摘要： A system and method for detecting ventricular fibrillation based on chaos theory. A Poincare plot of the amplitude of the ECG signal is generated and used to detect the presence of fibrillation. The plot is monitored for the data points drifting off the plot axes. Upon detecting such drift, the presence of ventricular fibrillation is confirmed. The system and method may be used as a primary detection scheme or as a backup system to reconfirm fibrillation detection using conventional techniques.

摘要： A buffer size for a router configured to receive packets transmitted through a communications network is temporarily increased at a time instant corresponding to an onset of congestion of the router for a time period that may be approximately equal to a round-trip packet time in the network. The increase in buffer size may be accomplished by providing an auxiliary storage area for packets that would otherwise be stored in a queue at the router, for example an auxiliary storage area associated with a physical storage device external to the router.

摘要： A queue length for a queue storing packets transmitted through a communications network is temporarily increased at a time instant corresponding to an onset of congestion of the queue for a time period. Increasing the queue length in this way may be accommodated by providing an auxiliary storage area for packets that would otherwise be stored in the queue. The auxiliary storage area may be associated with a different physical storage device than a storage device associated with the queue.

摘要： An electrosurgery blade active electrode having a plurality of discrete electrical discharge points along a blade edge. A plurality of distinct points are provided for current discharge, facilitating controlled evenly distributed current through the tissue. The more stable discharge allows cutting with reduced current thus substantially reducing problems of the electrode sticking to the tissue and reducing damage to surrounding tissue. Furthermore, the cutting speed is increased and the smoke generated in the cutting process is decreased with use of the inventive blade. The electrosurgery blade of the invention may also include a plurality of grooves or channels on the side of the blade leading from the blade edge to the back of the blade away from the cutting edge to facilitate the escape of heated gasses from the area of the cut.

摘要： A tennis racket with handle and head coupled with an interconnection insert provides torsional elasticity and vibration damping. The racket handle has a mating extension extending toward the head and the head includes a mating extension extending toward the handle such that the handle and head mate together at the mating extensions. The handle extension has a tongue with two bores and a pair of elastic bushings extending through bores. The head mating extension comprises a recess or U-shaped channel which receives the tongue and includes a pair of securing pins extending through the bushings and being rigidly secured to the sides of the recess or channel. The bushings and pins are positioned transverse to the longitudinal extent of the handle and parallel to the racket face. The bushings perform a shock absorbing function, provide torsional elasticity and control the racket stiffness. A stabilizing bushing may be added parallel to the first two bushings and it extends through the tongue and through the sides of the recess or channel. A stabilizing pin then extends through this bushing.

摘要： The present invention provides a system and method for characterizing cardiac fibrillation using wavelet transforms. By characterizing the seriousness of a fibrillation episode, a defibrillation shock may be delivered to the heart with less excess energy than conventional ICDs. A wavelet transform is performed on a digitized ECG using a second derivative weight function and the results are analyzed for missing "peaks" in the data. The more serious the fibrillation, the more peaks will be missing from the data. This information may then used to modify the voltage of the defibrillation shocks as a function of the seriousness of the fibrillation.
