Use of optical reflectance proximity detector in battery-powered devices
First Claim
1. A battery-powered device, comprising:
- test circuitry that performs a test on an aspect of the battery-powered device; and
a proximity detector that;
monitors for a hand being physically waved in a wave movement within a distance of the proximity detector; and
generates a proximity detection signal when the proximity detector detects the wave movement of the hand within the distance of the proximity detector, whereinthe proximity detection signal generated by the proximity detector causes an indication to be output by the battery-powered device based on the test performed by the test circuitry.

Abstract
Various methods, systems, and devices for identifying a condition of a battery-powered device are presented. For example, a device may include a smoke detection sensor that detect smokes and, in response to detecting smoke, generate a smoke detection signal. The device may include test circuitry that tests an aspect of the battery-powered device. The device may include an audio output device that outputs a sound in response to the test circuitry determining a particular condition is present. The device may include a proximity detector that monitors for a wave movement of an object within a distance of the battery-powered device and generates a proximity detection signal when the proximity detector detects the wave movement performed by the object within the distance of the smoke detector device.
