  • Patent number: 11135053
    Abstract: The present application provides an implantation method of an artificial heart valve. The implantation method can include forming an incision in the left chest to expose the ventricle; advancing a guide wire kept away from chordae tendineaes through the atrium into the ventricle; advancing a guide wire catcher into the ventricle from the incision to pull out the distal end of the guide wire from the ventricle; and advancing the artificial heart valve into the ventricle from the distal end of the guide wire with a valve deliverer, and placing the artificial heart valve at a primary valve between the ventricle and the atrium along the guide wire. The artificial heart valve may avoid the chordae tendineaes in the heart system through the guide wire track during implantation.

  • Patent number: 7895500
    Abstract: Systems and methods for generating check node updates in the decoding of low-density parity-check (LDPC) codes use new approximations in order to reduce the complexity of implementing a LDPC decoder, while maintaining accuracy. The new approximations approximate the standard sum-product algorithm (SPA), and can reduce the approximation error of min-sum algorithm (MSA) and have almost the same performance as sum-product algorithm (SPA) under both floating precision operation and fixed-point operation.

  • Publication number: 20040247969
    Abstract: Improved metal-air fuel cell battery systems having metal-fuel realized in the form of metal-fuel tape cartridges and metal-fuel cards, which can be either manually or automatically inserted within the power generation bay of the system. In order to produce a range of output voltages, the metal-fuel tape has a plurality of electrically-isolated metal-fuel tracks and the metal-fuel cards have a plurality of electrically-isolated metal-fuel strips. An output voltage configuration subsystem is provided for configuring the voltages produced by the individual cells to produce a desired output. A subsystem is provided for detecting oxide formation on the metal-fuel tracks and strips so that only metal-fuel that has been oxidized is reduced during recharging operations. A subsystem is also provided for controlling the flow of oxygen into the power generation head in order to control the power output from the system.

  • Patent number: 6794069
    Abstract: Fuel cells (e.g., air-depolarized fuel cells) are stacked, supported and electrically interconnected into a battery structure with a connector block. The anode and cathode elements of each fuel cell are provided with conductive terminating elements (e.g., plug connectors), preferably extending in downward “U” shaped configuration from the upper ends of the anode and cathode elements respectively. The connector block comprises a series of conductive apertures, positioned and sized, to accommodate the conductive terminating elements of the anodes and cathodes therein. When the conductive terminating elements of the anodes and cathodes are slidably engaged with the conductive apertures of the connector block, the connector block mechanical support the anodes and cathode so engaged.
