Title: Process for determining competing cause event probability and/or system availability during the simultaneous occurrence of multiple events
Inventor: TAN JONATHAN SAMUEL
IPC: G05B23/02
Filed: 2003-10-03
Abstract: A method for determining the probability of observing an event. The event may occur either alone or in combination with one or more other events. The method may be non-combinatorial in that it does not require a separate calculation for each simultaneously occurring event, thereby significantly reducing computation time for complex systems having multiple events. Further, the method may be numerically reversed to calculate the probability of an event occurring based upon the number of observations. The method is particularly useful for predicting availability, component failure, or the possibility of a false start in production systems.

Filed: 2003-06-10
Abstract: The invention relates to a device 22 comprising a communication system transceiver 40 for exchanging signals in a first frequency band and a receiver 30 for receiving signals in a second frequency band. In order to improve the performance of the receiver, it is proposed that the device comprises a processing portion 34 detecting the presence of signals interfering with the signals in the second frequency band. The processing portion further determines a timing pattern for interfering signals based on a timing information which is indicative of the timing for transmissions employed by the transceiver 40. The processing portion then causes a manipulation of signals reaching the receiver 30 during intervals defined by the determined timing pattern, in order to reduce a performance degradation due to interfering signals originating from a transmitter 21 employing the same timing for transmissions as the transceiver 40. The invention relates equally to a corresponding method.
