20140311214 | Portable Wet Calibration System for Handheld Breath Testers - Devices and systems for methods for calibrating breath alcohol testing and measuring equipment, or checking the accuracy of such equipment without calibration, using a permeable membrane to separate liquid and gas reservoirs and maintain an equilibrium state as samples are drawn from the device. | 10-23-2014 |
20140251835 | Fuel Cell Fermentation Monitor - Systems and methods for implementing an automated process which calculates the current specific gravity of a liquid by using the original gravity of a fermenting liquid and a measurement of the percent alcohol by volume. | 09-11-2014 |
20140230518 | Calibration and Accuracy Check System - Calibration and accuracy check systems for a chemical sniffer, such as a breath alcohol tester, which utilize the dispensing of droplets with determinable concentration of alcohol and/or other liquids in a determinable number either directly to a reaction chamber, or into a carrier gas which can be sampled. The systems generally provide for accurate sample concentration being provided to the breath tester while also providing for a simplified system which can be easier to move, and require less operational complexity, than prior wet or dry calibrating systems. | 08-21-2014 |
20140034492 | Fuel Cell Housing for Use in an Alcohol Breath Tester - An alcohol fuel cell sensor and the resultant alcohol breath tester assembly. The disclosed housing creates an alcohol breath tester assembly that protects the electrode sensor from liquid ingress, maximizes the sample contact with the platinum electrode surface, and provides a smooth path facilitating laminar flow of the sample through the sensor. This, in turn, provides good flushing of the volume without creating eddies or other turbulence. Additionally, the housing can utilize a vapor barrier layer in the assembly and restricts the layer from touching the electrode surface. | 02-06-2014 |
20140027281 | Fuel Cell for Use in an Alcohol Breath Tester - An improved alcohol fuel cell sensor and alcohol breath tester assembly where wires for connection to the electrodes are bent to have a generally planar base portion which may be positioned toward the center of the electrodes and an upright that then extends to the outside of the case. The uprights are generally perpendicular to the base allowing the wires to exit the housing toward the center, as opposed to toward an edge. | 01-30-2014 |
20130156647 | Calibration and Accuracy Check System - Calibration and accuracy check systems for a chemical sniffer, such as a breath alcohol tester, which utilize the dispensing of droplets with determinable concentration of alcohol and/or other liquids in a determinable number either directly to a reaction chamber, or into a carrier gas which can be sampled. The systems generally provide for accurate sample concentration being provided to the breath tester while also providing for a simplified system which can be easier to move, and require less operational complexity, than prior wet or dry calibrating systems. | 06-20-2013 |
20110060554 | Interference Detector and Methods - Interference detector and methods for detecting interference in a signal are described. More specifically, in one aspect, a method for detecting interference in a signal is provided. The method comprises determining whether the signal has at least one of a time and a frequency characteristic that is outside a predefined range, and determining that an interference event has been detected if the signal has at least one of such characteristics. | 03-10-2011 |
