  • Publication number: 20070272260
    Abstract: An implantable interface system for a medical device system providing selective interconnectivity between conduits and therapy elements. The interface system contains connecting elements that each provide a robust connection between a selected conduit and a selected therapy element. The interface system enables the use of a surplus of therapy elements so that treatment to the same site (in the case of electrode migration or failure), or to different sites but within the spatial domain of the interface's elements may be delivered through the spare/excess therapy elements without the need for additional major surgical procedures.

  • Publication number: 20070271066
    Abstract: A method, computer program, and system for real-time signal analysis providing characterization of temporally-evolving densities and distributions of signal features of arbitrary-type signals in a moving time window by tracking output of order statistic filters (also known as percentile, quantile, or rank-order filters). Given a raw input signal of arbitrary type, origin, or scale, the present invention enables automated quantification and detection of changes in the distribution of any set of quantifiable features of that signal as they occur in time. Furthermore, the present invention's ability to rapidly and accurately detect changes in certain features of an input signal can also enable prediction in cases where the detected changes associated with an increased likelihood of future signal changes.

  • Publication number: 20070242227
    Abstract: The present invention relates generally to optical imaging and specifically to methods and systems for generating observable real images. The method consists of steps in configuring an image source and optical components, and defining the position of an observer in such a way that a binocular observation leads to a perception of a three-dimensional object being located in front of a background, and/or “hanging in mid-air” in front of an apparatus designed in accordance with the present invention. Particular embodiments of the invention may include various apparatus for implementing the method.

  • Publication number: 20060253512
    Abstract: Various components of the present invention are collectively designated as Adaptive Real-Time Embodiments for Multivariate Investigation of Signals (ARTEMIS). It is a method, processes, and apparatus for measurement and analysis of variables of different type and origin. In this invention, different features of a variable can be quantified either locally as individual events, or on an arbitrary spatio-temporal scale as scalar fields in properly chosen threshold space. The method proposed herein overcomes limitations of the prior art by directly processing the data in real-time in the analog domain, identifying the events of interest so that continuous digitization and digital processing is not required, performing direct, noise-resistant measurements of salient signal characteristics, and outputting a signal proportional to these characteristics that can be digitized without the need for highspeed front-end sampling. The application areas of ARTEMIS are numerous, e.g.

  • Publication number: 20050207653
    Abstract: The present invention relates to methods for conditioning, representation, modeling, characterization, identification, comparison, and analysis of variables. In particular, this invention is specially adapted for analysis of line objects such as, for example, human handwritten signatures. This invention also relates to generic measurement systems and processes, and to methods and corresponding apparatus for measuring which extend to different applications and provide results other than instantaneous values of variables. The invention further relates to post-processing analysis of measured variables and to statistical analysis. It is a method, processes, and apparatus for measurement and analysis of variables of different type and origin. In particular, this invention is specially adapted for analysis of (parametric) line objects such as, for example, human handwritten signatures. Particular embodiments of the invention may include various computer programs and simulation tools.

  • Publication number: 20050165879
    Abstract: Various components of the present invention are collectively designated as Analysis of Variables Through Analog Representation (AVATAR). It is a method, processes, and apparatus for measurement and analysis of variables of different type and origin. AVATAR offers an analog solution to those problems of the analysis of variables which are normally handled by digital means. The invention allows (a) the improved perception of the measurements through geometrical analogies, (b) effective solutions of the existing computational problems of the order statistic methods, and (c) extended applicability of these methods to analysis of variables. The invention employs transformation of discrete or continuous variables into normalized continuous scalar fields, that is, into objects with mathematical properties of density and/or cumulative distribution functions. In addition to dependence on the displacement coordinates (thresholds), these objects can also depend on other parameters, including spatial coordinates (e.g.
