摘要： Control is switched from a first server to a second server in a fault tolerant system. The first and second servers are coupled with an expansion bus in an expansion box for communication with the expansion bus. An indication is provided to the second server to indicate the activity state of the first server. Communication between the first server and the expansion box is disabled if the indication indicates the first server is inactive. Communication between the second server and the expansion bus is disabled if the indication indicates that the first server is active. Communication between the second server is enabled if the indication indicates that the first server is inactive. The indication includes a heartbeat message transmitted periodically to the second server. The expansion bus includes a PCI bus.

摘要： A safety circuit for monitoring computer hardware that can create an unsafe condition if a failure occurs. The circuit includes a microprocessor, a keyword decoder, and a dynamic safety relay drive circuit. The microprocessor runs a set of internal tests which create a keyword made up of a series of bits. A particular series of bits indicates the desired operation of the microprocessor. On alternate generations of the keyword one bit in the series is inverted. The keyword decoder receives the keywords and outputs a 'true' signal if the keyword indicates the desired operation of the microprocessor, and 'false' signal if the keyword indicates otherwise. The output of the keyword decoder is transmitted to the dynamic safety relay drive circuit, and this signal will keep the circuit energized as long as its alternating. The position of the bit which is inverted is rotated through the keyword so that different bit paths through the keyword decoder may be tested.

摘要： A method of analysing a communication system to locate the source of a fault. The communication system comprises a signal carrying medium (9) coupled to a series of end station ports (2-6) which enable respective end stations (24) to transmit signals onto and receive signals from the medium and a controller (8) to control connection of end stations (24) to the medium via the ports (2-6). The method comprises disconnecting end stations (24) in series from the medium (9) in response to detection of a fault and then detecting whether the fault still exists. A fault analyzer (10) adapted to respond to the detection of a fault causes the controller (8) firstly to disconnect an end station (24) which has previously been characterised as the most likely source of a fault. The controller (8) may disconnect groups of end stations (24) and reconnect subgroups if no fault is present in the group which was not disconnected until the faulty end station is identified.

摘要： Bei dem erfindungsgemäßen Verfahren zur Erkennung von fehlerhaften Vorhersagen in einer neuromodellgestützten oder neuronalen Prozeßregelung erfolgt die Verarbeitung der Prozeßmeßgrößen in mindestens zwei getrennten Verarbeitungssträngen, von denen jeder Verarbeitungsstrang ein mit gleichen Daten trainiertes neuronales Prozeßmodell (1 bis 5) bzw. einen mit gleichen Daten trainierten neuronalen Prozeßregler enthält, wobei die neuronalen Prozeßmodelle bzw. Prozeßregler aber unterschiedlich ausgebildet sind. Sie können sich in ihren Initialisierungsparametern, z.B. in den Gewichten ihrer Neuronen, und/oder in ihrer Topologie und/oder in ihrem Typ voneinander unterscheiden. Die Ausgangsgrößen der einzelnen neuronalen Prozeßmodelle oder Prozeßregler werden miteinander verglichen und aus den Abweichungen der Ausgangsgrößen wird auf fehlerhafte Vorhersagen geschlossen. Eine Aussage über die Größe des Vorhersagefehlers kann nach den bekannten statistischen Verfahren gemacht werden. Hierzu wird in einem Bewertungsmodul (10) aus den Ausgangsgrößen der neuronalen Prozeßregler (1 bis 5) bzw. Prozeßmodelle die Standardabweichung oder Streuung berechnet und mit einem vorgegebenen Grenzwert verglichen. Bei Überschreiten des Grenzwertes wird dann auf eine fehlerhafte Vorhersage geschlossen, so daß sich gefährliche oder suboptimale Betriebszustande ausschließen lassen.

摘要： A portable electronic unit, such as a defibrillator, includes an autotest system for automatically self-testing various electrical components within the unit during quiescent periods. The autotest system includes an autotest routine that performs an extensive array of rigorous yet time-consuming tests that are impractical to perform during normal modes of operation of the unit. A real-time clock can be set to initiate the autotest routine at a time when the unit is unlikely to be used for its normal mode of operation. The autotest system provides a strip chart printout of the results of the various self-tests performed on the unit, and provides messages on a visual display of any error conditions. If the autotest system detects a needs service malfunction, the operator must acknowledge the error with an input to the unit before the unit will enter into its normal mode of operation. If the autotest system detects a service mandatory malfunction, the unit will discontinue any normal mode of operation until the malfunction is corrected. The autotest system immediately discontinues the autotest routine upon power-up of the unit by an operator for use of the unit in its normal mode of operation.
