  • Patent number: 12388488
    Abstract: An automotive Ethernet physical-layer (PHY) transceiver includes an Analog Front End (AFE) and a digital processor. The AFE is coupled via a full-duplex Ethernet link to a peer transceiver. The AFE is configured to receive from the peer transceiver, over the full-duplex Ethernet link, an analog Ethernet signal conveying data symbols, at a reception data rate that is lower than a transmission data rate used in transmitting data from the PHY transceiver to the peer transceiver, the Ethernet signal being modulated by a spreading sequence having a Spreading Factor including a ratio between a spreading chip-rate and the reception data rate, and to convert the received analog Ethernet signal into a digital signal. The digital processor is configured to de-spread the digital signal using the spreading sequence to recover the data symbols.

  • Patent number: 9619808
    Abstract: A digital signage network employs a common data model and a subscription system to disseminate data gathered from a plurality of data sources to a number of displays. The network nodes interact with each other as content sources, content consumers, or both, with some systems acting as consumers to upstream sources and acting as sources to downstream consumers. The presentation of the data on a digital signage display allows for real-time binding of live data to provide a rich display effect.

  • Patent number: 9480487
    Abstract: A lateral light-emitting device for connecting a medullary guide wire is disclosed. The device comprises a closed main body, a front-end protecting unit for protecting the front end of the main body, and a connecting unit disposed at the distal end of the main body. The inside of the main body is further arranged with a lighting unit, a power supply unit, a light-scattering unit, a light intensity modulating unit, if necessary, and at least one transparent window. The device is able to fit to different types of medullary guide wires. The power supply unit provides power to the lighting unit to produce light emitted to the light-scattering unit and being diverted laterally through the transparent window of the main body after suitably modulating the light intensity. Thereby, the device is illuminated from within the bone cavity to allow observing the operating screw hole location from outside of the body and to enable precisely nailing while proceeding with the intra-medullary nailing procedure.

  • Patent number: 9323708
    Abstract: A computing and communication architecture utilizes a serial protocol based switched fabric among circuit cards housed in packaging arrangement. In one embodiment, each circuit card connected to the serial protocol based switched fabric in the packaging arrangement is provided with a protocol processor that enables all of the circuit cards to efficiently provide packet-based serial self-clocked communications at line speed. As a result, it is not necessary to arrange the circuit cards in a hierarchical manner in order to address the problems of switch blocking and related traffic congestion issues that would otherwise limit the implementation of the serial protocol based backplane arrangement for housing circuit cards.
