Abstract: Techniques for efficiently encoding an input signal are described. In one design, a generalized encoder encodes the input signal (e.g., an audio signal) based on at least one detector and multiple encoders. The at least one detector may include a signal activity detector, a noise-like signal detector, a sparseness detector, some other detector, or a combination thereof. The multiple encoders may include a silence encoder, a noise-like signal encoder, a time-domain encoder, a transform-domain encoder, some other encoder, or a combination thereof. The characteristics of the input signal may be determined based on the at least one detector. An encoder may be selected from among the multiple encoders based on the characteristics of the input signal. The input signal may be encoded based on the selected encoder. The input signal may include a sequence of frames, and detection and encoding may be performed for each frame.

Abstract: A modulator is disclosed for creating a pressure pulse in a fluid-filled well. The modulator comprises a tool body on which a plurality of extendable arms (6) are mounted. The arms (6) may be retracted into a stowed position substantially adjacent the tool body, or may be extended to meet the wall of the borehole (2). The arms (6) are preferably resilient bowsprings that may be flexed outwards from the tool by means of an actuator pushing on at least one end of the springs. A flexible valve sleeve (5) or bag is suspended between the arms (6) and cooperates with a valve (4) mounted adjacent the sleeve on the tool body. The valve sleeve (5) creates a fluid-flow path through the valve (4), and in operation, the valve (4) closes one end of the valve sleeve (5) to create the pressure pulse. Sealing of the valve sleeve against the wall of the well is a result of the fluid pressure inflating the sleeve against the well wall. As a result, sealing takes place over an extended area of the bag and is dynamically responsive to changes in fluid flow or pressure.

Abstract: Techniques for creating 3-D movies allow improved control over camera positioning parameters and editing of depth in post process to provide for a smoother variation in the viewer's convergence distance and a more pleasant viewing experience. A director can define reference parameters related to a desired viewing experience, and camera positioning parameters are derived therefrom. A depth script specifying piecewise continuous variations in reference parameters can be applied in post process to generate 3-D  shots, scenes, or movies. These techniques can be applied in both computer generated and live action 3-D  movies.
