A cable bushing fitting machine includes: a fitting region; a mandrel disposed at said fitting region, said mandrel being hollow to receive a cable therethrough; a first rotatably mounted stripping jaw arranged in the fitting region; a second rotatably mounted stripping jaw arranged in the fitting region; a drive configured to mount cable bushings onto cable by successively disposing respective ones of the cable bushings onto the mandrel, feeding the cable through the mandrel, and executing a relative movement between the mandrel and the first and second rotatably mounted stripping jaws to locate the respective cable bushings onto the cable; a camera directed toward the fitting region to capture images of the respective cable bushings located on the cable; and at least the first rotatably mounted stripping jaw having a rotation axis, the first stripping jaw rotation axis being laterally offset from an optical axis of said camera by a distance sufficient to permit the camera unimpeded views of cable bushings in the fitting region when the first stripping jaw is at least to a first selected extent opened.

An electronic device includes an electronic circuit board containing a processing element and a vision sensor. A carrier frame is used to support the electronic circuit board. An optical element is positioned over the sensor and supported by the carrier frame. The electronic circuit board is bent to reduce the length, thickness and/or width of the electronic device, without increasing the others of the length, thickness and/or width of the electronic device.

A WDM multiplexing/demultiplexing system includes a de-multiplexer configured to separate and guide light beams from an incident ray having a plurality of wavelengths to corresponding lenses on an optical device, a multiplexer configured to guide light beams from optical transmitters having various wavelengths through the corresponding lenses on the optical device and combine the light beams, a lens array including the corresponding lenses to receive and/or transmit the light beams from or to the de-multiplexer and multiplexer, and a light beam collimator configured to function with the multiplexer and de-multiplexer. The light beams received or transmitted by the light beam collimator and the light beams transmitted or received from or to the multiplexer and de-multiplexer are collinear. The light beam collimator and multiplexer/de-multiplexer can be easily positioned to predetermined or designed positions, thereby providing light beams output through the lenses in a plastic optical device. The WDM system advantageously reduces optical signal loss, while increasing the assembly yield.

An automated grommet installer and methods of installing a grommet. The installer and methods are capable of seating a grommet in an aperture of a window and facilitating correct alignment of the grommet within the window. Grommets are used to support and seal around a window wiper attached to a window. Typically, grommets are asymmetrical to match the curvature of the window. Embodiments of the described installer maintain grommet orientation while inserting the grommet in the window, quickly and efficiently installing the grommet. In embodiments the installer includes a system for identifying an incorrectly loaded grommet prior to installation and alerting an operator. In other embodiments, the installer includes a positioner that positions the grommet proximate to the window for installation and a gripper having one or more fingers reach through the window aperture, engage the grommet, and draw it into position, seated in the window.

A method is provided for ensuring and/or checking the quality of a crimping using a crimping machine for crimping a cable with a contact sleeve and using a first optical sensor for detecting and/or recording first image data of the contact sleeve and using an evaluation electronics system. The method includes detecting the first image data of the contact sleeve by the first optical sensor; carrying out, via the evaluation electronics system, a first comparison of the first image data of the first optical sensor with first reference data of a predetermined contact sleeve; checking the first comparison for the presence of a predetermined first criterion; and, if the predetermined first criterion is satisfied, outputting a first signal. The detection of the first image data and the first comparison and the checking for the first criterion and the output of the first signal are carried out before the cable is crimped with the contact sleeve. A crimping machine suitable for carrying out the above method is also provided.

A workpiece processing method includes a carry-in step of carrying a workpiece into the field of view of a magnifier, a work step of performing predetermined work on the workpiece based on an image provided via the magnifier, and a carry-out step of carrying the workpiece out of the field of view of the magnifier. A robot performs at least one of the carry-in step and the carry-out step as well as the work step.
