摘要:
The present invention discloses a method and a chip card for starting and executing an operating system of a controller of a portable data storage medium, wherein the data storage medium comprises at least one antenna coil which is connected to the at least one controller, wherein an output impedance of the antenna coil is not matched to an input impedance of the controller. The controller first of all executes a utility program in order to check whether electrical energy provided by the antenna coil is sufficiently large to start and execute the operating system on the controller. If the check by the utility program revealed that it is possible to start and execute the operating system with the energy provided, the controller starts the operating system and executes the latter.

An LCD support system includes structure adaptable to selectively accommodate a central processing unit, a plurality of media drivers and a plurality of viewing screens so that no external electrical cabling is needed to couple the various subcomponents to one another. The plurality of viewing screens are selectively positioned along vertival and/or horizontal arms extending from the structure. Slidable brackets having viewing screens coupled thereto are movable along the arms of the structure to customize the multiple viewing screen arrangment according to a desired spacing and/or setup. A central procesing unit may be readily detached from a first computer system having a first viewing screen configuration and attached to a second computer system having an alternative viewing screen configuration. The present invention provides a very compact, uncluttered means for supporting one or more LCD screens.

The present invention relates to a processor having means for dynamically monitoring and modifying the operating parameters of a processor, such as, for example, the frequency of a clock signal used to drive various functional elements of the processor according to the operating capabilities or operating environment of the processor. Advantageously, the performance of the processor can be varied, or maintained at a maximum, as well as being made to operate at a higher frequency than would previously have been safely possible.
摘要:
Es wird ein Verfahren zur Überprüfung eines Schnittstellenbausteins vorgeschlagen, wobei nach Aufforderung eines Tests durch einen Prozessor mit einem Datentelegramm der Schnittstellenbaustein abgespeicherte Werte, die Sensorwerte repräsentieren mit einem zweiten Datentelegramm an den Prozessor zurückgibt. Mit diesen festen Sensorwerten kann der Prozessor die Funktion des Schnittstellenbausteins und seinen eigenen Algorithmus überprüfen. Ein Sicherheitsbaustein, der ebenfalls die Sensorwerte aufnimmt, überprüft auch seine Funktion damit, da der Sicherheitsbaustein ein redundanter Hardwarepfad zum Prozessor (1) ist und als Plausibilitätsüberprüfung für die Auslöseentscheidung von Rückhaltemitteln verwendet wird. Der Schnittstellenbaustein wird in einen Testmodus versetzt, sobald er das erste Datentelegramm vom Prozessor erhält und unterdrückt dann die Übertragung von den echten Sensorwerten, die von angeschlossenen Sensoren empfangen wurden.
