Abstract: A method and system for suspending log-based updating of a database in a manner that permits its resumption without restore, to permit efficient alternation between a log-based update mode and a database access mode. Unplayed log records are protected, as re versions of database pages at a time when the log-based update was suspended. This permits log-based updating to resume where it left off. In order to ensure consistent data for access, a roll-back procedure creates consistent data pagers that are used for access, and discarded when log-based update resumes.

Abstract: When audio dubbing is implemented, error correction is performed for each ECC block. Therefore, even when one byte of data in an ECC block is rewritten, the whole ECC block to which the byte belongs needs to be read and rewritten. When audio dubbing data is scattered in ECC blocks, almost all ECC blocks, or all the data needs be rewritten in order to record audio dubbing data. By constructing ECC blocks including audio dubbing data so as not to contain original data, it is no longer necessary to read and rewrite unnecessary original data when audio dubbing data is overwritten.

Abstract: A solder composition and associated method of formation. The solder composition comprises a substantially lead-free alloy that includes tin (Sn), silver (Ag), and copper. The tin has a weight percent concentration in the alloy of at least about 90 %. The silver has a weight percent concentration X in the alloy. X is sufficiently small that formation of Ag3Sn plates (57, 58) is substantially suppressed when the alloy in a liquefied state is being solidified by being cooled to a lower temperature at which the solid Sn phase is nucleated. This lower temperature corresponds to an undercooling .delta.T relative to the eutectic melting temperature of the alloy. Alternatively, X may be about 4.0 % or less, wherein the liquefied alloy is cooled at a cooling rate that is high enough to substantially suppress Ag3Sn plate (57, 58) formation in the alloy. The copper has a weight percent concentration in the alloy not exceeding about 1.5 %.

Title: Anastomosis wire ring device
Inventor: TANAKA DON A
IPC: A61B17/115
Filed: 2004-09-30
Granted: 2012-06-19
Abstract: An anastomotic ring device for forming a hollow rivet (ring) attachment between tissue lumens facilitates laparoscopic or endoscopic implantation by including features that facilitate actuation from a stressed, generally cylindrical shape. Economical manufacturer is achieved by weaving open ended strands into a generally cylindrical stent shape that is imparted with a Shape Memory Effect (SME) to actuate to a hollow rivet (ring) shape. Alternatively or in addition to SME inherent in the woven strands, an actuating force may be received from a helical spring element incorporated into the ring. Self- actuating ring devices are enhanced by forming woven strands into petals that diverge from opposing petals such that the strands encounter less friction when actuating. Each of these features alone or in combination enhance clinical use of anastomotic ring devices, such as a bariatric gastric bypass procedure.

Granted: 2008-12-30
Abstract: A spring clutch has an arbor, a spring, and a sleeve. The spring at least partially surrounds the arbor and has a first portion coupled to the arbor to confine relative rotation of the first portion and arbor about an axis. The sleeve at least partially surrounds the spring and cooperates with the spring.  The cooperation is sufficient so that an initial relative rotation between the arbor and sleeve in a first direction about the axis tends to uncoil the spring and bias the spring into firmer engagement with the sleeve. The cooperation is sufficient such that relative rotation in an opposite direction tends not to uncoil the spring and maintains the clutch in a disengaged condition.
