Patent number: 8757026Abstract: A robot with improved cleanliness for use in a clean environment is disclosed, having a uniform flow through the open interface between the clean environment and the interior of the robot housing, passing the particle generation area to an exhaust port, keeping the particles from the clean environment. The uniform flow reduces or eliminates the back flow, and further allows the scalability of the open interface to prevent particles generated from moving mechanisms within the robot housing to contaminate the clean environment. The uniform flow can be established by designing the flow dynamic, centering the exhaust port, or by restricting the flow along the elongated slot, for example, by uniformly restricting the flow along the elongated slot, or by implementing a restrictor along the elongated slot.Type: GrantFiled: April 15, 2008Date of Patent: June 24, 2014Assignee: Dynamic Micro Systems, Semiconductor Equipment GmbHInventors: David Barker, Robert T.

Patent number: 8668422Abstract: As part of a system for processing workpieces, a workpiece support arrangement, separate from a process chamber arrangement supports at least two workpieces at least generally in a stacked relationship to form a workpiece column. A transfer arrangement transports at least two of the workpieces between the workpiece column and the process chamber arrangement by simultaneously moving the two workpieces at least generally along first and second transfer paths, respectively, that are defined between the workpiece column and the first and second process stations. The transfer arrangement can simultaneously move untreated and treated workpieces. Vertical motion swing arms and coaxial swing arms are described. A pair of spaced apart swing arms, the workpiece column and the processing stations can cooperatively define a pentagonal shape. Timing belt backlash elimination, a dual degree of freedom slot valve and low point chamber pumping, for removing chamber contaminants, are also described.Type: GrantFiled: August 17, 2004Date of Patent: March 11, 2014Assignee: Mattson Technology, Inc.Inventors: Leszek Niewmierzycki, David Barker, Daniel J.

Patent number: 8641277Abstract: Systems and methods for making and using sliding counterbalanced C-arm positioning devices are described. In such systems and methods, each C-arm positioning device includes a C-arm X-ray device, a linear bearing rail, a linear bearing block, and a counterbalance mechanism. Generally, the C-arm is connected to the linear bearing block, which, in turn, is slidably coupled to the bearing rail to allow the bearing block and C-arm to slide up and down on the rail. The counterbalance mechanism can apply a force to the bearing block to counterbalance the weight of the C-arm and the bearing block. Thus, the described C-arm positioning device can allow a user to easily raise or lower the C-arm with relatively little effort. While some implementations of the C-arm positioning device are connected to mobile support structure, other implementations of the C-arm positioning device are mounted to a fixed support structure. Other implementations are also described.Type: GrantFiled: April 3, 2013Date of Patent: February 4, 2014Assignee: General Electric CompanyInventors: John Matthew Simmons, David Barker, Jan Bruening

Publication number: 20130272499Abstract: Systems and methods for controlling an X-ray imaging system are described. The systems and methods typically include a support arm with a first end and a second end. The first end of the support arm connects to an articulating arm assembly and the second end of the support arm pivotally attaches to an X-ray imaging arm at a pivot joint so that the pivot joint functions as an axis of orbital rotation for the X-ray imaging arm. One or more controls for the X-ray imaging system are disposed on the support arm for the X-ray imaging arm. The controls can therefore remain stationary while the X-ray imaging arm rotates orbitally. The support arm can include a single member or a double member and one or more controls can be disposed on each member of the support arm. Other embodiments are also described.Type: ApplicationFiled: April 13, 2012Publication date: October 17, 2013Inventors: John Matthew Simmons, David Barker, Samuel Alder, Bret Nicholson, Robert Bruce Spratt, JR.

Publication number: 20130259195Abstract: Systems and methods for obtaining and displaying a collimated X-ray image are described. The methods can include providing an X-ray device having an X-ray source, a square or rectangular X-ray detector, and a collimator. The collimator can be sized and shaped to collimate an X-ray beam from the X-ray source that exposes a receptor region on the detector. The collimator can allow the X-ray image received by the X-ray detector to have any suitable shape that allows a relatively large view of the image to be displayed and rotated on the display device without changing the shape or size of the image as it rotated. In some instances, the collimator provides the image with superellipse shapes or cornerless shapes having four substantially straight edges with a 90 degree corner missing between at least two edges that run substantially perpendicular to each other. Other embodiments are described.Type: ApplicationFiled: March 29, 2012Publication date: October 3, 2013Applicant: General Electric CompanyInventors: Bret David Nicholson, David Barker

Patent number: 8465203Abstract: Systems and methods for using a brake system to selectively lock and release the vertical motion of a C-arm X-ray device that is part of a sliding counterbalanced C-arm positioning device are described. In such systems and methods, the C-arm positioning device typically includes a C-arm X-ray device, a linear bearing rail assembly, a linear bearing block, a counterbalance mechanism, and brake system. Generally, the C-arm is connected to the linear bearing block, which is slidably coupled to the bearing rail assembly to allow the bearing block and C-arm to slide up and down on the rail assembly. The counterbalance mechanism applies a force to the bearing block to substantially counterbalance the weight of the components, such as the C-arm, that are suspended from the bearing block. The brake system can be actuated to engage the linear bearing rail assembly and lock the vertical movement of the linear bearing block. Other embodiments are described.Type: GrantFiled: March 2, 2011Date of Patent: June 18, 2013Assignee: General Electric CompanyInventors: David Barker, John Matthew Simmons, Jan Bruening

Publication number: 20130044860Abstract: Systems and methods for making and using a multi-blade collimator device are described herein. The collimator device can include a base member, a rotational member, and multiple X-ray-attenuating blades that fit together to define an aperture. The blades are typically disposed between the base member and rotational member. Additionally, the blades can be mechanically connected to or interfaced with the base member and the rotational member so that when the rotational member is rotated with respect to the base member, the blades move and cause the aperture to change in size. The aperture can be any shape, including polygonal, square, or rectangular. While the aperture's size can be increased and decreased, the shape and orientation of the aperture can remain substantially constant. The collimator can contain a single layer of blades or multiple layers of blades. Other embodiments are described.Type: ApplicationFiled: August 17, 2011Publication date: February 21, 2013Inventors: Bret D. Nicholson, David Barker
