Abstract: The present disclosure concerns a safety strip for a door, in particular for a door of a means of transport. The safety strip is elastic and/or flexible, has at least one receiving space, and comprises a sensor arrangement. The sensor arrangement is set up to emit electromagnetic radiation into a monitored area and to receive such radiation from the monitored area. The sensor arrangement is arranged in the receiving space in such a way that the safety strip completely encloses the sensor arrangement at least in one plane.

Abstract: An FMCW radar device for determines the distance of an object from an element of the radar device. An FMCW radar device is disclosed having a predetermined time interval for the change in radar frequency of 100 ?s or less, a controllable oscillator configured such that while the radar device is operating the radar frequency can be tuned within the predetermined time interval via a tuning bandwidth of at least 4 GHz, and a phase comparator configured such that same provides a phase stabilisation of the generated radar signal for at least 900 frequencies of the radar signal within the tuning bandwidth of the controllable oscillator and within the predetermined time interval.

Abstract: A method of spectrometry on a spatially extensive sample with generation of a measure in respect of a match of a detected spectrum of a first generation with a single or a plurality of predetermined comparative spectra of chemical substances is disclosed. The method includes the steps: determining at least one location of the first generation on the sample, irradiating the sample with electromagnetic radiation with a plurality of frequencies or a frequency band between 1 GHz and 30 THz at the given location of the first generation of a first order on the sample, frequency-resolved detection of a measure in respect of the intensity of the electromagnetic radiation irradiated on to the sample at the location of the first generation and transmitted or reflected by the sample as the spectrum of the first generation, and calculating a respective measure in respect of a match of the detected spectrum of the first generation with one of the comparative spectra.
