Abstract: This application relates to a moisture ingress sensor. In particular, this application relates to a moisture ingress sensor that can detect liquid ingress into an electronic device. The moisture ingress sensor can include a resistor, an N-channel MOSFET, an operation amplifier, comparators, and an AND logic gate. The moisture ingress sensor is configured to provide a lower power means for accurately detecting moisture in an electronic device. Multiple areas of the electronic device can include the moisture ingress sensor in order to optimize the detection of moisture for at a variety of regions of the electronic device. Additionally, the electronic device can record signals from the moisture ingress sensor and shut down components of the electronic device that could be affected by the detected moisture. Furthermore, the moisture ingress sensor can be tuned to detect one or more types of liquids.

Abstract: Methods and apparatus for equalization of a high speed serial bus. Various aspects of the present disclosure are directed to a well-tuned passive equalization circuit for use with high frequency differential signals that 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.
