1 band saw band within Friemann’s disclosed time frame appears to be orders of
2 magnitude more than the Andreasson capacitor can store.
3 Secondly, we find no suggestion or motivation for placing the capacitor of
4 Andreasson into the safety systems of Friemann or Yoneda. Both references
5 contemplate using electrical line power to stop their saw blades. In their
6 installations, this power is readily available, and it is unclear why one of ordinary
7 skill would use a giant capacitor to stop the saw blades.
8 Thirdly, Andreasson makes clear that the reason a capacitor is needed is that
9 the electromagnetic ignition system is the only source of electricity available.
10 With line power clearly available to Yoneda and Friemann, there appears to be
11 little incentive to use a capacitor as shown in Andreasson.
