  • Patent number: 8326495
    Abstract: In a regulating system and method of regulating the chassis of a motor vehicle, sensor data which are present for regulating the suspension and the damping of a vehicle body vehicle and describe the suspension state are forwarded to the regulating module of an antilock brake system. A state of the motor vehicle with regard to a brow situation can be determined from the sensor data. The sensor data or the state with regard to the brow situation are/is taken into consideration in the regulating module of the antilock brake system when determining control signals for regulating the brake pressure in brake apparatuses which are assigned to the wheels, in particular in the brake cylinders. This increases the driving safety considerably when driving over a brow and immediately after driving over a brow and increases the efficiency and reliability of the antilock brake system substantially in corresponding driving situations.

  • Patent number: 8327412
    Abstract: A method for interference-free, centrally controlled switchover from a first to a second program channel in a data transmission system for distributing encoded program data streams to multiple subscribers includes delivering at least two program data streams, each of which is associated with a separate program channel, to a separate, controllable encoder. The program data streams are encoded in the associated encoders. The encoded first and second program data streams are fed into a distribution network. One encoded program data stream is delivered through a routing device to at least one target subscriber. Control parameters are provisioned in a central control device which permits a synchronized activation of the controllable encoders and at least one switching device for interference-free switchover of the program channels. An interference-free switchover from the first to the second program channel is executed.

  • Patent number: 8325682
    Abstract: A resource release control method, a communication system, and a device are configured to delete a bearer context on an original-side heterogeneous-system management network element (NE) even if a target-side management NE does not support interaction with a serving gateway (S-GW) and does not support an idle mode signaling reduction (ISR) mechanism. The resource release control method includes: acquiring version information of a target-side management NE, when a user equipment (UE) activating an ISR mechanism is handed over from an original-side network to a target-side network; and deleting a bearer of an original-side heterogeneous-system management NE, if the version information indicates that the target-side management NE does not interact with an S-GW and does not support the ISR mechanism. Meanwhile, a communication system and a relevant device are also provided.

  • Patent number: 8321738
    Abstract: A method, system, and device for retransmitting data are provided. The method includes the following steps. In Step A, a receiving device detects a received frame that bears data, determines that the data frame is damaged, and judges whether the number of the damaged frames meets a set retransmission threshold value in a set range or not. If yes, Step B is performed. Otherwise, Step C is performed. In Step B, the receiving device sends a retransmission request to a sending device, the sending device retransmits the frame, and the process turns to Step A. In Step C, the receiving device performs a decoding processing on the data borne in the damaged frame that is received.
