DEFINITION

Classification: 65/377

With measuring, controlling, sensing, programming, timing, indicating, or testing:

(under subclass 376) Processes including measuring, controlling, programming, sensing, timing, indicating, or testing fibers, filaments, or preforms during any stage of their manufacture or treatment.

(1) Note. Patents directed to measuring, controlling, sensing, inspecting, indicating, or testing the contour, shape, coating, internal molecular arrangement, or specific composition of fibers, filaments, or preforms are included in this subclass.

(2) Note. Process controls responsive to sensed conditions including program, cyclic, time, or automatic controls are proper for this and indented subclasses.

(3) Note. Equivalent terms include examining, diagnosing, analyzing, eval-uating, and monitoring.
