摘要： Methods for measuring the diameters of transparent filaments with high precision, e.g., RMS standard deviations of less than 0.02 microns, are provided. The methods involve determining the average spatial frequency .omega. of the far-field interference pattern produced by illuminating the filament with a beam of laser light. The average spatial frequency is determined by performing a fast Fourier transform (FFT) on the interference data to obtain a coarse estimate for the average and then performing a set of discrete sequence Fourier transforms (DSFTs) in the region of the coarse estimate to obtain the desired high precision estimate of the average. Efficient on-line processing procedures are provided so that real time measurements can be performed on, for example, a moving optical waveguide fiber, at rates of 500 measurements/second and above.

摘要： An apparatus for crimping electrical connectors to cables. The apparatus generally has a ram, an anvil, an electrical ram position sensor, and a computer for at least partially controlling movement of the ram relative to the anvil. The computer can use the position sensor for monitoring the position or location of the ram. The apparatus can have a hydraulic system for moving the ram relative to the anvil and a hydraulic system deactivation valve with a plunger, an extension, means for biasing, and a computer controlled limiter for limiting movement of the plunger and/or extension. The apparatus can also have a pressure sensor for sensing pressure in the hydraulic drive system including two electrical switches and two plungers suitably connected to the hydraulic drive system and adapted to be moveable by hydraulic system pressure at different hydraulic system pressures such that the different hydraulic system pressures can be communicated to the computer by the plungers activating the electrical switches. In a preferred embodiment the apparatus is provided as a hand-held and hand operated crimper with a ram position sensor, a hydraulic drive system, an electrical hydraulic system pressure sensor, a hydraulic system deactivation valve, and a computer connected to the sensors and the valve for at least partially controlling operation of the crimper.

摘要： A crimping apparatus and method for crimping electrical connectors to cables. The apparatus can automatically sense the size of a connector and can automatically determine a minimum acceptable distance of work travel in relation to the size of a connector. The apparatus can crimp articles and control the movement of an indentor by use of a computer. The apparatus can sense predetermined crimping information and at least partially record crimping information. The apparatus can determine the occurrence of a bad crimp. The apparatus can monitor predetermined characteristics of the crimper. The apparatus can sense free travel movement of an indentor and determine appropriate work travel movement of the indentor relative to sensed free travel movement. The apparatus can sense free travel movement of an indentor and compare sensed free travel movement to a stored memory of potential free travel movements and connector sizes. The apparatus can have a computer controller for, at least partially controlling a hydraulic drive system. The apparatus can have a diagnostic monitor for use in evaluating both past and present operation of the system. An apparatus is disclosed for determining indentor work travel movement of crimping apparatus and a method of controlling a system for hydraulically crimping electrical connectors is also disclosed.
