System and method for generating white-box implementations of software applications
A development suite for generating files, such as DRM-protected files, using white-box cryptography. The suite consists of a code generation tool, a data transformation engine, and a white-box data generation tool, and a white-box library. In the white-box cryptography context, the data transformation engine is used to protect the boundary between the cryptographic operation and the surrounding code. In particular, the data transformation engine is used to apply data transformations to the inputs to and outputs from the cryptographic operations. If the user specifies that transformations are required via a white-box parameterization file, the code generation tool puts the information specified by the user into a form the data transformation engine understands, namely as qualifiers on data variables and function prototypes. The data transformation engine then applies the specified transformations, and passes information to the data generation tool regarding which transformations were chosen. |

Control apparatus for hybrid vehicle
An object of the present invention is to detect the generation of a drag torque in a locking mechanism, in a hybrid vehicle in which a speed change mode can be changed between a fixed speed change mode and a stepless speed change mode by the action of the locking mechanism. In a hybrid vehicle, a brake mechanism is a wet multiplate brake apparatus and can selectively lock a motor generator. On the other hand, in a case where the drag torque is generated in the brake mechanism, if the motor generator is in a positive rotation state, an actual motor generator torque (first torque) is greater than a torque (less as a reaction torque, second torque) calculated from the operating condition of the hybrid vehicle by the amount of the drag torque. If the motor generator is in a negative rotation state, the first torque is less (greater as the reaction torque) than the second torque. The ECU uses this phenomenon to detect the drag torque. |

System and method for calculating flight predictions by vertical sections
The invention relates to a system and a method for calculating flight predictions of an aircraft in which an intermediate prediction horizon is defined between the flight phase and the leg. This horizon, that is called vertical section, is defined such that the limit conditions that are applicable to it, for example the target speed, target altitude, characteristic altitude and maximum end-of-section distance, are valid for the entire vertical section. Thus, it is not necessary, in calculations to check the compatibility of the flight parameters with the applicable constraints, to arbitrarily select the constraint that must be given priority. Furthermore, this intermediate level architecture allows for a greater modularity of the prediction management software and therefore a greater factorization of the developments and greater ease of maintenance. |

Method and apparatus for supporting a network initiated handover in a wireless network
Various embodiments are described to address some of the inefficiencies in present-day network initiated handovers. A serving node (121) sends a first message requesting a remote unit (101) to handover but does not indicate any network nodes to which to handover and then receives, in response, a second message indicating a target node (e.g., 122) preferred for handover by the remote unit. The serving node then notifies the target node of a potential handover by the remote unit and sends a third message to indicate to the remote unit to proceed with a handover to the target node. By first obtaining a preferred handover target from the remote unit and then notifying that target node, a network initiated handover may be accomplished more efficiently than by using the known technique of notifying prospective nodes prior to obtaining any acceptance or preference from the remote unit. |

For cellular networks, UMM acts as a traditional HLR; for an Internet telephony network, it acts as the entities that are responsible for user/terminal registration (registrar in SIP, gatekeeper in H.323) and address resolution (proxy server in SIP, gatekeeper in H.323). An optimal gateway selection is possible based on location related information provided by the UMM which had not previously been available. Utilizing the newly available information enables a gateway to be selected which may, for example, enable the circuit switched portion of a call to now be minimized. |
