Abstract
A device comprising: a sensor; and a first circuit configured to detect when an input stimulus to the sensor satisfies one or more detection criteria, and further configured to produce a signal upon detection that causes adjustment of performance of the device; and a second circuit for processing input following detection, wherein the second circuit is configured to increase its power level following detection, relative to a power level of the second circuit prior to detection.

One or more machine-readable hardware storage devices comprising instructions that are executable by a device to perform one or more operations comprising:
- detecting when an input stimulus to a sensor satisfies one or more detection criteria;
- producing a signal upon detection that causes adjustment of performance of the device by causing a circuit of the device to increase power level, relative to a power level of the circuit prior to detection;
- and
- processing input to the device using the circuit with the increased power level.
A method performed by a device, comprising:
- detecting when an input stimulus to a sensor of a device satisfies one or more detection criteria;
- producing a signal upon detection that causes adjustment of performance of the device by causing a circuit of the device to increase power level, relative to a power level of the circuit prior to detection;
- and
- processing input to the device using the circuit with the increased power level.
A device comprising:
- an acoustic transducer;
- and
- a first circuit banded over a frequency range and configured to detect when (i) an acoustic level of the acoustic transducer exceeds a threshold level, or (ii) when an average banded acoustic level for the acoustic transducer for a period of time exceeds the threshold level and is further configured to produce a first signal;
- wherein the first circuit is in a power mode that consumes less than 350 microwatts.
