DEFINITION

Classification: 144/392

Sensing work or product (e.g., X-ray):

(under subclass 391) Subject matter including detecting a characteristic of the work* for, or the product* of, the machine.

(1) Note. Sensing a "Blank Holder"* or a work* holder is included herein.

(2) Note. A woodworking tool* is not considered to be a "detector"; therefore, detecting a tool* in direct engagement with the work is not considered to be detecting the "work or product" for placement in this subclass.
