20150026880 | DRAIN DEVICE AND ELECTRONIC CONTROL TYPE DRAIN SYSTEM - A drain device includes a tube set, a transmission, a stopper and a driver. The transmission is disposed in a main tube and an isolating inner tube, and extended from the front end of the isolating inner tube to the front end of the main tube. The stopper is mounted to a front end of the transmission, and adapted to close or open a water feeding inlet. The driver is disposed in the isolating inner tube, and mechanically connected to the transmission, whereby after the driver receives an electronic control signal, the driver drives the stopper to move downward or upward via the transmission, and there is a sealing effect or a gap between the stopper and the annular plate. | 01-29-2015 |
20150040311 | GREY WATER INTERFACE VALVE LIQUID LEVEL SENSOR SYSTEM - Embodiments of the present disclosure generally provide a grey water interface valve liquid level sensor system. The liquid level sensor system may deliver information about the water level and the water movement that occurs in a water reservoir. A control unit may then activate a valve to open so that the water can be removed via vacuum. | 02-12-2015 |
20150101121 | Faucet System Comprising a Liquid Soap Delivery Line - A water faucet system including a faucet having a neck comprising a water passageway and liquid soap delivery line, both integrated within the neck assembly. The water faucet system features a streamlined neck assembly that includes a water outlet or spout, located at the distal portion of the neck assembly, and additionally includes a separate soap outlet located at a predetermined location. The soap delivery (soap dispensing) is initiated by a user performing an activation event directed to a sensor system located in the neck assembly. In preferred embodiments, the sensor system utilizes touchless type sensors so to avoid any physical contact with the neck assembly. | 04-16-2015 |
20150299992 | HUMAN BODY DETECTION SENSOR AND AUTOMATIC FAUCET - A human body detection sensor includes: a detection decision unit that decides whether a state is a detection state or a non-detection state of a detection target; a specular reflection decision unit that decides whether or not reflected light that is incident onto a line sensor is specularly-reflected light; and a continuation decision unit that decides whether or not a state in which the detection target exists is ongoing, wherein, when specularly-reflected light is detected while a determination is made indicating the detection state, the detection decision unit keeps the result of a determination indicating the detection state without change if the result of the decision by the continuation decision unit indicates that the state is ongoing and changes the determination to a determination indicating the non-detection state if the result of the decision shows any other states. | 10-22-2015 |
20150376880 | TOUCH FREE AUTOMATIC FAUCET - A touch free automatic faucet is provided. The faucet includes a faucet housing including many sensors for controlling water flow and water temperature. A processor is connected to the sensors. A first control valve assembly is connected to the processor. A second control valve assembly is connected to the processor. A power source is connected to the processor, the first control valve assembly and the second control valve assembly. Water flow and water temperature are controlled by the sensors without touching of the faucet housing. | 12-31-2015 |
20160024766 | FAUCET INCLUDING CAPACITIVE AND ULTRASONIC SENSING - A fluid delivery apparatus includes a spout, an ultrasonic sensor, and a capacitive sensor. The ultrasonic sensor is configured to detect the presence of a user adjacent the spout when enabled. The capacitive sensor is configured to define a capacitance sensing field in an area near the spout and also to detect a presence of a user. A controller is coupled to the capacitive sensor and the ultrasonic sensor. The controller is programmed to detect the presence of a user in the capacitance sensing field based on an output signal from the capacitance sensor. The controller is also programmed to enable the ultrasonic sensor in response to detecting the presence of the user in the capacitance sensing field with the capacitive sensor, thereby reducing the amount of power used by the ultrasonic sensor. | 01-28-2016 |
20160024767 | SENSOR FAUCET AND INFRARED SENSOR THEREOF - An infrared sensor includes a first emitting module, a second emitting module, and a receiving module. The first emitting module includes a first emitter and a first lens; the second emitting module includes a second emitter and a second lens. The first emitter and the second emitter respectively emit an infrared ray along an optical axis, wherein an acute angle is formed between the optical axes. The receiving module is located between the first emitting module and the second emitting module, wherein the receiving module includes a receiver and a third lens. The infrared rays emitted from the first and the second emitter respectively pass through the first and the second lens, afterwards, the infrared rays are reflected to pass through the third lens, and thus received by the receiver. Additionally, the infrared sensor may be applied to a sensor faucet for controlling a water valve in the sensor faucet. | 01-28-2016 |
