摘要:
An optical conductor of the monomode type comprises an optical fiber covered by a primary layer surrounded by a secondary layer. To reduce the cost of fabricating the conductor, the secondary layer includes an outer part of a thermoplastics material the apparent viscosity of which at the melting point is at most approximately 100 Pascal-second at a shear rate at least equal to 100 s.sup.-1. The primary layer and the inner part of the secondary layer are made from a resin that can be cross-linked using ultraviolet radiation, for example.

A system and method are provided for mixing song data based on measure groupings. A player or program may recognize measure groupings in a song through identifying cuepoints. The player or program may use the cuepoints and/or other identifiers of measure groupings to generate a transition between the song and other songs. Parts of one or both songs may be time-stretched, or frames may be added or deleted, such that the beats in both songs are substantially aligned during the transition. The system and method may also involve altering the sequence of frames in one or both of the songs, so that the transition may have various sonic qualities as desired by a user. A choice of transition modes may be provided via a user interface that allow the user some control over when and how transitions between songs are executed.
摘要:
A system and method are provided for generating cuepoints for mixing song data. One or more people may listen to a song and identify measure groupings within the song. The one or more people might generate markings corresponding to these measure groupings and submit the markings to a cuepoint generation system. The markings may then be reconciled into cuepoints that may be used for mixing the song with other song data. In some embodiments, the cuepoints may be adjusted based on characteristics of the particular songs that are to be mixed together.

An epicardial lead is passively fixed in a pericardial space by a passive fixation member. The passive fixation member extends from a distal portion of an epicardial lead and acts against a pericardial layer and an epicardial layer to hold the lead in place. The epicardial lead may include an electrode that is connected to a conductor that extends from a distal portion of the lead. In some embodiments the epicardial lead includes a material that promotes fibrosis to fix the lead to heart tissue. The passive fixation member may include a shocking coil.

An exemplary method includes accessing cardiac information acquired via a catheter located at various positions in a venous network of a heart of a patient wherein the cardiac information comprises position information with respect to time for one or more electrodes of the catheter; performing a principal component analysis on at least some of the position information; and selecting at least one component of the principal component analysis to represent an axis of a cardiac coordinate system. Various other methods, devices, systems, etc., are also disclosed.

An exemplary method includes use of a multielectrode device that can help position a cardiac stimulation lead to an optimal site in the heart based at least in part on cardiac motion information acquired via the multielectrode device and one or more pairs of current delivery electrodes that establish potential fields (e.g., for use as a coordinate system). An exemplary mutlielectrode device may be a multielectrode catheter or a multifilar, electrode-bearing guidewire. Various other exemplary methods, devices, systems, etc., are also disclosed.
摘要:
Encoding a video signal according to a scalable video coding (SVC) technique employs two different encoding paths for the base layer and the enhancement layers respectively, whereby the two encoding paths share common hardware encoding modules. For example, a control module can route received video information associated with the base layer directly to the hardware encoder modules for encoding, while routing video information associated with the enhancement layers to an upscaler. The upscaled video information is then provided to the hardware encoder module for processing in similar fashion to the base layer information. The hardware encoder provides encoded video information to another control module, which determines whether to route the information to a hardware or software entropy encoder, based on whether the encoded video information is associated with the base layer or an enhancement layer, respectively.
摘要:
An exemplary method includes providing at least two-dimensional position information, for at least two points in time, for an electrode located in a cardiac space; determining a local estimator based on the position information; and, based at least in part on the determined local estimator, selecting a configuration for delivering a cardiac pacing therapy or diagnosing a cardiac condition. Exemplary methods for regional estimators and exemplary methods for global estimators are also disclosed along with devices and systems configured to perform various methods.

An exemplary method includes providing a mechanical activation time (MA time) for a myocardial location, the location defined at least in part by an electrode and the mechanical activation time determined at least in part by movement of the electrode; providing an electrical activation time (EA time) for the myocardial location; and determining an electromechanical delay (EMD) for the myocardial location based on the difference between the mechanical activation time (MA time) and the electrical activation time (EA time).
