  • Patent number: 8057175
    Abstract: A method and system for increasing power production of a wind turbine including a rotor, at least one rotor blade coupled to the rotor, at least one sensor, and a controller communicatively coupled to the sensor. A flow parameter of the rotor blade is detected, and operation of the wind turbine is controlled to reduce a flow separation at the rotor blade based at least partially on the flow parameter of the rotor blade.
    Type: Grant

  • Patent number: 7751530
    Abstract: An X-ray tube anode assembly, an X-ray tube assembly and a method for heat management to an X-ray assembly having a movable X-ray target having a target surface. The anode assembly includes a drive member arranged and disposed to provide oscillatory motion to the target assembly and a target surface that is configured to remain at a substantially fixed distance from a cathode assembly during oscillatory motion.

  • Patent number: 7672434
    Abstract: An X-ray tube equipped with a rotating anode cartridge comprising a reinforced sealing system. This sealing system is achieved in three complementary manners. Firstly, when the anode rotates, in order to confine the liquid alloy within the cartridge, the invention provides to equip the two surfaces of a leak-tight joint with grooves thereby obtaining a double sided joint with an improved efficiency. Secondly, the double sided joint makes it possible to obtain, for the vacuum tightness, when the anode shaft is not rotating, two spaces limited by the surface tension of the alloy of liquid metal. The more symmetrical these two spaces, the more the sealing is reinforced. Thirdly, the invention provides to separate the ring from the axis of rotation. This enables a joint centering the two spaces in an automatic and natural manner to be obtained.

  • Patent number: 7245700
    Abstract: A system and method for providing a sealing arrangement in an X-ray tube are provided. The X-ray tube includes a rotating portion having a plurality of ball bearings and a liquid metal within a housing having the ball bearings therein. The rotating portion is configured to rotate an anode. The X-ray tube further includes a sealing portion formed by a liquid metal vacuum interface configured in a radial direction to resist flow of liquid metal from the housing to a vacuum portion.

  • Patent number: 7113568
    Abstract: A rotating anode bearing housing includes an x-ray tube frame (106) that has a vacuum chamber (108). An anode (110) resides within the vacuum chamber (108) and rotates on a shaft (114) via a bearing (117). The bearing (117) is attached to an interior surface (126) of the x-ray tube frame (106). The bearing (117) transfers thermal energy from the shaft (114) to the x-ray tube frame (106).
