20090260778 | LOW PROFILE HEAT SINK FOR SEMICONDUCTOR DEVICES - A heat sink for cooling a heat-generating device includes a base and a cooling section coupled thereto for cooling the device. The cooling section includes a plurality of flow tubes, each flow tube having an inlet, an outlet, and a bounding wall that defines a closed fluid flow path from the inlet to the outlet. Each of the flow tubes includes a central axis that is substantially parallel to a reference plane of the heat-generating device. The flow tubes may be arranged in a layered stack and include a bounding wall that has a thickness that decreases with increasing distance in the layered stack. The flow tubes may also include a cross-sectional area that decreases with increasing distance in the layered stack. Furthermore, the bounding wall of the flow tubes may have a non-planar configuration in a direction generally parallel to the central axis. | 10-22-2009 |

20130287551 | SEPARABLE SEAL ASSEMBLY FOR A GAS TURBINE ENGINE - A seal assembly for sealing a rotatable shaft in a gas turbine engine, wherein the shaft includes sections of greater shaft diameter located both forward and aft of the seal shaft coupling point is provided. The seal assembly includes a first semi-annular segment with a first end, a second end, and a plurality of seal teeth, where the first and second ends each include an overlap joint. The seal assembly also includes a second semi-annular segment with a first end, a second end, and a plurality of seal teeth, where the first and second ends each include an overlap joint. The first end of the second segment is coupled to the first end of the first segment, and the second end of the second segment is coupled to the second end of the first segment. | 10-31-2013 |

20100120007 | Fluid Percussion System and Method for Modeling Penetrating Brain Injury - A fluid percussion system for modeling penetrating brain injury includes a fluid percussion device that takes inputs in the form of pressurized gas and electrical signals from a computer and outputs a single hydraulic pulse, or multiple hydraulic pulses in quick succession. The fluid percussion device may include a pneumatic cylinder assembly and a hydraulic cylinder assembly that is actuated by the pneumatic cylinder assembly to produce the hydraulic pulse(s) of pressurized fluid. Each pulse may be used to rapidly inflate and deflate an attached balloon (representing a brain penetrating device). The balloon may be inserted in a test specimen, and the rapid inflation and deflation of the balloon creates a lesion that simulates a penetrating brain injury. A calibration system that employs an optical sensor may be used to determine maximum balloon diameter achieved during rapid inflation. | 05-13-2010 |
