Abstract: A spectrometry device includes a carrier medium, or waveguide, for transmitting light by internal reflection, and a transceiver device that has at least one light source and a detection device. A transceiver deflection structure couples at least the light emitted by the light source into the carrier medium. A measurement deflection structure, arranged at a distance from the transceiver deflection structure, decouples the light out of the carrier medium onto a measuring surface of the carrier medium so that the biological tissue can reflect the light back to the carrier medium. The reflected light is transmitted back onto the detection device via the measurement deflection structure, the carrier medium and the transceiver deflection structure. The detection device determines an intensity signal of the reflected light which is used by an analysis device to determine a pulse frequency signal and/or a pulse curve signal as a medical characteristic value.

Abstract: The invention relates to a method for carrying out a driving maneuver for creating a gap in the traffic flow, which is multiple lanes wide, involving a first vehicle and a plurality of second vehicles. The first vehicle, which requests the gap in the traffic flow periodically sends corresponding request signals at least to a plurality of second vehicles. The second vehicles that intend to comply with the request send out corresponding signaling signals. As soon as a sufficient minimum number of second vehicles that intend to comply with the request can be determined, the second vehicles participating in the driving maneuver for creating the gap in the traffic flow are informed. The second vehicles participating in the driving maneuver agree on the beginning of the driving maneuver and mutually coordinate their trajectories. One of the second vehicles is designated as the maneuver leader and transmits at least one characteristic of the gap in the traffic flow to the first vehicle.
