An abrasion inspection apparatus includes: a first imaging unit that is installed on a side of a track, a vehicle traveling along the track, a guide wheel being installed on a side of the vehicle, the first imaging unit imaging an inside of the track via a telecentric lens; a second imaging unit that is installed in a vehicle traveling direction with respect to the first imaging unit on the side of the track and images the inside of the track via a telecentric lens; an image acquisition unit that acquires an image which is an image of a boundary of the guide wheel captured by the first imaging unit and is an image of a boundary on a first direction side in the vehicle traveling direction and an image which is an image of the boundary of the guide wheel captured by the second imaging unit at the same time as the capturing of the image by the first imaging unit and is an image of a boundary on an opposite side to the first direction side; and a guide wheel detection unit that detects an abrasion situation of the guide wheel according to a position of a boundary indicated in the images acquired by the image acquisition unit.

A method of concurrently determining length and diameter of nanowires. Nanowires are provided onto a support. A chosen illumination of the nanowires on the support is provided. An image of the nanowires on the support is obtained. A length of each nanowire is calculated by an image processing program. A relative diameter of each nanowire is calculated based on an integrated intensity of light scattered per unit length from each nanowire.

An apparatus that melts and monitors sleeves for installation onto shielded cables. The apparatus includes a heat source for melting the sleeve, cable supports for supporting the cable during the melting process, a sensor system that is configured to measure a dimension of the sleeve during melting, and a computer that is connected to receive sensor data from the sensor system and send heater control signals to the heat source. The computer is configured to receive dimensional data from the sensor system, monitor that dimensional data by performing a dimensional analysis, and then deactivate or remove the heat source in response to dimensional analysis results indicating that the sleeve is fully melted (in the case of a solder sleeve) or only fully shrunken (in the case of a dead end sleeve) onto the cable.
