    摘要: An improved approach is described for implementing transformations of data records in high concurrency environments. Each transformation is performed in parallel at the source when the data record is first generated. According to one approach for data integrity validation, record generators compute an integrity checksum for a newly generated record before copying into a data unit in shared memory. Subsequent generators may aggregate integrity checksums for data records into checksums for data units incrementally. This approach achieves end-to-end protection of data records against corruption using an efficient method of maintaining verifiable data integrity. In another approach, compression and encryption data transformations may be performed by themselves, or in combination with an integrity checksum transformation.

    摘要: A wafer positioning device providing superior precision in a very thin configuration. Piezoelectric (vs. electrostrictive) solid state actuators provide precise positioning. To provide a thin configuration, the actuators are positioned horizontally. To move the wafer vertically, and to magnify the stroke of the actuators, there are provided displacement transformers. The positioning device provides positioning along four degrees of motion. The device can be mounted onto an x-y table to provide positioning along all six degrees of motion.
