  • Patent number: 10004125
    Abstract: A path light control device that can include a processor and light source, and any combination of ambient light sensors (ALS), passive infrared (PIR) sensors, accelerometers and compass sensors, where the sensor sampling mode and sampling period may be dynamically determined to permit the ALS to accurately measure an ambient light without excessive operation. The accelerometer and compass sensor may be provided to determine device movement and orientation to avoid sensor operation when movement or orientation of the device indicates that the data of the sensor is not applicable for proper device control.
    Type: Grant
