Circuits and methods for providing zero-gap playback of consecutive data streams in portable electronic devices, such as media players, are described. In some embodiments, a circuit includes a decoder circuit configured to receive encoded audio data and to output decoded audio data including data streams associated with a data file and a subsequent data file. Moreover, a predictive circuit, which is electrically coupled to the decoder circuit, is configured to selectively generate additional samples based on samples in the data file, where the additional samples correspond to times after the end of a data stream associated with the data file. Additionally, a filter circuit, which is electrically coupled to the decoder circuit and selectively electrically coupled to the predictive circuit, is configured to selectively combine or blend samples at a beginning of the subsequent data file with the additional samples. Note that the circuit may be included in an integrated circuit.

Provided are a method, medium, and filter for removing discontinuity of an image. The filtering method includes determining the direction or gradient on a boundary of a block of an image divided into blocks of a predetermined size, based on pixel distribution between adjacent blocks and filtering the blocks based on the determined direction or gradient.

A method for treating presbyopia by performing ablative photodecomposition of the corneal surface. The offset image of a variable aperture, such as a variable width slit and variable diameter iris diaphragm, is scanned in a preselected pattern to perform ablative sculpting of predetermined portions of a corneal surface. The scanning is performed to ablate an optical zone sized to match the patient pupil with a peripheral transition zone outside the pupil. The shape of the ablated optical zone is different from the shape of the final optical correction on the anterior surface of the cornea. The optical zone corrects for near-vision centrally and far-vision peripherally. A movable image displacement mechanism enables radial displacement and angular rotation of the profiled beam exiting from the variable aperture. The method enables wide area treatment with a laser having a narrower beam than the treatment area, and can be used in the treatment of many conditions in conjunction with presbyopia such as hyperopia, hyperopic astigmatism and irregular refractive aberrations.

A computer-implemented method for estimating a pose of an articulated object model (4), wherein the articulated object model (4) is a computer based 3D model (1) of a real world object (14) observed by one or more source cameras (9), and wherein the pose of the articulated object model (4) is defined by the spatial location of joints (2) of the articulated object model (4), comprises the steps of

• • obtaining a source image (10) from a video stream;
  • processing the source image (10) to extract a source image segment (13);
  • maintaining, in a database, a set of reference silhouettes, each being associated with an articulated object model (4) and a corresponding reference pose;
  • comparing the source image segment (13) to the reference silhouettes and selecting reference silhouettes by taking into account, for each reference silhouette,
    • a matching error that indicates how closely the reference silhouette matches the source image segment (13) and/or
    • a coherence error that indicates how much the reference pose is consistent with the pose of the same real world object (14) as estimated from a preceding source image (10);
  • retrieving the corresponding reference poses of the articulated object models (4); and
  • computing an estimate of the pose of the articulated object model (4) from the reference poses of the selected reference silhouettes.

The invention discloses a method and system for speech or audio signal bandwidth expansion, which comprises: A. to simulate spectral envelope of the high-frequency signal components in the speech or audio signal. B. to make a synthesis of the said spectrum envelope and the low-frequency signal components corresponding to the high-frequency signal components in the frequency and spatial domain to obtain the reset high-frequency signal components. The invention also discloses the method and system to realize the said bandwidth expansion, the technical scheme offered by which has the advantage of less bit number of coding that can be adaptively adjusted based on the type features of the signals. Besides, by extracting spectrum envelope of the high-frequency signal components, the invention makes the fine structure acted on the low-frequency signal components corresponding frequency and spatial domain to guarantee the correlation between the reset high-frequency signal spectrum and the harmonization of the high-frequency signal spectrum lopped during coding.

Wind turbine with a blade rotor (11) which reduces noise by the inclusion of a set (21) of flexible bristles (23), aligned in at least one row, on the trailing edge (15) of the aerodynamic profile of the blades (11) and protruding over it, which allows the pressure fluctuations to be balanced on both sides of the profile of each blade (11) in the direction of the wind flow.

Electronically programmed signs consist of any array of picture elements (pixels) that can be controlled independently to create an image. Varying the intensity of each pixel and adding multiple colors per pixel will enhance the image quality. It is currently common to have displays that use one, two or three separate colors in a pixel (monochrome, red-green, and red, green and blue) with intensity levels of two, four, eight up to 256 and beyond. Multiple colored pixels can combine colors at various intensity levels to expand the displayable color palette. The number of colors it is possible to display is calculated by the following formula:

While raising the number of intensity levels and colors improves image quality, it also raises the viewer's sensitivity to inconsistencies in both parameters.

A robotic catheter device cartridge may include a finger or a slider block generally disposed in a channel and engaged with a steering wire. The steering wire may control movement of a component having the steering wire engaged thereto when the finger or the slider block is linearly driven in a predetermined direction. The cartridge may be a transseptal cartridge having a transseptal needle connected thereto, a catheter cartridge having a catheter connected thereto, or a sheath cartridge having a sheath connected thereto.

The invention discloses a live broadcast time shift method which is applied to a live broadcast network including a client and a server. The live broadcast time shift of a user on the client is divided into pause and play. The client acquires the time label of a first index file currently parsed by the client according to pause, and acquires the played time of a video clip corresponding to the first index file. The client determines the timestamp of pause in a live broadcast video according to the time label and the played time. When the client receives play, a live broadcast time shift request is sent to the server according to the time shift time and timestamp of play. The live broadcast video in the live broadcast network is parsed and played according to a second index file returned by the server. After a user who watches live broadcast carries out live broadcast time shift, discontinuous screen caused by play screen hysteresis and play delay is reduced, and the user experience is improved. The invention further discloses the client.

Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a video image. Then, the system jointly modifies brightness values of pixels in at least a portion of the video image and an intensity setting of a light source to maintain light output from a display while reducing power consumption by the light source, where the light source is configured to illuminate the display that is configured to display video images. Next, the system adjusts color content in the video image to correct for a dependence of a spectrum of the light source on the intensity setting.
