Abstract: In a method for searching for signals among interference signals in a multi-channel radio receiver, at least two different data signals are transmitted on at least one physical channel of a radio system to a common receiver. The search for a signal is initiated on any channel, starting with a sequential search of a useful signal by measuring the current signal strength in the form of the RSSI value; a search is made for a signal criterion of the signal and when said criterion has been identified, the measured RSSI value is compared with a predefined RSSI threshold value; if the RSSI threshold value is exceeded, the search for a signal is switched to a search for a data frame and if a data frame is found, the useful data is read; if no signal criterion is identified, if the RSSI threshold value is not exceeded and if no data frame is found, the procedure is interrupted and a new search operation is initiated once a new RSSI threshold value has been defined.

Abstract: A device for controlling a passenger protection system of a motor vehicle includes at least one structure-borne noise sensor, used to receive body vibrations, and an evaluation device, used to evaluate the structure-borne noise signal. The evaluation provides information about an impact object and/or the characteristics of the impact. The evaluation device is configured to analyze the structure-borne noise signal in relation to the frequencies contained therein, wherein the frequency spectrum contained in a signal section is distributed into a plurality of frequency ranges. The current signal energy is determined for each frequency range, and the signal energy of the frequency range is a standardized. The device also comprises a passenger protection system, which can be actuated according to the information relating to the impact object and/or the characteristics of the impact.

Abstract: A device for differentiating between a person sitting on the seat surface of a vehicle seat and an object includes at least one largely flat bearing surface that is arranged over a large part of the seat surface including a central region. The novel device includes a vehicle seat, a cushion with weight sensors that are distributed over the seat surface of the vehicle seat in a plane manner, and an evaluation unit to which the signals of the weight sensors are supplied. A central region of the seat surface is curved in a concave manner in the direction of the bottom of the vehicle, in such a way that a first weight sensor arranged therein is closer to the bottom of the vehicle than a plurality of second weight sensors arranged in the region of the seat surface covered by the object, outside the central region. The capacity to differentiate between a person and an object is especially useful when the object is a child seat. In this case, the triggering of a passenger retaining means must be prevented.

Abstract: The invention relates to a method for configuring a control device and to a corresponding control device. The control device comprises a main memory and a variant memory. A main data record is created in accordance with an identification from a base data record that is specific to said identification and a difference base data record that is likewise specific to said identification. The main data record is then transmitted to a main memory of the control device.

Abstract: A terminal state of a terminal 15 of a vehicle is enabled to be maintained for a minimum period of time even after a drop in the voltage supply. At the same time other loads are to have no effect on the holding time. A control device for controls access to a vehicle and has a voltage source, a voltage supply terminal to which a supply voltage can be applied, and a holding circuit to which the voltage source and the voltage supply terminal are connected in a common circuit point for the purpose of holding an On state for as long as the voltage at the voltage source does not fall below a predetermined value. A switching element that is connected into the circuit between the voltage supply terminal and the common circuit point serves to separate the common circuit point from the supply voltage. The holding time is thus decoupled from the VCC currents drawn by other loads.

Abstract: A device and a method equalize a charge of series-connected individual cells of an energy accumulator with a DC/DC converter. The DC/DC converter draws energy from the energy accumulator or from another power source for charging an intermediate circuit capacitor whose voltage is inverted in a DC/AC converter and the alternating voltage is converted into an intermittent direct current by a rectifier via an AC bus and a coupling element. A switch is placed between the AC bus and each cell thereby enabling the cell to be coupled to the AC bus or disconnected therefrom.

Abstract: A method for transmitting data to a data line between a central control device and a decentralized data processing device. Input data of the decentralized data processing device is supplied to a processing unit of the decentralized data processing device in a first resolution. The processing unit carries out a transformation of the input data according to a calculation rule, and transmits the transformed data to the central control device by way of the data line in a second resolution. The central control device is used to determine, in the framework of a configuration of the decentralized data processing device, according to which calculation rule from a plurality of calculation rule, the decentralized data processing device is to carry out the transformation.

Abstract: A device and a method for differentiating between a person sitting on the seat surface of a vehicle seat and an object such as, for example, a child seat. The device has a cushion provided with weight sensors which are distributed over the seat surface in a plane manner, first weight sensors being arranged in a central region and second weight sensors being arranged on the edge of the seat surface. At least one central weight sensor is differentiated from a plurality of second weight sensors on the edge of the seat surface in that it always emits a comparatively low sensor signal when subjected to the same weight load.

Abstract: A printed circuit board has a first elongated face and a second elongated face opposite the first face. The printed circuit board has at least one first, second and third rigid region in addition to at least one first and second flexible region. The flexible regions are perpendicular to the faces and are thinner than the rigid regions. The first rigid region is only coupled to the second rigid region by way of the first flexible region and the second rigid region is only coupled to the third rigid region by way of the second flexible region. The first flexible region lies flush against the first face and the second flexible region lies flush against the second face of the printed circuit board.
