摘要： A tracer is provided for tracing a lens mount of an eyeglass frame, a lens or a lens pattern. The tracer comprises an object engager and an actuator. The object engager is adapted to engage the lens mount, the lens or the lens pattern. The actuator is adapted to move the object engager into contact with and then along the lens mount, the lens or the lens pattern in such a way that during movement therealong, the object engager remains against the object being traced even when the shape thereof includes high wrap. Preferably, the tracer has a shift mechanism adapted to shift the object engager from alignment with the lens mount to alignment with a second lens mount of the eyeglass frame. The actuator preferably is further adapted to trace the second lens mount in substantially the same way as the first. The actuator further includes a rotator and a pivot mechanism. The rotator is adapted to rotate the object engager along the object being traced. The pivot mechanism facilitates movement of the object engager toward or away from the axis as the object engager is actuated along the object. The object engager can extend or retract along the pivot mechanism. A clamp for the tracer and an object engager also are provided.

摘要： A control system is provided for a pivotally actuated tracer which traces an object (e.g., a frame mount of an eyeglass frame, a lens, or a lens pattern) while the object is held in a more-vertical-than-horizontal orientation. The control system comprises a trace control element and a gravity compensation element. The trace control element applies control signals to the pivotally actuated tracer. In response, the object engager of the tracer is pivotally actuated against and along the object to be traced with a biasing force toward the object. The gravity compensation element is adapted to compensate for the effects of gravity on the object engager by causing a varying pivoting force to be exerted on the object engager. The pivoting force varies depending on the rotational orientation of the object engager to keep the biasing force substantially constant along the object. Also provided is a data acquisition system for the tracer. The data acquisition system comprises a position monitoring element and a conversion element. The position monitoring element detects pivot information and extension information during a tracing operation. The pivot information and extension information define polar coordinate information when combined with rotational information indicative of the rotational orientation of the object engager. The conversion element provides cylindrical coordinate information based on the polar coordinate information. Methods which can be carried out by the system(s) or otherwise also are provided, for achieving similar results.
