  • Patent number: 11308788
    Abstract: A wearable computing device may be used to track the efficacy of one or more cleaning actions performed. The device can include one or more sensors that detect and measure motion associated with a cleaning event. In different examples, the movement data generated by the device can be compared to reference movement data to determine if the individual has cleaned all the objects they were expected to clean and/or if the individual has cleaned a given object sufficiently well. As another example, the movement data generated by the device can be analyzed to distinguish cleaning and non-cleaning movement actions as well as to distinguish different types of cleaning actions during cleaning movement. The quality of each cleaning action can be evaluated. In any configuration, the device may perform an operation in response to determining that ineffective cleaning is being performed, causing corrected cleaning action to be performed.

  • Patent number: 11009996
    Abstract: An optical proximity sensor with a digital calibration circuit and a digital calibration method are provided. In a test mode, a test light emitted by a light transmitter is reflected by a cover of an electronic device to form a first reflected analog signal to a light receiver. A digital calibration circuit counts the first number of pulse waves of a first reflected digital signal. In a calibration mode, a light is emitted to a detected object through the cover and then is reflected by the detected object to form a second reflected analog signal to the light receiver. When the digital calibration circuit counts the number of pulse waves of a second reflected digital signal up to the first number, the digital calibration circuit clears the first number and then recounts the number of pulse waves of the second reflected digital signal to obtain the second number.

The directivity setting device is configured to direct a radio wave being emitted from the radio wave emitting port (27), in such a manner that, during a water stopping state, the emitted radio wave lies along a spouting direction (A) along which washing water is to be spouted from a spout port (26), and, during a water spouting state, a part of the radio wave emitted disposed offset in a direction C, with respect to the spout port (26) interferes with a region of a peripheral surface of a stream (W) facing in the direction C.

  • Patent number: 8955822
    Abstract: The present invention is directed to novel optical sensors and novel methods for sensing optical radiation. The novel optical sensors and the novel optical sensing methods are used, for example, for controlling the operation of automatic faucets and flushers. The novel sensors and flow controllers (including control electronics and valves) require only small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. A passive optical sensor includes a light detector sensitive to ambient (room) light for controlling the operation of automatic faucets or automatic bathroom flushers.

  • Patent number: 8950019
    Abstract: A lavatory system is disclosed including one or more integrated hand washing stations. Each hand washing station includes a basin, a faucet, a solenoid valve configured to control water flow to the faucet, and an electric hand dryer located adjacent the basin and the faucet so that the user of the washing station may use the faucet and the electric hand dryer without leaving the washing station. The electric hand dryer preferably includes an outlet to direct air across the associated basin so that any water that drips from the user's hands fall within the basin. A control system may be provided to control activation of the fixtures such as the solenoid valve, the electric hand dryer, and/or soap dispenser. The control system may be configured to inhibit simultaneous activation of the solenoid valve and the hand dryer. A photovoltaic system may be provided to provide power.

  • Patent number: RE48951
    Abstract: A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. Each compliance badge receives dispense event signals corresponding dispenser identification information associated with dispense events initiated by the wearer of the compliance badge. The badges store dispense event records associated with each dispense event initiated by the wearer and thus keep track of all dispense events initiated by the wearer of the compliance badge.
