  • Method of polynucleotide synthesis using modified support
    Patent number: 7585970
    Abstract: A method for synthesizing a polynucleotide is disclosed. The method comprises providing a functionalized support comprising a triaryl methyl linker bound to the solid support through a substitution on one of the aryl groups, a nucleotide chain bound to the central methyl carbon of the triaryl methyl group and a nucleoside with a reactive site hydroxyl. The method further provides contacting that functionalized support with a precursor having a hydroxyl protecting group and a phosphorous derivative reactive group to produce internucleotide linkage. The resulting compound is then treated to both remove the hydroxyl protecting group on the precursor, and to oxidize the internucleotide bond.

  • Systems and methods for synchronizing time across networks
    Patent number: 7573914
    Abstract: By equipping receiving devices in a network with synchronizable clocks it is possible to periodically send an “impulse” signal that is received by all of the clocks at the same (or relatively the same) instant of time. The accuracy of the impulse clock need not be high, only that its signal reach all the clocks approximately at the same time. In one embodiment, a transmitting device, upon receipt of the synchronizing impulse signal, sends a packet of data bearing the sending device's epoch time-stamp to a receiving device. The data packet makes its way through the network element to the receiving device and the time-stamp is used by the receiving device to calculate the difference between the epoch time of the receiver and the epoch time of the sender. Effectively, this procedure removes the unknown network element transit times from the equation and allows the devices to operate in a synchronized manner.
