Abstract: A clutch includes a clutch fluid chamber with a movable clutch piston configured to selectively engage a clutch pack to connect an input drive portion and an output portion. A brake reaction plate is configured for selective frictional braking of the output portion. A brake fluid chamber contains a brake piston configured to selectively move the brake reaction plate from a disabled position to an enabled position. In a first state, the clutch pack is disengaged and the brake reaction plate is in the disabled position. In a second state, the clutch pack is engaged and the brake reaction plate is in the enabled position, without frictional braking of the output portion of the clutch being applied. In a third state, the clutch pack is disengaged and the brake reaction plate is in the enabled position such that frictional braking of the output portion is applied.

Abstract: Methods and related systems for indexing the contents of documents for comparison with the contents of other documents to identify matching content. A method for comparing the contents of a query document to the content on the World Wide Web is set forth. The contents of a query document are indexed and compared to content from the World Wide Web which is continuously retrieved and indexed. The method for indexing may comprise selecting substrings from the document, hashing the substrings to generate a plurality of hash values having a known range of values, selecting certain hash values to save from the generated hash values, and sorting the saved hash values. Methods for selecting certain hash values to save are set forth.
