An embodiment of the invention provides a method and apparatus for registering two medical images with one another. A first medical image including a representation of a biological organ of a subject or for a population is obtained and the surface of the organ is identified in the first medical image. The identified surface is then used to construct a 3D geometric surface model of the organ. The geometric model is used to derive a motion model that incorporates information on the physical material properties of the organ and external forces that cause the organ to move and deform. A second medical image including a representation of the organ of the subject (or another subject, in the case that the first medical image is an atlas image) is obtained and an alignment is determined between a first surface normal vector field for the organ surface, derived from the geometric model, and a second surface normal vector field for the organ surface, derived by filtering the second medical image. The alignment accommodates deformation of the geometric model in accordance with the motion predicted by the motion model. The first and second medical images can then be registered with one another based on said determined model-to-image vector alignment (MIVA).

A file system that permits predictable accesses to file data stored on devices that may have a variable access latency dependent on the physical location of the file on the physical storage device. A variety of features that guarantee timely, real-time response to I / O file system requests that specify deadlines or other alternative required quality-of-service parameters. The file system addresses needs to accommodate the file systems of storage devices such as disks that have an access time dependant on the physical location of the data within the storage device. A two-phase, deadline-driven scheduler considers the impact of disk seek time on overall response times. Non real-time file operations may be preempted. Files may be preallocated to help avoid access delay caused by non-contiguity. Disk buffers may also be preallocated to improve real-time file system performance.

A method and apparatus for treating ship ballast water before it is discharged into coastal waters. The ballast water may contain a generalized and diverse species population of harmful non-indigenous microorganisms. Before discharge, the ballast water is oxygenated and deoxygenated to reduce the populations of anaerobic and aerobic microorganisms, respectively. If anaerobic microorganisms are of no concern, the oxygenation step can be eliminated. Also, a method and apparatus for treating large volumes of any water, to reduce the population of a wide spectrum of diverse species of microorganisms wherein the water is deoxygenated, and then held in a sealed space for a period of time until the aerobic population has been reduced.

Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector. In order to determine if continuity has been established between the optical field fibers and respective optical fiber stubs, a method is also provided that introduces light into at least one of each pair of optical field fibers and optical fiber stubs and that only secures the position of each optical field fiber relative to the respective optical fiber stub once the glow associated with each pair of optical field fibers and optical fiber stubs dissipates, which dissipation indicates the establishment of continuity. An improved multifiber connector and installation tool are also provided to facilitate the establishment and validation of the continuity of optical field fibers and optical fiber stubs in order to reduce the time and cost required to connectorize optical field fibers in the field.

The present invention relates to scaffolds which can be used as medical devices for guided tissue regeneration and repair, in particular the invention is directed to a scaffold comprising fibers having a mean fiber diameter of between from about 1.2 to 4.0 microns, wherein the fibers comprise a glycolide. The invention further relates to the use of the scaffolds for the selective capture of cell populations for a cell source material.

A system and method for highly selective intrusion detection using a sparse array of ultra wideband (UWB) radars. Two or more UWB radars are arranged in a sparse array around an area to be protected. Each UWB radar transmits ultra wideband pulses that illuminate the area to be protected. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the area to be protected. This image is used to detect motion in a highly selective manner and to track moving objects within the protected area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.
