  • Flanged collet for die pick-up tool
    Patent number: 8226796
    Abstract: A collet is provided for picking up a die mounted on an adhesive surface. A flat platform at an end of the collet is configured to hold a planar surface of the die during pick-up of the die and a flange protruding from one side of the platform is operative to push against a side of the die which is substantially perpendicular to the planar surface of the die during a die pick-up process.
    Type: Grant

  • Sequence online analytical processing system
    Patent number: 8160996
    Abstract: A sequence online analytical processing (S-OLAP) system 50 for analysing an event database (41) storing events (12), the system (50) comprising: an S-OLAP engine (53) to compute an S-cuboid (49) for a query on the event database (41); a sequence query engine (54) to form part of the S-cuboid (49) by performing the steps of: selection, clustering, sequence formation and sequence grouping; a cuboid repository (52) to store computed S-cuboids (49) and to be searched by the S-OLAP engine (53) for an S-cuboid query to determine whether an S-cuboid has previously been computed; and a sequence cache (56) to cache constructed sequence groups.
