Visual sensor to recognize cap on/off using unique pattern
A recently granted patent (Publication Number: US11892747B2) discloses a visual sensor designed to be capped with a cap containing at least one light-transmitting part with an opening. The sensor includes a light-sensitive element that outputs a pixel map and a processor that determines if the pixel map matches a predetermined pattern by comparing characteristics. Depending on the match, the sensor determines if it is capped or not and takes actions accordingly, such as issuing alerts to the user. The cap's light-transmitting part can have varying sizes and transparency values, enhancing the sensor's functionality and adaptability.
Furthermore, the patent describes variations of the visual sensor, including one with a cap containing a radiating element facing the sensor's lens when capped. This design allows for the sensor to detect if it is capped based on the pixel map output by the light-sensitive element. The sensor can also include a power source and wiring for the radiating element, ensuring seamless operation. Additionally, the sensor can be configured with a reflector on the cap, further enhancing its capabilities. These innovative features make the visual sensor versatile and efficient in various applications, providing a unique solution in the field of sensor technology.
