Abstract: A sensor device, comprising a pyroelectric sensor which is set to operate in daylight, especially an infrared-based motion sensor, and an electronic evaluator. The electronic evaluator is connected downstream of the sensor and is configured to produce a control signal in response to a detector signal from the sensor in relation to a threshold value. The electronic evaluator also has a sensing device for measuring a daylight ambient brightness and a compensating device which is configured to respond to a considerable change in the daylight ambient brightness by modifying the threshold value and/or the detector signal to compensate.

Abstract: The invention pertains to a pressure and temperature sensor, in particular for determining a pressure and temperature condition in a cavity of an injection molding apparatus or the like having a pressure body which co-operates with a sensor housing and which in a mounted condition can be acted upon by a pressure in the cavity and which is intended for transmitting the pressure to a piezoelectrically acting sensor arrangement, wherein an electrical signal generated by the sensor arrangement as a reaction to the pressure is taken out of the sensor housing by means of an electrical contact device, wherein a thermoelectric detector element is fitted in the pressure body and an electrical temperature signal generated by the detector element is taken out by way of the electrical contact device.

Abstract: An automatic switching device for flourescent light has a light sensing element that reacts to ambient light and a switching unit designed to react to an output signal from the light sensing element and to activate or deactivate the flourescent light. The switching unit has a reference threshold generator. The flourescent light is activated or deactivated depending on whether the output signal from the light sensing element exceeds or falls below a threshold generated by the reference threshold generator and the threshold level depends on the luminosity sensed by the light sensing element. The switching unit further includes a delay designed for preventing signal processing by the switching unit for a present period of time upon switching on of the flourescent light.

Abstract: An electric device for evaporating substances, such as perfumes or the like, including a housing which is adapted to have inserted therein a receptacle containing the substance in question. The device has an electric circuit supported in the housing and formed of two circuit components which are placed one on top of the other and between which a PTC element is arranged. Each of the circuit components is formed of an injection molded part and a stamped sheet metal component embedded therein. The circuit components are coupled to one another mechanically and electrically by an integrally formed stamped sheet metal component and one circuit component is folded onto the other when the device is being assembled.

Abstract: An electric device for evaporating substances, comprising a housing, a printed circuit board supported in said housing and used for an electric heating element, and a toggle switch including an operating element which is adapted to be pivoted by a defined angle. The toggle switch is provided with an integral strip-shaped sheet-metal spring serving simultaneously as a switching element for interrupting and for establishing an electrically conductive connection between two contacts and as a resilient element holding the switching element at two stable switching positions. The strip-shaped sheet-metal spring has two end pieces, one end piece being coupled to the operating element and the other end piece abutting directly on one of the two contacts. Furthermore, the strip-shaped sheet-metal spring includes a 3/4-circular bend which is brought into contact with the other contact by pivoting the operating element.

Abstract: An electric device for vaporization of additives having a housing with an electric heating disposed therein. The heating includes a heating element and a heat exchanger, to supply the heat generated by the heating element to the heat exchanger and to convey it to the substance to be vaporized. The heating element is a PTC element, clamped between two electrodes and at least one of the two electrodes is disposed in proximity to the heat exchanger and is integrally formed with it.

Abstract: An electric device for the vaporization of additives has a housing in which an electric heating unit is disposed and into which the additive is to be inserted. The device has a heat exchanger, which is in heat connection with the heating unit and which is disposed at a location to vaporize the additive. The device includes a plug for a wall socket which is rotatable relative to the housing and has a rotating joint carrying a set of contacts. A set of counter-contacts is at the housing and arranged in a manner to produce an electric connection in two positions of the plug offset from the housing by about 90.degree., and an annular range in between having a switching position in which the connection is opened.
