20120174306 | AUTOMATIC SENSING SYSTEM AND METHOD FOR USE WITH A PLUMBING FIXTURE - An automatic sensing system and a detecting method for use with plumbing equipment in the kitchen and washroom are shown and described. The automatic sensing system includes an ambient light sensor for detecting the ambient light intensity around the equipment. The system further includes a detecting sensor for detecting whether user enters the detected area. The system also includes a controller which controls the equipment based on detected signals from the detecting sensor. The controller is configured to start or change the state of the detecting sensor according to a detected value change of the ambient light intensity. The automatic sensing system advantageously saves power consumed by the detecting sensor when the ambient light sensor does not indicate use by the equipment. | 07-12-2012 |

20130160199 | BATHTUB HAVING MASSAGE FEATURES - The present invention application provides a bathtub. On the bathtub wall are fixed ultrasonic transmitters, and an ultrasonic transducer drive circuit is electrically connected to ultrasonic transducers. The ultrasonic transmitters further include an ultrasonic divergent structure which, after reflecting and scattering the ultrasonic waves emitted by the ultrasonic transducers, transmits the same into the bathtub (e.g., into the water of the tub). | 06-27-2013 |
20130307562 | SYSTEMS AND METHODS FOR FFT-BASED MICROWAVE DISTANCE SENSING FOR A PLUMBING FIXTURE - Systems and methods for detecting a position of an object relative to a plumbing fixture are provided. A described method includes emitting a microwave detection signal toward a moving object, receiving an echo-wave signal reflected from the moving object, and superimposing the microwave detection signal and the echo-wave signal to produce a superimposed time domain signal. The method further includes performing a Fast Fourier Transformation on the time domain signal to generate a frequency domain signal, integrating the frequency domain signal, and actively adjusting a result of the integration by subtracting a predetermined amount from the result. The predetermined amount is at least one of: a volume contribution amount and an interference contribution amount. The method further includes determining a position of the moving object relative to the plumbing fixture by comparing the adjusted integration result with a distance standard curve. | 11-21-2013 |
20130307669 | SYSTEMS AND METHODS FOR PAIRING A WIRELESS TRANSCEIVER UNIT FOR SANITARY WARE - Systems and methods for pairing a wireless transceiver unit for sanitary ware are provided. An exemplary pairing method includes emitting a pairing instruction signal from a wireless sender of the wireless transceiver unit, receiving the emitted pairing instruction signal at one or more wireless receivers, and detecting a signal intensity of the pairing instruction signal received at each of the one or more wireless receivers.
