The system identifyies a particular angular indication being displayed by the light-based protractor. The system then identifies a target color of the physical coating surface and identifies one or more target coating texture characteristics of the physical coating surface. Additionally, the system identifies a proposed coating that comprises a proposed color that matches the target color and proposed coating characteristics that match the one or more target coating texture characteristics. The system then displays, on a user interface, the proposed coating.

Abstract: A method is disclosed for controlling auto-exposure settings of a mobile device when capturing an image of a color reference card and of a test field. Provided are a color reference card and an optical test strip having the test field with a sample applied thereto. The color reference card has different color reference fields having known reference color values and one or more gray background fields having defined gray values. An exposure metering area is set and auto-exposure settings are determined based on a scene in the exposure metering area. The scene has at least part of the test field and at least part of the different color reference fields and the one or more gray background fields. The camera captures an image of the scene using the determined auto-exposure settings. A method of determining concentration of analyte in a sample by using a mobile device is also disclosed.

Abstract: A device which: optically detects the presence of, measures the flow rate of, and identifies the characteristics of venting fugitive gas emissions. Specifically the device provides a spectral analysis of emission gas constituents; selective detection of the presence of venting hydrocarbons; measurement of venting emissions flow rates, the measurement of shut-in and flowing venting system pressures and the venting system temperatures. The flow rates are corrected, relative to the detection of the gas constituents and standard temperature and pressure (STP). These devices are configured to collect such data electronically and transmit via various telemetry systems, to a secure remote data network for reporting, access, evaluation, real-time monitoring and archiving as required.
