Abstract:
A circuit arrangement for compensating for an attenuation occurring in an antenna signal link between a mobile radio terminal and an antenna has at least one antenna signal amplifier in the antenna signal link and a control unit for adjusting a gain factor. The antenna signal conducted through an associated antenna signal amplifier is amplified or attenuated. The circuit arrangement has a detection unit for detecting an antenna signal power (PM, PA) of the antenna signal in the signal path of the antenna signal link. The control unit is configured for changing the gain factor, detecting a change, changing the transmit power (PM) of the mobile radio terminal, and adapting the gain factor to the coupling attenuation of the antenna signal link in dependence on a detected response of the mobile radio terminal.

Abstract:
In order to find a parked vehicle with the aid of a separate navigation device which is independent of the vehicle, a close-range communication connection is established between a vehicle device permanently located in the vehicle and a portable storage device. The communication connection is maintained as long as the storage device is at close range. Collapse of the close-range communication connection between the storage device and the vehicle device is used as the criterion for storing current position data of the vehicle. A navigation device which is in the form of a separate device and contains navigation software and suitable electronic navigation maps, reads out the current position data and is used for navigation to the parked vehicle.
Abstract:
A retaining arrangement for a mobile communication device has an accommodating means which accommodates a mobile communication device. The retaining arrangement includes a retaining setting in which the mobile communication device is retained in the accommodating means, and a release setting which allows the mobile communication device to be inserted into the accommodating means. The retaining arrangement is characterized by a locking means which can be moved into a locking setting and into an unlocking setting, wherein the accommodating means can be moved out of the release setting into the retaining setting only when the locking means is in the unlocking setting.

Abstract:
A circuit arrangement (1) for compensating for a damping occurring in an antenna line between a mobile radio terminal (2) and an antenna (3), comprising a plurality of partial branches (T1, T2, T3) in each case for assigned transmission services for specific frequency bands, is described. A first partial branch selection switch (S1), on the terminal side at an antenna connection (4) of the circuit arrangement (1), said antenna connection being connectable to the mobile radio terminal (2), is connected to a selected partial branch (T1, T2, T3) depending on the switching position and a second partial branch selection switch (S2), on the antenna side at an antenna connection (5) of the circuit arrangement (1), said antenna connection being connectable to the antenna, is connected to a selected partial branch (T1, T2, T3) depending on the switching position such that a partial branch (T1, T2, T3) selected by the switching position of the partial branch selection switches (S1, S2) is switchable into the signal path between mobile radio terminal (2) and antenna (3). The partial branches (T1, T2, T3) have at least one reception amplifier (EV21, EV22, EV31, EV32, EV33) and/or a transmission amplifier (SV21, SV22, SV31, SV32, SV33). The circuit arrangement (1) has a pulse detection unit (6) for detecting pulse properties of a high-frequency mobile radio signal of a mobile radio terminal (2) that can be connected to the circuit arrangement, and is designed for selecting a partial branch (T1, T2, T3) by driving the first and second partial branch selection switches (S1, S2) depending on the detected pulse properties.
