Abstract: Methods and apparatus for equalization of a high speed serial bus. A well-tuned passive equalization circuit for use with high frequency differential signals suffer from e.g., impedance mismatches, impedance discontinuities (e.g., connectors, etc.). In one embodiment, a shunting circuit is inserted between the differential terminals of a Universal Serial Bus (USB) cable, connector, etc. The shunting circuit is configured to “open” at low frequencies to enable Full Speed (FS) enumeration, while also providing sufficiently high impedance at high frequencies to enable High Speed (HS) operation. In one such implementation, the shunting circuit includes a tuned resistor, capacitor, inductor, and switch element arranged in series.

Abstract: A docking station configured to mate to an electronic device enables methods of interacting with the electronic device by impacting (e.g., knocking) on a table on which the device and/or the docking station are disposed and by means of contactless gestures. The electronic device may remain in a powered off state while the docking station continuously monitors for user input. The docking station may have a processor that is capable of detecting a user's impact and contactless gesture inputs.
