Abstract: A method and a system for optimizing the alignment of an optical system, such as a telescope, using a multi-degree-of freedom (DOF) actuator/hexapod and star field images. The method iteratively adjusts the hexapod in all DOFs using the damped least squares (DLS) optimization algorithm and dynamically changes the size of pixel windows to measure ensquared energy (ES) as a closed loop feedback.

Abstract: A system and method for a procedure that can be performed on an appropriate subject. A procedure may be planned, at least in part, prior to performing the procedure. An image may illustrate at least a portion of the planned procedure for confirmation and/or alteration of the planned procedure prior to performing the procedure.

Abstract: A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.

Abstract: The present invention is generally directed to methods for an entity to provide access to Internet websites associated with the entity to customers that currently do not have Internet access. Additional methods are provided for billing an entity associated with a website for access to the website by the entity's customers.

Abstract: A cryopump having a cryopump chamber includes a purge gas valve coupled to the cryopump chamber for supplying a first quantity of warm gas to the cryopump chamber in order to purge the cryopump chamber during regeneration. A roughing valve couples the cryopump chamber to a roughing pump enabling the cryopump chamber to be roughed. An exhaust valve is coupled to the cryopump chamber for exhausting gases from the cryopump chamber during purge. A delivery valve is coupled to the exhaust valve for delivering a second quantity of warm gas directly onto surfaces of the exhaust valve for warming the surfaces of the exhaust valve.

Abstract: A cold trap includes a fluid conduit having a fluid flow path therethrough, a length along the fluid flow path and a width transverse to the fluid flow path. The width of the fluid conduit is greater than the length. A cryopumping array having an outer rim surrounding a central opening is positioned within the fluid conduit transverse to the fluid flow path such that the fluid flow path extends through the central opening of the array. The outer rim captures water vapor from the fluid flow path. The array has a transverse width and a rim width which are both greater than the thickness of the array. A conductive strut extends from the array through the fluid conduit transverse to the fluid flow path for a conductively coupling the array to a cryogenic cooling source which cools the array to cryogenic temperatures.
