  • Patent number: 8719316
    Abstract: The reliable writing of data to multiple data stores using a write agent. The overall write operation is managed by a write manager that is communicatively coupled to the write agent and to a certain data store. Upon determined that multiple data stores are to be written to, the write manager first instructs the write agent to perform a delay write to other data store(s). The delay write means that the write agents waits a delay time before performing the write unless instructed in the meantime to more immediately perform the write, and if a delay passes, does not perform the write without first checking that the write has been made to the certain data store. After instructing the write agent to delay write, the write manager attempts to write to the certain data store. Upon successfully writing to the certain data store, the write manager may instruct the write agent to proceed immediately.

  • Patent number: 8719170
    Abstract: A method and system for transferring licenses between electronic devices supporting licensable features. Specifically, in a method a request is generated for transferring a license between first and second electronic devices. The request includes first information unique to the first electronic device, second information unique to the second electronic device. The request is sent to a license distributor to generates a master key. The master key includes a removal key including the first information and an add key including the second information. The removal key is used to remove the license from the first electronic device when the first information matches official versions of the first information. The add key is revealed from the master key when the license is successfully removed. The add key is used to add the license to the second electronic device when the second information matches official versions of the second information.

  • Patent number: 8716546
    Abstract: A two step process for the destruction of a precursor material using a steam plasma in a three zone reactor wherein the precursor material is hydrolyzed as a first step in the high temperature zone of the reactor, followed by a second step of medium temperature oxidation of the reactant stream in the combustion zone of the reactor where combustion oxygen or air is injected and immediate quenching of the resulting gas stream to avoid the formation of unwanted by-products. A related apparatus includes a non transferred direct current steam plasma torch, an externally cooled three zone steam plasma reactor means for introducing the precursor material into the plasma plume of the plasma torch, means for introducing the combustion air or oxygen into the combustion zone, means for exiting the reactant mixture from the reactor and means for quenching the reactant mixture located at the exit end of the reactor.

  • Patent number: 8715160
    Abstract: The present disclosure is directed to an external cardiac basal annuloplasty system (ECBAS or BACE-System: basal annuloplasty of the cardia externally) and methods for treatment of regurgitation of mitral and tricuspid valves. The BACE-System provides the ability to correct leakage of regurgitation of the valves with or without the use of cardiopulmonary bypass, particularly when the condition is related to dilation of the base of the heart. This ECBAS invention can be applied to the base of the heart epicardially, either to prevent further dilation or to actively reduce the size of the base of the heart.
