  • Patent number: 8491647
    Abstract: A medical prosthesis having a low profile for delivery into a body lumen is disclosed. The stent includes a plurality of wire strands woven to form a plurality of joints at the intersections, some of which are helically wrapped. The helically wrapped joints may be offset form the joints of a second plurality of wire strands concentric to the first. Alternatively, the helically wrapped joints can doubled forming box nodes.

  • Patent number: 7172617
    Abstract: The present invention relates to a system for delivering a medical prosthesis into a body lumen. A preferred embodiment of the invention utilizes a catheter having a stent mounted at the distal end that is released into the body lumen by movement of an outer sheath covering the stent in the proximal direction. The stent expands to conform to the inner wall of the lumen and the catheter is withdrawn.

  • Patent number: 6100835
    Abstract: A multi-symbol analysis process compensates for inter-symbol interference in communication signals. The multi-symbol analysis process determines a digital value for a symbol represented by a selected symbol period by correlating a digitized sample within the selected symbol period with a sum of weighted signal components. The sum of weighted signal components includes contributions from the selected symbol period and symbols from a number of other symbol periods that occur before and after the selected symbol period. The multi-symbol analysis process allows more extensive digital filtering, which reduces the bandwidth required to achieve the signal to noise ratio necessary to determine correctly a digital symbol represented by an analog signal. As a result, the multi-symbol analysis process can markedly increase the capacity of communications channels, including satellite communication channels.

  • Patent number: 5952620
    Abstract: A loudspeaker including a generally spherical cabinet and at least one speaker driver contained in the cabinet and dividing the cabinet into a major sound chamber and a minor sound chamber. The cabinet has at least two sound propagation ports communicating with the major sound chamber and at least two sound propagation ports communicating with the minor sound chamber. The spherical cabinet of the loudspeaker provides an omni-directional radiation pattern. According to one possible embodiment, the at least one speaker driver comprises two speaker drivers facing each other and connected out of electronic phase so as to operate as a single push-pull unit. The loudspeaker, therefore, utilizes the rear sound waves created by its speaker drivers. One of the speaker drivers is substantially contained in the minor sound chamber and the other of the speaker drivers is substantially contained in the major sound chamber.
