Abstract: An improved method is described for measuring a dimension (e.g. diameter) of a non-toothed tool, for example a grinding tool such as a diamond coated burr. The method may be implemented on a machine tool, such as a lathe, machining centre or the like. The method comprises passing a beam of light from a transmitter to a receiver. The receiver produces a received intensity signal related to the intensity of received light. Analysis of variations in the received intensity signal is performed when a rotating tool is moved relative to the light beam to enable a dimension of the tool to be measured. In particular, it may be determined when the received intensity signal has crossed a threshold for at least a defined duration, the defined duration being less than the time taken for one complete rotation of the tool.

Abstract: In sharp contrast to the prior art, a fallen tree detection and localization method based on distributed fiber optical sensing (DFOS) technique and physics informed machine learning is described in which DFOS leverages existing fiber cables that are conventionally installed on the bottom layer of distribution lines and used to provide high-speed communications. The DFOS collects and transmits fallen tree induced vibration data along the length of the entire overhead lines, including distribution lines and transmission lines, where there is a fiber cable deployed. The developed physics-informed neural network model processes the data and localizes the fallen tree location along the lines. The location is interpreted in at least two aspects: the fallen tree location in terms of the fiber cable length; and the exact cable location (power cable or fiber cable) that the fallen tree mechanically impacts.
