Abstract: The present invention comprises nucleoside derivatives for use in the treatment or prophylaxis of hepatitis C virus infections. In particular, the present invention discloses the novel use of known 2′-deoxy-2′-fluoro nucleoside derivatives as inhibitors of hepatitis C virus (HCV) RNA replication and pharmaceutical compositions of such compounds. The compounds of this invention have potential use as therapeutic agents for the treatment of HCV infections.

Abstract: A communication system includes an echo canceller and double-talk detector. The echo canceller includes an adaptive finite impulse response filter that generates an adaptive filter weight vector. The double talk detector computes a squared norm of the filter weight vector and detects an increase of the squared norm in order to detect double-talk status. Upon detection of double-talk status, operation of the echo canceller is suspended.

Abstract: In accordance with the objectives of the invention a new method is provided for repairing photolithographic exposure masks. The invention uses an etch function of a conventional mask repair tool. The invention addresses defects that occur in a pattern of opaque material (such as chrome) created over the surface of an exposure mask whereby an (undesired) opening exists in the opaque material. The invention uses a focused E-beam exposure of the surface of the exposure mask to purposely “damage” this surface over the area where the opaque material is required to be present. Repair accuracy is in this manner easy to control, the conventional problem of peeling of the opaque or light sensitive material is eliminated.

The use of these derivatives for the treatment of HCV infection is claimed as are the novel nucleoside derivatives disclosed herein.

Abstract: A user is prompted to select at least one search parameter for a search of contest data for a plurality of contest events and user wager data, the user wager data identifying a plurality of wagers placed by the user on contest events from the plurality of contest events. At least one search parameter selected by the user is received, and wagers placed by the user that satisfy the at least one search parameter selected by the user are identified. A return on the wagers placed by the user that satisfy the at least one search parameter selected by the user is calculated, and wagering return data corresponding to the return are displayed to the user.

Abstract: A method and apparatus for enhancing a speech signal contaminated by additive noise through Kalman filtering. The speech is decomposed into subband speech signals by a multichannel analysis filter bank including bandpass filters and decimation filters. Each subband speech signal is converted into a sequence of voice frames. A plurality of low-order Kalman filters are respectively applied to filter each of the subband speech signals. The autoregression (AR) parameters which are required for each Kalman filter are estimated frame-by-frame by using a correlation subtraction method to estimate the autocorrelation function and solving the corresponding Yule-Walker equations for each of the subband speech signals, respectively. The filtered subband speech signals are then combined or synthesized by a multichannel synthesis filter bank including interpolation filters and bandpass filters, and the outputs of the multichannel synthesis filter bank are summed in an adder to produce the enhanced fullband speech signal.

Abstract: A telescopic wrench extensioner includes a tubular member with a closed end portion that has a polygonal axial recess which is adapted to engage a socket wrench, and a shaft member having a first end slidably extending into the tubular member and a second end extending out of the tubular member and being provided with an axial socket operating portion that is polygonal in cross section and that is adapted to engage a wrench socket. The shaft member can be maintained at a selected position relative to the tubular member.
