Abstract: An audio reproduction apparatus is shown and includes an amplifier with a power amplification stage having transistors in a push-pull arrangement. A bias generator biases the transistors with a standing current. A processor receives a data stream comprising digital samples of an analog audio signal and analyzes the peak level of each group. It then determines the appropriate standing currents to maintain Class A operation of the power amplification stage given the peak levels of each of the groups. A digital to analog converter produces an analog input signal for the input stage of the amplifier from the data stream. A feedforward path between the processor and the bias generator allows the standing current to be adjusted prior to the arrival of the analog input signal in the power amplification stage.

Abstract: Techniques are disclosed for performing flood-fill operations on vector artwork. In one embodiment, a region under a point of interest (POI) of vector artwork is rasterized and flood-filled, and an initial bounding shape around that area is used as a first guess as to the area to be filled. In other cases, the initial bounding shape is created around some initial area that includes the POI (no rasterization). In any such case, vector objects having bounding shapes that intersect the initial bounding shape are identified and fed into a planar map. After map planarization, a new bounding shape is created around a new area resulting from the planarizing and that includes the POI. In response to that bounding shape not extending beyond the initial bounding shape, a vector-based flood-fill operation can be performed on that new area. The process repeats if a new bounding shape extends beyond previous bounding shape.

Abstract: A data analysis system is proposed for providing fine-grained low latency access to high volume input data from possibly multiple heterogeneous input data sources. The input data is parsed, optionally transformed, indexed, and stored in a horizontally-scalable key-value data repository where it may be accessed using low latency searches. The input data may be compressed into blocks before being stored to minimize storage requirements. The results of searches present input data in its original form. The input data may include access logs, call data records (CDRs), e-mail messages, etc. The system allows a data analyst to efficiently identify information of interest in a very large dynamic data set up to multiple petabytes in size. Once information of interest has been identified, that subset of the large data set can be imported into a dedicated or specialized data analysis system for an additional in-depth investigation and contextual analysis.
