Abstract: The invention relates to a method for loading, storing and presenting web pages, by which means the required band widths and the time taken to load web pages for an application are reduced. To this end, components or information elements separate from web pages are provided with indicators by which means the expiry dates can be deduced. The indicators are evaluated by the application which may be a browser. In this way, the application can reload only the updated data/components from the original source. Information elements which are constant over a long period of time can be completed or loaded by the application from a memory associated with the same. The loading times and data quantities for a data transmission from an original source to an application can thus be considerably reduced. The invention also relates to an information system which uses said method, preferably in a motor vehicle.

Abstract: Method for buffering audio data in optical recording media, and apparatus using such method for reading from and/or writing to optical recording media in case of an error condition (e.g. upon shock or vibration). It comprises the steps of, as audio data is read from a position on the medium prior to a position corresponding to a verified write position in the memory and in case writing to the memory is inhibited; counting the number of samples read; searching for two subsequent markers distant of one frame (to take into account the case where a marker could be corrupted); determining the remaining distance to the verified write position based on the sample count; restarting writing the audio data to the memory when the data read from the medium corresponds to the verified write position.

Abstract: The present invention relates to a method for controlling a track jump on an optical recording medium, and to an apparatus for reading from and/or writing to optical recording media using such method. According to the invention a method for track jump control includes the steps of defining a first tolerance window adjacent to a target position on the optical recording medium, defining a second tolerance window adjacent to the first tolerance window, after finishing a track jump, reading a sector or subcode on the optical recording medium, if the sector or subcode read after finishing the track jump lies within the second tolerance window, determining that the track jump was finished within the second tolerance window, if the track jump was finished within the second tolerance window, letting the system settle for the remainder of the second tolerance window plus the first tolerance window, and resuming the playback or recording operation at the target position.

Abstract: The proper functionality of a first processor is checked with a second processor. The second processor thereby provides the first processor with a start value and a computation rule. The first processor carries out the specified computation rule using the predetermined start value, and returns a result to the second processor. The second processor checks the result against a stored comparison result. The computation rule is defined such that the basic instructions which are used for programming the first processor are checked.

Abstract: The functionality of a first processor is checked with a second processor. A data word with a specified number of data bits is supplied to the first processor from a second processor at specified time intervals. Each data bit is assigned a function. Having processed a function, the first processor inverts the associated data bit and, at the end of a time slice, passes the data word to the second processor, which checks the transferred data word.

Abstract: A control device of the internal combustion engine has a first arithmetic unit and a second arithmetic unit. The arithmetic units process a control program with a first, second and third program level. In the second program level an actuation signal is monitored, and a first emergency operating function is activated in the first program level if the second program level has detected an implausibility of the actuation signal. The third program level is caused to carry out a second emergency operating function if, while the first emergency operating function is being carried out in the first program level, the implausibility of the actuation signal continues to be detected.

Abstract: A reproducing and/or recording device for reproducing, or for recording on, an optical recording medium, having a tracking sychronization circuit (1), which has a variable center frequency generator (12, 13). The tracking synchronization circuit (1) can be operated with different center frequencies depending on application, and this has the advantage that identically designed tracking synchronization circuits (1) can be used for different purposes. It is advantageous that adaptive adjustment of a center frequency once prescribed is additionally possible during operation, thus increasing the capture range of the tracking synchronization circuit.

Abstract: A bumper arrangement for vehicles is disclosed, particularly for passenger vehicles and the like. The bumper arrangement includes a dimensionally stable support and an elastic covering forming the end area of the vehicle body. The covering extends at a distance from the support and is fastened locally at the body, a recess being provided at the covering for receiving a license plate. So that the tool costs for the covering are reduced while taking into account specific requirements of different countries and to also ensure that the covering exhibits a good performance, can be mounted easily and is also repair-friendly, the elastic covering comprises several parts that are joined together in transverse direction of the vehicle.

Abstract: An automotive vehicle, especially a passenger car, comprises a bumper, at least two radiators and an air duct system for guiding the cooling air stream over the radiators. To provide a cooling air guidance system which is simple in construction, which functions satisfactorily, and which can be integrated into the vehicle with few problems, each radiator is provided with a separate air duct. The inlet ports and/or the air guide means are arranged in an elastic cover of the bumper which forms the end portion of the vehicle. At least one inlet port and one air duct extend, in part through a rigid support of the bumper. The inlet port is located in a zone of maximum dynamic pressure, namely underneath a nose-like projection of the cover.

Abstract: A bumper formed by a rigid support of U-shaped cross section and a resilient guard covering it, with the guard having approximately horizontally aligned guide bars which rest against parallel legs of the rigid support and interact in a reinforcing manner with holding fixtures of the rigid support. For purposes of safe assembly and avoidance of overstressing the guard, additional horizontally-running cross bars are located at a vertical distance from the guide bars and include portions that protrude beyond the support. The protruding portions of the cross bars are connected to each other by means of a fastening link.

Abstract: A bumper for vehicles, in particular automobiles, having a beam and dampers secured to the beam by means of retention devices in a manner so as to eliminate the use of auxiliary attachment devices, such as washers, cotter pins, etc., in order to prevent dislodgment of a bolt securing each retention device to the beam. In accordance with the preferred embodiments, each retention device and damper is provided with a bore. Within this bore a bolt is inserted that extends from an upper portion of the retention device, through the damper into a lower portion of the retention device. The bolt is retained in this bore either exclusively by bumper flanges overlying the opposite ends of the bore, or by the use of only one such flange and a blind bore having a check wall in the lower portion of the retention device.

Abstract: An automobile bumper having a support that is rigid in its configuration and a covering of elastic material is fixed to the car body via a flangelike portion by fastening means but can be bolted. Visible depressions, indentations or the like in the covering are avoided in a preferred embodiment by a strip having a widened portion that penetrates into the flangelike covering and which has sleeves which extend through the covering so as to bear upon the vehicle body in the region of the fastening members.

Abstract: An improved motor vehicle bumper comprises a form-stiff support, a headlight and an elastic covering forming the end portion of the vehicle body. The headlight is provided in a recessed portion and is held by a pair of holding members at wall portions of the elastic covering. Impact on the covering causes the headlight to be pivoted about its attachment to one of the wall members and prevent damage to the headlight proper.
