A speech recognition system recognizes an input speech signal by using a first speech recognizer and a second speech recognizer each coupled to a decision module. Each of the first and second speech recognizers outputs first and second recognized speech texts and first and second associated confidence scores, respectively, and the decision module selects either the first or the second speech text depending upon which of the first or second confidence score is higher. The decision module may also adjust the first and second confidence scores to generate first and second adjusted confidence scores, respectively, and select either the first or second speech text depending upon which of the first or second adjusted confidence scores is higher. The first and second confidence scores may be adjusted based upon the location of a speaker, the identity or accent of the speaker, the context of the speech, and the like.

The present invention provides a technique for reducing the peak power of a combined signal that has a first signal of a first modulation type and a second signal of a second modulation type. Based on the combined signal, peak reduction distortion is determined. The peak reduction distortion is configured such that, if applied to the entirety of the combined signal, excessive peaks throughout the combined signal would be reduced. However, instead of applying the entirety of the peak reduction distortion, a selected portion of the peak reduction distortion is applied to a corresponding portion of the combined signal to reduce the peak power of the combined signal.

Downlink power control commands are mapped to resources used for uplink communications within a wireless communication system. An eNode B receives communications from UEs and determines the resources used by the UEs for those transmissions on the uplink which are transmitted at non-optimum power levels. Power control messages are formulated wherein the location of the power control commands is mapped to particular resources used by the UEs for their uplink transmissions. This facilitates the eNode B to dynamically assign resources for the power control commands while permitting the UEs to decode the power control messages to adjust their power accordingly.

The invention provides a series of reagent compositions and methods for making and amplifying novel cDNA based probe sets from RNA samples to improve analysis with gene expression arrays. The methods globally produce probe sets with common universal linkers at one or both ends, called WRAP-Probes, wherein the linkers do not bind to the target sequences and they can efficiently bind added reporters to the probes. The universal linkers are also designed as primer binding sites for copying and amplifying the probes, either linearly with one linker, or exponentially with double linkers. The capacity to globally and exponentially amplify the probe set by PCR is a primary advantage. Adding reporters by terminal linkers also improves quantification since each probe gets equivalent signaling. The invention allows expression analysis of small research, clinical and forensic samples to enable improved diagnostics, drug discovery, therapeutic monitoring, and medical, agricultural and general research.

An imaging system employing a coded aperture mask having multiple pinholes is provided. The coded aperture mask is placed at a radiation source to pass the radiation through. The radiation impinges on, and passes through an object, which alters the radiation by absorption and / or scattering. Upon passing through the object, the radiation is detected at a detector plane to form an encoded image, which includes information on the absorption and / or scattering caused by the material and structural attributes of the object. The encoded image is decoded to provide a reconstructed image of the object. Because the coded aperture mask includes multiple pinholes, the radiation intensity is greater than a comparable system employing a single pinhole, thereby enabling a higher resolution. Further, the decoding of the encoded image can be performed to generate multiple images of the object at different distances from the detector plane. Methods and programs for operating the imaging system are also disclosed.

A method for utilizing polarization as a scheme for fluorescence removal from UV Raman spectra collected in a standoff detection scheme has been invented. In this scheme, a linearly polarized ultraviolet (UV) laser interacts with a material on a surface or in a container. The material generates Raman scattering with polarization contributions relative to that of the laser. The material possibly fluoresces as well, but the fluorescence is generally unpolarized. By subtracting a scaled version of the perpendicular component from the parallel component of the returned signal both relative to the laser source polarization—it is possible to generate a spectrum that is fluorescence free and contains the strongest features of the Raman scattered light.
