Abstract: A method of provisioning cards in a rack mount system, by selecting a desired configuration file from a library of configuration files, and copying the configuration file into a memory device. The memory device is inserted into the rack mount system and powered up. Whereupon the configuration file automatically and without any further user intervention provisions a card of the rack mount system.

Abstract: A method for configuring components in a computing system. A selected one of the components is designated as a primary component, the other components thereby automatically adopting a status of secondary component. The designation of the primary component is stored in a first memory that is accessible by at least one of the primary component, at least one secondary component, and the computing system. Upon occurrence of a predetermined computing system event, the first memory is read to determine the designation of the primary component. A configuration file from a second memory is automatically copied to a memory of at least one secondary component, thereby creating a new configuration file in the at least one secondary component.

Abstract: Two speed measurements of a moving body are generated using a single signal. A sensor generates a composite signal having a series of pulses where each pulse is generated when an element on a moving body passes the sensor. A sensor conditioning unit decouples the composite signal to generate a first conditioned sub-signal having only an AC signal corresponding to an AC component of the composite signal and a second conditioned sub-signal corresponding to the composite signal that may have either or both AC and DC components. A timer/counter input unit computes a first speed measurement by determining a count of pulses in the first conditioned sub-signal and a first time period or the time period of one pulse. The second conditioned sub-signal is transmitted to an analog-to-digital converter (ADC) and is sampled at a sampling rate to generate a sampled second conditioned sub-signal.

Abstract: An identification circuit for determining a chassis identification and a slot identification within the chassis using a single reading. The circuit includes a first electrical component associated with a first slot of a first chassis, where the first electrical component has a first value. A second electrical component is associated with a second slot of the first chassis, where the second electrical component has a second value that is different from the first value. A removable card has a third electrical component with a third value, where the removable card inserts into a selected one of the first slot and the second slot of the first chassis. A measuring circuit measures an interaction between the third electrical component and the associated one of the first electrical component and the second electrical component, where the interaction has a fourth value. The fourth value of the interaction identifies both the first chassis and the selected slot into which the removable card is inserted.

Abstract: An instrument for performing order analysis on a rotational machine. An input module receives periodic motion data, and machine characteristic data that is associated by time with the periodic motion data. A processor module receives the periodic motion data and the machine characteristic data, applies a Goertzel module to the periodic motion data and the machine characteristic data, and thereby creates an order data set comprising magnitude of machine characteristic data versus order of normalized periodic motion data.

Abstract: Sensors monitor parameters of a machine and generate sensor signals that are transmitted to a plurality of signal analyzers. A microprocessor in each signal analyzer analyzes a sensor signal and generates an event signal when the sensor signal meets predetermined criteria indicating that the machine is operating abnormally. A circular buffer is connected to receive and record data corresponding to a sensor signal. When the signal analyzer generates an event signal and a capture trigger is created, the data from the circular buffer is transmitted and stored in the nonvolatile memory. Both pre-event data and post-event data are stored in the nonvolatile memory in a selected ratio of pre-event and post-event data. Data lines connect each signal analyzer in a group of signal analyzers, and data corresponding to each signal analyzer in the group is stored into the nonvolatile memory when an event signal is created by a signal analyzer in the group.

Abstract: A single universal sensor interface of a machine monitoring system is capable of providing a sensor supply voltage range that is selectable from 0V to ?30V, 0V to +30V, or +/?15V, and a sensor signal input range of ?30V to +30V to accommodate various types of sensors typically used in machine monitoring applications. Some embodiments of the interface also provide a buffered, unaltered sensor signal output.

Abstract: A centralized system for communicating with machine instruments, includes a processor, a memory, a communication port, and a communication module. The communication module has a set of sockets for communicating through the communication port, and a library of plugins, where each plugin is associated with at least one of the machine instrument types and firmware version. A plugin manager communicates with a selected one of the machine instruments and searches the plugin library to find a plugin that is compatible with the type and firmware version of the selected machine instrument. A compatible plugin is associated with the selected socket, such that the compatible plugin interprets communication between the centralized system and the machine instrument. The associating occurs without altering associations between other plugins and sockets and interrupting communications between the centralized system and any of the other machine instruments.

Abstract: Redundant detection of a rotational direction of a body having a rotary axis, in particular of a drive shaft of a turbine, is performed using at least one evaluation unit designed for evaluating at least three signals from three sensors arranged offset around the rotary axis. One period of a flank signal of a signal used as the primary signal is evaluated with the applied signal of one (Digital2) of the two signals not used as the primary signal for detecting the rotational direction. An error detection unit is designed for detecting the number of flanks of the signal initially used for detecting the rotational direction during the period. In the event of an error detection, the further rotational direction is detected in the evaluation unit on the basis of the other (Digital3) of the two signals.
