Abstract: A device for providing a skin or wound dressing, a wound treatment set, and a method to provide a skin or wound dressing, wherein the skin or wound dressing includes an active substance, and wherein the device comprises at least two chambers for the storage of at least two liquids, which are openable by mechanical action, so that, after opening of the chambers, the liquids are miscible and are transferrable to an active substance carrier.

Abstract: A transmitting apparatus for transmitting a frequency-modulated signal is provided. The transmitting apparatus includes a pilot tone generation device for generating a pilot tone. The transmitting apparatus also includes a modulation device for obtaining the generated pilot tone and a modulating useful signal and for generating a frequency-modulated signal based on a combination of the generated pilot tone and the modulating useful signal. The generated pilot tone has a frequency outside a frequency range of the modulating useful signal in order to vary a frequency range of the frequency-modulated signal.

Abstract: A receiving apparatus for receiving a useful signal is provided. The receiving apparatus includes a plurality N of antennas for receiving a respective carrier signal containing the useful signal, and a determination device for determining channel properties of N transmission channels before receiving the carrier signals. The receiving apparatus also includes a transmission channel for transmitting the respective carrier signal being assigned to each antenna, and a switching matrix for selecting M transmission channels from the N transmission channels based on the determined channel properties, where 1?M<N. The switching matrix has a combination algorithm for combining the carrier signals of the M selected transmission channels. The receiving apparatus also includes a demodulation device for determining the useful signal from the received M carrier signals of the M selected and combined transmission channels.

Abstract: A method for determining a respiratory rate of a living being includes emitting a radio signal using a radio transmitter arranged on the living being. The emitted radio signal is acquired, and the respiratory rate is determined based on the acquired radio signal.
