One of the most common uses for photocells is turning exterior lights on at sunset and off at dawn. Because they sense ambient light levels, photocells automatically adjust to seasonal changes in the day/night cycle and are unaffected by daylight-saving time. Photocells controlling exterior light...
Having motion detectors installed on your property can help you lower your energy bills. You will not have to leave your exterior lighting on during the day and night. Motion detectors will activate and deactivate your lights automatically, helping to reduce energy consumption in the home. Motion ...
Place motion-sensing flood lights outside just under your eaves or near a garage door for added security. You might also consider positioning outdoor lights with motion sensors along pathways to help you see better in the dark. If you want night lights for outdoor walkways, look for solar ...

The field of the invention is mechanical motion detectors, and particularly, mechanical means for indicating the rotation of a shaft. Mechanical motion detectors such as that disclosed in U.S. Pat. No. 3,573,405 include a fluid pump which is connected to a shaft and which includes an electr...
Lighting fixtures that are activated by passive infra-red (PIR) motion detectors have long been available. PIR motion detectors were first used in the lighting field with utilitarian lighting such as flood lights or other area lighting. These early models employed assemblies of germanium lenses or ...
Pose of a pedestrian, which may be used to determine a predicted trajectory and/or current trajectory, may be used in conjunction with sensors or detectors for operating or navigating an autonomous vehicle (herein after, “vehicle”). For example, information from a sensor system on board a ve...
A wristband and/or a mobile gaming device may include sensors, cameras, microphones, or other detectors for detecting the output of the emitters. For example, a wristband may include a camera. The camera may detect light from emitters on a gaming device. Based on the position of the emitters...
The gaming device may include detectors, such as cameras, microphones, or antennas. The gaming device may determine the positions or relative positions of emitters on a wristband. For example, in a normal upright position, two emitters on a wristband may appear side by side. When the wristband...
The smart home environment 100 may additionally or alternatively include one or more other occupancy sensors (e.g., the smart doorbell 106, smart door locks 120, touch screens, IR sensors, microphones, ambient light sensors, motion detectors, smart nightlights 170, etc.). In some implementations...
