International Classification:

G01N 1/00

US Classification:

356 38

Abstract:

The invention includes sensors and sensing methods for determining cell morphology and/or chemical composition of an analyte. A porous substrate exhibiting a first optical signal is exposed to a target analyte and subsequently monitored for changes in the optical signal. More specifically, a photonic or porous substrate having a well-defined and highly tunable reflectivity or transmission spectrum, such as porous silicon (Si), porous alumina, porous Ge, porous GaAs, porous SiO2 and porous polymer, is used for example. A porous or photonic substrate is exposed to an analyte, such as a cell or other macromolecule, and changes in the scattered light are observed over time to determine cell morphology and/or chemical composition of the analyte using the substrate.

US Classification:

705 34, 705 11, 705 261, 705 40

Abstract:

An arrangement collects data from disparate system back-end sources, such as a contracts system, a billing system, a service provisioning system, and analyzes the data to determine whether any inconsistencies exist. If so, the system issues a modification request to compensate for the inconsistency.

Abstract:

The invention provides porous particles that produce a predetermined optical response and that may be manipulated magnetically. A preferred particle of the invention has a porous structure that produces a predetermined optical response and magnetic material adhered to the particle. Another preferred particle is amphiphilic. The optical response provided by a particle of the invention enables particles of the invention to be used in sensing, labeling, signaling, display and many other applications. The magnetic nature of the present magnetic particles permits the particles themselves to be manipulated, e. g. , vibrated, moved and re-oriented. The porous particles can also be used to control, move, and/or deliver small volumes of liquids and solids associated with the particles.

International Classification:

G10L 19/00

US Classification:

704200100

Abstract:

The automatic and optimal selection of coding parameter values according to analyses of coding trials is disclosed. The Neural Encoding Model (NEM) provides a method for providing a quantitative measure of the likelihood that a human observer can distinguish an original sensory signal from an approximation thereof, thus providing a metric by which the effect of various coding parameters may be analyzed and optimized. Optimal coding parameters can be defined for an entire data set, such as a digitized audio file, or for discrete portions of the data set. A trial coded data set or portion thereof is analyzed to determining if certain coding parameters have been assigned optimal values. If not, parameter manipulation is performed in an intelligent order and the objective analysis is repeated until predetermined objective perceptual distance criteria are achieved.

US Classification:

708409, 702189, 708208, 708403

Abstract:

A method for improving precision in FFT calculations. For each iteration in an FFT implementation, a constant normalization multiplier is inserted such that the dynamic ranges of the input and output are the same. The final FFT output is multiplied by a constant normalization factor given by the number of iterations and the constant normalization multiplier.

International Classification:

G06F 7/38

US Classification:

708551

Abstract:

Round-off error in fixed-point arithmetic is minimized by changing the magnitudes of two multipliers simultaneously. The dynamic range of an intermediate output is thus maximized to increase computation precision. A much smaller round-off error, caused by fixed-point arithmetic, thus results.

Yang Li - South Plainfield NJ, US

International Classification:

G10L 19/00

US Classification:

704501, 704E19001

Abstract:

Source signals, such as audio and/or video data, are encoded into multiple, consecutive frequency bands. These bands are referred to as coding layers. Rather than performing complex bit-slice operations, a disclosed technique enables an agile and simplified response to transmission channel throughput variations. Specifically, if it becomes necessary to restrict the rate of data transmission to avoid receiver buffer underflow resulting from transmission channel degradation, layers from the transmitted signal are omitted, beginning with the highest frequency bands. Efficient and agile bit rate scalability during data streaming through wired or wireless networks and during local playback is thus enabled.
