    摘要： A lens driving apparatus includes: a fixed assembly, the fixed assembly including a base frame; a movable assembly, the movable assembly including a lens holder; a set of magnets surrounding the movable assembly; three sets of coils; and a spring system attached between the movable assembly and the fixed assembly and configured to support the movable assembly and form a suspension system to allow the movable assembly to move along a first, a second, and a third orthogonal axes. The lens holder is configured to hold a lens unit, the third axis is parallel to an optical axis of the lens unit, while the first and second axes are respectively perpendicular to the third axis.

    摘要： A method of sensing movement or proximity of objects by optical reflection is provided. The method includes the steps of transmitting a train of optical pulses towards a destination, sensing optical pulses reflected from the destination, and sensing and evaluating movement or proximity characteristics of objects at the destination with reference to variation in pulse width between transmitted and reflected optical pulses.

    摘要： An optical arrangement includes a position sensitive optical detector, a collimated optical source, and a processor configured to monitor the inclination of an object. The collimated optical source is configured to transmit a collimated beam towards the object. The position sensitive optical detector is configured to detect the specific location of incidence of an optical signal received from the object, and the processor is configured to generate information relating to the inclination of the object from processing optical signals received at the position sensitive optical detector.
