Patent number: 9395373Abstract: A method of determining concentrations of a plurality of analytes from a single blood sample placed in a single opening. A portion of the single blood sample is absorbed by a test matrix that includes a plurality of layers and a chromogenic agent. A colored response is generated by the test matrix. The colored response is proportional to the concentration of a first analyte. A portion of the single blood sample is drawn into a capillary tube and placed in contact with an electrode and a counter-electrode. An electrical property of the single blood sample is analyzed through the electrode and counter-electrode. The electrical property is proportional to the concentration of a second analyte in the single blood sample.Type: GrantFiled: March 15, 2013Date of Patent: July 19, 2016Assignee: Polymer Technology Systems, Inc.Inventors: Robert Huffstodt, James J.

Patent number: 8465696Abstract: A dry test strip assembly includes: a carrier base having a test port and a well adapted for receiving a dry test strip element, and a cover having a sample opening. The cover can be snapped onto the base with the sample opening aligned over the test port and with a test strip element compressed between the base and cover. A maximum dry test strip compression stop controls the maximum compression on the dry test strip, and a minimum dry test strip compression stop controls the minimum compression on the dry test strip. A rib between two test ports prevents fluid flow in the dry test strip element from one side of the rib to another, thereby separating the test strip element into a plurality of separate fluid compartments. A manufacturing system efficiently assembles the dry test strip assembly without handling by humans.Type: GrantFiled: October 31, 2007Date of Patent: June 18, 2013Assignee: Polymer Technology Systems, Inc.Inventors: Robert Huffstodt, John P. Hancock, Emmanuel Paul Crabtree, James J. Sutor, Kimberly Zinser Huffstodt, Gregory M. Lawrence

Patent number: 5648124Abstract: Magnetically responsive microparticles and a method for their production are described. Oppositely charged core particles and magnetite are heterocoagulated, redispersed and optionally coated. The microparticles are colloidally stable and have negligible retentivity.Having now fully described the invention, it will be apparent to one of ordinary skill in the art that many changes and modifications can be made thereto without departing from the spirit or scope of the invention as set forth herein.Type: GrantFiled: May 22, 1995Date of Patent: July 15, 1997Assignee: Seradyn, Inc.Inventor: James J.

Patent number: 5003069Abstract: In a Chichibabin amination of a nitrogen-containing heterocyclic base by sodamide in an organic solvent, the improvement comprising conducting the reaction under pressure of at least about 50 psi in the gas phase above the reaction mixture and adding ammonia to the mixture sufficient to produce a partial pressure of ammonia of at least about 5 psi in the gas phase. Preferred temperature and pressure ranges are disclosed, as are catalysts and other preferred steps for practicing the reaction. Significant results are obtained including improved and changed yields from those classically expected in Chichibabin aminations, including new compositions of matter in at least three cases.Type: GrantFiled: July 26, 1989Date of Patent: March 26, 1991Assignee: Reilly Industries, Inc.Inventors: Charles K. McGill, James J. Sutor
