Abstract: A system and method for aligning a target to a vehicle for calibration of a sensor equipped on the vehicle includes multiple non-contact wheel alignment sensors configured for use in determining the orientation of tire and wheel assemblies of the vehicle. A target adjustment frame includes a target mount moveably mounted on a base frame, and includes multiple actuators configured to selectively move the target mount relative to the base frame, where the base frame is in a known orientation to the non-contact wheel alignment sensors. A computer system selectively actuates the actuators to position a target relative to the vehicle, with the target mount being moveable about a plurality of axes based on the determination of the orientation of the vehicle relative to the target adjustment frame to position the target relative to a sensor of the vehicle whereby the sensor is able to be calibrated using the target.

Abstract: A non-contact sensor for determining orientation of an object, such as a tire and wheel assembly of a vehicle, includes a projector assembly having a light emitter, a lens assembly and a mask, with the mask including mask apertures and the light emitter configured to project light through the lens assembly and mask apertures and onto the object, and with the mask apertures creating a light pattern of projected light onto the object. The sensor also includes an imager configured to image reflections of the light pattern from the object, and a processor. The projector assembly and imager are angled with respect to one another, and the processor is configured to process imaged reflections of the light pattern to derive the orientation of the object, such as the alignment orientation of the tire and wheel assembly.

Abstract: A substrate patterning method including the steps of spraying ink on a surface of a substrate, the spraying of the ink resulting in an overspray of excess ink past an edge of the substrate; changing a temperature of the excess ink to cause a change in a viscosity of the excess ink; and removing the excess ink having the changed viscosity.

Abstract: Embodiments of apparatuses and methods for removal of ink buildup are generally described herein. Other embodiments may be described and claimed. In an embodiment, a chuck assembly to support a semiconductor substrate is provided. The chuck assembly includes a chuck, a trough disposed below the chuck, and a heater proximate to the trough. The chuck supports the semiconductor substrate while the trough collects an overspray of excess ink sprayed past an edge of the semiconductor substrate. The heater heats the trough.

Abstract: An improved apparatus for forming three-dimensional objects using multiple chambered resin vats and a photopolymer resin leveling system to permit concurrent use of multiple, photopolymer build materials and easy change over of resin vats is disclosed. The apparatus ensures the same level of photopolymer resin is maintained in each chamber during multiple chambered vat use.
