Abstract: A method which includes receiving a first signal from a first probe at a first location monitoring a rotating component, wherein the first location defines a cross-sectional plane that is perpendicular to the axis of rotation of the rotating component. The method further includes obtaining a vibration model and generating, by a computer processor, a virtual signal at a second location on the machine, where no second probe is present. The second location is in the same cross-sectional plane as the first location and is angularly offset by an angle from the first location. The method further includes performing a plurality of signal processing techniques based, at least in part, on the first signal and the virtual signal and transmitting a plurality of commands based, at least in part, on results of the plurality of signal processing techniques.

Abstract: A method for automatic diagnosis of a mechanical system of a group of mechanical systems sharing mechanical characteristics includes obtaining data relating to a vibration. The vibration-related data is acquired by a portable communications device configured to communicate with a remote processor. The processor automatically diagnoses the mechanical system by applying a relationship to the obtained vibration-related data. The relationship is based on sets of vibration-related data previously obtained from the mechanical systems. Each set of vibration-related data relates to vibrations of a mechanical system. The relationship is further based on sets of operation data previously obtained for mechanical systems of the group. Each set of operation data indicates a previous state of operation of a mechanical system. Each of the previous states of operation is associated with at least one of the previously obtained sets of vibration-related data.

Abstract: In a general aspect, a method can include applying. by a motor controller, a filter to a signal indicating rotational speed of an electric motor to detect an order of vibration of the electric motor to be attenuated. The method can also include providing the filtered signal to a proportional derivative controller, and generating, by the proportional derivative controller, an attenuation signal for attenuating vibration associated with the detected order of vibration. The method can still further include combining the attenuation signal with a torque command signal to produce a combined torque command signal. The torque command signal can indicate an amount of torque requested from the electric motor. The method can further include producing torque with the electric motor based on the combined torque command signal.

Abstract: Systems and methods are disclosed for identifying one or more vibration mechanisms or other mechanism associated with tool failure. In one example, a machine learning data system comprises a data pre-processing module, a machine learning training module, and a predictive module. The pre-processing module analyzes dynamic sensor input to identify one or more vibration mechanisms associated with a downhole tool. The machine learning training module identifies a correlation between dynamic sensor data and failure data for a plurality of downhole tools. The predictive module correlates the one or more vibration mechanism with tool failure or performance.

Abstract: There is provided a method of, and a corresponding system for, detecting an event related to vehicle integrity, such as an oblique angle or side swipe type crash. The method may include using a microphone to transduce sound into an analog audio signal, and then using an analog signal processor analogically transforming said analog audio signal in the time-frequency domain, including dividing the audio signal into a plurality of time segments, and each time segment into a plurality of signal components in a plurality of predetermined frequency bands. Such time-frequency spectrogram can be evaluated by the signal processor in order to detect vehicle integrity-related events. Accordingly, the system only requires ultra-low power, since no (analog) to digital conversion is required. This is advantageous in applications such as battery powered continuous vehicle monitoring. The method may also be carried out recurring to digital signal processing, that is in the digital domain.

Abstract: A vibration dose measurement apparatus 10 for an operator's hand 1 comprises a sensing assembly 20 connected to a control unit 25. The sensing assembly 20 comprises an accelerometer 21, gyroscope 22, and gripping force sensor 23 and may be packaged within a protective housing (not shown). By monitoring output of the sensor assembly 20, the vibration dose experienced by the hand 1 can be estimated. In the present invention, the provision of gripping force sensor 23 allows for vibration dose measurement to be adjusted based on the output of gripping force sensor 23. This can therefore take into account the force applied by an operator in gripping machinery, which can impact significantly on the effective vibration dose.
