Title: Minicapsulorhexis valve
Inventor: CHAPON PASCAL
IPC: A61F2/16
Filed: 2000-02-22
Abstract: A mini capsulorhexis valve device is composed of a curved, flexible discoid flap-valve member shaped to align with an ocular lens capsular bag inner surface, and a curved, flexible retainer member shaped to align with an ocular lens capsular bag outer surface, the curved, flexible retainer member being attached at a fastening point to the curved, flexible discoid flap-valve member. Attachement of the curved, flexible discoid flap-valve member to the curved, flexible retainer member may be via bonding with a silastic adhesive. In a method of accessing an ocular lens, the mini capsulorhexis valve device establishes a portal controlling access to an ocular lens. The method may include inserting a cannula through the mini capsulorhexis valve device to permit removal of a crystalline lens matrix and replacement thereof with a capsular filling material. The method may also include injecting a cytotoxic agent into a lens capsule, during which leakage of the injected cytotoxic agent is prevented by the mini capsulorhexis valve device.  The method may further include adjusting the refractive power of capsular filling material by adding or removing capsular filling material from the lens capsule during lens replacement surgery or post-surgically.

Inventor: FANTY MARK
IPC: G10L15/07
Filed: 2001-02-23
Abstract: A telephone-based interactive speech recognition system is retrained using variable weighting and incremental retraining. Variable weighting involves changing the relative influence of particular measurement data to be reflected in a statistical model. Statistical model data is determined based upon an initial set of measurement data determined from an initial set of speech utterances. When new statistical model data is to be generated to reflect new measurement data determined from new speech utterances, a weighting factor is applied to the new measurement data to generate weighted new measurement data.  The new statistical model data is then determined based upon the initial set of measurement data and the weighted new measurement data. Incremental retraining involves generating new statistical model data using prior statistical model data to reduce the amount of prior measurement data that must be maintained and processed. When prior statistical model data needs to be updated to reflect characteristics and attributes of new speech utterances, statistical model data is generated for the new speech utterances. Then the prior statistical model data and the statistical model data for the new measurement data are processed to generate the new statistical model data.

Abstract: A pressure loss in an oxidative gas passage of each of single cells is obtained by causing gas to flow through the oxidative gas passage and calculating a difference between gas pressures detected by first and second pressure gauges. This pressure loss is compared with predetermined ranks so as to carry out classification according to the ranks. The pressure loss in the oxidative gas passage has a predetermined permissible range that is divided into two or more small ranges, which are referred to as a first rank, a second rank, ...., and an n-th rank respectively. The single cell that is to be measured at the moment is classified into a certain one of the ranks depending on which one of the first to n-th ranks corresponds to the pressure loss in the oxidative gas passage. Classification is similarly carried out as to a pressure loss in a fuel gas passage as well. Those of the single cells which are equivalent in rank are gathered up and combined to fabricate a fuel cell.
