    摘要： A thermal actuator comprises a plurality of substantially straight and parallel beams arranged to form a beam array. The midpoint of each beam is attached or coupled to an orthogonal coupling beam. Each array beam has a beam heating parameter with a corresponding beam heating parameter value. The beam heating parameter values vary across the beam array based on a predetermined pattern. As the beams are heated by an included heating means, the distribution of beam temperatures in the beam array becomes asymmetric, thus causing the beam array to buckle. The buckling of the beams in the beam array, in turn, causes the attached coupling beam to move in a predetermined direction. The coupling beam motion, in turn, operates an included optical waveguide switch. The beams in the beam array are heated by any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

    摘要： An improved cantilever beam optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a cantilever beam platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alterative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

    摘要： A substantially straight beam in an unbuckled state is compressed to cause the beam to buckle using an adjustable compressor. The adjustable compressor applies force to one or both ends of the beam and limits compression on the beam to allow the beam to move between a first buckled state and a second buckled state. The first buckled state and the second buckled state comprise substantially equal magnitude and opposite direction buckling movements from the unbuckled state.

    摘要： A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments with beam segment lengths. Each beam segment has a beam segment neutral axis, thus forming a corresponding plurality of beam segment neutral axes. The beam segment neutral axes are offset along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in the predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

    摘要： An electrostatic actuator includes a segmented flexible membrane associated with individually addressable electrodes, one for each membrane segment. The electrodes are provided beneath a corresponding one of the membrane segments to define a plurality of actuator chambers between each of the electrodes and the corresponding membrane segment. Control electronics independently provide a bias voltage to select ones or all of the electrodes to generate an electrostatic field between any bias electrode and the corresponding membrane segment to attract the corresponding membrane segment toward the respective electrode. Upon elimination of the bias voltage, the corresponding membrane segments are elastically restored to their previous position. This structure can be incorporated into a fluid drop ejector to achieve variable drop size by control of the number of segments actuated. Additionally, by control of the time and space domain of the segment firing, the pressure pulse created by the fluid drop ejector can be precisely controlled.
