摘要： A system and method to detect ground faults in a multi-processor communication system that includes a communications link that extends between the processors. The processors isolate different sections of the link. Measurements made with different isolated sections establish the location of the fault. The processors can also make measurements of the link to establish the magnitude of a shunt impedance on the link. Where an abnormal value of shunt impedance is detected, the respective devices can activate or deactivate solid state isolation circuitry to disconnect a section of the link exhibiting the abnormal level of shunt impedance.

摘要： A multi-processor communication system includes a plurality of processors in bidirectional communication with one another. One processor can transmit a message to an intended recipient. The message can be correctly received by other processors. In the event that the intended processor does not correctly receive the message and transmits a failure indicating message, the other processors, upon detection of the failure will retransmit the message. Ambient condition sensors can be coupled to some of the processors.

摘要： A communication protocol facilitates transmission at maximum rates for various types of cables. Signal to noise characteristics are improved by using voltage waveforms. The protocol can be used to transmit information between a common control unit and a plurality of spaced apart devices coupled thereto. Alternately, the protocol can be used for transmission of information between devices. The common control unit transmits clock pulses, while in a low impedance state. The devices respond to the clock pulses and transmit data on the communications link, in a low impedance state, when the common control unit has assumed a high impedance state. Clock signals and data signals are separated to improve signal to noise characteristics by transmitting same with opposite polarities. A clock detection circuit responds to the polarity of the clock pulses. A data detection circuit responds to the polarity of the data pulses. One or more features of transmitted signals can be used to implement one or more synchronized functions.

摘要： A dynamically adjustable communication system and method automatically adjust transmission rates of discontinuous waveforms from one signal level to another for the purpose of optimizing a quality parameter of a transmitted signal. Circuitry coupled to the transmission medium provides feedback to transmitter circuitry for the purpose of adjusting at least one of a rise time and a fall time parameter of a transmitted signal for the purpose of enhancing transmission quality. Transmission rate can also be automatically adjusted to maximize data rate and minimize errors.

摘要： A system and method for establishing an alarm threshold for each member of a plurality of detectors or sensors includes storing a value returned from each detector indicative of a clear air condition. A second value returned from each detector indicative of a test condition is stored. The stored values are combined with a common detector characteristic value to produce a unique alarm theshold for each detector. The determined alarm thresholds can be stored for subsequent use. Subsequently, a value returned from a detector indicating a current ambient condition can be compared to that detector's previously determined alarm threshold. If the currently returned value from the detector exceeds the predetermined alarm threshold, an alarm condition can be indicated.
