Patent number: 10355920Abstract: A machine monitoring system uses generically defined collection definitions, acquisition definitions, and measurement definitions to define machine data to be collected by machine monitoring devices and other data sources in a unified and device/source independent manner. Configuration software of the machine monitoring system defines data to be collected for a particular machine in such a manner that multiple different types of monitoring devices or data sources can each interpret the data definitions and provide the same type of data back to the software system. Thus, the data to be collected is defined once by the configuration software, and the data definition is interpreted internally by each monitoring device or data source. This greatly simplifies the monitoring system and provides the advantage that new monitoring devices can be added to the system to collect data without impacting the software configuration of the data required.Type: GrantFiled: July 13, 2016Date of Patent: July 16, 2019Assignee: Computational Systems, Inc.Inventors: Christopher G. Hilemon, Anthony J. Hayzen, Thomas E. Nelson, Michael D. Medley

Patent number: 10222295Abstract: The system implements an algorithm that allows an integrator providing a vibration velocity measurement to be disabled automatically in order to do a PeakVue measurement. When the PeakVue measurement is required, the integrator is disabled and the last Overall velocity measurement is maintained. Once the PeakVue measurement is complete, the integrator is re-enabled and the Overall measurements resume.Type: GrantFiled: November 2, 2015Date of Patent: March 5, 2019Assignee: Computational Systems, Inc.Inventor: Michael D.

Patent number: 9784601Abstract: A system is described for time synchronizing digitized measurement signals, such as vibration signals. The digitized signals, which are acquired asynchronously by multiple distributed measurement units, indicate the operational condition of a machine or a process. To measure the phase of the digitized signals relative to a pulse tachometer input, the time between the leading edge of the tachometer pulse and the digitized samples is measured. To achieve phase-coherent synchronization across the distributed measurement units, a local synchronization signal is embedded into the data produced by the measurement units. The systems uses the synchronization signal to align the data in post processing, which phase aligns the data and aligns the data in absolute time. The synchronization signal may be encoded with a timestamp to provide additional timing information.Type: GrantFiled: November 20, 2014Date of Patent: October 10, 2017Assignee: Computational Systems, Inc.Inventors: John W. Willis, Michael D. Medley, Anthony J. Hayzen, Deane M. Horn

Patent number: 9778080Abstract: Useful and meaningful machine characteristic information may be derived through analysis of oversampled digital data collected using dynamic signal analyzers, such as vibration analyzers. Such data have generally been discarded in prior art systems. In addition to peak values and decimated values, other oversampled values are used that are associated with characteristics of the machine being monitored and the sensors and circuits that gather the data. This provides more useful information than has previously been derived from oversampled data within a sampling interval.Type: GrantFiled: April 15, 2014Date of Patent: October 3, 2017Assignee: Emerson Electric (US) Holding Corporation (Chile) LimitadaInventors: Raymond E. Garvey, III, Joseph A. Vrba, Stewart V. Bowers, III, Robert D. Skeirik, Hermann Holtmannspötter, Michael D. Medley, Kevin Steele, Douglas A. Mann

Patent number: 9727050Abstract: A vibration data acquisition and analysis module is operable to be inserted directly into a distributed control system (DCS) I/O backplane, so that processed vibration parameters may be scanned directly by the DCS I/O controller. Because the process data and the vibration data are both being scanned by the same DCS I/O controller, there is no need to integrate numerical data, binary relay outputs, and analog overall vibration level outputs from a separate vibration monitoring system into the DCS. The system provides for: (1) directly acquiring vibration data by the DCS for machinery protection and predictive machinery health analysis; (2) direct integration of vibration information on DCS alarm screens; (3) acquisition and display of real time vibration data on operator screens; (4) using vibration data to detect abnormal situations associated with equipment failures; and (5) using vibration data directly in closed-loop control applications.Type: GrantFiled: July 24, 2015Date of Patent: August 8, 2017Assignee: Computational Systems, Inc.Inventors: John W.

Patent number: 5406125Abstract: A semiconductor device having a metalized via hole used when mounting and connecting semiconductor chips, such as microwave chips, digital chips, analog chips and the like, on a top portion of a metalized carrier substrate is described herein. Each chip includes electrical circuitry on a top portion thereof with the circuitry connected to one end of a transmission line. Another end of the transmission line is connected to a metalized via hole. The via hole passes from the top portion of the chip to a bottom portion of the chip. The chip when mounted on the substrate is positioned over the top portion of the substrate and lowered thereon either by hand or with a mechanical chip carrying device. The bottom portion of the metalized via hole is indexed over a top of one end of a transmission line on the top portion of the substrate with the indexing tolerance between the two interfacing surfaces in a range of 0.5 to 10 mils.Type: GrantFiled: April 15, 1993Date of Patent: April 11, 1995Assignee: Martin Marietta Corp.Inventors: Gerald E.
