Title: Congestion Prevention Apparatus and Method of Router
Inventor: SHIN YEONG SU
IPC: H04L47/32
Filed: 2001-11-30
Abstract: PURPOSE: An apparatus and method for preventing congestion of a router is provided to enhance the performance of a network by dynamically applying an RED(Random Early Detection)/WRED(Weighted Random Early Detection) according to a protocol type of a packet to be inputted to a buffer. CONSTITUTION: When an IP(Internet Protocol) packet to be transmitted is received(S10), a protocol field included in a header of the IP packet is analyzed to judge whether the protocol of the IP packet is a TCP(Transmission Control Protocol)(S12). If the protocol of the IP packet is the TCP protocol, a flag is set to '1', and then the flag set by '1' is added in the IP packet and applied to an RED/WRED application determining unit(S14). The RED/WRED application determining unit judges whether to apply RED/WRED to the IP packet(S18). If the RED/WRED application determining unit judges to apply RED/WRED, it applies RED/WRED to the IP packet to prevent the occurrence of an inclusive synchronization(S20). If the RED/WRED application determining unit judges not to apply RED/WRED, it changes a current average size of a buffer(S22) and inputs the IP packet to the buffer(S24).

Title: Antitachycardial pacing
IPC: A61N1/39
Filed: 2000-01-14
Abstract: Protocols for antitachycardial pacing including biphasic stimulation administered at, or just above, the diastolic depolarization threshold potential; biphasic or conventional stimulation initiated at, or just above, the diastolic depolarization threshold potential, reduced, upon capture, to below threshold; and biphasic or conventional stimulation administered at a level set just below the diastolic depolarization threshold potential. These protocols result in reliable cardiac capture with a lower stimulation level, thereby causing less damage to the heart, extending battery life, causing less pain to the patient and having greater therapeutic effectiveness. In those protocols using biphasic cardiac pacing, a first and second stimulation phase is administered. The first stimulation phase has a predefined polarity, amplitude and duration. The second stimulation phase also has a predefined polarity, amplitude and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is first applied and followed by cathodal stimulation. In this fashion, pulse conduction through the cardiac muscle is improved together with the increase in contractility.

The preparation method of particulate composition using polymer resin having self-emulsification characteristics comprises the steps of heating a polar solvent; adding polymer resin having self-emulsification characteristics and functional material to the heated polar solvent; emulsifying the mixture by agitating the mixture in the heating state; and recovering powder by cooling, washing and drying the emulsified mixed solution. The preparation method of dyed particulate composition using polymer resin having self-emulsification characteristics comprises the steps of heating a polar solvent; adding polymer resin having self-emulsification characteristics and functional material to the heated polar solvent; emulsifying the mixture by agitating the mixture in the heating state; agitating the dyestuff added mixed solution by adding dyestuff to the emulsified mixed solution; and recovering powder by cooling, washing and drying the dyed emulsified mixed solution. The preparation method of colored particulate composition using polymer resin having self-emulsification characteristics comprises the steps of heating a polar solvent selectively including stabilizer; agitating the colorant added mixed solution in the heating state by adding the polymer resin having self-emulsification characteristics uniformly mixed with colorant to the heated polar solvent; and recovering powder by cooling, washing and drying the dyed emulsified mixed solution.
