Abstract:
1. A sensor mounting system for enabling image stabilization, comprising: a circuit carrier comprising a generally planar sensor mounting portion; an electronic array light sensor mounted on the circuit carrier sensor mounting portion; at least one linear motor that translates the circuit carrier sensor mounting portion in a direction generally parallel to the plane of the circuit carrier sensor mounting portion, wherein the at least one linear motor comprises a gap between a stator and a moving member of the at least one linear motor so that motion along X and Y axes is essentially free of static friction; and at least two flexible service loops that carry signals between circuitry on the circuit carrier sensor mounting portion and other circuitry, the other circuitry being stationary in relation to the stator of the motor, wherein the gap is substantially filled with a ferrofluid, the ferrofluid forming a fluid bearing that facilitates both the translation of the circuit carrier sensor mounting portion in the generally parallel direction and resisting motion of the circuit carrier sensor mounting portion in a direction generally perpendicular to the plane of the circuit carrier sensor mounting portion.
