Patent number: 12222310Abstract: The present invention is directed to membranes, sensors, systems and process for the detection of magnesium ions in protein-containing samples. The novel membranes, sensors, systems, and processes are based upon the discovery that the lipophilicity of the plasticizer (or blend of plasticizers) utilized in the formulation of magnesium ion selective membranes for clinical use is inversely proportional to the sensitivity of the plasticizer(s) and directly proportional to the use life thereof.Type: GrantFiled: October 10, 2023Date of Patent: February 11, 2025Assignee: Siemens Healthcare Diagnostics Inc.Inventors: John Benco, Robert Bergquist

Patent number: 5922934Abstract: A class of corn plants has been developed that are superior as pollinators in the TopCross.RTM. Grain Production System. The plants of this class are larger and more vigorous than many of the current TC Blend.RTM. pollinators. The seed that produces this new class of TC Blend.RTM. pollinators is produced at greater yields and is of greater vigor and quality than that of many current TC Blend.RTM. pollinators. Additionally, the means whereby the seed of this class of plants is produced enables the rapid generation of a wide range of maturities of TC Blend.RTM. pollinators. This greatly expands both the geographic range and the genetic breadth of the TopCross.RTM. grain production system.Type: GrantFiled: March 31, 1997Date of Patent: July 13, 1999Assignee: Optimum Quality Grains, L.L.C.Inventors: Richard Robert Bergquist, Stuart Leonard Kaplan, Douglas Stuart Nubel, Terry J. Foley

Patent number: 5706603Abstract: A novel method of producing corn grain with enhanced quality traits including high oil content has been developed. Through pollination of male-sterile hybrid corn plants by nonisogenic corn plants possessing genes which control the expression of enhanced quality grain traits, grain is obtained possessing such traits much higher than would be expected for self- or cross-pollination. This method can be practiced by farmers using currently accepted farming practices to directly obtain high yields of high-oil corn grain, high-protein corn grain, and other valuable grain for animal feed and other products.Type: GrantFiled: June 5, 1995Date of Patent: January 13, 1998Assignees: E. I. Du Pont de Nemours and Company, Dupont TopCross International, Inc.Inventors: Richard Robert Bergquist, Douglas Stuart Nubel, Donald L. Thompson

Patent number: 5700360Abstract: An elastomer, especially a fluoropolymeric elastomer, meets requirements necessary for use as a gasket in contact with primary membranes of electrochemical sensors of both blood gas and ionic species in blood. The elastomer can electrochemically seal an electrode of a diced chip (sensor) from a sample chamber, and can electrochemically seal electrodes of neighboring diced chips from each other. Significant simplicity in fabrication of multi-sensor analyzers and stopped-flow method using such analyzers is realized.Type: GrantFiled: October 31, 1995Date of Patent: December 23, 1997Assignee: Chiron Diagnostics CorporationInventors: Andy D. C. Chan, Mark W. Boden, John S. Benco, Robert A. Bergquist, Donna S. Orvedahl
