Patent number: 11951433Abstract: Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.Type: GrantFiled: April 26, 2022Date of Patent: April 9, 2024Assignee: Donaldson Company, Inc.Inventors: Steven K Campbell, Robert D.

Patent number: 11941179Abstract: A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.Type: GrantFiled: December 13, 2021Date of Patent: March 26, 2024Assignee: NuVasive, Inc.Inventors: Robert E. Isaacs, Samuel Morris Johnston, David Alexander Skwerer, Randall Graham Campbell

Publication number: 20180209968Abstract: A novel assay for determining a molecular process using a fluorescent protein exchange assay, and a composition for use thereof, are provided. The assay provides first and second signalling proteins and an exchange protein, wherein the exchange protein interacts with the first signalling protein to form a complex, then introducing the second signalling protein, wherein in response to the molecular process, the exchange protein dissociates from the first protein and associates with the second protein. The change in signal in response to the exchange of the proteins is measured to indicate a molecular process.Type: ApplicationFiled: March 21, 2018Publication date: July 26, 2018Inventors: Robert E.

Patent number: 9038051Abstract: The present invention provides patch solutions for computer programs. A vendor system determines whether information regarding patches previously installed on the system is available. If the information is not available, the system delivers a completely pre-computed solution to the user computer system including a main patch set and its dependencies. If the information is available, the vendor system delivers a partially pre-computed solution including a main patch set and its dependencies except for any of said patches that have successors already installed on said system.Type: GrantFiled: October 31, 2006Date of Patent: May 19, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Evan R.

Patent number: 7940532Abstract: The present invention relates, generally, to electrical power conversion devices and to the universal packaging of those devices for a wide range of applications yielding cost efficient inventory management of product lines consisting of a group of power conversion devices each with minor variations. More specifically, the present invention relates to a universal mounting frame for receiving a printed circuit board in a switch mode power supply. The universal frame is adapted for receiving an open frame or printed circuit board and securing the open frame within a plurality of known packaging configurations. To this end, only a single size printed circuit board is necessary for any type of switch mode power supply configurations, thereby, reducing costs associated with manufacture and testing.Type: GrantFiled: May 2, 2008Date of Patent: May 10, 2011Assignee: PEI-Genesis, Inc.Inventors: Steven Lee Willing, Kent Carlson, Robert E.
