Abstract: One aspect of the disclosure provides a data acquisition system (“DAQ”) for monitoring, in parallel, the power consumption of a plurality of subsystems of a device under test (“DUT”). The DAQ comprises a plurality of power monitors and a field-programmable gate array (“FPGA”) chip. The power monitors are employed to gather the power consumption for the subsystems of the DUT. The FPGA chip can independently operate the power monitors via internal logic. By employing a parallel array of power monitors, power consumption data can be collected at the same time, and in some cases down to the tens of nanoseconds or less. Once the data is acquired by the FPGA chip, it timestamps, packages and sends the data to a host computer for further processing and/or presentation to a user.

Abstract: This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.
