(under subclass 399) Device including mechanism to start the movement of that portion of the assembly whose operation is controlled by the sensed object.
(1) Note. The difference between patents in this subclass (400) and patents in subclass 399 is that subclass 399 provides for structure wherein movement of the controlled member or assembly is permitted (e.g., by effecting release of an interlock), whereas this subclass (400) provides for structure wherein movement of the controlled member or assembly itself is started or accomplished as the direct result of the detection of the sensed object (i.e., element, pattern or other portion remote from the controlled member or assembly itself).
