20090222653COMPUTER SYSTEM COMPRISING A SECURE BOOT MECHANISM - A secure boot processing may be accomplished on the basis of a non-volatile memory that is an integral part of the CPU and which may not be modified once a pre-boot information may be programmed into the non-volatile memory. During a reset event or a power-on event, execution may be started from the internal non-volatile memory, which may also include public decryption keys for verifying a signature of a portion of a boot routine. The verification of the respective portion of the boot routine may be accomplished by using internal random access memories, thereby avoiding external access during verification of the boot routine. Hence, a high degree of tamper resistance may be obtained, for instance, with respect to BIOS modification by exchanging BIOS chips.09-03-2009
20090276617COMPUTER SYSTEM COMPRISING A SECURE BOOT MECHANISM ON THE BASIS OF SYMMETRIC KEY ENCRYPTION - A CPU, a computer system and a secure boot mechanism are provided in which a symmetric encryption key may be incorporated into a non-volatile memory area of the CPU core, thereby substantially avoiding any tampering of the encryption key by external sources. Moreover, pre-boot information may be internally stored in the CPU and may be retrieved upon a reset or power-on event in order to verify a signed boot information on the basis of the internal symmetric encryption key. Furthermore, the BIOS information may be efficiently updated by generating a signature using the internal encryption key.11-05-2009

20090051215METHOD FOR OPERATING A BRAKE SYSTEM FOR MOTOR VEHICLES - The invention relates to a method for operating a braking system for motor vehicles with electrically actuated hydraulic valves, the coils of which are powered up, at least in phases, with currents which modify the currentless state of the hydraulic valves, in order to heat the hydraulic fluid present in the system. The hydraulic fluid is heated via a heating profile which, in accordance with the hydraulic fluid temperature, activates the heating phase of the hydraulic fluid. The heating profile consists of a first heating phase and, subsequent thereto, a second heating phase. During the first heating phase, the coils are powered up in such a way that the coil temperature at the end of the first heating phase corresponds to a pre-defined temperature value of the coil which is at least approximately maintained during the second heating phase when powering up the coils.02-26-2009
20090055067METHOD AND DEVICE FOR CARRYING OUT A STATIONARY HOLDING FUNCTION ON A MOTOR VEHICLE - A method for controlling a valve for maintaining brake pressure in a specified region of a brake circuit in a motor vehicle, in which the valve is controlled using a first control method, the specified region of the brake circuit is monitored with respect to the occurrence of a loss of brake pressure, and in response to a detected loss of brake pressure, the valve is controlled using a second control method.02-26-2009
20110001351Method and Device for the Reproducible Generation of a Specifiable Final Pressure in a Braking System - To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve.01-06-2011

20090327476Dynamic Infrastructure for Monitoring Service Level Agreements - A dynamic infrastructure for monitoring service level agreements (SLAs) is described. In an embodiment, the infrastructure comprises three types of functional elements: probes, metrics and audits and a small number of primitive actions for manipulating these elements. The elements are connected by streams which store data for processing and transport data between functional elements. The primitive actions, which are duplicating and removing functional elements as well as splitting and joining metrics, are arranged such that the functional elements can be optimized dynamically in responses to changes in the service and/or the hardware without losing any data.12-31-2009

20100287361Root Cause Analysis for Complex Event Processing - Root cause analysis for complex event processing is described. In embodiments, root cause analysis at a complex event processor is automatically performed by selecting an output event from an operator and correlating the output event to an input event using event type and lifetime data for the input event and the output event stored in a data store. Embodiments describe how the lifetime data can comprise a start time and an end time for the event, and the correlation can be based on a comparison of the start and end times between the input and output events. Embodiments describe how the correlation algorithm used is selected in dependence on the event type. In embodiments, a complex event processing engine comprises a logging unit arranged to store in the data store an indicator of an event type and lifetime data for each output event from an operator.11-11-2010
