  • Publication number: 20240345862
    Abstract: Automatic generation of service instance managers includes automatically generating, from a first representation of a service instance manager for an environment, a second representation of the service instance manager. The first representation and second representation are programmed in different technologies. The automatically generating includes obtaining a universal form into which the first representation was transformed via a transformation, and further includes generating the second representation using the universal form and variable information, recovered from the first representation, lost by the transformation of the first representation into the universal form.

  • Publication number: 20150370739
    Abstract: Methods and structure for local reconnect attempts via a Serial Attached Small Computer System Interface (SAS) expander. The system includes a SAS expander, which includes a physical link (PHY) that is able to transmit an OPEN Address Frame (OAF) to a coupled SAS device, and to receive an OPEN_REJECT (RETRY) from the coupled device in response to the OAF. The SAS expander also includes a controller that is able to block transmission of the OPEN_REJECT (RETRY) out of the expander in order to preserve a signaling pathway established for the OAF, and to retransmit the OAF to the coupled device via the PHY.

  • Publication number: 20150346762
    Abstract: Methods and structure for dwell timers in Serial Attached Small Computer System Interface (SAS) devices. An exemplary system includes a SAS end device. The SAS end device includes a physical link (PHY) operable to receive an OPEN Address Frame (OAF) from a coupled SAS device. The SAS end device also includes a controller. The controller is able to determine that the end device is presently unable to service a connection, and to wait a period of time for a dwell timer to expire. The controller is also able to service the connection by sending an OPEN_ACCEPT response if the end device becomes able to service the connection before the dwell timer expires, and to send an OPEN_REJECT (RETRY) response if the end device does not become able to service the connection before the dwell timer expires.

  • Patent number: 8887503
    Abstract: A power plant includes a closed loop, supercritical carbon dioxide system (CLS-CO2 system). The CLS-CO2 system includes a turbine-generator and a high temperature recuperator (HTR) that is arranged to receive expanded carbon dioxide from the turbine-generator. The HTR includes a plurality of heat exchangers that define respective heat exchange areas. At least two of the heat exchangers have different heat exchange areas.

  • Patent number: 8622949
    Abstract: A method of providing a pumping system for assisting a human patient's heart and providing a blood pump to be disposed outside the patient's body is disclosed. The blood pump has an inlet and an outlet. An inlet cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump inlet to provide blood to the blood pump. An outlet perfusion cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump outlet to provide blood to the patient's vascular system. The blood pump includes a control system to control the blood pump. The control system includes at least two control units for redundant control of the blood pump, and each control unit includes a watchdog for monitoring the control unit.

  • Publication number: 20130219088
    Abstract: Processing input/output requests may include: processing one or more input/output (IO) requests in a first IO queue associated with a first device group; detecting a queuing of one or more IO requests in a second IO queue associated with a second device group; pausing the processing one or more input/output (IO) requests in a first IO queue associated with a first device group upon a detection of a queuing of one or more IO requests in a second IO queue associated with a second device group; processing the one or more IO requests in a second IO queue associated with a second device group; and resuming the processing one or more input/output (IO) requests in a first IO queue associated with a first device group upon a completion of the processing the one or more IO requests in a second IO queue associated with a second device group.

  • Patent number: 8453882
    Abstract: An apparatus for rapidly cooling beer flowing from a keg to a tap to be dispensed includes an insulated ice chest containing an open topped swirl pot in which is nested a cooling coil having an inlet connected to a keg and an outlet connected to a tap on a hollow upright structure fixed to the outside of an ice chest lid. A pump is connected to a stand pipe within the coil directing a flow of ice water under pressure to generally tangentially directed nozzles within the coil creating a swirl flow of ice water over the coil turns and overflowing back into the ice chest interior space holding ice to create a circulation therein maximizing the rate of cooling of the dispensed beer to minimize foaming when dispensed from the tap. A CO2 tank is also held in the ice chest interior space, connected to the keg via fluid lines and simplified hook ups to the keg are located on the lid mounted hollow structure.

  • Patent number: 8430154
    Abstract: A heat transfer tube includes a container, a cavity within the container, and a heat transfer medium located within the cavity. The heat transfer medium consists essentially of a solid-gas suspension of a gas and a substantially homogeneous nanoparticle powder located within the cavity. The cavity is in a partial vacuum state. The nanoparticle powder comprises Ca(OH)2, LiH, ZrH2, or Mg(OH)2 in a solid state and is capable of substantially freely emitted and reabsorbing the gas as a function of temperature.
