DEFINITION

Classification: 414/275

With means to detect obstruction and alter movement of charging or discharging means:

(under subclass 273) Apparatus with means for determining whether the path of the charge will cause undesired contact with an object (e.g., because of the path being blocked by a misaligned charge, because of improper clearance with a load-underlying member, etc.), and for altering the motion of the moving means to avoid, or to minimize the effect of, such contact.
