Abstract: A fitting provided for earbud-type personal audio speakers may be formed as a homogeneous, integral component molded from an elastomeric polymer, such as silicone, urethane, or other elastomeric resins. A sleeve fitted to the speaker engages the fitting to the speaker, while ribs extending from the sleeve terminate in flutes conformal to an ear canal of a user. Axial insertion of the fitting and speaker into an ear of a user results in localized deflection of flutes and ribs in order to accommodate size and shape of an ear canal, resulting in transmission of sound from the speaker directly through the sleeve into an ear canal of a user, while also permitting environmental sounds to pass along a parallel path over the outside of the sleeve, between the ribs.

Abstract: The present invention relates to a video tracker which allows automatic tracking of a selected area over video frames. Motion of the selected area is defined by a parametric motion model. In addition to simple displacement of the area it can also detect motions such as rotation, scaling and shear depending on the motion model. The invention realizes the tracking of the selected area by estimating the parameters of this motion model in the complex discrete wavelet domain. The invention can achieve the result in a non-iterative direct way. Estimation carried out in the complex discrete wavelet domain provides a robust tracking opportunity without being effected by noise and illumination changes in the video as opposed to the intensity-based methods. The invention can easily be adapted to many fields in addition to video tracking.

Abstract: The tracking and compensation of patient motion during a magnetic resonance imaging (MRI) acquisition is an unsolved problem. A self-encoded marker where each feature on the pattern is augmented with a 2-D barcode is provided. Hence, the marker can be tracked even if it is not completely visible in the camera image. Furthermore, it offers considerable advantages over a simple checkerboard marker in terms of processing speed, since it makes the correspondence search of feature points and marker-model coordinates, which are required for the pose estimation, redundant. Significantly improved accuracy is obtained for both phantom experiments and in-vivo experiments with substantial patient motion. In an alternative aspect, a marker having non-coplanar features can be employed to provide improved motion tracking. Such a marker provides depth cues that can be exploited to improve motion tracking. The aspects of non-coplanar patterns and self-encoded patterns can be practiced independently or in combination.

Abstract: Systems and methods for detecting obstacles using a single camera positioned on an apparatus in motion over an area of motion, or stationary over a moving area of motion. In an example method, a video stream of images is captured of the area of motion. The images in the video stream may be corrected for lens distortion prior to further processing. An Nth image frame is selected from a sequence of N images in the video stream. A set of N?1 difference images is calculated by subtracting each of the N?1 previous images from the Nth image. The N?1 difference images are added to one another to generate a combined difference image. A perspective transformation is performed on the combined difference image to generate a transformed image. The transformed image is analyzed to detect edges of obstacles in the transformed image. A signal indicating detection of an obstacle in the area of motion may then be generated.

Abstract: Compressed sensing (CS) estimation approaches rely on a priori sparsity to significantly reduce the number of samples needed to provide high sampling fidelity, relative to the normal Shannon-Nyquist limit. Accordingly, CS approaches are of considerable interest for detector multiplexing in applications which have inherently sparse signals (e.g., the two correlated photon detection events in PET imaging). However, CS approaches also tend to fare poorly in the presence of noise, which has limited their applicability in practice. In this work, we show that CS estimation can be used to provide an estimate of the support of an image. This estimated support is then used as a constraint for maximum likelihood image reconstruction. This approach has robust noise performance and provides high reconstruction fidelity.
