  • Publication number: 20140034834
    Abstract: A mirror reflection processing method for a position sensitive detector device in intelligent bathroom products. The infrared emitter in the position sensitive detector device is provided with two infrared emitting intensity modes. The position sensitive detector device determines whether to consider that no signal is collected in current collection according to the result of comparison between the reflected infrared signal intensity received by the infrared receiver and the preset value therein, thereby overcoming the mis-operation of the position sensitive detector device when being opposite to objects with relatively high reflectivity, and making the position sensitive detector device even more widely applied.

  • Patent number: 8384032
    Abstract: A method for saving power consumption of a position sensitive detector used in a smart bathroom product includes changing infrared light emitting strength modes depending on the received strength of reflected infrared light. If the emitting mode is already the strongest, and the strength of the reflected infrared light received back from a reflecting object is weak, the method includes conducting multiple subsequent emissions and averaging the returns to estimate a distance to the infrared light reflecting object.

  • Publication number: 20100201276
    Abstract: The present invention discloses a method for saving power consumption of a position sensitive detector used in a smart bathroom product. An infrared light emitting device included in the position sensitive detector has infrared light emitting modes of at least two strengths. The position sensitive detector determines the emitting strength to be adopted by the infrared light emitting device at the time of next infrared light emission based on the comparison between the strength of the reflected infrared signal received by the infrared light receiving device and a preset value set in the position sensitive detector. Thus, by switching between different emitting strength modes, the infrared light emitting device is made to use an emitting mode with a weak strength in the case that no one is using the position sensitive detector, thereby effectively decreasing the power consumption of the position sensitive detector in its operation.
