  • Patent number: 7458499
    Abstract: An apparatus and method for filling a ball grid array template is disclosed. The apparatus comprises a normally horizontal base plate with the ball grid array template being mounted onto the base plate at one end. A solder ball supply bin is slidably mounted over the surface of the base plate. The bin is enclosed on three vertical sides, while the fourth vertical side proximate the ball grid array template is a pivotable ball gate. At rest, the bin is located at an end of the base plate opposite to the template. When the base is tilted, the bin slides from its rest location to the other end of the base plate, so that it is positioned over the template, thereby allowing the solder balls to fill the locating holes of the template. The base is then rotated so that it tilts the opposite way, allowing the bin to return to its rest position. As the bin returns to its rest position, the ball gate sweeps any excess balls on the surface of the template back into the bin.

  • Publication number: 20060217445
    Abstract: Provided herein are methods for reducing oxidative DNA damage in a subject, by administering to the subject astaxanthin, for instance a natural, astaxanthin-enriched extract from Haematococcus pluvialis. It is shown that doses as low as 2 mg/day, given orally to a human subject for a period of four weeks, is sufficient to reduced measurable endogenous oxidative DNA damage by about 40%.

  • Patent number: 6909786
    Abstract: In a secure communication employing keys which require updating, all parties to the communication update their keys according to a clock at a suitable agreed-upon interval, and the keys are updated once each interval via a one-way function. The key to be used for a communication is the one that is current when the communication is established. In order to address clock-slip and slight timing differences across a communication channel, each party to a paired communication send a current interval index of their key to the other party. The remote index, i.e., the interval index which is remote to the receiving party, is compared against the local interval index, and the latter of the two interval indexes is used as the basis for generating the key. The party with the earlier index must therefore update the key iteratively until its index is concurrent with the later index. In addition, a public-key, private-key pair is generated for the purpose of supporting key updating.
