  • Patent number: 11959993
    Abstract: A method and system for enabling the determination of a position of a receiver within a space includes transmitting a beacon signal from each of a plurality of beacon devices located at different locations within the space. The beacon signal transmitted from each beacon device has a unique information component and may have a unique frequency pattern of multiple frequencies. Each beacon signal can be distinguishable from the beacon signals transmitted from any other of the beacon devices based on the combination of its unique information component and its unique frequency pattern. The beacon signals are received at a receiver. At the receiver, for each beacon signal of a working subset, time-delay information of the received beacon signal is determined and multilateration is applied to determine the position of the receiver based on the location of each beacon device of the working subset.

  • Publication number: 20130103336
    Abstract: A technique for identifying a defect in an object produced by a controllable process is disclosed. A first type of data generated as a result of production of the object by the controllable process is obtained. A second type of data generated as a result of production of the object by the controllable process is obtained. The first type of data and the second type of data are jointly analyzed. A defect is identified in the object based on the joint analysis of the first type of data and the second type of data.

A second type of data generated as a result of production of the object by the controllable process is obtained. The first type of data and the second type of data are jointly analyzed. A defect is identified in the object based on the joint analysis of the first type of data and the second type of data. By way of example, the controllable process comprises a semiconductor manufacturing process such as a silicon wafer manufacturing process and the object produced by the semiconductor manufacturing process comprises a processed wafer. The first type of data comprises tool trace data and the second type of data comprises wafer image data. The tool trace data is generated by a photolithographic tool.

  • Publication number: 20120194361
    Abstract: A method for encoding an input file into an output file that is compressed so that the number of bits required to represent the output file is less than the number of bits of the input file. The encoding method includes the parsing of the input file into a series of data items, the data items having an order and collectively corresponding to the input file. The encoding method compares the series of data items against a static dictionary having at least mappings between terminal sequence pointers and representations of data items.

  • Patent number: 7905667
    Abstract: A walking staff apparatus having a tripod assembly that is releasably fastened to a main shaft. The tripod assembly may be released from the shaft to achieve a compact arrangement for transport or storage. The shaft may also be telescoping to achieve a compact size. The release joint may include a mechanism for centering the shaft and tripod assembly. A magnetic-based mechanism for releasable attachment of an article may be coupled to the shaft. The magnetic-based attachment mechanism may include an anti-rotation device to achieve secure positioning of an article releasable attached to the shaft.
