  • Patent number: 6307866
    Abstract: A broadband telecommunications system comprises at least one broadband telecommunications switch, and a data transmitter coupled to the broadband telecommunications switch and to each of a plurality of data sources. The system operates to communicate date from the data sources to destinations in the form of a plurality of cells, the communication being arranged to satisfy predetermined transmission parameters. The transmission parameters include an initial cell rate representative of a maximum rate at which data from the data sources may be initially communicated to the telecommunications switch, when the sources become active.

  • Patent number: 6296319
    Abstract: A fastening arrangement for a motor vehicle wheel made of a light metal alloy which is formed by an interior wheel shell and an exterior wheel shell which are fastened to a wheel disk chamber by way of wheel bolts which are arranged concentrically with respect to a wheel hub. The two shells of the wheel can be connected in a mutually sealed manner by way of wheel bolts inserted in bushes, and the bushes are pressed into bores of the shells and held in an embedded manner in a sealing mass. A spacer member is interposed between the wheel chamber and the interior wheel shell. The spacer member is made of a material different than the material of the interior wheel shell and the material of the brake chamber, to facilitate corrosion resistance.

  • Patent number: 6296326
    Abstract: An automatic braking operation is triggered before the operation of the brake pedal if, as the required criterion, the operating speed exceeds a triggering threshold value when the gas pedal is released. The triggering threshold value is adapted to the driver's actions to achieve a more reliable separation between necessary and unnecessary triggerings of the automatic braking operation. At least one magnitude is detected which represents the driver's actions and, on the basis of this magnitude, the triggering threshold value for the automatic braking operation is determined. It is thus unimportant whether the required criterion for the triggering of the automatic braking operation is sufficient or whether additional criteria are required for this purpose, such as the determination of a transfer of the driver's foot from the gas pedal to the brake pedal.

  • Patent number: 6283093
    Abstract: A method for determining the ignition angle for an internal combustion engine with adaptive knocking control, in which the occurrence of knocking is reduced by a controlled adjustment of the ignition angle in the retarded direction. The current values for the adjustment in the retarded direction are stored in a characteristic diagram in an operating parameter-dependent fashion. An average adjustment in the retarded direction is determined from these characteristic diagram values, and both a correction ignition angle and a control range limitation for the knocking control are determined therefrom. The fuel quality and ambient influences are automatically sensed with reference to a learned RON level and are also used to reduce the amount of energy expended to control engine knocking.

  • Patent number: 6276153
    Abstract: A method and a device for heating and cooling a compartment of a motor vehicle powered by an internal combustion engine are described. During a cooling operation, a medium in the circuit is guided through a compressor, an ambient heat exchanger, a throttle device, and an interior heat exchanger which are connected in series and form an integral closed circuit. On the high-pressure side of the circuit, a supercritical pressure is produced at the same time that a subcritical pressure is produced on the low-pressure side of the circuit. During a heating operation, the high-pressure side of the circuit during the cooling operation becomes the low-pressure side and the low-pressure side of the circuit during the cooling operation becomes the high-pressure side. The medium in the circuit is conducted in the interior heat exchanger at a supercritical pressure, with heat energy being transferred from the medium in the circuit to the compartment air supplied to the compartment.

  • Patent number: 6266847
    Abstract: A door closer assembly and a method for operating a door closer assembly. The door closer assembly includes a housing and a door piston guided in the housing. The door piston is operably connected to move a door. A spring piston is guided in the housing and is operable to assist movement of the door piston toward a door closing position. The spring piston is situated in the housing and is acted upon by a spring. The door closer assembly also includes a hydraulic control circuit containing hydraulic fluid which is operable to selectively eliminate a coupling of the door piston and the spring piston from one another during a portion of the travel path of the door piston in the housing. The door closer of the present invention improves the comfort of passing through a door by providing different transmission ratios and therefore, different moment curves.

  • Patent number: 6267707
    Abstract: A process for shifting an automatic transmission in a motor vehicle having an electronic engine timing system which is electrically coupled with a driving element (e.g., an accelerator pedal). The electronic engine timing system is electrically coupled with an electronic transmission control system. When a change-gear operation is taking place in the automatic transmission and the automatic transmission is in a critical shifting phase, and simultaneously the driving element is adjusted to demand increased output from the engine, if the rate of the adjusting change and the extent of the desired new output together exceed a predetermined value, the increase in engine output is delayed and/or the gradient of the engine output increase is limited or delayed by adjusting the engine timing system.
