    摘要: A personal rapid transit (PRT) system comprising a very economic triple rail topology for bi-directional urban personal transport. All the ramps are implemented on the one side of the tracks matching the narrow urban spaces. To achieve fast speed, stable direction changes, and a non-compromised passenger security, the ramps are implemented as parallel lines to the corresponding tracks, and the vehicles do not use any wheel steering. Instead, a landing wheel gear is implemented. The vehicle's center of mass is constantly kept in one plane with the guideways. In case of emergencies, a special “anti-fall down” security system holds the vehicle on the rails. The vehicles make turns using the highly compact Direction Change Connector. The PRT control system is implemented as three layer hierarchical system of fault-tolerant processor nodes, and utilizes two channel wireless communications between the layers.

    摘要: A system for inspecting specimens such as semiconductor wafers is provided. The system provides scanning of dual-sided specimens using a diffraction grating that widens and passes nth order (n>0) wave fronts to the specimen surface and a reflective surface for each channel of the light beam. Two channels and two reflective surfaces are preferably employed, and the wavefronts are combined using a second diffraction grating and passed to a camera system having a desired aspect ratio. The system preferably comprises a damping arrangement which filters unwanted acoustic and seismic vibration, including an optics arrangement which scans a first portion of the specimen and a translation or rotation arrangement for translating or rotating the specimen to a position where the optics arrangement can scan the remaining portion(s) of the specimen. The system further includes-means for stitching scans together, providing for smaller and less expensive optical elements.
