Patent number: 10748406Abstract: A machine condition monitoring system employing a haptic feedback device. The haptic feedback device can be employed to notify an operator of an acquisition of a machine parameter measurement. The haptic feedback device can be integrated into a control unit of a condition monitoring device and/or a remote condition monitoring status receiving device. The haptic feedback device containing notification apparatus can be worn by the operator, thus providing immediate notification without requiring the Operator's undivided attention. The notification apparatus can be worn on the operator's waist, wrist, upper arm, ankle, neck, etc. The notification apparatus can also be stored within a pocket of a garment worn by the operator.Type: GrantFiled: July 2, 2015Date of Patent: August 18, 2020Assignee: Aktiebolaget SKFInventor: Johannes I.

Patent number: 6792360Abstract: Systems and methods for identifying the presence of a defect in vibrating machinery. An exemplary method comprises analysis of frequency spectrum vibration data of the machine. The method comprises deriving a harmonic activity index based on estimates of the energy associated with the frequency spectrum and the energy associated with the defect's harmonic series. The method may comprise deriving a value K by estimating a value M indicative of the energy of the defect's harmonic series and dividing M by the number of spectral lines corresponding to the defect's harmonic series. The method may further comprise deriving a value R by estimating a value Q indicative of the energy in the frequency spectrum data and dividing Q by the number of spectral lines of the frequency spectrum data. The method further comprises deriving the harmonic activity index based on the estimated K and R. Related systems for executing the methods are also disclosed.Type: GrantFiled: December 4, 2002Date of Patent: September 14, 2004Assignee: SKF Condition Monitoring, Inc.Inventors: Adrianus J. Smulders, Jim J. Wei, Johannes I. Boerhout

Patent number: 6789025Abstract: The condition of a machine is monitored with cyclic time averaging, a technique of allocating vibration energy to particular sources in a complex signal. The cyclic time averaging method is directed at processing time-domain vibration data of the machine to produce an averaged time waveform over a selected cyclic time period. Utilizing cyclic time averaging, the systems and methods analyze machine vibration signals to detect and evaluate specific sources of enemy contribution to the vibration energy of the machine. It is not necessary to employ a triggering signal to obtain the averaged time waveform.Type: GrantFiled: December 4, 2002Date of Patent: September 7, 2004Assignee: SKF Condition Monitoring, Inc.Inventor: Johannes I.

Sequences of extracted vibrational features are routed to a variable length output buffer for event detection.Type: GrantFiled: July 23, 2001Date of Patent: October 14, 2003Assignee: SKF Condition MonitoringInventors: Philip L. Maness, Johannes I. Boerhout

Publication number: 20030178515Abstract: A monitoring system for a crushing device that provides continuos and automatic monitoring. In one embodiment of the invention, the monitoring system monitors vibration signals and sensed temperature readings to determine whether the sensed data exceeds predefined thresholds and thereby signaling an possible alarm condition. In the event of the alarm condition, an idle detector in the monitoring system determines whether the crushing device is operating in an idle state. If the crushing device is in an idle state, an alarm is signaled for operator attention and optionally the crushing device may be automatically shutdown. The monitoring system may be used with any crushing device such as cone crushers, roll crushers, jaw crushers, and impact crushers or other type crushing devices.Type: ApplicationFiled: February 28, 2002Publication date: September 25, 2003Inventors: Johannes I.
