  • Publication number: 20140370750
    Abstract: An apparatus is described herein. The apparatus includes a receptacle to receive a plug to couple a peripheral device to a computing device. The apparatus includes a ground contact of a printed circuit board of the computing device. The apparatus includes a shield communicatively coupled to the ground contact, wherein the shield is to reduce radio frequency interference (RFI) from an interface between the plug and the receptacle.

  • Publication number: 20140218132
    Abstract: A system, hybrid common mode choke, and method are described herein. The system includes a differential signal transmitter and a differential signal receiver. A differential signal transmitter ground and a differential signal receiver ground are electrically disconnected in a manner that enables a common mode filter. The transmitter ground and the receiver ground may be coupled using an inductor, a resistor, a capacitor, or any combination thereof.

  • Publication number: 20140153656
    Abstract: Methods and systems may provide for generating a data signal based on a local clock signal and converting the local clock signal into a pseudorandom binary sequence (PRBS) signal. The data signal and the PRBS signal may be transferred from a transmitter to a receiver via a channel, wherein a recovered clock signal may be generated at the receiver based on the PRBS signal. Additionally, the data signal may be processed based on the recovered clock signal. In one example, the PRBS signal has a number of timing edges that is randomized and less than a number of timing edges in the local clock signal per period of time.

  • Publication number: 20140002305
    Abstract: A patch-based proximity sensor having a capacitance and/or inductance that varies based on a proximity of an animate body, a sense circuit to sense the capacitance and/or inductance, and a control system to compare one or more sensed values to one or more thresholds, and to selectively enable/disable one or more antennas based on the comparison(s). The threshold may correspond to a desired/permitted minimum distance between an antenna and an animate body, and/or a desired/permitted maximum electromagnetic energy exposure to the animate body. A multi-layer module may include one or more patch-based proximity sensors and one or more patch-antennas. Multiple antennas may be individually controllable based on corresponding proximity measures.

  • Publication number: 20130271909
    Abstract: Multi-pair differential lines printed circuit board common mode filters are generally described. In one embodiment, the apparatus includes a multi-layer printed circuit board, a first signal line and a second signal line forming a first differential pair on a first layer of the printed circuit board, a second differential pair on the first layer of the printed circuit board, and a common mode filter on a second layer of the printed circuit board, the common mode filter comprising an absence of a predominantly occurring dielectric material of the printed circuit board, the common mode filter spanning an area directly below at least a portion of both the first and the second differential pairs. Other embodiments are also described and claimed.
