Abstract: Systems and methods for computer-implemented pre-optimization of input data before further processing thereof by a computer-implemented analyzation process, such as optical character recognition (OCR). A cooperative model is employed that combines one or more supervised-learning based inspector sub-models, and one or more filter sub-models that operating in series with the inspector sub-model(s). The inspectors first receive the input data and calculate one predicted transformation parameters then used to perform transformations on the input data. The inspector-transformed data is then passed to the filters, which derive respective convolution kernels and apply same to the inspector-transformed data before passing same to the OCR or other analyzation process. The inspectors may be pretrained with different training data.

Abstract: The invention provides a method to compute the mixed potential contributions to electric and magnetic field in multilayered media, which can be applied in microwave engineering, integrated circuit analysis, and remote sensing. The Spectral Differential Equation Approximation Method (SDEAM) for solving Michalski-Zheng's mixed-potential Green's functions in fully shielded, partially open, and fully open multilayered media are described. The main advantage of SDEAM over other methods is that for a fixed location of the source elevation z?, it does not require fitting from scratch for every z, z?, and ? combination. Because of this advantage, SDEAM can be superior in both performance and accuracy to other existing methods. The well-established boundary value problem numerical solvers also provide SDEAM with robustness for miscellaneous planar multilayered structures.

Abstract: A printer driver receives printing data (e.g., data to be printed on a surface of the smart card) and encoding data from an application. The application may expose a device-independent printing interface with one or more escape functions for sending device-specific data (e.g., smart card encoding data). The printer driver generates integrated data comprising the printing data and the encoding data. A command coordinator (e.g., a language monitor) extracts printing commands and encoding commands from integrated data, sends printing commands to a printer device, and sends encoding commands to an encoder. The encoder can be recognized as a device that is separate from the printer device, even where the encoder and the printer device are housed in the same physical device. Described aspects can be used in a network environment with multiple client devices that share printing and encoding devices.

A heat sink of the printed circuit board extends through the housing from an interior of the housing to an exterior of the housing. The printed circuit board is disposed within the main body such that the heat sink is located in an air-flow path through the main body.

Abstract: The present invention provides a method of and system for dynamically loading an executable composite software application, for use on a user device. An enterprise universe including multiple application modules is maintained, with each application module being configured to perform a particular functionality within the software application. This universe is filtered in terms of a particular environment definition to result in an environment subset of application modules, wherein the environment definition defines criteria according to which application modules exist in the environment. In response to receiving a container launch request from a user device, one or more application modules from the environment subset is launched as the executable composite software application on the user device through a container module associated with the user device.

Abstract: A process for recovering metals involving ion exchange comprising the step of recovering metal species from an ion exchange resin by elution of the resin with an eluent system containing (i) a first sulphite component comprising at least one of sulphite and bisulphite ion; and (ii) a second eluting component comprising any species which favours the ion exchange or desorption of a metal species from the resin during elution wherein the presence of the sulphite component (i) increases metal elution efficiency relative to the situation where an eluent comprises the second eluting component alone.

Abstract: An antenna installation for cellular radio has four antennas ANT 1A, ANT 1B, ANT 2 and ANT 3 mounted on respective sides of a rectangular support 48 and giving rise to four antenna coverage sectors 1A and 1B and sectors 2 and 3. A splitter/combiner unit (SCU) receives three signals (1, 2 and 3) from a base station, and splits signal 1 into two signals 1A and 1B of equal power. The splitter/combiner 5C1 acts as a splitter in transmit mode and a combiner in receive mode. The signals 1A, 1B, 2 and 3 are connected to antennas ANT 1A, ANT 1B ANT 2 and ANT 3 respectively. Split signal antennas ANT 1A, ANT 1B carrying the same transmit signal are not adjacent to one another: they are separated from one another by another sector associated with a different signal, and therefore do not overlap sufficiently to affect communications significantly. This avoids creation of signal interference regions in antenna coverage areas which would lead to signals being partially unobtainable there.
