In one embodiment, a specialty wrench has a handle that is movable from a first position where the wrench acts as a conventional pipe or Stillson wrench and a second position where the handle is inclined, perhaps as much as 90\xb0. A data line is positioned on the data line region of the lower substrate to overlap the light blocking layer with a gate insulating layer interposed therebetween. Each insert tower contains multiple insert hoppers aligned vertically within the tower. mx=2\u2062Lx\u03bbx+\u03a6x2\u2062\u03c0. Specifically, the paper currency counter of the present invention incorporates electronic circuitry which automatically stops the mechanical motors in the event a foreign object is accidentally ingested by the counter.
