    摘要： A piezoelectric motor comprising: a piezoelectric vibrator (50) having a surface comprising a localized non-planar shaped first surface region thereon which first surface region has a shape different from the shape of the surface on which it is located; and a friction nub (52) formed with a second surface region that is substantially a negative relief of the first surface region, which first and second regions are bonded together. Preferably the friction nub (52) is detachably mounted to the vibrator (50) via a boss (54) waving a protuberance (56) of conical shape. Alternatively the friction nub (52) has a protuberance (76) which is form-fitted to a recess (72) in the vibrator (50) or boss (70), respectively. First and second surface regions can also be threading surfaces.

    摘要： The disclosed piezoelectric motor (11) comprises two actuator assemblies and a frame (12). The first actuator assembly comprises a first piezoelectric actuator (10a) and two rollers (32a, 34a), each of the rollers pressed between the first piezoelectric actuator and a first frame side, and the second actuator assembly comprises a second piezoelectric actuator (10b) and two rollers (32b, 34b), each of the rollers pressed between the second piezoelectric actuator and a second frame side. The motor further comprises at least one pre-loaded spring (36, 38) provided between the first actuator assembly and the second actuator assembly, pushing the first actuator assembly against the first frame side and the second actuator assembly against the second frame side.

    摘要： A camera having an optic axis and comprising a foldaway transport system for a zoom lens: a zoom lens having a lens optic axis; a platform to which the zoom lens is mounted; a guide track to which the platform is mounted and along which the platform is moveable by means of a motor for performing zoom functions; wherein the guide track is rotatable about an axis perpendiculare to the camera optic axis between a first unfolded active position in which the optic axis of the zoom lens substantially coincides with the camera optic axis and a second folded away passive position in which the 200m lens optic axis does not coincide with the camera optic axis.

    摘要： A camera module has a plurality of lenses aligned along an optic axis that receive and transmit light from a scene being imaged by the camera module. At least one lens is mounted on a platform which is movable along the optic axis and is moved by action of a piezoelectric motor. Optionally, at least one lens is mounted on a second platform which is movable along the optic axis. The second platform may be driven by a second piezoelectric motor or moved by action of the first platform.

    摘要： An optical position monitor for determining the position of a latch needle (104) in a knitting machine is provided that comprises: at least one fiducial (102) at a known fixed location on the body of the latch needle; a fiducial imager that produces at least one optical image (262) of the at least one fiducial on at least one light sensitive surface (260) wherein the at least one optical image changes with changes in position of said at least one fiducial; and a controller that receives at least one signal responsive to the changes in the at least one image and uses the at least one signal to determine the position of the at least one fiducial (102) and thereby of the latch needle (104).
