An RF PA operable in two or more selectable power ranges is disclosed. Switches configure the circuit for each range such that an amplifier device corresponding to the range provides final amplification, and all lower power amplifier devices also amplify the signal. An exemplary design includes a low power amplifier configurable for operation solo, or in parallel with a medium power amplifier, to deliver an appropriately matched signal either directly to the RF PA output, or first to the input of a high power amplifier for the highest power range. The signal in all ranges of the exemplary design is conditioned in part by the matching circuitry disposed between the high power amplifier and the RF PA output, which traverses no switches in high power range operation. The entire RF PA, including switches, control and matching circuitry, is fabricated on a single monolithic integrated circuit, an achievement may be facilitated by UTSI CMOS processing.

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.

In one example, a method includes receiving, by a server and from a plurality of computing devices, data representative of a group of gesture-shortcut pairs that each include a gesture having been detected by at least one computing device from the plurality of computing devices and a shortcut associated with the detected gesture, and wherein the shortcut corresponds to an operation to be executed by the at least one from the plurality of computing devices. The method includes sorting the data representative of each respective gesture-shortcut pair from the group of gesture-shortcut pairs into at least two subgroups, a first subgroup including the first gesture-shortcut pair and a second including the second gesture-shortcut pair, the sorting being based on detected similarities between at least one of each respective gesture from the group of gesture-shortcut pairs and each respective shortcut from the group of gesture-shortcut pairs.

A sandwich strip coupled coupler implemented in a multi-layer substrate, such as a multi-layer printed circuit board. In one example, the sandwich strip coupled coupler includes a main arm having a first main arm section and a second main arm section disposed above the first main arm section, the first and second main arm sections being electrically connected together, and a coupled arm disposed between the first and second main arm sections, the first main arm section, the coupled arm and the second main arm section forming a sandwich structure.

A power amplifier with stacked, serially connected, field effect transistors is described. DC control voltage inputs are fed to the gates of each transistor. Capacitors are coupled to the transistors. The inputs and the capacitors are controlled to minimize generation of non-linearities of each field effect transistor and/or to maximize cancellation of distortions between the field effect transistors of the power amplifier in order to improve linearity of the power amplifier output.

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.

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.

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.
