  • Patent number: 9375310
    Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.

  • Publication number: 20060013086
    Abstract: The present invention discloses a method for generating a write pulse in an optical disk drives, which comprises the steps of: determining an encoded signal; providing a lookup table that integrates a plurality of various types of parameters used for a write pulse signal in different numbers of cycles for encoding and decoding signals; determining the parameters used for the write pulse signal by checking with the lookup table according to the number of cycle corresponding to the encoded signal; and forming the write pulse signal corresponding to the encoded signal according to the parameters obtained from the lookup table. With this invention, an optical disk burner can produce the write pulse with different waveforms to comply with the duplication requirements for various optical disks.
