| 20080315568 | Crash Sensor - A crash sensor comprising a support arrangement for supporting opposed ends of a yieldable element directly on one of an outer skin of a vehicle and a component adjacent to the outer skin with the yieldable element substantially parallel with the outer skin of the vehicle. A sensor arrangement in the form of resistors mounted on the yieldable element to generate a signal in response to deformation or bending of the yieldable element. A stiffness and a mass of the yieldable element is selected to achieve such that a period for a complete oscillation of the element at its resonance frequency is of at least 2 milliseconds. | 12-25-2008 |

| 20090126549 | BAND SAW AND METHOD OF SPATIALLY POSITIONING A BAND SAW BLADE - A band saw, a band saw assembly, and a method of spatially positioning a band saw blade are suggested. The band saw comprises a band saw blade against which a sawing material is adapted to be guided in a feed direction. A guide for the band saw blade has at least one magnet exerting a force on the band saw blade determining the spatial position thereof. The at least one magnet is adjustable in its force effect and the force is directed transversely to the feed direction. The guide, as viewed in the feed direction of the sawing material, has a front magnet and a rear magnet, the magnets facing a front area and a rear area, respectively, of the band saw blade. A method of spatially positioning a band saw blade is executed while a sawing material is guided against the band saw blade in a feed direction. A magnet force is exerted on the band saw blade. The magnet force, and thereby the position of the band saw blade is adjusted transversely to the feed direction. The magnet force, as viewed in the feed direction of the sawing material, is exerted on a front area and on a rear area of the band saw blade. | 05-21-2009 |

| 20100099163 | SEPARATION MATRIX FOR VIRAL PURIFICATION - The present invention relates to a method of preparing a separation matrix comprising at least one insoluble carrier to which sulphate ligands have been attached via extenders, which method comprises coupling, in a first step, of the sulphate ligands to the extenders and, in a subsequent step, attaching the extenders to an insoluble carrier. The invention also relates to a separation matrix comprised of at least one insoluble carrier to which sulphate ligands have been attached via extenders. Advantageously, no sulphate ligands are directly attached to the insoluble carrier. The extenders may be natural polymers, such as dextran, and the insoluble carrier may be made from natural polymers, such as agarose, or synthetic polymers. The invention also relates to a method of purifying virus, such as influenza virus, using a separation matrix according to the invention. | 04-22-2010 |
