Patent number: 11056647Abstract: A carbon nanotube (CNT) single ion memory (or memory device) may include a mobile ion conductor with a CNT on one side and an ion drift electrode (IDE) on the other side. The mobile ion conductor may be used as a transport medium to shuttle ions to and from the CNT and the IDE. The IDE may move the ions towards or away from the CNT.Type: GrantFiled: July 27, 2017Date of Patent: July 6, 2021Assignee: The Aerospace CorporationInventors: Adam W. Bushmaker, Don Walker

Patent number: 10615744Abstract: An apparatus for carrying, retrieving, and characterizing temperature and current-voltage properties of a solar cell may include a metal core printed circuit board (PCB). The metal core PCB includes current-voltage and temperature measurement electronics operated by a remote device via a communication unit. The solar cell is embedded onto the metal core PCB by way of a thermally- and electrically-conducting adhesive material. The current-voltage and temperature electronics and the solar cell are thermally connected to the PCB, and are electrically isolated from each other, while residing on the same plane.Type: GrantFiled: August 13, 2017Date of Patent: April 7, 2020Assignee: The Aerospace CorporationInventors: Colin J. Mann, Don Walker, John C. Nocerino, Justin H. Lee

Patent number: 8744162Abstract: A method and system for evaluating images, such as x-ray image, to provide feedback that can be used for subsequent image acquisition. The feedback may be used to adjust the positioning of a patient with respect to an image capture device, or a setting of the image capture device. The image capture device may be part of a dental x-ray imaging system that generates an x-ray image of the patent and provides the image to a collector service. The image is evaluated by the collector service for positioning errors and other operator correctable issues that may have had an impact on the image quality. A report that includes feedback regarding the operator correctable issues, as well as suggested corrective action, is generated and provided to the imaging system operator.Type: GrantFiled: March 23, 2012Date of Patent: June 3, 2014Assignee: Midmark CorporationInventors: Mark Greenwood, Edwin McDonough, Bradley McDougall, Don Walker

Publication number: 20070011373Abstract: A system and method is disclosed for encoding a set of configuration data for a given expander and at some later point comparing the configuration data to a discovered configuration derived from an attempt to discover the operability of each phy or connection point of the storage system. The configuration identifies the phys or connection points that are operable and the mapping of operable connection points to wide ports communicatively of an expander.Type: ApplicationFiled: July 11, 2005Publication date: January 11, 2007Inventors: Kevin Marks, Don Walker

Publication number: 20060113330Abstract: There is a significant market for liquid detergent bottles in the approximate size of 100 fluid ounces. The advantages of this size and design of current containers include convenient value bulk size and the ability to pick up and grasp with one hand for transport and use. A major disadvantage of current designs is that this size and weight container are at the upper limit of what a small woman or elderly user can comfortably hold. A further disadvantage is that the current use/operating sequence of unscrewing the cap, pouring the bottle into the cap, dispensing the cap and then re-attaching the cap requires the careful use of both hands. A final disadvantage is that undesirable residue from the liquid often adheres to rim and surfaces on and around the container due to drips and spills. The objective of this new and improved design is to provide a container that is both easier to use and cleaner to operate, through an automatic, self-dispensing operation that reseals itself after use.Type: ApplicationFiled: November 30, 2004Publication date: June 1, 2006Inventors: Don Walker, Jerrod Windham, Lloyd Cooper
