Filed: 1993-01-19
Abstract: A vibration isolator (10) has four fluid-filled variable volume toad-bearing chambers (32a-d), with two arranged on one side of a core (20) and the ether two on the other side. The core (20) and chambers (32a-d) are contained within a frame (12), with the chambers (32a-d) extending between the core (20) and the frame (12), so that vibrating the core (20) axially compresses or ex-tends the chambers (32a-d). Diagonally opposite pairs (32a-d, 32b-c) of chambers (32a-d) are each connected with a separate fluid track (70, 72), and the two fluid tracks (70, 72) may be tuned to have different resonant frequencies or the same resonant fre-quency. The chambers (32a-d) are defined by elastomeric bodies (24a-d) which may be reinforced using a tubular shaped reinfor-cing element (26a-d) adjacent to the chamber (32a-d), to help contain the pressures within the chamber (32a-d) without materially increasing the compression strength of the elastormeric bodies (24a-d). A  fluid expansion chamber (50) communicates with the fluid envelope of the chambers (32a-d) and tracks (70, 72) through porous flow restriction elements (64) which allow flow to or from the expansion chamber (50) in response to temperature changes of the fluid but snub significant flow to or from the expand-sion chamber (50) which may otherwise be caused by subjecting the isolator (10) to vibrations.

Inventor: HUANG ZHENG
IPC: H04N7/26
Filed: 1995-01-18
Abstract: Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks. Each block contains N symbols wherein M of the symbols comprise information to be transmitted and the remaining N-M of the symbols comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks in the data stream are divided into a succession of frames, each comprising F of the coded blocks. A frame overhead symbol is added for each of the frames, to provide data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second information rate M'/N', where M/N = (M' + b)/(N' + b) and b is an integer chosen to provide the second information rate at a desired value. N is less than 2n + 1, where n is the number of bits in each of the symbols. The number of coded blocks F in each frame is determined from the relationship F = M'P/(N-M)b.      P is the smallest value integer that will render F an integer, and is also the number of overhead symbols added per frame. A plurality of X of the frames are formed into a superframe containing FX coded blocks and PX frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function.

Title: Language identification with phonological and lexical models
Inventor: HIERONYMUS JAMES LEE
IPC: G10L15/197
Filed: 1995-10-10
Abstract: A method and apparatus for identifying a speech signal as representing speech in a given candidate language. First, the described illustrative embodiment performs a language-specific phoneme recognition on the speech signal for the given candidate language. Next, a corresponding phonemotactic (i.e., phoneme transition probability) model for the given language is applied to produce one or more corresponding phoneme sequences and associated likelihood scores (e.g, probabilities). Then, a corresponding lexical model for the given language is applied to the phoneme sequences and their associated likelihood scores. In this manner, the lexical characteristics of the given language are taken into account in order to identify the most likely phoneme sequence (assuming that the given candidate language is, in fact, the language which was spoken) and its associated likelihood. This associated likelihood is used to provide a resultant likelihood score for the given candidate language. Finally, the speech signal isidentified as representing speech in the given language based on the resultant likelihood score so obtained. In particular, the speech signal is analyzed in accordance with the above with respect to each of a plurality of candidate languages, and is identified as representing speech in the candidate language which produces the highest likelihood score.
