Patent number: 11772089Abstract: Disclosed are methods for forming a supported catalyst and catalysts formed according to disclosed methods. Methods include contacting a catalyst support with a precursor solution and displacing the solvent of the precursor solution (e.g., water) with a second solvent that has a lower surface tension than the first solvent. The second solvent displaces the first solution according to the Marangoni effect. Methods also include activation of the precursor to form a catalyst, e.g., a supported platinum group metal catalyst or the like.Type: GrantFiled: June 2, 2022Date of Patent: October 3, 2023Assignee: University of South CarolinaInventors: Abolfazl Shakouri, Horie Adabi Firouzjaie, John R. Regalbuto, Christopher T. Williams, William E. Mustain

Patent number: 10750345Abstract: Technology for securely processing emergency response. The technology includes combining video data from multiple video sources relating to an emergency response scenario. The video data is combined into a multi-video feed that utilizes a particular amount of bandwidth when delivered. From a display of a multi-video feed, a video source may be selected. A single-video feed is then delivered for the selected video source and the single video feed is utilized substantially the same bandwidth and the multi-video feed. Dynamic geofences may also be generated. The dynamic geofence is based on an object that is capable of moving. When the object moves, the dynamic geofence also moves such that the boundaries of the dynamic geofence are fixed relative to the object, even as the object moves. Group members may be associated with the dynamic geofence such that they are alerted when a group member crosses the dynamic geofence boundary.Type: GrantFiled: July 12, 2019Date of Patent: August 18, 2020Assignee: DIGITAL MANAGEMENT, LLCInventors: Christopher Tengwall, Eric Harris, Joseph W. Cole, Jr., Jeremy R. Hettenhouser, Richard P. Cann, Christopher T. Williams

Patent number: 9769639Abstract: Technology for securely processing emergency response. An emergency response server receives intermittent location data from a client device during non-emergency responses. Upon determining an emergency situation is occurring, the emergency response server sends an unencrypted notification to a client device to activate the client device remotely. Once the emergency response server receives an encrypted message from the client device, the emergency response server sends an encrypted emergency client device, causing the client device to enter an emergency mode. The emergency response server then receives encrypted location information at more frequent intervals from the client device in the emergency mode and displays the location of the client device. Once the emergency situation has ended, the location of the client device is no longer displayed, and a signal is sent to cause the client device to exit the emergency mode.Type: GrantFiled: December 21, 2015Date of Patent: September 19, 2017Assignee: Digital Management, LLCInventors: Joseph W.

Patent number: 7582586Abstract: There is disclosed a process for producing a catalyst. The process includes the steps of: a) combining a dendrimer polymer and metal salt in solution forming a metal ion complex; b) exposing the metal ion complex to a reducing environment forming a dendrimer metal nanocomposite; c) depositing the dendrimer metal nanocomposite onto a catalyst support material; d) removing a solvent from the dendrimer metal nanocomposite forming metal clusters; and e) removing the dendrimer polymer forming a catalyst. Additionally, there is disclosed a catalyst having a catalytic metal deposited on a substrate. The catalytic metal is formed in clusters having a size of from 2 to 150 atoms. In another aspect, the clusters may have a spacing of from 2 to 100 nanometers between adjacent metal clusters. Further, in another aspect, the metal clusters which comprise the catalyst have a size distribution in which 70% of the clusters are within 0.6 nm of the average diameter and 99% of the particles are within 1.Type: GrantFiled: August 24, 2006Date of Patent: September 1, 2009Assignees: Toyota Motor Corporation, Toyotal Motor Engineering & Manufacturing North America, Inc.Inventors: Paul T. Fanson, Hirohito Hirata, Michael D. Amiridis, Christopher T. Williams, David S. Deutsch, Attilio Siani, Shinichi Matsumoto
