USE OF OPTICAL REFLECTANCE PROXIMITY DETECTOR IN BATTERY-POWERED DEVICES

摘要

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.

主权项

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 an object 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 object within the distance of the proximity detector, wherein:
the object is not actively self-illuminated; andthe 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.
