Abstract: A navigation system for a vehicle including a mobile navigation computer, a vehicle-based central control unit, a GPS receiver, a communication link between the mobile navigation computer and the central control unit, wherein position data for the vehicle is processed in a navigation unit in the mobile navigation computer to form information relevant to the navigation. The navigation information is transmitted from the navigation computer to the control unit for a respective maneuver which is to be performed, and this information is output in at least one of visual and audible forms via the central control unit. The position data for the vehicle is determined by the position-finding unit of the central control unit, and is transmitted to the mobile navigation computer, wherein the vehicle is navigated on the basis of data calculated in the navigation unit of the mobile navigation computer.

Abstract: The invention relates to a wireless tracking and monitoring system having at least one mobile unit and at least one central unit, wherein each mobile unit has at least one first communication component for communication with the central unit, wherein each mobile unit has at least one sensor, and wherein position finding can be carried out via a position finding system by at least one of the sensors. In this case, each mobile unit has a second communication component for communication with the central unit or with a target unit, and wherein the first and the second communication components of the mobile unit can be operated at the same time.

Abstract: The invention relates to a control device, a hybrid device, a method for operating an arrangement (A) for processing data packets, an arrangement (A) for processing data packets and to an electronic device.

Abstract: For the transmission of at least one information data record between a mobile trigger apparatus (9) and at least one fixed station (7a-d), the transmission is effected via an ad hoc network, with a distance between the mobile trigger apparatus (9) and the fixed station (7a-d) being able to be greater than the latter's transmission and reception range by virtue of the transmission then being effected using at least one mobile transmission apparatus (13a/b; 15a-c; 19a/b). The information data record is transmitted to the nearest fixed station (7a-d) directly or via the at least one mobile transmission apparatus (13a/b; 15a-c; 19a/b) or via further mobile transmission apparatuses. The invention is intended to permit data transmission at low transmission and reception power as quickly as possible from a mobile apparatus to a remote fixed station.
