Patent ID: 7743672

Claim:
A controller for providing operation in multiple axes, comprising: a load cell having an outer peripheral frame having a central axis with a central concentric area about said axis, said load cell having a plurality of pairs of a first beam section and a second beam section positioned between said central area and said outer peripheral frame, each beam section having an elongated rectangular cross-section, wherein the first beam section has wide top and bottom surfaces and narrower side surfaces, with said wide surface of said first beam section are positioned normal to the axis of said frame, and the second beam section extends from said first section, said second beam section having wide top and bottom surfaces and narrower side surfaces, with said wide surfaces of said second beam section are parallel to the axis of said frame; a plurality of strain gages, with at least one gage positioned on one wide side of said first beam section and at least one gage positioned on said wide side of said second beam section; a movable member coupled to said central area and operative to apply torsional or axial forces to said central member to cause said first beam sections and said associated gages to provide an output proportional to mainly said axial force and to cause said second beam sections and said associated gages to provide an output proportional to mainly said torsional force.
