersion due to the buried striplines is also achieved, as well as improving jitter performance.
