摘要： Methods and systems for determining longitudinal position of an elongated web are described. Sensors are used to detect one or more substantially continuous fiducial marks disposed longitudinally on the web. The sensors generate signals associated with the fiducial marks. A position detector receives the signals and determines a longitudinal position of the web using the sensor signals. The fiducial marks may be periodic fiducial marks, such as sine and/or cosine marks on the web and/or may be piecewise continuous marks. The coarse longitudinal position of the web can be determined based on periodically recurring features of the fiducial marks. The fine longitudinal position can be determined based on continuous portions of the fiducial marks between the periodically recurring features.

摘要： Web tension in web material passing through a web transport system is determined in real time using position sensors coupled to driven rollers that define a beginning and an end of a tension zone. The position sensors on the rollers provide information related to the amount of strained web material that has been added and subtracted from the web material present in the tension zone. The amount of web material added to, subtracted from and present in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the present amount of unstrained web material present in the tension zone. Because the length of the tension zone is both fixed and known, the tension in the web material is determined from the present amount of unstrained web material in the tension zone.

摘要： Approaches for enhancing web position determination involve phase locking a web movement encoder signal to a sensed web fiducial signal. Fiducials disposed along a longitudinal axis of a substrate are sensed and corresponding sensor signals are generated. An estimated web position is provided by one or more encoder signals. The phase difference between the sensor signals and the encoder signals is calculated and the web position error is determined based on the phase difference. The web position error signal can be fed back to adjust the encoder signals which improves the accuracy of the web position determination.

摘要： Methods and systems for indicating the displacement of a flexible web are described. An elongated, flexible web includes an integral scale having scale features configured to modulate energy directed towards the web. A transport mechanism provides relative movement between the web relative to a transducer. The transducer detects energy modulated by the scale features and generates a signal indicting a continuous web displacement based on the modulated energy.

摘要： Methods and systems for forming a displacement scale comprising TIR prisms on a substrate are described. A system for forming the displacement scale includes one or more rollers having a pattern of total internal reflection (TIR) prism features in negative relief. As the rollers are rotated, the scale is formed on the substrate. The rollers may also include pattern features in negative relief. Rotation of the rollers simultaneously forms the displacement scale and the pattern features on the substrate. The TIR prism features of the displacement scale may be oriented to provide measurement of one or more of lateral displacement, longitudinal displacement and angular displacement.

摘要： Methods and systems for determining the displacement of a substrate using a scale comprising TIR scale features are described. A scale that includes a number of total internal reflection (TIR) prisms as scale elements is disposed on the substrate. Light directed towards the scale is modulated by the TIR prisms. A signal indicating a displacement of the substrate is generated based on the modulated light. The signal 10 may be used to determine the web position, to control web movement, and/or to measure various web parameters.

摘要： Fiducials having substantially continuous portions made on a substrate allow the position of the substrate to be determined. An approach for making fiducials involves moving first and second fiducial devices together back and forth across the substrate along a trajectory having a component along the lateral axis of the substrate while the substrate and the first and second fiducial devices are in relative motion along the longitudinal axis of the substrate. The first fiducial device operates to make one fiducial on the substrate during the movement along the trajectory and the relative motion. The second fiducial device operates to make another fiducial on the substrate during the movement along the trajectory and the relative motion. The fiducials may be formed so that they have a constant spatial frequency with the first fiducial being out of phase with respect to the second fiducial.

摘要： Injection molding parts onto a carrier web located between mold halves, each mold half having a cavity, resulting in molded articles having parts on both sides of the carrier web. Polymer flow into the cavities is assisted by application of ultrasonic energy to the mold. After the molding operation, mold halves are separated, and the carrier web is advanced, or indexed, to a next position for another molding sequence. Articles produced include lenses with part of the carrier web between lens halves, and a carrier web bearing an array of molded parts.
