A glazing unit is provided for producing an aesthetically pleasing effect. The glazing unit may include at least one polymer with a first structured surface to which a photonic structure is applied. The surface can reflect a first partial spectrum of incident electromagnetic radiation, and can transmit a second partial spectrum of incident electromagnetic radiation. A reflected proportion corresponds to a higher harmonic and is in a visible spectral range.

Glazing unit, method for the production thereof and use thereof

An identification device is provided having an optical detector (), a controller () and an identification transmitter unit (), wherein the optical detector () has a detection area with an identification pattern partially covering the detection area and the controller () is designed to interact with the detector () and the identification transmitter unit () in such a manner that the identification transmitter unit () can be activated to transmit an identification signal depending on an analysis of the temporal sequence of measurement signals from the detector (). A method is also provided for identifying an object by an identification system.

Identification device, identification system and method for identifying an object

A glazing unit is provided for producing an aesthetically pleasing effect, comprising or consisting of at least one pane, said pane having a first structured surface to which a three-dimensional photonic structure is applied and the average refractive index of the photonic structure being higher than approximately 1.6 or higher than approximately 1.8 or higher than approximately 1.95. A method of producing such a glazing unit and the use thereof is also provided.

A device for subjecting a flying insect to lethal radiation. The device has a measurement beam source for producing a measurement beam, a deflection unit for deflecting the measurement beam, a lethal radiation source for producing a lethal beam and a measurement beam detector. The measurement detector has a photodetector element, the deflection unit and the measurement beam detector are arranged and cooperate such that the measurement beam sweeps the detector surface of the measurement beam detector. The device includes an evaluation unit connected to the measurement detector and the lethal light source to determine an attenuation time period of an attenuation of the measurement beam between the deflection unit and the detector surface and to control the lethal light source depending on said attenuation time to emit a lethal beam impulse. A method for subjecting a flying insect to lethal radiation is also provided.
