Abstract: A probe having a probe tip, especially for use in an atomic force microscope, formed by micromachining techniques in a silicon wafer. The tip is photolithographically defined in a layer, preferably of silicon nitride deposited on the silicon wafer, and has a width and thickness of usually less than 250 nm. Thereby, the probe tip can be formed to have a generally square cross section in which one lateral dimension is determined by the layer thickness, and the other lateral dimension by the photolithography or by a subsequent step of focused ion beam milling. The portion of the silicon wafer underlying the area probe tip is etched away, preferably before the probe tip is etched, but another portion of the silicon is left to serve as a support at the base of the probe tip. A hinge may be formed in the silicon wafer, and the probe tip together with a robust shank can be made to rotate to a direction perpendicular to the wafer surface.

Abstract: A computer animation production system (2) for processing digital image data is disclosed. The computer animation production system (2) contains at least one information processing device (44-76) for enabling at least one user to develop, utilize and enhance digital image data. The information processing device (44-76) is associated with a first (4) and a second (6, 8, 10, 12 and 14) global area network (4). The first global area network (4) is for communicating digital control information to at least one information processing device. The digital control information includes image database information. The second global area network (6, 8, 10, 12 and 14) is for communicating the digital image data to the at least one information processing device (44-76). The digital image data includes pixel characteristic information for image reproduction on the information processing device.

Abstract: The invention relates to a heel and sole assembly for an adjustable arch shoe. The assembly comprises a fixed nondeformable support element forming a heel portion and a sole portion, a pivoting element which covers a rear portion of the sole and heel portions and which is articulated upon the sole through an axis which is perpendicular to the length of the shoe so as to pivot between a lowered position and one or more elevated positions, a locking element to lock the pivoting element in any one of its positions and a prestressed spring arranged between the fixed support element and the pivoting element to force the latter upwardly to a desired elevated position. Such an assembly makes it possible to instantly change the heel height of the shoe without removal of the shoe from the wearer's foot.

Abstract: A static random access memory which generates a memory status signal for improved performance. The same signal in a random access memory which enables data to go to the output is taken to form the leading edge of a memory status signal, indicating that output data is available. The trailing edge of the pulse, indicating a memory readiness condition, is formed upon completion of memory preset. The memory status signal tracks variations in performance of the data storage cells due to voltage, temperature and other processing variables, thus permitting access of data when data is actually available for reading, rather than on worst case considerations.
