Abstract: A method for rating drivers includes associating each of a plurality of segments of a route with a respective one of a plurality of segment types. For each of the plurality of drivers, a respective segment type value associated with each of the segment types is identified, a first condition value associated with a first condition is identified, a second condition value associated with a second condition is identified, and a driver score including respective component values based on the segment type values, the first condition value, and the second condition value is identified. The drivers are rated for one of the segments based on the respective multi-component driving scores.

Abstract: A method and system for pre-blocking ophthalmic lenses for processing including articulation edging is described. Lens blanks are blocked in this method without prior knowledge of lens prescription variables or frame size and shape dimensions. This blocking can be done at a remote mass production manufacturing facility. The pre-blocked lenses would then be inventoried at the lens manufacturing location. No de-blocking and re-blocking is required between the surfacing, for those lens blanks requiring surfacing, and edging processes so the lens blanks remain on their blocks from start to finish. If surfacing is required, both surfacing and edging are performed on the same machine with no interruptions between the two processes. Machine readable indicia on the Lens-Block Assemblies for Lens Blank species identification is described. Pre-blocking of finished uncut lenses for edging using articulation edging is also described.

Abstract: A method of manufacturing ophthalmic lenses comprises the steps of: a) mounting lens blanks on lens blocks at a blocking location; b) transporting the blocked lens blanks to at least one manufacturing site that is remote from the blocking location; and c) selectively machining ophthalmic lens from the blocked lens blanks at the manufacturing site on a machining platform, wherein the selective machining of ophthalmic lens includes back surface generation of the lens blanks and edging of the lens blanks at the manufacturing site on a single manufacturing platform.

Abstract: A dual ophthalmic lens machining platform comprises a blocked lens mounting structure constructed to simultaneously receive a first and a second blocked lens blank, and configured to rotationally and linearly move each lens blank, wherein the first and second lens blank have at least one common axis of movement on the mounting structure; and at least one machine tool adapted to machine each lens blank. A method of manufacturing ophthalmic lens comprises the steps of mounting at least a first and a second blocked lens blank on the machining platform; and simultaneously performing at least one machining process on the two blocked lens blanks on the machining platform. The dual ophthalmic lens machining platform is configured to simultaneously receive and machine a left and a right blocked lens blank for forming a left and a right lens of a pair of eyeglasses.

Abstract: A method and system for the manufacture of ophthalmic lenses comprising a computer (102) and a CNC machining platform (104) in operative connection with the computer. The CNC machining platform includes a mounting stage (110), a block (106) in releasable connection with the mounting stage, and a machining tool (112). When an unfinished lens blank (108) is properly mounted on the block, the computer is operative to direct the CNC machining platform to perform both back surface generation and patternless edging of the lens blank in one machining cycle. The computer is further operative to direct the CNC machining platform to machine a lap tool for each lens and machine a block for receiving each lens. The block is machined by the platform to include scribe lines for facilitating proper alignment of lens blank.

Abstract: A system for generating, editing, executing, monitoring and debugging an application program for controlling an industrial automation mechanism comprising components of logic, motion and/or process control. The programming and operating environments contain a single Man Machine Interface (MMI) with close and intuitive linkages between sequential programs and continuous programs that aid in the programming, operation and troubleshooting of application programs.

Abstract: An autotuning procedure for a PID-type controller employs a low frequency sine wave as an exciting input and models the controlled system as a second order linear system. The system is tuned to a desired damping ratio by following an overdamped trajectory, in closed loop gain and phase lag space, to the target closed loop gain and phase lag values on a locus of a desired damping ratio as based on that modeling system.

Abstract: A method for control of servomotors includes limiting velocity feedforward as a second input to a velocity control loop in response to a velocity command, which is a first input, reaching a predetermined limit. Gain parameters for proportional and integral portions of a velocity-torque control loop and for the proportional and integral portions of the velocity feedforward loop may be adjusted independently to obtain varying control responses from the control system. The method is carried out in a microcomputer-based control module for an industrial controller.
