Abstract: A system for providing fuel to an engine fuel delivery system and to an exhaust aftertreatment system associated with an engine. The system includes a fuel source, a pump being operable in a first state to pump fuel from the fuel source to the engine fuel delivery system, and the pump being operable in a second state to pump fuel from the fuel source to the exhaust aftertreatment system, wherein the first state corresponds to a first rotational direction of the pump and the second state corresponds to a second rotational direction of the pump.

Abstract: A liquid pump includes an electronically controlled throttle inlet valve to control pump output. With each reciprocation cycle, a plunger displaces a fixed volume of fluid. When less than this fixed volume is desired as the output from the pump, the electronically controlled throttle inlet valve throttles flow past a passive inlet check valve to reduce output. As a consequence, cavitation bubbles are generated during the intake stroke. Cavitation damage to surfaces that define the inlet port passage are avoided by a specifically shaped and sized cavitation flow adjuster extending from the valve member of the passive inlet check valve. By positioning the cavitation flow adjuster in the inlet port passage, a flow pattern is formed in a way to encourage cavitation bubble collapse away from surfaces that could result in unacceptable cavitation damage to the pump.

Abstract: Speech recognition such as command and control speech recognition generally use a context free grammar to constrain the decoding process. Word or subword background model are constructed to repopulate dynamic hypothesis space, especially when word spareness is at issue. The background models can be later used in speech recognition. During speech recognition, background and conventional context free grammar decoding are used to measure confidence. The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

Abstract: Reliable transcription error-checking algorithm that uses a word confidence score and a word duration probability to detect transcription errors for improved results through the automatic detection of transcription errors in a corpus. The transcription error-checking algorithm is combined model training so as to use a current model to detect transcription errors, remove utterances which contain incorrect transcription (or manually fix the found errors), and retrain the model. This process can be repeated for several iterations to obtain an improved speech recognition model. The speech model is employed to achieve speech-transcription alignment to obtain a word boundary. Speech recognizer is then utilized to generate a word-lattice. Using the word boundary and word lattice, error detection is computed using a word confidence score and a word duration probability.

Abstract: A reliable full covariance matrix estimation algorithm for pattern unit's state output distribution in pattern recognition system is discussed. An intermediate hierarchical tree structure is built to relate models for product units. Full covariance matrices of pattern unit's state output distribution are estimated based on all the related nodes in the tree.

Abstract: The present invention provides a method and apparatus for ciphertext indexing and searching. Indices of multiple levels are created for the encrypted files. Each item in the primary index includes a primary index item identifier and the ciphertext of the primary indexing information of the related file. The primary indexing information each includes an identifier(s) of the related secondary index item identifier(s) and the corresponding decryption information. Each item in the secondary index includes a secondary index item identifier and the ciphertext of the secondary indexing information. Information necessary for obtaining a file is included in the corresponding secondary indexing information. With the decryption information of the secondary indexing information in the decrypted primary indexing information, the ciphertext of the related secondary indexing information is decrypted so as to obtain information such as the decryption key of the file.

Abstract: The present invention provides a method and apparatus for generating index as well as a search method and a search apparatus. Index entry comprises at least a search item identifier corresponding to a search item, one or a plurality of index items generated from one or plural pieces of search information, and an accumulator for the search information. The accumulator is generated by accumulating the search information, or accumulating ciphertext of information containing the search information, or accumulating data mapped from information containing the search information. At the time of searching, the index items and the accumulator are provided to a searcher. The searcher extracts search information from the index items and checks whether the extracted search information is complete by using the accumulator. In one embodiment, the accumulator is incorporated in an encrypted inverted index.

Abstract: The present invention provides a method, apparatus and system for fast searchable encryption. The data owner encrypts files and stores the ciphertext to the server. The data owner generates an encrypted index according to each keyword of the files, and stores the encrypted index to the server. The index is composed of keyword item sets each being identified by a keyword item set locator and containing at least one or more file locators of the files associated with the corresponding keyword. Each file locator contains ciphertext of information for retrieval of an encrypted file and only with the correct file locator decryption key can the ciphertext be decrypted. Data owner issues a keyword item set locator as well as file locator decryption key to a searcher to enable the searcher to search on the encrypted index and retrieve files related to a certain keyword.
