Abstract: A hill-hold control system for a vehicle. The hill-hold control system includes a first wheel brake (120A, 120B), a second wheel brake (120C, 120D), a braking indicator (brake pedal), a drive away indicator (accelerator), and a controller (130). The controller is configured to determine that the vehicle is at standstill, detect from the braking indicator that braking is no longer desired, adjust a braking pressure at the first wheel brake, adjust a braking pressure at the second wheel brake, detect from the drive away indicator an operator's desire to drive away, and when the operator's desire to drive away is detected, removing the braking pressure at the first wheel brake and the braking pressure at the second wheel brake.

Abstract: A mechanism for reducing brake noise during braking of a vehicle. The mechanism includes controllers and methods that “hold” a currently applied braking torque rather than applying the operator-requested braking torque when a vehicle is traveling at a low speed and the operator-requested braking torque is within a predetermined range. The controllers and methods “release” the previously “held” braking torque and apply the operator-requested braking torque once the operator-requested braking torque is outside the predetermined range.

Abstract: The XAM architecture that specifies a software program instrumentation and data collection method and system is disclosed. The XAM architecture includes definition of a measurement type hierarchy, the definition of an XAM API that adapts an application program to a local XAM library, and a message protocol, based on XML, through which the XAM library is configured by, and sends collected data to, an XAM services process. Predefined measurement types include primitive measurement types and aggregate measurement types, the latter allowing for significant decrease in data transmission overheads between the XAM library and the XAM services process because of data filtering and processing by XAM library routines.

Abstract: In a mobile radio network such a GSM network, an operative identity code is passed by a mobile station to the fixed network part at the start of each communication transaction. This operative identity code will either be the unique identity code (IMSI) assigned to the mobile-station user or, more usually, a temporary, substitute, identity code (TMSI) allocated by the fixed network part with a view to obscuring the identity of the user to anyone monitoring the network radio traffic. Whilst the fixed network infrastructure knows the association between a temporary identity code (TMSI) and the corresponding unique identity code (IMSI) of a user, this information is generally not readily accessible.

Abstract: A method is provided of following a communication transaction during which a communicating mobile station (12) is handed-over from one radio cell to another in a mobile radio system. The transaction is followed across the handover by monitoring signaling messages on the signaling paths in the mobile radio system to detect the occurrence of common parameters related to communication transactions subject to handover. By correlating these parameters it is possible to associate fragments of the same transaction that give rise to signaling messages on different signaling paths. Thus in the case of a GSM mobile radio system with monitoring of the A interfaces, the parts of a communication transaction split by a handover from one BSC (17A) to another (17Z), can be associated by correlating the RR3 Handover Command signaling units appearing on the signaling links (68,69) to the old and new BSCs (17A,17Z).
