摘要： A method for joint scalar quantization is disclosed, characterized in that, transforming the original variables into intermediate variables according to a special transforming relationship; according to the variance of the intermediate variables, quantizing, feedbacking and transmitting the intermediate variables; when the original variables are needed, transforming the intermediate variables into the original variables according to the special transforming relationship. Two schemes about the intermediate variables quantization are also provided to adapt to the different system requirements. Further, based on the joint scalar quantization schemes said above, two methods for adaptively adjusting scalar quantization level according to the interrelation among signals are provided.

摘要： Methods and systems are provided for control operation of a boost converter. The boost converter includes an input, an output, and a plurality of paths electrically connecting the input to the output. The boost converter also includes a plurality of switches disposed along the paths to control current flow between the input and the output. The system includes a controller. The controller receives a desired current to be supplied at the output. The controller determines which of the paths to utilize based at least in part on the desired current. The controller controls the switches based at least in part on the determination of which of the paths to utilize.

摘要： Measured are received power of a first signal received from a first entity, and received power of a second signal received from a second entity. A gain factor (or a matrix of gain factors if multiple antennas are used) is determined using the measured received powers of the first signal and of the second signal. If transmit power from the apparatus to the second entity is considered as the benchmark, the second signal is forwarded from the apparatus to the first entity using a second signal transmit power that is determined using the gain factor. Or, if transmit power from the apparatus to the first entity is considered as the benchmark, the first signal is forwarded from the apparatus to the second entity using a first signal transmit power that is determined using the gain factor. Method, apparatus, and memory storing computer program are detailed.

摘要： A computer-assisted diagnostic (CAD) method and apparatus are described for the enhancement and detection of suspicious regions in digital X-ray images, with particular emphasis on early cancer detection using digital mammography. An objective is to improve the sensitivity of detection of suspicious areas such as masses, while maintaining a low false positive detection rate, and to classify masses as benign or malignant. A modular CAD technique has been developed as a potentially automatic and/or second-opinion method for mass detection and classification in digital mammography that may in turn be readily modified for application with different digital X-ray detectors with varying gray-scale and resolution characteristics. The method consists of using a plurality of CAD modules to preprocess and enhance image features in the gray-level, the directional texture, and the morphological domains.
