  • Sensor utilising overlapping signals and method thereof
    Patent number: 10489669
    Abstract: A device for detecting the location of an object within two or more at least partially overlapping sensing volumes of the device. The device is configured to illuminate the sensing volumes and generate a sensing signal individually for each sensing volume by sensing light modulated by any object in the sensing volume. Spatial encoding is applied to the sensing volumes. The device comprises a processor configured to determine the presence of an object in the sensing volumes based on the sensing signals generated for the sensing volumes and on the spatial encoding.
    Type: Grant
