Abstract: Nut retaining devices and related methods are disclosed. An exemplary nut retaining device may include a housing defining an interior receptacle, the housing including attachment structure configured for fixing the housing to a base structure; a nut received within the receptacle and having screw threads for engaging a threaded fastener; retaining structure engageable with the nut and retaining the nut within the receptacle; anti-rotation structure between the housing and the nut constraining the nut against rotation relative to the housing; the anti-rotation structure configured to provide a clearance movement between the nut and the housing in at least one of a rotation direction rotationally about the screwing axis of the nut, or an axial direction parallel to the screwing axis of the nut, or a radial direction relative to the axial direction that is parallel to the screwing axis of the nut.

Abstract: Automated methods and systems for machine monitoring are disclosed. Some embodiments, given by way of example, may include the processing of data associated with a machine by carrying out a time-frequency decomposition, by carrying out phase grouping, by carrying out cross-correlated time-frequency pseudo-distribution, and/or by carrying out peak detection on shared power in order to detect machine cycles. Some embodiments, given by way of example, may carry out a learning operation followed by a process-monitoring operation, thereby facilitating adjustment and operation with limited user interaction.
