摘要： In general, optical communication systems and methods may generate higher-level nmQAM from nQAM signals using one or more delay line interferometers (DLIs) arranged in various configurations. The nQAM signals may be generated by a lower-level modulator, such as a BPSK modulator, QPSK modulator or lower-level QAM modulator, with binary driving signals. Different parameters of the DLIs, such as free spectral range (FSR), phase shift, and amplitude imbalance, may be selected to accomplish the desired higher-level nmQAM depending upon the nQAM signal.

摘要： The present invention relates to a design and microfabrication method for microgrippers that are capable of grasping micro and nano objects of a large range of sizes and two-axis force sensing capabilities. Gripping motion is produced by one or more electrothermal actuators. Integrated force sensors along x and y directions enable the measurement of gripping forces as well as the forces applied at the end of microgripper arms along the normal direction, both with a resolution down to nanoNewton. The microfabrication method enables monolithic integration of the actuators and the force sensors.

摘要： Methods and structure for switching heads on a multiple recording surface disk drive that uses bi-directional radial writing toward a zipper zone at a middle diameter. When switching from a first head to a second head, features and aspects hereof assure that the second head will not be positioned in the zipper zone of the corresponding second surface and hence will not lose track following servo synchronization and control. In one aspect, added buffer or guard tracks having valid servo information but no data are added on either side of the zipper zone to assure that under the worst-case misalignment of surfaces the second head will not be positioned in its corresponding zipper zone when switching from the first head.

摘要： A piezoelectric element comprises a first laminated structure body and a second laminated structure body. Side surfaces of the first and the second laminated structure bodies that are parallel to a laminating direction both have at least a portion etched to form a recess so that a step distance is formed between sides of the two adjacent electrode layers that are parallel to the laminating direction. The design of the step distance of the present invention increases insulation resistance between the two adjacent electrode layers on the opposite surfaces of the piezoelectric layer, lowers reject rate, and reduce manufacture cost. The first and the second laminated structure bodies are symmetrically laminated and bonded together, thus optimizing force balancing performance. The recess of the first and second laminated structure body may be filled with insulation resin, which also increases insulation resistance between the two adjacent electrode layers of the piezoelectric layer. The present invention also discloses a method of manufacturing a PZT element, a HGA with the PZT element and a disk drive unit having such HGA.
