摘要： A smoke detector, on a base element with a flat installation surface, features a first light transmitter attached to the installation surface for emission of a first illumination light, a first light receiver attached next to the first light transmitter for receiving a first measurement light which results from a backscattering of the first illumination light at a measurement object located in a first detection area. The smoke detector further features a second light transmitter attached to the installation surface for emission of a second object illumination light, a second light receiver attached next to the second light transmitter for receiving a second measurement light which results from a backscattering of the second illumination light at a measurement object located in a second detection area, and a data processing device, which is used for joint evaluation of a first output signal of the first light receiver and of a second output signal of a second light receiver. In addition a method for the detection of smoke using the described smoke detector is specified.

摘要： A device for detecting smoke based on the principle of optical scattered light measurements has a light emitting device, configured to issue a temporal succession of light pulses. A first light pulse has a first spectral distribution and a second light pulse has a second spectral distribution that is different from the first spectral distribution. A light receiver receives a first scattered light from the first light pulse and a second scattered light from the second light pulse, and generates a first output signal that is indicative for the first scattered light, and a second output signals that is indicative for the second scattered light. An evaluation unit compares the first output signal with the second output signal. In a preferred embodiment of the device, the light emitter and the light receiver are arranged directly next to one another.

摘要： A device and a method enable a spatially resolved measurement of a temperature inside a spatially linear detection region. The device includes a measuring body having a first electric conductor, a second electric conductor, and an insulating material, which extends between the two electric conductors. The insulating material has a temperature-dependent specific electric resistance. The device further includes a measuring unit, which is connected to the first electric conductor and to the second electric conductor. The measuring unit has a transmitting unit and a receiving unit. The transmitting unit is equipped to apply a time-dependent electric input signal to the two electric conductors. The receiving unit is equipped to detect a time-dependent electric response signal of the measuring body to the input signal. Furthermore, an alarm system is described, which in addition to a central unit has at least one temperature measuring device of the type described above.
