Tunable Phenylacetylene Hosts

View page
US Patent:
20080167472, Jul 10, 2008
Filed:
Dec 14, 2007
Appl. No.:
11/957243
Inventors:
Michael M. Haley - Eugene OR, US
Darren W. Johnson - Eugene OR, US
Orion B. Berryman - Eugene OR, US
Charles A. Johnson - Alexandria VA, US
Calden N. Stimpson - Eugene OR, US
International Classification:
C07D 213/22
C07D 213/00
C07D 333/02
US Classification:
546257, 546338, 546337, 549 75
Abstract:
Disclosed herein is a class of tunable phenylacetylene compounds as well as compositions and methods for their use as host compounds for ligand binding. In certain examples the hosts report binding events by exhibiting altered spectroscopic properties, such as different fluorescent emission spectra.

System, Apparatus, And Method For Measuring Ion Concentration With A Standard Deviation Correction

View page
US Patent:
20200249215, Aug 6, 2020
Filed:
Mar 2, 2020
Appl. No.:
16/806129
Inventors:
- Eugene OR, US
JORDAN RICHARD KUSIEK - Eugene OR, US
CALDEN CARROLL STIMPSON - Eugene OR, US
SEAN FONTENOT - Eugene OR, US
International Classification:
G01N 33/24
Abstract:
Embodiments of the inventive concept include a portable ion concentration apparatus including a controller, a storage section to store one or more data samples, an amplifier circuit, and a chemical field effect transistor (CHEMFET). The CHEMFET and the amplifier circuit can indicate a quantity of nitrate levels in a sample media or a reference media. The controller can process the indication of the quantity of nitrate levels, and generate the one or more data samples based at least on the indication of the quantity of nitrate levels. The portable ion concentration apparatus can include an in-field analysis apparatus, an in-field measurement apparatus, or an in-soil monitoring apparatus. A measurement logic section can determine an ion concentration based on a sensitivity slope M or a polynomial fit. Also disclosed is a method for measuring ion concentration with a standard deviation correction.
