Abstract: In one embodiment, an X-ray inspection system may access a first set of X-ray images of one or more first samples that are labeled as being non-conforming. The system may adjust a classification algorithm based on the first set of X-ray images. The classification algorithm may classify samples into conforming or non-conforming categories based on an analysis of corresponding X-ray images. The system may analyze a second set of X-ray images of a number of second samples using the adjusted classification algorithm. The second samples may be previously inspected samples that have been classified as conforming by the classification algorithm during a previous analysis before the classification algorithm is adjusted. The system may identify one or more of the second samples from the second set of X-ray images. Each identified second sample may be classified as non-conforming by the adjusted classification algorithm.

Abstract: A speech signal processing approach modifies the amplitudes of pulses within a multi-pulse sequence to improve and/or modify the perceived quality of reconstructed speech. According to one embodiment that is consistent with the present invention, an input frame processing arrangement generates the short-term characteristics of an input speech signal and also a target vector. The processing arrangement includes an analyzer that operates to provide an optimal analysis, from a maximum-likelihood standpoint, with respect to determining the best possible pulse sequence to match the target. The analyzer receives the target vector and the short term characteristics and generates a plurality of sequences of variable-amplitude pulses, each of said sequences having a different average amplitude value.

Abstract: The present invention is directed to audio processing including IP telephony audio processing. Voice-over-IP terminals used in phone terminal applications benefit from a low-power implementation suitable for the limited chassis area of these devices. According to an example embodiment of the present invention, a programmable audio processor chip is adapted to process voice data for IP communications. The chip includes a DSP voice compression device adapted to compress voice data, and audio processing circuitry programmed with an audio processing software application adapted to process the compressed voice data. The chip further includes an IP network stack adapted to store and process IP data. The IP data includes protocols for processing the compressed voice data via an IP network. A communication stack is also included in the chip and is adapted to store and process communications data. The communications data includes audio processing protocols for processing the compressed voice data.
