Abstract: A method and a computer program product controls the water supply in a sanitary installation having a cold water supply line and a hot water supply line, a valve battery, which is connected to a power supply, and a sensor unit connected to the power supply. At least one trigger means outputs an action signal to an electronic controller when activated by a user by tapping on the trigger means that is embodied as a switch or by at least partially penetrating into the detection area of a trigger means that is embodied as a proximity sensor.

Abstract: The invention relates to a device (2) for controlling and/or regulating the supply of a medium using a supply unit for an impingement device. Said supply unit comprises at least one shut-off member and each shut-off member can be moved into a closed position and at least one open position by means of an actuating element. The device comprises a sensor unit (50) for determining in a contactless manner the presence of a material that is to be impinged by the medium. The inventive device (2) is characterized in that said sensor unit (50) is additionally configured for the contactless determination of the relative position of the material in relation to the impingement device (10) and for the output of signals, which act on the actuating elements in such a way that the later moves the shut-oft members into a position that corresponds with the presence and the location of the material to be impinged by the medium.

Abstract: A method and computer program product controls the water supply in a sanitary installation having a cold water supply line and a hot water supply line, a valve battery, which is connected to a power supply, and a sensor unit, connected to the power supply. At least one proximity sensor outputs an action signal to an electronic controller when a person at least partially penetrates into the detection area. A timeslot is assigned to every action signal and, after at least one further action signal, which is triggered within the timeslot through repeated penetration of a person into the detection area, the controller outputs a command which causes the valve battery to change the temperature and/or the flow value of the water supply to the sanitary installation in relation to the number of action signals triggered, and after expiration of the last timeslot, to release the water supply into the sanitary installation.

Abstract: A method for generating an electrical signal and a sensor device (10) for executing the method. The signal is generated because of a change in a fluid-filled space. A sensor element (12) of the sensor device (10) detects the heat transfer over time between the sensor element (12) and the fluid. The sensor element (12), which has a temperature-dependent electrical conductivity and to which a voltage has been applied, is brought to a temperature which lies outside the range of the fluid temperatures. In the passive phase, the fluid is brought to a constant passive temperature by a heat transfer between the sensor element (12) and the surroundings. The sensor device (10) provides a constant passive output voltage. A heat transfer between the sensor element (12) and its surroundings takes place in the active phase by changes in the fluid-filled space. The sensor device (10) provides an active output voltage, which is different from the passive output voltage.
