Abstract: A capacitance sensing type water supply device includes a metal shell, a capacitance sensor, an electronic control unit and a fluid control unit. There is a capacitive effect between an external object and the metal shell when a distance between the external object and the metal shell is within a first distance range or a second distance range, whereby a corresponding electric value is generated by the metal shell. The capacitance sensor senses the electric value of the metal shell, and then provides the electronic control unit with a corresponding sensing signal, whereby the electronic control unit controls the fluid control unit to drive whether the water of water supply device is supplied, whether the water of water supply device is supplied continuously, whether the flow rate of supplied water of water supply device is changed and whether the temperature of supplied water of water supply device is changed.

Abstract: A two-distance touch free automatic type water supply method includes: when a sensor senses an appearance of an external object at a first distance from the sensor, the sensing signal is an open signal, whereby water of the outlet is supplied; when the sensor senses a disappearance of the external object at the first distance from the sensor, the sensing signal is a closed signal, whereby water of the outlet is not supplied; when the sensor senses a first appearance and a first disappearance of the external object at a second distance from the sensor, the sensing signal is an open signal, whereby water of the outlet is supplied; and when the sensor senses a second appearance and a second disappearance of the external object at the second distance from the sensor, the sensing signal is a closed signal, whereby water of the outlet is not supplied.

Abstract: A touch free automatic type water supply device is adapted to be installed at a faucet. The faucet includes an outlet. The touch free automatic type water supply device includes: a shell including an inlet, a flow channel and an outlet, wherein the inlet of the shell is adapted to be communicated with the outlet of the faucet; a control circuit adapted to sense an external object and then to generate a control signal; and a driving unit, whose an end is disposed in the shell, and is physically connected to an end of the flow channel, wherein the driving unit is electrically connected to the control circuit for controlling water flow rate of the outlet or automatically switching on/off water supply of the outlet according to the control signal.

Abstract: 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.

Abstract: A water feeding device includes a metal shell and a water conduit. The metal shell includes a through hole. The water conduit is made of food grade material or non-metallic material, and is disposed in the through hole, wherein when water passes through the water conduit, the water doesn't contact of the metal shell.

Abstract: A separated-control valve device includes a sleeve having two inlet holes and an outlet hole defined therein. A limiter is received in the sleeve and has two grooves defined therein. A control assembly received in the limiter. The control assembly has a valve seat, two valves mounted in the valve seat, two driven members relatively connected to the two valves, two operating levers relatively connected to the two driven members.

Abstract: A separated-control valve device includes a valve seat having two inlets and two outlets respectively defined therein. A valve plate is irrotatably mounted on the valve seat and has two inlets and two outlets respectively corresponding to the two inlets and two outlets of the valve seat. A control module is mounted on the valve plate and including two valves slidably mounted on the valve plate. Each of the two valves has a guiding recess defined therein for selectively communicating with the inlet and outlet. A control seat is irrotatably mounted on the valve plate. Two levers are pivotally mounted in the control seat to respectively connect to the two valves for slidably moving the two valves.

Abstract: A separated-control valve device includes a valve seat having a space defined therein. An inner lower periphery of the space has two inlets and two outlets are defined therein and communicated with the space. A control assembly is partially and pivotably received in the space in the valve seat. The control assembly has a first valve and a second valve for respectively adjusting water flowing from the inlet to the outlet. A limiter is mounted on the valve seat for confining the control assembly received in the space.

Abstract: A faucet assembly includes two faucets and two connection pipes are connected to the two faucets. A conjunction portion is connected between the two connection pipes and an outlet pipe extends from the conjunction portion and has outlet. A control valve unit includes two control valves which are respectively received in two respective recesses in the conjunction portion. The two recesses communicate with the outlet pipe. Each control valve includes a sealing member which movably seals the connection pipe corresponding thereto. The water pressure from the other connection pipe cannot move the sealing member so that the water with larger pressure cannot enter the connection pipe in which the water pressure is lower.

Abstract: A faucet assembly includes a body having a handle pivotably connected thereon, a hot water connection end and a cold water connection end are located at two ends of the body. An outlet pipe is located between the hot water connection end and the cold water connection end. A coating is coated on the body and composed of temperature-sensible or light-sensible material. The coating changes its color according to temperature of the water passing through the outlet pipe or type of light so that the users are acknowledged the status of the water coming from the faucet assembly.

Abstract: A water outlet coupling head includes a hollow coupling head body, a rotary bolt running through the interior of the coupling head body, a coupling member and an elastic thrust member. The coupling head body is coupled with a spout of a water outlet head. The rotary bolt has a first end perimeter which has a detent member extending radially outwards and a second end perimeter which has a diameter smaller than the first end perimeter to run through the thrust member and fasten to the coupling member. The thrust member has one end pressing a bucking ring located in the coupling head body and another end ramming a pressing portion of the rotary bolt. Thereby the coupling member can be fastened to the water outlet head and positioned in a selected direction.

Abstract: A “virtual string” is generated for synthesizing sound produced by plucked-string instruments using recurrent neural networks. The disclosed recurrent neural network, called a Scattering Recurrent Network (SRN), is based on the physics of waves traveling in the string. Vibration measured from a plucked string is used as the training data for the SRN. The trained SRN is a virtual model capable of generating tones similar to the tones generated by the physical string. As with a real string, the “virtual string” corresponding to the SRN responds differently to different types of string “plucking” motions.
