ULTRASONIC LOW FRICTION COMPASS

摘要

The direction determination device includes a magnetized pointer having an indentation surface; a stationary housing; an elongated pivot located centrally near a top of the stationary housing and having a tapered end and a central axis, the tapered end engaging a indentation surface; a motor mechanism mounted within the housing and attached to the elongated pivot; and a power source selectively coupled to the motor mechanism to cause movement of the pivot relative to the housing in such as manner so as to create a near frictionless contact between the pivot tapered end and the indentation surface of the magnetized pointer.

1. A low friction bearing apparatus comprising:
(a) a first structure; (b) a second structure bearing against the first structure and movable relative thereto; and (c) a vibration mechanism engaged with the first structure to vibrate the first structure to thereby cause the second structure to be periodically disengaged from the first structure to thereby reduce friction between the second structure and the first structure.
