Publication number: 20210220210Abstract: An apparatus to treat, inhibit, or prevent an indication of a headache symptom in a patient can include a cover, sized and shaped to fit over an eye of the patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient cavity pressure to the cavity. The apparatus can include control circuitry, in communication with the pressure source, the control circuitry storing or otherwise configured to define a target cavity pressure value specified to treat, inhibit, or prevent the headache symptom, and configured to control the pressure source to adjust the cavity pressure toward the target cavity pressure value to treat, inhibit, or prevent the headache symptom.Type: ApplicationFiled: April 8, 2021Publication date: July 22, 2021Inventors: John Berdahl, Paul Byoungjae Yoo, Matthew Donald Larson, Gary Berman, George Tsai

Publication number: 20160191483Abstract: A Universal Connector (“UC”) ecosystem includes encrypted twin (first and second) communications stacks configured to supervise persistent connectivity with distributed data collection points within an Internet of Things. Everything that interacts with the UC ecosystem follows a simple registration process: (1) devices participate on the first stack by requesting to be adopted by logging into the Cloud Service (the “knowledge” factor, they phone home); (2) if validated as an ecosystem device, it is placed into the adoption process and proceeds to the next layer of authentication; and (3) the second stack represents applications (mobile and web) that continue the adoption process for the user/owner (the possession factor). The owner creates an account, then associates the device to the account created, and if all authentication factors are confirmed, the device is adopted and registered to the user/owner completing the adoption process.Type: ApplicationFiled: July 17, 2015Publication date: June 30, 2016Inventors: Donald Larson, Navid Mitchell, Nicholas Padilla

Publication number: 20140067776Abstract: When one considers all of the servers at an organization, the exact same operating system and application files will appear on many of them. Thus, there is an opportunity for saving an enormous amount of disk space for the organization as a whole by de-duplicating stored files. The present invention addresses the above needs by providing a method and system for saving at least one copy of a duplicate file in a location on a common storage system accessible to all relevant server computers and then removing the duplicates from the storage allocated to each server. Whenever the operating system on a server whose duplicate file has been removed requires access to the file, then the method redirects the operating system to access the file from the common storage system file location.Type: ApplicationFiled: August 26, 2013Publication date: March 6, 2014Inventors: Matthew Donald Larson, Brett Derek Hawton

Patent number: 8663355Abstract: Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising strips of fluted material secured to facing sheets, oriented in a stack. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The media pack is non-removably secured within a filter cartridge housing, at a location between opposite sections of a shell, typically secured thereto with an adhesive. The shell also defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack. The closed end is typically curved and the shell typically provides either a d/b-shape or a u-shape.Type: GrantFiled: July 9, 2012Date of Patent: March 4, 2014Assignee: Donaldson Company, Inc.Inventors: Benny Nelson, John Kuhn, Donald Larson, David Nelson
