Patent ID: 7281490

Claim:
A gauge for indicating a measured variable, said gauge including: a motion detection device including a drive magnet, said drive magnet adapted to be movable in response to changes in the variable; a pointer rotation device adapted to rotate about a first axis, said pointer rotation device including a pivot member, a power magnet coupled to said pivot member, a first director member located adjacent said power magnet, said first director member including a generally helical flange, and a second director member, said second director member including a generally helical flange, said power magnet being located between said first director member and said second director member, said flanges of said first director member and said second director member being generally equally spaced from one another; said power magnet forming a magnetic field adapted to magnetically couple said pointer rotation device to said drive magnet; and a pointer coupled to said pointer rotation device; whereby movement of said drive magnet of said motion detection device pivots said pointer rotation device and said pointer about said first axis.
