Title: Catheter with direction orientation
Inventor: TUCKER DAVID JASON
IPC: A61M25/00
Filed: 2005-12-16
Abstract: A regional anesthesia catheter used with a guide such as for example a needle cannula has a distal portion integrally connected to a main portion of the catheter by a junction portion that has a cross-sectional profile different from the distal and main portions, so as to predispose the distal portion of the catheter to move in a given direction when the distal portion is not guided by or constrained by the needle cannula. The cross-sectional profile of the junction portion may be configured in a particular shape, or be constructed to have a flexibility that predisposes the distal portion to bend, curve or move toward a given direction. Once the predisposed direction to which the distal end of the catheter points is known, a physician can readily orient the catheter relative to the needle cannula so that once the distal end of the catheter exits the distal tip of the needle cannula, with the cannula already placed in a position proximate to the desired location to which the distal end of the catheter is to be placed, the physician can readily place the distal end of the catheter at the desired location within the patient.  Instead of only one junction portion, a number of portions of a catheter may be configured to bend at a predefined direction. Further, a catheter may be configured to have a cross sectional profile or a predefined flexibility along its entire length that causes the catheter to bend, curve or move in a predefined direction.

Title: Method and apparatus for implementing seamless playback of continuous media feeds
Inventor: WEAVER DANIEL
IPC: G11B27/031
Filed: 1998-10-19
Abstract: A method and system for storing a continuous feed of video is provided.  According to one aspect of the invention, the continuous feed is encoded in a digital video format to produce a digital data stream. A series of content files is created by repeatedly performing the steps of (1) storing the digital data stream in a current file, and (2) establishing a new file as the current file when the current file satisfies a predetermined condition. If the series of content files contains more than a predetermined amount of the continuous feed, the oldest content file in the series of content files is deleted. Tag information that indicates information about frames contained in the digital data stream is generated. The tag information includes timestamps that indicate timing of frames relative to a beginning of the digital data stream. An initial time value that indicates an absolute time that corresponds to the beginning of the digital data stream. When a request from a client for playback beginning at a specified absolute time is received, the initial time value is subtracted from the specified absolute time to determine a relative time.  The tag information is used to identify a location in the digital data stream that corresponds to the relative time. The digital data stream is then transmitted to the client beginning at the location in the digital data stream that corresponds to the relative time.

Abstract: The invention relates to direct conversion of coal into electricity in a high temperature electrochemical generator in a single step process This novel concept promises nearly doubling the conversion efficiency of conventional coal-fired processes and offering near- zero emissions The improved efficiency would mean that nearly half as much coal is mined and transported to the power plant, and half the greenhouse gases and other pollutants such as sulfur, mercury and dioxins are produced It also offers several crucial distinctions from conventional coal-burning processes Since the process does not involve the combustion of coal in air, it does not involve nitrogen and hence generates practically no NOx In this process, the oxygen necessary to oxidize coal is supplied through an ion selective ceramic membrane electrolyte The resultant product stream primarily consists of CO2 and, hence, it is easier and cheaper to capture compared to waste streams from conventional combustion processes
