Abstract: Proposed is a ring-shaped computer device for wearing on the human body, in particular on a finger, which computer device is configured to continuously collect vital parameters and/or bioactive markers of a wearer and make them available to a connected device and has a ring-shaped main body with an at least partially optically transparent inner surface which faces the wearer's skin, a first sensor for optically detecting vital parameters, in particular a heart rate, via the wearer's skin, wherein the first sensor is separated from the wearer's skin by at least one optically transparent detection area of the inner surface, and a second sensor for determining electrical properties of the wearer's skin by means of electrical contacts, wherein the electrical contacts are applied to the optically transparent inner surface of the main body.

Abstract: A ring-shaped computer device for wearing on the human body, in particular on a finger, which computer device is configured to continuously collect vital parameters and biomarkers of a wearer and make them available to a connected device and includes a plurality of sensors for recording the vital parameters and biomarkers, a printed circuit board for receiving the sensors and a data interface, a processor, and at least two battery modules for supplying power to the printed circuit board and the processor, which are connected together to form an overall battery.

Abstract: An audio device for a vehicle includes a loudspeaker system having a plurality of loudspeakers, which are arranged spatially such that they enable a three-dimensional listening experience in a vehicle interior. The audio device also includes a control unit which is coupled to the loudspeaker system and which is configured to control at least one loudspeaker of the loudspeaker system in order to reproduce a position-specific warning signal which is linked to a specific position. For reproducing the position-specific warning signal, the control unit controls only the loudspeaker or those loudspeakers of the loudspeaker system which is/are closest to the specific position.
