Title: Vibration and noise absorbing device for hydraulic systems
Inventor: KNAPP ALFONS
IPC: F16K47/02
Filed: 1994-05-27
Granted: 2005-04-05
Abstract: Device for absorbing vibrations and noise produced in a hydraulic system, of the type comprising at least one casing (15, 16, 26, 41) of a flexible material, which encloses an air pocket (17, 18, 27, 40) and is placed in contact with the water contained in the hydraulic system, said casing (15, 16, 26, 41) being located in a diverted space (19, 20, 29, 45, 59) communicating with the spaces through which the water flows, but wherein the water does not flow significantly through said space, so that the casing is not directly touched by the waterflow and is thus not subjected to its dynamic effects. The casing may have various shapes, particularly a substantially cylindrical shape (15, 16, 26), or it may be shaped as a capsule (41). The diverted space in which the casing is arranged may be connected to a hydraulic circuit through one of its ends or through holes or channels of a dividing unit. Since it is not directly biassed by the water-flow, the casing (15, 16, 26, 41) may in any case comprise very thin sections and provide a particularly efficient absorbing effect without being subjected to damage. The device may also be installed in apparatus with highly restricted space.

Patent CA-2155693-C (CA)
Inventor: FISHMAN DANIEL A
IPC: H04B10/08
Filed: 1995-08-09
Granted: 1999-12-14
Abstract: Monitoring of optical amplifiers is accomplished, in accordance with the invention, by an apparatus and method for detecting a power level of a tone modulated upon a signal input to the amplifier, detecting an output power level of the amplifier, and comparing the power level of the tone to the output power level of the amplifier to determine an indication of the performance of the amplifier. In illustrative embodiments of the invention, each of the individual channels within a multiplexed optical signal are modulated with a specific low-frequency tone. The modulating is performed at the transmission site of the optical signal, and the specific tone frequencies are chosen to be lower than the low-frequency cut-off of any other information encoded upon the optical signal. The channel power of each channel is determined after each stage of optical amplification in the network by measuring the power of its respective unique low-frequency tone using a low-cost monitor. The total optical output power of the optical amplifier is also measured by the monitor. The ratio between the tone power and the optical amplifier output power after the first stage of optical amplification in the network is compared to the tone power/output power ratio at each subsequent optical amplification stage. Changes between the first and subsequent tone power/output power ratios reflect changes in network performance. The changes in tone power/output power ratio are strongly correlated to actual changes in optical signal-to-noise ratio. Advantageously, such a monitor may be built-in to each optical amplifier in the network, and no complex calibration of any components in the network is needed. Since each optical amplifier has a dedicated monitor which determines the status of each channel, faults in the network may be readily and quickly located to a specific optical amplifier and a specific channel.

Abstract: An optical configuration for flow cytometers which allows the sample stream, which carries the cells to be measured, to be excited in two separate foci of different wavelengths. The excitation light is focussed on the sample stream by a lens (5) which has its optical axis (14) and object plane (7) coinciding with that of another lens (16) situated opposite to it and which is collecting fluorescence and light scattering from said cells and forms fluorescence images of said sample stream in different image planes (19, 20 and 34) which are separated by dichroic mirrors (18, 33). Said lens (16) contains a field stop (17) which stops direct excitation, so that only fluorescence and scattered light reach said image planes (19, 20, 34). Behind said image plane (19), which contains scattered light from said cells, is a telescope (21) which makes an image of said field stop (17) in a plane (23). In said plane (23) are two concentric mirrors (24, 25) which isolate light of small and large scattering angle, respectively, and direct this light onto separate light detectors (30, 32). By means of dichroic mirrors and band filters different spectral components of the fluorescence separated and directed onto separate light detectors (44, 45, 46, 47). Slits (35, 36, 37) in the image planes (19, 20, 34) eliminate background light from the part of said object plane (7) which does not contain said sample flow.

Title: Speaker verification method and apparatus using mixture decomposition discrimination
Inventor: GANDHI MALAN BHATKI
IPC: G10L17/00
Filed: 1996-04-02
Granted: 2001-01-02
Abstract: A new speaker verification method, termed Mixture Decomposition Discrimination, (MDD) and a new apparatus for using MDD are presented. MDD takes mixture component score information from a speaker independent recognizer and transmits this information while it is still decomposed as a mixture of component scores that indicate the response of the states of the HMM before this information is combined into a single speaker independent recognizer parameter. MDD can be veryeffective in improving the performance of existing verification methods based onspeaker dependent HMMs with cohort normalization because the errors of the two speaker verification methods are very uncorrelated statistically. Experimental results have shown that when MDD is incorporated into a system that also uses speaker dependent HMMs, the resulting hybrid system has its average equal error rate reduced by 46% compared to cohort normalized speaker independent HMM. MDD is used with a speaker dependent linear discriminator which has relatively low computational and storage requirements. Thus, the increased performance of a hybrid MDD/CNHMM system may be achieved with minimal increase in computational and data storage assets.

Title: Method and apparatus for the transmission of variable rate digital data
Inventor: ZEHAVI EPHRAIM
IPC: H04B1/707
Filed: 1994-10-26
Granted: 2003-10-14
Abstract: A communication system for transmitting variable rate data is disclosed wherein redundancy is added to the variable rate data to provide repetition symbols. The repetition symbol data is transmitted with symbol energy scaled in accordance to the rate of the variable rate data when the variable rate data is greater than or equal to a nominal data rate. When the variable rate data is less than the nominal data rate, the symbol data is transmitted at nominal symbol energy and redundancy is removed by transmission gating of a proportion of the transmission symbol data determined in accordance with the rate of the variable rate data. Furthermore, a receiver for receiving the variable rate data is disclosed which uses the redundancy in the transmitted data symbol stream to make a corrected estimate of the transmitted symbol data.
