  • Publication number: 20050113705
    Abstract: Disclosed is a “tracker system” that includes implanted electrical leads which are part of an implanted cardiotracker plus external equipment that includes external alarm means and a physician's programmer. The tracker system is designed to monitor the degradation of a patient's cardiovascular condition from one or more causes. These causes include the rejection of a transplanted heart and/or the progression of a stenosis in a coronary artery. As one or more stenoses in a coronary artery become progressively more narrow thereby causing reduced blood flow to the heart muscle coronary circulation, the tracker system can alert the patient by either or both internal and/or external alarm means to take the appropriate medical action. The physician's programmer can be used to display histograms of key heart signal parameters that are indicative of the patient's cardiovascular condition.

  • Publication number: 20050085848
    Abstract: Disclosed is a constraining mechanism that enhances the strength of a medical device, while also preventing over expansion of the device, during a procedure. The medical device includes a plurality of biased struts to which a constraining mechanism is coupled. The constraining mechanism includes a spine, which couples to one of the plurality of struts, and one or more branches extending from the spine. The branches have a curvature enabling the branches to substantially surround the plurality of struts while at the same time avoiding contact with the wall of the blood vessel of the patient when the medical device is deployed.

  • Publication number: 20050071837
    Abstract: A system, method and article of manufacture are provided to perform an automated concurrent licensed internal code (LIC) update and an automated nonconcurrent LIC update on a storage controller. The automated concurrent LIC update is performed on a storage controller by sequentially updating each cluster while maintaining operation of the storage controller. The automated concurrent LIC update allows multiple hosts to continue to access data via the storage controller while the system is actively undergoing the LIC update. The automated nonconcurrent LIC update is performed during the time the storage controller in not operating. The automated nonconcurrent LIC update allows service personnel to perform the update in an efficient and timely manner. When the update has completed, the storage controller becomes available to process data and the system is operating at the latest LIC level.

  • Publication number: 20050045793
    Abstract: A brace assembly supports an outlet box that receives an electrical fixture. A first brace member has a first base. A second brace member has a second base and is adjustably received by the first brace member. A first mounting surface extends from the base of the first brace member. The first mounting surface forms a first angle greater than 90 degrees with the first base. A second mounting surface extends from the second base of the second brace member. The second mounting surface forms a second angle greater than 90 degrees with the second base. The angled mounting surfaces provide a compression fit between the brace assembly and supports to which the first and second brace members are secured.

  • Publication number: 20050039601
    Abstract: An air filter assembly for removing particulate matter from an incoming dirty air stream. The assembly includes a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and a non-cylindrical shaped elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. A plurality of non-cylindrical filter elements are preferred. The non-cylindrical filter elements provide a decreased incoming air stream velocity when compared to conventional cylindrical filter elements having the same surface area. Alternately, the non-cylindrical filter elements allow an increase in the volume of incoming air when compared to conventional cylindrical filter elements having the same surface area.

  • Publication number: 20050025883
    Abstract: This invention relates to a brake component having a coating material applied thereto adapted for use in a vehicle brake assembly, method for producing such a brake component, and a vehicle brake assembly including such a brake component. The brake component is selected from the group consisting of brake shoe and a brake rotor. The brake shoe includes a friction lining having an outer surface having surface irregularities and the brake rotor including an inner cylindrical braking surface having surface irregularities. The surfaces of the brake components are disposed adjacent one another and adapted to frictionally engage one another when the brake assembly is actuated. The brake component surface having the surface irregularities prevents complete contact between the adjacent surfaces of the brake components prior to any burnishing or other contact or wear of components.

  • Publication number: 20040034307
    Abstract: This invention describes a method for increasing the speed of the parabolic marching method by about a factor of 256. This increase in speed can be used to accomplish a number of important objectives. Firstly, the speed can be used to collect data to form true 3-D images or 3-D assembled from 2-D slices. Speed allows larger images to be made. Secondly, the frequency of operation can be increased to 5 MHz to match the operating frequency of reflection tomography. This allow the improved imaging of speed of sound which in turn is used to correct errors in focusing delays in reflection tomography imaging. This allows reflection tomography to reach or closely approach its theoretical spatial resolution of ½ to ¾ wave lengths. A third benefit of increasing the operating frequency of inverse scattering to 5 MHz is the improved out of topographic plane spatial resolution. This improves the ability to detect small lesions.
