A liquid dispensing device, in particular for hospitals and clinics, whereby the supply of hot or cold water to a wash bowl or the like may be controlled without touching any valves by hand. The water supply is regulated by an electromagnetic valve controlled by a proximity detector operating as a variable voltage divider. The proximity detector is fed with a high frequency signal and delivers an output voltage which may be influenced by putting the hand near the proximity detector. Separate proximity detectors for controlling the supply of hot and cold water, respectively, are mounted on the outlet pipe of the wash bowl in such manner that they may be actuated either separately or simultaneously, so that hot, cold or tepid water may be supplied as desired.
A water faucet is disclosed that is automatically turned on and off in response to the proximity of the user's hand or other object to the faucet. An ultrasonic transducer is located in the faucet near the water outlet and transmits bursts of ultrasonic waves. When a wave reflects off a user's hand and creates an echo signal, the echo is detected by the ultrasonic transducer. Circuitry connected to the ultrasonic transducer determines when an object is within a predetermined distance of the faucet by measuring the time elapsed between the transmission of the burst and the reception of the echo. Once an object is within this predetermined distance, the circuitry causes a valve to open and water is supplied by the faucet.

Once an object is within this predetermined distance, the circuitry causes a valve to open and water is supplied by the faucet. Additionally, there is an embodiment wherein the level to which the receptacle is to be filled can be selected by the user and the fill system automatically fills the receptacle to that level. Further, there is a drain control system disclosed that causes fluid to be removed from the receptacle if the user selects an empty level or a fluid level that is lower than the fluid level of the fluid currently within the receptacle. Still further, there is a receptacle having a pilot well in communication with the main portion of the receptacle. The distance measuring sensor can be placed within the pilot well so that the rim of the receptacle exposed to the user is unencumbered.
An automatically operating valve for regulating water flow, especially a mixing valve for automatically mixing hot water and cold water to obtain a mixed water of a desired temperature is characterized by employing piezoelectric actuators for operating valve bodies thereof. Due to such a construction, the valve can not only fully close or open but also carries out the fine flow amount control by regulating the opening rate or angle of the valve body. Especially in case the automatically operating valve is a mixing valve, the mixing ratio of hot water and cold water can be accurately regulated so that the mixed water of a desired temperature can be always automatically obtained.
An electronically operated assembly to be used in conjunction with water faucets is provided with a sensor that senses the presence of objects such as human hands and automatically starts the flow of water. The water flow automatically stops when the object is removed from the faucet vicinity. An electronically automated assembly for water faucets comprises a water flow control valve and a small size electric motor adapted to operate the water flow control valve via a transmission gear and an infrared sensing device connected to a source of electric power adapted to activate or disconnect the electric motor.
Apparatus for continuous sensing of hand and arm gestures comprises hand-held means for continuously sensing at least tempo and emphasis. These sensed parameters are represented quantitatively, and transduced by appropriate circuitry into electrical signals indicative of the parameter quantities. The signals may be used to control the performance of a musical composition (or the evolution of some other dynamic system), or may instead convey information. The signals may, for example, be provided to an interpreter that dynamically infers control commands from the gestures on a real-time basis in accordance with the generally accepted canon of musical conducting, directing the controlled system in accordance therewith. The invention may also sense one or more additional conducting parameters such as the speed and/or velocity, direction (i.e., trajectory) in three dimensions, absolute three-dimensional position, the “size” of a gesture in terms of the spatial distance between successive beats, and the “placement” of a beat pattern in space.
The fluid supply apparatus supplies and controls one or more fluids while adjusting/controlling one or more continuously parameters; and includes an outlet, at least one control valve and a touchless user control interface. For example a faucet has sensors mounted thereon to control water flow (6) and temperature (16, 17). For example a user hand in field (16) will increase temperature over time and decrease in field (17). The on/off sensor field may include the water stream, a bi-colour light emitting diode indicates temperature, temperature feedback means maintains the desired temperature, a battery or super capacitor allows operation or fluid shut off if power fails, an anti-tamper feature requires the fluid to be shut off if more than one sensor is covered and a time prevents waster wastage. The hygienic touchless interface may be in a tile or flat plate. Other applications may include panel mounted fluid control systems for controlling a plurality of fluid types and associated parameters.
PURPOSE: To regularly and certainly operate a device without a possibility of improper operation by a foreign material by providing first to third opening and closing means for opening and closing a solenoid valve, depending on the distance detected by a distance sensor in a valve control means. CONSTITUTION: When a user goes in front of a sink 14 and reaches out his hand just before a distance sensor 21 (a position closer to the sensor 21 than a first distance), a first opening and closing means 1 operates to open a solenoid valve 13, so that water or hot water is released from a faucet 12. When the user again reaches out the hand just before the sensor 21, a second opening and closing means 2 operates to close the valve 13. The valve 13 is alternately opened and closed every time when the hand is consciously reached out just before the sensor 21, and the release and stop of water from the faucet 12 are repeated. When the user leaves the sink 14 during release of water, a third opening and closing means 3 operates to close the valve 13, so that the release of water is stopped. When a foreign material passes just before the sensor 21 in the absence of the user, the means 1 detects this to open the valve 13, but after the foreign material passed, the means 3 operates to close the valve 13.
PURPOSE: To make it possible to inject water at the position of a hand with accuracy by laying out a sensor which detects light at the tip of an arm member which follows a rotary movement of a faucet and bringing a hand near a water outlet so as to pass water and separating the hand from the outlet so as to stop the flow of water. CONSTITUTION: The length dimensions of a faucet 12 and an optical detection sensor 20 are arranged with an optical detection member 19 by expanding and contracting the arm. The arm member 19 is turned, centering on a mounting shaft 22 of the arm member 19. The positional arrangement of the sensor 20 is made so as to set that the sensor come to the tip of the faucet 12. As descried above, fingers are held out to the tip of the faucet 12 on a washstand. When the sensor 20 detects this, a faucet drive mechanism 15 makes a closing motion so that tap water may flow out from a water outlet 13. Then, the fingers are pulled in after cleaning and the faucet drive mechanism 15 makes a closing motion by way of the sensor 20, thereby halting the flow of water. When the faucet 12 is interrupting, the faucet 12 is turned to a corner, thereby securing an upper space. The faucet 12 and the optical detection sensor 20 are turned in one piece motion by mounting a connection member 2 and both members 12 and 20 may be independently turnable respectively.
PROBLEM TO BE SOLVED: To provide a water supply control device, enabling reduction of wrong sensing due to detection of others than the hand and detection of the hand during washing work during the operation of a rotary handle or a lever handle of a water faucet and to provide a water supply control device, preventing an increase in size of a top part of a spout, not impairing the appearance of the spout, and having good design. SOLUTION: This water supply control device has a capacitance detecting type sensor used as a detecting part having a human body detecting means, and includes an opening and closing valve unit for opening and closing a passage according to the input from the detecting part, a controller for controlling the opening and closing valve unit, and a discharge part for discharging liquid supplied by the opening and closing valve unit. As a detecting means of the capacitance detecting type sensor, a detecting electrode is exposed on the detecting surface.
PROBLEM TO BE SOLVED: To provide an automatic water-discharge controller capable of making precise water-discharge control by corresponding to the movement such as a forward movement of a hand to the water-discharge controller, a hand washing and a backward movement of the hand or the like of a user in the water discharge controller making use of an object sensor. SOLUTION: When water is not discharged, the first electromagnetic wave beam 23 is emitted to the first direction facilitating the detection of the forward movement of the hand 10 from a microwave motion-body sensor 22. When the forward movement of the hand 10 is detected by the first electromagnetic wave 23, the water discharge starts and, at the same time, the second electromagnetic wave beam 31 is emitted to the second direction facilitating the detection of the movement of scattering water 34 during the hand washing and having difficulty in making detection of a stream 30 naturally flowing out from a faucet 21. When the movement of the scattering water 34 can't be detected by the second electromagnetic wave beam 31, the water discharge stops.
A faucet control system comprises a valve apparatus, sensors or a touch panel to be activated by a user, and a controller that controls the valve apparatus. A first sensor may start fluid flow and a second sensor may alter the proportion of fluids delivered from two fluid sources. The sensors may be activated without being touched and may include infrared sensing elements. The touch panel may be activated with hand pressure and may include electrically conductive sheets. The touch panel may have a first portion for allowing fluid flow from a first fluid source, a second portion for allowing fluid flow from the first fluid source and a second fluid source, and a third portion for allowing fluid flow from the second fluid source. The controller may include an adjustable timer so that fluid flow can be stopped automatically after a selected period of time.
