| 20090074349 | FABRICATION OF FIBER OPTIC PROBES - A method of fabricating a sensor probe comprises: | 03-19-2009 |
| 20100007892 | OPTICAL SENSING OF MEASURANDS - A dome-shaped chemical sensing probe comprises an optical fiber or may be mounted on an optical fiber. The probe has a chemically sensitive measuring material which exhibits a change in volume and/or a change in refractive index in the presence of a given chemical. The change in volume and/or refractive index gives a change in an optical path length through the probe which can be measured interferometrically. | 01-14-2010 |

| 20100058280 | BULK IMAGE MODELING FOR OPTICAL PROXIMITY CORRECTION - A method is described herein for predicting lateral position information about a feature represented in an integrated circuit layout for use with an integrated circuit fabrication process, where the process projects an image onto a resist. The method includes providing a lateral distribution of intensity values of the image at different depths with the resist. Next, the lateral position of an edge point of the feature is predicted in dependence upon a particular resist development time, and further in dependence upon the image intensity values at more than one depth within the resist. | 03-04-2010 |

| 20090125313 | AUDIO CODING USING UPMIX - A method for decoding a multi-audio-object signal having audio signals of first and second types encoded therein, the multi-audio-object signal having a downmix signal and side information having level information of the audio signals of the first and second types in a first predetermined time/frequency resolution, the method including computing a prediction coefficient matrix C based on the level information; and up-mixing the downmix signal based on the prediction coefficients to obtain a first and/or a second up-mix audio signal approximating the audio signals of the first and second types, respectively, wherein up-mixing yields the first and/or second up-mix signals S | 05-14-2009 |
| 20090125314 | AUDIO CODING USING DOWNMIX - An audio decoder for decoding a multi-audio-object signal having an audio signal of a first type and an audio signal of a second type encoded therein is described, the multi-audio-object signal having a downmix signal and side information, the side information having level information of the audio signals of the first and second types in a first predetermined time/frequency resolution, and a residual signal specifying residual level values in a second predetermined time/frequency resolution, the audio decoder having a processor for computing prediction coefficients based on the level information; and an up-mixer for up-mixing the downmix signal based on the prediction coefficients and the residual signal to obtain a first up-mix audio signal approximating the audio signal of the first type and/or a second up-mix audio signal approximating the audio signal of the second type. | 05-14-2009 |
| 20100094631 | APPARATUS AND METHOD FOR SYNTHESIZING AN OUTPUT SIGNAL - An apparatus for synthesizing a rendered output signal having a first audio channel and a second audio channel includes a decorrelator stage for generating a decorrelator signal based on a downmix signal, and a combiner for performing a weighted combination of the downmix signal and a decorrelated signal based on parametric audio object information, downmix information and target rendering information. The combiner solves the problem of optimally combining matrixing with decorrelation for a high quality stereo scene reproduction of a number of individual audio objects using a multichannel downmix. | 04-15-2010 |
| 20110264456 | BINAURAL RENDERING OF A MULTI-CHANNEL AUDIO SIGNAL - Binaural rendering a multi-channel audio signal into a binaural output signal is described. The multi-channel audio signal has a stereo downmix signal into which a plurality of audio signals are downmixed, and side information having a downmix information, as well as object level information of the plurality of audio signals and inter-object cross correlation information. Based on a first rendering prescription, a preliminary binaural signal is computed from the first and second channels of the stereo downmix signal. A decorrelated signal is generated as an perceptual equivalent to a mono downmix of the first and second channels of the stereo downmix signal being, however, decorrelated to the mono downmix. Depending on a second rendering prescription, a corrective binaural signal is computed from the decorrelated signal and the preliminary binaural signal is mixed with the corrective binaural signal to obtain the binaural output signal. | 10-27-2011 |

| 20090306972 | Dropout Concealment for a Multi-Channel Arrangement - A method conceals dropouts in one or more audio channels of a multi-channel arrangement. The method maps transmitted signals into a frequency domain during an error-free signal transmission of two or more channels. A magnitude spectra and spectral filter coefficients are derived. The spectral filter coefficients relate the magnitude spectrum of the audio channel to the magnitude spectrum of at least one other channel. When a dropout occurs, a replacement signal is generated through the filter coefficients and a substitution signal. The filter coefficients may be generated prior to the detection of the dropout. | 12-10-2009 |

| 20120106733 | SYSTEM AND METHOD FOR DATA ENCRYPTION - A computer executable encryption/decryption system implementing a provably unbreakable cyphering technique having a repeat period of at least a googol with every computer/detachable device having its own unique provably unbreakable encryption. The system comprises an encryption processor, a Googol Production Engine module comprising a plurality of virtual wheels, a digital curtain module comprising a symbol encryption table, a decider module for selecting one of the input data element and the inert ingredient for encryption via the digital curtain, a column selector (Driveshaft) module for advancing the columns in the digital curtain module with a repeat of over a googol for encryption output, and a communications interface operatively connected to computer readable memory and the encryption processor. In an embodiment, the most recent encryption location becomes a new starting coordinate for the next encryption. With precision and controlled variables, the encryption process changes both with and within each encryption. | 05-03-2012 |
