    摘要: A method according to one embodiment identifying the frequency range of at least one active channel of at least one wireless communication RF band; identifying the frequency range of at least one clock harmonic; identifying an overlap, in whole or in part, between the frequency range of the at least one active channel and the frequency range of the at least one clock harmonic; and shifting a fundamental frequency of the at least one clock to shift the frequency range of the at least one clock harmonic out of, at least in part, the frequency range of the at least one active channel. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

    摘要: Provided herein are different embodiments for performing radio frequency interference (RFI) mitigation in electronic devices such as mobile computing systems. In some embodiments, a dynamic RFI mitigation scheme allows for monitoring of wireless channels for RFI and to adaptively shift an identified RFI source (e.g., system clock) harmonics, e.g., either out of the on-channels or to a neutral position within the on-channels such as by using cost-function analysis.

    摘要: An apparatus may include a radio interface to receive a plurality of signal strength values of a radio. An interference module can identify a radio frequency interference impact on the radio based on the plurality of signal strength values. In one embodiment, the radio interface issues a plurality of interference calls to the radio, where each of the plurality of signal strength values corresponds to an interference call.

    摘要: A first apparatus includes a semiconductor device and a heatsink thermally coupled to the semiconductor device. The heatsink is located and formed to screen the device from external electromagnetic radiation or to contain radiation produced by the device. A second apparatus includes a semiconductor device, a heatsink thermally coupled to the semiconductor device, and a grounding structure having a capacitive coupling to the heatsink.
