Title: Automated apparatus and method for preparing contact lenses for inspection and packaging
Inventor: GUNDERSEN BORGE PETER
IPC: B65B57/00
Filed: 1995-06-08
Abstract: An apparatus is provided for removing and transporting articles, such as contact lens sections from a manufacturing line to inspection and packaging stations. The lenses are deposited in a transparent plastic primary package which carries the lenses through the inspection station and becomes part of the primary package when a cover is sealed thereto. The invention includes various assemblies, including lens transfer assemblies, deionized water filling and removal assemblies, a water degassing assembly, a lens inspection assembly, and a lens package sealing assembly. The lenses are removed from pallets at a post hydration station, transported and spatially redistributed, and deposited in the primary packages disposed on a second set of pallets. The packages on the second set of pallets are filled with degassed deionized water. The contact lenses and packages are then transported to an inspection station. After inspection, the lenses and packages are transported to a water removal assembly, and then to another transfer assembly. This transfer assembly separates those lenses which passed inspection from those which did not, and places those that did in a consolidating assembly. The lenses and packages are then filled with saline solution and a foil label is then sealed thereto to form the primary package.

Title: The copy protection of optical discs
Inventor: BASILE CARMEN LAURA
IPC: G11B20/00
Filed: 2005-04-27
Abstract: Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors. However, very few SDSV sequences of data symbols can be found in multimodal codes such as Eight-to-Sixteen Modulation (ESM) utilised in DVDs. It is required to select data symbols, for encoding using a multimodal code, which are capable of forcing an encoder to produce at least one subversive sequence of code words. A possible code word for a data symbol is selected if the code word has a large absolute value of DSV and there are no alternative code words, or all alternative code words are equivalent, or all alternatives except one are ruled out by RLL rules.

Abstract: Approaches are used for efficiently and effectively managing the dynamic allocation of resources of multi-node database systems between services provided by the multi-node database server. A service is a category of work that is hosted on the database server. The approaches manage allocation of resources at different levels. For services that use a particular database, the performance realized by the services is monitored. Resources assigned to the database are allocated between these services to ensure performance goals for each are met. Resources assigned to a cluster of nodes are allocated between the databases to ensure that performance goals for all the services that use the databases are met. Resources assigned to a farm of clusters are assigned amongst clusters based on service level agreements and back-end policies. The approach uses a hierarchy of directors to manage resources at the different levels.

Title: Method and apparatus for assessing a material
Inventor: HEYMAN JOSEPH S
IPC: G01N29/02
Filed: 2004-06-04
Abstract: An acoustic energy-based, non-contact or contact testing approach provides low cost, highly accurate, and reliable information to (a) identify flaws and anomalies and (b) assess the integrity of a particular material. This approach is not hindered by surface conditions or impediments, and indeed, looks beneath the surface of the material by propagating an acoustic wave through the material using two differential transducers. A dynamic differential measurement is made of the material under a load condition and an unloaded condition that allows identification and assessment of various characteristics of the material. Multiple "windows" of information may be generated that permit (a) direct detection of flaws, defects, and anomalies using a scattering technique, (b) detection of crack closure and opening used to assess the stability of the material, (c) determination of strain on the material which relates to its performance, and (d) determination of defect dynamics linked to the defect size and stability.
