Patent CA-3126240-A1 (CA)
Title: Analyte sensors employing multiple enzymes and methods associated therewith
Inventor: OJA STEPHEN
IPC: A61B5/1486
Filed: 2020-01-28
Abstract: Multiple enzymes may be present in the active area(s) of an electrochemical sensor to facilitate analysis of analytes. The multiple enzymes may function independently to detect several analytes or in concert to detect a single analyte. One configuration includes a first active area and a second active area, where the first active area has an oxidation-reduction potential that is sufficiently separated from the oxidation-reduction potential of the second active area to allow independent signal production. Some configurations may have an active area overcoated with a multi-component membrane containing two or more different membrane polymers. Sensor configurations having multiple enzymes capable of interacting in concert include those in which a first enzyme converts an analyte into a first product and a second enzyme converts the first product into a second product, thereby generating a signal at a working electrode that is proportional to the analyte concentration.

Inventor: FAN YIJING
IPC: E21B44/00
Filed: 2019-03-05
Abstract: A method includes generating a ranging model of a drilling wellbore to be drilled and generating a predicted signal along measured depths of the drilling wellbore based on the ranging model. The method includes performing the following operations until the drilling wellbore has been drilled to a defined depth. The following operations include drilling, with a drill string, the drilling wellbore to an increment of the defined depth and detecting, by a sensor positioned on the drill string, an electromagnetic field emanating from a target wellbore. The following operations include determining ranging measurements to the target wellbore at the increment based on the electromagnetic field and calibrating the predicted signal based on the ranging measurements. The following operations include determining ranging accuracy for all deeper depths in the wellbore and making drilling decisions or adjusting drilling operations based on the predicted ranging accuracy for deeper depths.

Inventor: FISHER MARK R
IPC: B41M5/42
Filed: 2020-11-20
Abstract: Dispersible record materials or media include a water-soluble or water-dispersible paper substrate, a printable layer carried by the substrate, and a base coat between the substrate and the printable layer. The printable layer may be a thermally responsive layer, e.g. containing a leuco dye and an acidic color developer, or an inkjet receptive layer. The binder material used in the base coat, and the base coat itself, are non-water-soluble, but nevertheless tailored in such a way that the record material as a whole is water-dispersible, i.e., it breaks apart under the influence of water with minimal agitation. The binder material of the base coat is preferably a non-resinous binder, a particulate binder, and/or a binder derived from a dispersion, such as latex. Use of such a binder material in a carefully selected concentration, with other elements, provides a base coat that allows for high quality images to be thermally printed at high print speeds on the thermally responsive layer.
