20090265458 | DYNAMIC SERVER FLOW CONTROL IN A HYBRID PEER-TO-PEER NETWORK - Technologies are described herein for providing dynamic flow control of requests to a server in a hybrid peer-to-peer network. The server collects a number of metrics related to its current stability and the throughput of requests from peer-to-peer devices. These metrics, along with associated trend data, are used by the server to calculate a current stability rating and a current throughput rating. The server then imposes flow control on a proportional number of the peer-to-peer devices based upon the current ratings. This operation is run periodically, with ratings re-calculated from current metrics, and new flow control measures imposed in each cycle. | 10-22-2009 |

20090115415 | SYSTEM AND METHOD FOR USE OF NANOPARTICLES IN IMAGING AND TEMPERATURE MEASUREMENT - This invention provides a system and method that improves the sensitivity and localization capabilities of Magnetic Particle Imaging (MPI) by using combinations of time-varying and static magnetic fields. Combinations of magnetic fields can be used to distribute the signals coming from the magnetic particles among the harmonics and other frequencies in specific ways to improve sensitivity and to provide localization information to speed up or improve the signal-to-noise ratio (SNR) of imaging and/or eliminate the need for saturation fields currently used in MPI. In various embodiments, coils can be provided to extend the sub-saturation region in which nanoparticles reside; to provide a static field offset to bring nanoparticles nearer to saturation; to introduce even and odd harmonics that can be observed; and/or to introduce combinations of frequencies for more-defined observation of signals from nanoparticles. Further embodiments provide for reading of the signal produced by cyclically saturated magnetic nanoparticles in a sample so as to provide a measurement of the temperature of those nanoparticles. The spectral distribution of the signal generated provides estimates of the temperature of the nanoparticles. Related factors may also be estimated—binding energies of the nanoparticles, phase changes, bound fraction of the particles or stiffness of the materials in which the nanoparticles are imbedded. | 05-07-2009 |

20090178184 | Sport helmet - A helmet padding consists of sets of one or more tubes, with each set of tubes located at a crucial area of the shell of the helmet. An armature and tubes are connected together and mounted within the inner shell of the helmet. The helmet uses a new fastener to fasten a cage to the helmet shell allowing sides of the cage to be mounted directly against the shell, reducing the width of the shell on each side. A ball is attached to a portion of a bar of the cage to act as a limit stop precluding movements of the cage with respect to the helmet. A chin bar is fastened to the helmet at two points on each side of the shell. The shell is molded with recessed portions designed to receive the two branches of the chin bar on each side where they will be fastened to the shell so that the outer surfaces of the chin guard are flush with the shell at the locations of attachment to provide a smooth transition and reduce weight. An adjustment device to adjust the fit of the helmet to the user includes a star wheel on each side of the helmet attached to an arcuate flexible strip extending rearwardly around the occipital area of the skull. A sliding mechanism attached to the strip allows the strip to be moved forward and backward to allow it to be tightened or loosened, respectively, with respect to the player's head. A ratcheting lateral adjustment device is also disclosed. | 07-16-2009 |
20090178185 | Face and eye guard device - The eye guard, while complying with ASTM F803-03, has been ergonometrically designed to comfortably fit on the user's face, and to provide openings for the eyes allowing clear vision while at the same time protecting the eyes from impacts from a lacrosse ball. The eye openings are completely open and have dimensions intended to preclude a lacrosse ball from passing therethrough. The upper edges of the eye openings are displaced rearwardly with respect to the lower edges a sufficient distance to preclude a lacrosse ball from striking the two edges simultaneously in a direction that could possibly cause an eye impact. That displacement is specifically devised to cause a lacrosse ball striking one or the other of the edges to be deflected away from the eyes of the player. The upper edge of the eye openings also defines the lower edge of a visor surface. That visor surface transitions from the openings to the rearward edge of the eye guard where it engages the face of the user above the eyes. Below the eye openings, additional openings are provided that are shaped to be aesthetically pleasing and also create a nose engaging portion designed to surround upper portions of the nose. Temples are preferably molded of a flexible material and may include a unique attachment device for an elastic band used to hold the eye guard on the head of the user. | 07-16-2009 |
20110072549 | Eye protector - Embodiments of an eye protector are made of a molded plastic part connected with a metal part. The plastic part consists of a generally C-shaped configuration with an elongated portion overlying the eyebrows and arcuate fingers designed to overlie the wearer's cheekbones. The metallic part includes an arcuate portion staggered significantly forwardly with respect to the plastic part. The horizontal stagger virtually precludes a ball from impacting on both the plastic part and the metallic part simultaneously, and the thin profile of the metallic part causes deflection of a ball rather than rebound. Embodiments also include a downwardly depending inverted V-shaped portion that protects the wearer's face below the eyes. | 03-31-2011 |
20130312162 | SPORT HELMET - The helmet uses a new fastener to fasten a cage to the helmet shell allowing sides of the cage to be mounted directly against the shell, reducing the width of the shell on each side.
