Abstract

The invention presents an automatic water feed method in lavatory using artificial retina sensor and an automatic water feed mechanism in lavatory using artificial retina sensor which detects the user of the lavatory securely.

The invention controls a water feed operation of a lavatory such as flush urinal and hand washer by visually recognizing the user of the lavatory by means of an artificial retina sensor.

Claims

1. An automatic water feed method in lavatory using artificial retina sensor characterized by being configured to control the water feed operation of a lavatory such as flush urinal and hand washer by visually recognizing the user of the lavatory by means of an artificial retina sensor.

2. An automatic water feed method in lavatory using artificial retina sensor characterized by being configured to control the water feed operation of a lavatory such as flush urinal and hand washer by visually recognizing the user of the lavatory by means of an artificial retina sensor, and further to limit the viewing field region of the artificial retina sensor only in the region of water discharge from the lavatory.

3. An automatic water feed mechanism in lavatory using the artificial retina sensor characterized by comprising a lavatory such as flush urinal or hand washer, an artificial retina sensor for visually recognizing the user of the lavatory, and a control unit for controlling water feed operation of the lavatory on the basis of the output from the artificial retina sensor.

4. An automatic water feed mechanism in lavatory using the artificial retina sensor characterized by comprising a lavatory such as flush urinal or hand washer, an artificial retina sensor for visually recognizing the user of the lavatory, and a control unit for controlling water feed operation of the lavatory on the basis of the output from the artificial retina sensor, in which the viewing field region of the artificial retina sensor is limited to include only the region of water discharge from the lavatory.

5. An automatic water feed method in lavatory using the artificial retina sensor characterized by comprising a lavatory such as flush urinal or hand washer, an artificial retina sensor for visually recognizing the user of the lavatory, and a control unit for controlling water feed operation of the lavatory on the basis of the output from the artificial retina sensor, in which a plurality of artificial retina sensors are provided in order to recognize the user visually together with a perspective sense.

6. An automatic water feed mechanism in lavatory using the artificial retina sensor characterized by comprising a lavatory such as flush urinal or hand washer, an artificial retina sensor for visually recognizing the user of the lavatory, and a control unit for controlling water feed operation of the lavatory on the basis of the output from the artificial retina sensor, in which a plurality of artificial retina sensors are provided in order to recognize the user visually together with a perspective sense.
