20110158100 | EARLY TRAFFIC REGULATION TECHNIQUES TO PROTECT AGAINST NETWORK FLOODING - Methods and apparatus for providing an Anti-Flooding Flow-Control (AFFC) mechanism suitable for use in defending against flooding network Denial-of-Service (N-DoS) attacks is described. Features of the AFFC mechanism include (1) traffic baseline generation, (2) dynamic buffer management, (3) packet scheduling, and (4) optional early traffic regulation. Baseline statistics on the flow rates for flows of data corresponding to different classes of packets are generated. When a router senses congestion, it activates the AFFC mechanism of the present invention. Traffic flows are classified. Elastic traffic is examined to determine if it is responsive to flow control signals. Flows of non-responsive elastic traffic is dropped. The remaining flows are compared to corresponding class baseline flow rates. Flows exceeding the baseline flow rates are subject to forced flow rate reductions, e.g., dropping of packets. | 06-30-2011 |

20090281617 | Sleeves for Positioning a Stent on a Delivery Balloon Catheter System - The present invention provides one or more sleeves for positioning a stent on a stent delivery system, such as a balloon catheter. The sleeve wraps around the catheter. One or two sleeves are positioned adjacent to one or both ends of the stent without overlapping with the stent. One end of the sleeve may be attached to the catheter or the balloon. The outer diameter of the end of the sleeve adjacent to the stent may be no greater than the outer diameter of the unexpanded stent. As a result, the profile of the stent delivery system is not increased by the sleeves of the present invention. If the stent dislodges during delivery to the target site, the stent can come to rest on the wall of the sleeve. Because the sleeves are positioned adjacent to the stent without overlapping with the stent, the stent is able to expand without being restrained by the sleeves. In addition, except for the stent, no other component of the stent delivery system, including the sleeves, comes into contact with the vessel wall when the balloon is expanded. This minimizes damages caused by the stent delivery system to the vessel. | 11-12-2009 |

20130258731 | POWER SUPPLY CONTROL METHOD FOR CONSTANT CURRENT CONSTANT POWER CONTROL - A digital power supply and power supply controller are presented, including a voltage control loop and a current control loop, with a controller for pulse width modulating a switching power supply according to a voltage control loop duty cycle output or a current control loop duty cycle output, in which the controller selectively presets the voltage control loop duty cycle output to a predetermined value before switching from current loop control to voltage loop control and/or inhibits increase in a voltage loop integrator value during current loop control to mitigate voltage overshoot. | 10-03-2013 |
