Patent number: 12146582Abstract: There is provided an automated bi-stable valve system. The system includes a bi-stable valve mechanism with bi-stable valves. Each of the bi-stable valves is configured to switch between a valve closed state and a valve open state. The system includes a control system coupled to the bi-stable valve mechanism and configured to operably control the bi-stable valve mechanism. The control system includes, (i) at least one traversable bridge apparatus, and (ii) a valve switch mechanism attached to the traversable bridge apparatus, and movable, via the traversable bridge apparatus, over the bi-stable valves. The valve switch mechanism is configured to switch the bi-stable valve(s) between the valve closed state and the valve open state, to allow for selective control of one or more adhesion zones on the bi-stable valve mechanism. The adhesion zone(s) correspond to adhesion area(s) on a surface of a material to be selectively picked up and placed.Type: GrantFiled: October 6, 2021Date of Patent: November 19, 2024Assignee: The Boeing CompanyInventors: Shaun A. McFetridge, David M. Bain, Benjamin S. Zielinski, Conrad Sevenster

Patent number: 11936308Abstract: Certain aspects of the present disclosure provide an apparatus for grasping an object. The apparatus includes a substrate comprising a plurality of electrode pixels; and a controller configured to energize each electrode pixel of the plurality of electrode pixels individually, wherein the apparatus is configured to grasp an object electrostatically using the substrate.Type: GrantFiled: December 7, 2021Date of Patent: March 19, 2024Assignee: The Boeing CompanyInventors: David M. Bain, Brittany P. Chambers

Patent number: 11831252Abstract: Control for pixelated electrostatic adhesion can be provided by a voltage converter configured to increase an input voltage to an output voltage; a first gripping circuit, configured to selectively provide the output voltage at a first polarity to a first subset of electrodes of a plurality of electrodes; a second gripping circuit, configured to selectively provide the output voltage at a second polarity opposite to the first polarity to a second subset of electrodes of a plurality of electrodes that are associated with and different from the first subset of electrodes; a first release circuit, configured to selectively reverse the output voltage provided to the first subset of electrodes to the second polarity; and a second release circuit, configured to selectively reverse the output voltage provided to the second subset of electrodes to the first polarity.Type: GrantFiled: December 7, 2021Date of Patent: November 28, 2023Assignee: THE BOEING COMPANYInventors: David M. Bain, Craig J. Turner, Peter W. Chew, Brittany P. Chambers

Patent number: 10788813Abstract: Systems and methods for retuning a surface to a nominal geometry using local reference points are disclosed. The system can include an imaging device for detecting the location of local features on an object. The system can use the location of local features, as opposed to an absolute reference frame, to determine one or more reference areas and one or more surface defects on an object. The system can then determine a nominal geometry for the surface (i.e., a surface that is substantially free of surface defects) and calculate the tool path necessary to create a nominal geometry. The system can machine the surface and, in some cases, rescan the surface to ensure the operation has machined the part to the nominal geometry.Type: GrantFiled: October 28, 2014Date of Patent: September 29, 2020Assignee: The Boeing CompanyInventors: Martin A. Szarski, David M. Bain, Phillip J. Crothers

Patent number: 10139806Abstract: Systems and methods for generating a coordinate transformation are disclosed. The system can include a non-destructive imaging (NDI) device for detecting the location of local surface and subsurface features in an object (e.g., an aircraft). The system can compare the location of these local features to the location of features from engineering drawings (e.g., CAD files) to generate a coordinate transformation from a machine coordinate system, for example, to an absolute coordinate system. The system can then accurately locate a work piece to perform repairs or replacements, as necessary. The system can also include a robotic arm to enable repairs to be performed at reduced cost and with increased accuracy. The system can also compare two or more NDI scans to locate or relocate a machine that has been moved. This can enable the machine to be repositioned for repairs, maintenance, or to perform a two part repair.Type: GrantFiled: January 12, 2015Date of Patent: November 27, 2018Assignee: The Boeing CompanyInventors: Martin A. Szarski, David M. Bain, Phillip J. Crothers
