  • GAS TURBINE ENGINE WITH HEAT PIPE SYSTEM
    Publication number: 20180209342
    Abstract: A gas turbine engine includes a rotor section proximate to a combustor section, where the rotor section is subject to bowing effects due to thermal differences and heat transfer at engine shutdown. The gas turbine engine also includes a heat pipe system. The heat pipe system includes one or more heat pipes installed between an upper portion of the rotor section and a lower portion of the rotor section. The heat pipe system is operable to accept heat at a hot side of the heat pipe system at the upper portion, flow heat from the hot side to a cold side of the heat pipe system, and reject heat from the cold side of the heat pipe system at the lower portion to reduce a thermal differential between the upper portion and the lower portion at engine shutdown.

  • TEAR DUCT RESISTANCE MEASURING SYSTEM
    Publication number: 20170196448
    Abstract: A system for measuring the flow properties of a tear duct, to ascertain its flow resistance, includes a syringe communicating with a cannula to supply liquid to a punctum of an eye, the cannula having a tip to seal to the punctum. A motor is arranged to actuate the syringe. A pressure sensor monitors the pressure of the liquid supplied to the punctum. A monitoring circuit provides an indication of the flow resistance. A feedback circuit controls the motor in accordance with the measured pressure, to maintain a preset liquid pressure, or to ensure that the liquid pressure does not exceed a preset threshold. The system may prevent flow through the other punctum of the eye. If the flow rate of the liquid supplied to the punctum is also monitored, the monitoring circuit is arranged to determine the flow resistance from the pressure and the flow rate.

  • Security system and method with multistate alert user interface
    Patent number: 9552135
    Abstract: A security system, system user interface, and method for displaying status information from security devices in a networked security system using a multistate alert user interface. The security system supports different features in icons associated with the security devices, displayed on a graphical user interface. This provides operators with the ability to display status information from security devices, such as alert information comprising one or more alerts, by displaying the icons on a topology map of the graphical user interface. In this way, the operator can determine at a glance the number and type of alert information from the topology map without the need to perform additional selection and navigation steps within the graphical user interface.

  • Multi-electrode energy delivery device and method of using the same
    Patent number: 9339328
    Abstract: An energy delivery device for treating a patient includes a probe body and a plurality of elongate electrode elements that extend radially away from the probe body when deployed into tissue of the patient. The electrode elements are adapted to receive electrical treatment energy such as irreversible electroporation (IRE) pulses from an energy source. In one embodiment, each electrode element has a longitudinally varying electrical resistance at the electrode-tissue interface along the electrode so as to provide a uniform electric field along the length of the electrode. The uniform electric field allows a more uniform ablation of tissue within a treatment zone.

  • Advanced cooling for power module switches
    Patent number: 9220184
    Abstract: A system includes an electronic device, a heat spreader with a vapor chamber attached to a bottom end of the electronic device, so that heat flows from the electronic device to the heat spreader, and a heat sink with microchannels running through it attached to a bottom end of the heat spreader, so that heat from the heat spreader flows through the heat sink and to an ambient. A method for cooling a device includes transferring heat generated by a device through a conductivity layer, spreading the heat through a heat spreader, transferring the heat from the heat spreader to a heat sink that contains microchannels, and releasing the heat from the heat sink into an ambient.
