More specifically, the present invention relates to methods of designing gauge patterns that achieve complete coverage of parameter variations with minimum number of gauges and corresponding measurements in the calibration of a lithographic process utilized to image a target design having a plurality of features. According to some aspects, a method according to the invention includes transforming the space of model parametric space (based on CD sensitivity or Delta TCCs), then iteratively identifying the direction that is most orthogonal to existing gauges' CD sensitivities in this new space, and determining most sensitive line width/pitch combination with optimal assist feature placement which leads to most sensitive CD changes along that direction in model parametric space.09-15-2011

20080245945Modified tripod and "multi-pod" for cameras and other equipment - As one of the examples, one of the main features is that the setup is small enough that it can live with the camera full-time, and carried around by the user. The legs fold into a very compact size that fit within the footprint of the camera, used for any type camera, e.g. compact point-and-shoot camera, camera phone, or SLR camera. The tripod can then live unnoticed on the bottom of the camera, until a shot requiring a tripod is needed. Then, the legs can be deployed to act as a firm stand. Another one of the main features of this tripod is that all the legs do not share a common end-point or pivot-point. This allows the legs to form a very wide stable platform, even when they are short. In general, for N legs, some legs may have common end-points or pivot-points, but not for all N legs. (N is a positive integer, greater or equal to 3.) This invention can be applied to any camera (e.g. compact camera) and any measurement equipment that uses a conventional tripod or similar setup, such as the ones used by civil engineers or surveyors for the survey of the land and construction measurements or calibrations, or the ones used in optical measurements or laser experiments (e.g. for general level measurements and adjustments). Other variations are also discussed.10-09-2008

20110023050SYSTEM AND METHOD FOR TIME-AWARE RUN-TIME TO GUARANTEE TIME - A method and system for achieving time-awareness in the highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques.
