Abstract: A data-analyzing unit monitors and/or analyzes events on an information bus. The data-analyzing unit comprises an event recognition unit with one or more comparators coupled to the information bus and a sequencer state machine for determining sequential dependencies of events, whereby a state of the sequencer state machine depends on the history of information as provided thereto. The data-analyzing unit preferably comprises one or more counters coupled to the event recognition unit, thus allowing an analysis of data and/or events on the information bus. The data-analyzing unit may also comprise one or more memories coupled to the event recognition unit, thus providing a trace memory. In a preferred embodiment, the event recognition unit of the data-analyzing unit provides customized rules for monitoring defined event sequences of event behaviors thus allowing the monitoring of defined event sequences of event behaviors and possibly the drawing of conclusions therefrom e.g.

Abstract: In a multiplex communication method for implementing multiplex communication between a plurality of circuit units, a format of a transmitted data signal not only is formed of serial data consisting of first data, second data that has the same content as the first data, and a parity that indicates the number of logical 1s or logical 0s forming the first data and the second data is even or odd, but also selects as regular data in such a manner that when the transmitted data signal is received, if the first data and the second data are compared with each other and judged to be coincident with each other from the comparison, then the coincident data is selected as the regular data and that if the first data and the second data are judged to be different from each other from the comparison, then a logic of the parity is checked and either the first data or the second data corresponding to the logic of the parity is selected as the regular data.

Abstract: A system for encoding and decoding a binary encoded text message using coxt-based error detection and correction implements the stops of: a) defining a dictionary of m dictionary words, W.sub.i, where each dictionary word is assigned a unique binary code word, represented by a series of bits, and an identifier, IDFR.sub.i such that for any two words W.sub.p and W.sub.q from the dictionary, if IDFR.sub.p =IDFR.sub.q, then the binary code word for the word W.sub.p differs from the binary code word for the word W.sub.

Abstract: A system comprising devices connected via a 1394 serial bus solves a problem that if omission of data packet occurs in isochronous transfer capable of high-speed data transfer, only data without the omitted data packet is sent to a transfer destination. A recording/reproduction device 101 repeatedly sends image data stored in a storage medium by the isochronous transfer, and a printer 102 receives the image data repeatedly sent by the isochronous transfer. If a data packet has been omitted in the received data, the omitted data packet is obtained from the data repeatedly sent by the isochronous transfer, thus the printer 102 can print an image based on the complete image data.

Abstract: A corrected digital response signal is generated from a corrupted transponder response signal by receiving the response signal an odd number of times, greater than one, and sampling each received response signal a predetermined number of times. Then, the sample values from each transponder response signal are compared to one another and a majority sample value is obtained. The majority sample value is the value ordained by the majority and therefore represents the corrected response signal value. Alternatively, if time does not permit reception of more than one transponder response signal, additional response signals may be generated from the originally received response signal by shifting the received response by a predetermined number of samples to the right and by shifting the received response by a predetermined number of samples to the left to generate second and third response signals.
