  • Publication number: 20190166861
    Abstract: Systems and methods are disclosed for the generation of a treatment compound fluid to inhibit the ripening process of agricultural products, the application of the treatment compound fluid to a confined atmosphere at a location at which the products are stored, and the collection of a sample of the treated atmosphere. In one form, the system includes a treatment compound generator and a sampling subsystem. The treatment compound generator has an exit port fluidly connectable to the confined atmosphere and is configured to generate a treatment compound fluid in-situ. The sampling subsystem includes an inlet port fluidly connected to a pump and a collection chamber. The inlet port is fluidly connectable to the confined atmosphere such that the sampling subsystem can collect a sample of the treated atmosphere through the inlet port and store the sample within the collection chamber.

  • Patent number: 9916243
    Abstract: A method and apparatus for performing a bus lock and a translation lookaside buffer invalidate transaction includes receiving, by a lock master, a lock request from a first processor in a system. The lock master sends a quiesce request to all processors in the system, and upon receipt of the quiesce request from the lock master, all processors cease issuing any new transactions and issue a quiesce granted transaction. Upon receipt of the quiesce granted transactions from all processors, the lock master issues a lock granted message that includes an identifier of the first processor. The first processor performs an atomic transaction sequence and sends a first lock release message to the lock master upon completion of the atomic transaction sequence. The lock master sends a second lock release message to all processors upon receiving the first lock release message from the first processor.

  • Patent number: 9673028
    Abstract: Systems and methods for arc handling in plasma processing operations are disclosed. The method includes providing current with a power supply to a plasma load at a first voltage polarity and energizing an energy storage device so when it is energized, the energy storage device applies a reverse polarity voltage that has a magnitude that is as least as great as the first voltage polarity. When an arc is detected, power is applied from the energy storage device to the plasma load with a reverse polarity voltage that has a polarity that is opposite of the first voltage polarity, the application of the reverse polarity voltage to the plasma load decreases a level of the current that is provided to the plasma load.

  • Publication number: 20170022604
    Abstract: A system and method for single magnetron sputtering are described. One example includes a system having a power supply, a plasma chamber enclosing a substrate, an anode, and a target for depositing a thin film material on the substrate. This example also has a datastore with uncoated anode characterization data and an anode sputtering adjustment system including an anode analysis component to generate a first health value. The first health value is indicative of whether the anode is coated with a dielectric material. This example also has an anode power controller to receive the first health value and provide an anode-energy-control signal to the pulse controller of the pulsed DC power supply to adjust a second anode sputtering energy relative to a first anode sputtering energy to eject at least a portion of the dielectric material from the anode.

  • Patent number: 9459877
    Abstract: An apparatus, computer readable medium, and method of performing nested speculative regions are presented. The method includes responding to entering a speculative region by storing link information to an abort handler and responding to a commit command by removing link information from the abort handler. The method may include storing link information to the abort handler associated with the speculative region. When the speculative region is nested, the method may include storing link information to an abort handler associated with a previous speculative region. Removing link information may include removing link information from the abort handler associated with the corresponding speculative region. The method may include restoring link information to the abort handler associated with a previous speculative region. Responding to an abort command may include running the abort handler associated with the aborted speculative region.

  • Patent number: 9152509
    Abstract: A computing device initiates a transaction, corresponding to an application, which includes operations for accessing data stored in a shared memory and buffering alterations to the data as speculative alterations to the shared memory. The computing device detects a transaction abort scenario corresponding to the transaction and notifies the application regarding the transaction abort scenario. The computing device determines whether to abort the transaction based on instructions received from the application regarding the transaction abort scenario. When the transaction is to be aborted, the computing device restores the transaction to an operation prior to accessing the data stored in the shared memory and buffering alterations to the data as speculative alterations to the shared memory. When the transaction is not to be aborted, the computing device enables the transaction to continue.

  • Patent number: 9129776
    Abstract: This disclosure describes a non-dissipative snubber circuit configured to boost a voltage applied to a load after the load's impedance rises rapidly. The voltage boost can thereby cause more rapid current ramping after a decrease in power delivery to the load which results from the load impedance rise. In particular, the snubber can comprise a combination of a unidirectional switch, a voltage multiplier, and a current limiter. In some cases, these components can be a diode, voltage doubler, and an inductor, respectively.
