Claim 12:
13. A method, the method comprising:
receiving, by one or more analog inputs of a biopotential microchip, biopotential signals from a plurality of electrodes, at least one of the one or more analog inputs being coupled to a respective differential amplifier of the biopotential microchip, the differential amplifier being configured to amplify differences in signals between pairs of electrodes;
converting, by one or more analog-to-digital converters (ADCs) of the biopotential microchip, the biopotential signals to biopotential data;
obtaining and outputting, by an accelerometer disposed onboard the biopotential microchip, acceleration data indicating an acceleration of a portion of an arm of a user;
obtaining and outputting, by a gyroscope disposed onboard the biopotential microchip, angular rate data indicating an angular rate of the portion of the aim of the user; and
processing, by a processor of the biopotential microchip, the biopotential data outputted by the one or more ADCs, the acceleration data outputted by the accelerometer, and the angular rate data outputted by the gyroscope;
wherein the biopotential microchip is an integral unit and has all of the processor, the gyroscope, the accelerometer, the one or more analog inputs, the ADCs, located on a common unitary substrate,
wherein the biopotential microchip is configured to output, directly or indirectly, the biopotential data outputted by the one or more ADCs, the acceleration data outputted by the accelerometer, and the angular rate data outputted by the gyroscope, or derivatives thereof (collectively, data), to a classifier, the classifier being configured to generate, based on the data, an output indicating a parameter of the user,
wherein the biopotential microchip comprises either:
(a) a first low-power state in which the one or more ADCs and the differential amplifiers are not enabled but the accelerometer and the gyroscope are enabled; and an active state in which each of the one or more ADCs, the differential amplifiers, the accelerometer, and the gyroscope are enabled, or
(b) a second low-power state in which the accelerometer and the gyroscope are powered down but at least the one or more ADCs are active.
