Publication number: 20240143725Abstract: A method of determining trust in a supply item in an imaging device for verifying other supply items installed in the imaging device via an algorithm, wherein the imaging device has a plurality of installed supply items. The method comprises: sending challenge data and an indication of the algorithm to a candidate supply item, receiving a challenge response from the candidate supply item, and determining, by the controller, a status of the challenge response, the status being verified or unverified. When the controller determines that the received challenge response is a correct output of the algorithm when the challenge data is input to the algorithm, the status is determined as verified. Further, an imaging device configured to determine trust in a supply item installed in the imaging device for verifying other supply items installed in the imaging device via an algorithm.Type: ApplicationFiled: January 27, 2023Publication date: May 2, 2024Inventors: Samuel Davidson, James Howard Ellis, Zachary Nathan Fister, Timothy John Rademacher, Jennifer Topmiller Williams

Publication number: 20240143726Abstract: An imaging device comprising a controller, a prover supply item and a verifier supply item, where the imaging device is configured to authenticate the prover supply item by: sending a challenge response from the prover supply item to the verifier supply item, and determining a status of the challenge response. When the verifier supply item determines that the received challenge response is a correct output of an algorithm when challenge data is input to the algorithm, the status is determined as verified. A supply item configured to be operable as a prover supply item when installed in an imaging device. The prover supply item is configured to receive an indication of an algorithm to be performed and receive challenge data, perform the algorithm using the challenge data as input to determine a challenge response, and send the challenge response to a verifier supply item.Type: ApplicationFiled: January 27, 2023Publication date: May 2, 2024Inventors: Samuel Davidson, James Howard Ellis, Zachary Nathan Fister, Timothy John Rademacher, Jennifer Topmiller Williams

Publication number: 20240143844Abstract: A method of authenticating a supply item in an imaging device, wherein the supply item is designated as a prover supply item, and a second supply item installed in the imaging device is designated as a verifier supply item. The method comprises: receiving a challenge response from the prover supply item and determining a status of the challenge response. When the verifier supply item determines that the received challenge response is a correct output of an algorithm when challenge data is input to the algorithm, the status is determined as verified. The verifier supply item is disclosed, configured to receive a challenge response from a prover supply item installed in the imaging device, and determine a status of the challenge response. When the verifier supply item determines that the received challenge response is a correct output of an algorithm, the status is determined as verified.Type: ApplicationFiled: January 27, 2023Publication date: May 2, 2024Inventors: Samuel Davidson, James Howard Ellis, Zachary Nathan Fister, Timothy John Rademacher, Jennifer Topmiller Williams

Patent number: 11970409Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.Type: GrantFiled: November 21, 2022Date of Patent: April 30, 2024Assignee: Revive Environmental Technology, LLCInventors: Lindy E. Dejarme, Kavitha Dasu, Russell R. Sirabian, Jeffrey Ellis, Dan Garbark, Nathan Bryant, John Tallarico, Joseph Casciano, Slawomir Winecki, David Holley, Joshua James, Keith Brown, Doug Hendry, Darwin Argumedo, Aaron Frank, Christopher Gordon Scheitlin, Michael M.

Patent number: 7197897Abstract: A salt mixture used for chemical strengthening of data recording disks is subjected to sub-micron filtration prior to use to remove certain impurities. Preferably, glass disks are chemically strengthened by ion exchange in a bath of molten sodium nitrate and potassium nitrate. A salt fresh mixture is prepared by starting with high-grade bulk salt in the intended proportions, melting the salt, and filtering the salt in a stainless steel filter, which is preferably approximately 2 micron or smaller. Filtration removes trace amounts of certain contaminants. The salt mixture thus prepared is then used for chemical strengthening of disks in the conventional manner.Type: GrantFiled: April 4, 2002Date of Patent: April 3, 2007Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Nathan Ellis Jacobson, Terry Lee Jensen, Rick Allan Sprague

Patent number: 6838240Abstract: The present invention provides a method for diagnosing Bloom's syndrome (BS) as well as determining whether a subject is a carrier of a mutated BLM gene. The present invention also provides one or more single-stranded nucleic acid probes and antibodies which may be formulated in kits, and used for diagnosing BS or determining whether a human subject is a carrier of a mutated BLM gene. In addition, the present invention provides a method for treating or preventing the onset of BS in a subject in need of such treatment or prevention, as well as vectors and stem cells useful for such treatment or prevention. The present invention also provides a purified and isolated nucleic acid encoding an enzymatically active BLM protein, a vector comprising this nucleic acid, a cell stably transformed with this vector, as well as a method for producing recombinant, enzymatically active BLM protein. A purified, enzymatically active BLM protein is also provided by the present invention.Type: GrantFiled: January 2, 2001Date of Patent: January 4, 2005Assignees: New York Blood Center, Inc., University of CincinnatiInventors: Nathan Ellis, James German, Joanna Groden

Patent number: 6571964Abstract: A tray for retaining disks includes first and second longitudinally extending, spaced apart, parallel rods. A plurality of support plates are directly attached to the rods. Each support plate has at least one notch formed therein for receiving a respective support member. A plurality of rails are attached to the support plates. At least three spaced apart wires are provided. Each wire is formed to have a zigzag configuration adapted to receive and support the disk at an outer peripheral edge thereof. One of the wires is disposed to contact the outer periphery of the disk at a position of zero degrees, another one of the wires is disposed to contact the outer periphery of the disk at a position less than 90 degrees, and a further one of the wires is disposed to contact the outer periphery of the disk at a position greater than 270 degrees.Type: GrantFiled: March 28, 2001Date of Patent: June 3, 2003Assignee: International Business Machines CorporationInventors: Nathan Ellis Jacobson, Mark LeMarr Kyllo, Steven F.
