Abstract: The present invention provides a system, method and data format wherein a redundant sync byte or group of sync bytes is provided in a data sector at a distance sufficient to isolate the redundant sync byte from the primary sync byte in the event of multiple byte defects. In a first embodiment, a redundant sync byte, or group of sync bytes, is provided in the AGC field preceding the primary sync region. Upon failure to detect the primary sync byte, an attempt is made on a subsequent revolution to read the secondary sync byte, either by holding the AGC gain prior to reaching the data block, or initiating an “early read” just prior to reaching the data block. In a second embodiment of the invention, the redundant sync byte is provided within the data field subsequent to the primary sync region. On failing to detect the primary sync byte, the secondary sync byte can be read immediately or can be postponed until a subsequent revolution.

Abstract: The present invention is drawn to the use of artificially attenuated Coxsackievirus B3 cardiotropic virus vectors as efficient gene transfer vectors to deliver immunomodulatory proteins and/or antigenic epitopes in transient infections to aid in preventing, ameliorating, and/or ablating infectious viral heart disease and reducing, or ablating entirely, heart transplant rejection. Additionally, other organs or tissues may be targeted with specific picornaviruses. An attenuated CVB3 viral vector able to express a cytokine is provided.

Abstract: A method and apparatus for piercing a pair of aligned holes through both sides of a tube combined with the process of hydroforming the tube to final shape. After the tube is expanded and internally pressurized between upper and lower dies, a punch is driven forcefully through a cross passage in the die and through both walls of the tube, one after the other. The end of the punch is bored out sufficiently to leave a sharp edge that cuts a first slug, and the first slug is wedged into the end of the punch. The opposed wall of the tube is backed by a female die button with a cylindrical cutting edge concentric to, and equal in diameter to, the end of the punch. The end of the punch enters the die button to cleanly shear out a second hole, pushing a stack of two slugs into the die button. A pressure feed orifice properly located enters the still pressurized tube at this point, feeding positive pressure to the punch bore to blow the slugs off and out of the die button.
