Abstract: A system for producing a high precision blended gas product (BGP), the system comprising: a supply of a volatile analyte in liquid form; a supply of an inert carrier gas; a supply of at least one diluent gas; an analyte gasifier (AG) subsystem for receiving the volatile analyte in liquid form, nebulizing the volatile analyte and mixing the nebulized volatile analyte with the inert carrier gas so as to form an analyte gas stream (AGS); and a gas mixer (GM) subsystem for receiving the AGS from the AG subsystem and mixing the AGS with the supply of at least one diluent gas so as to produce the BGP, wherein the GM subsystem comprises: a gas analyzer (GA) for receiving the AGS and analyzing the same; a gas proportioner for receiving the AGS from the GA, receiving the at least one diluent gas, and proportioning the AGS and the at least one diluent gas based on the results of the GA so as to provide a proportioned AGS and a proportioned at least one diluent gas; and a gas mixing chamber for receiving the proportione

Abstract: A system for controlling operation of a vehicle, the system comprising: a voice synthesizer unit for providing voice communication to a driver; a speech recognition unit for receiving speech from a driver; a breath alcohol sensor unit for detecting a presence of alcohol on the breath of a driver and providing a signal representative of the same; a vehicle operation interface for controlling operation of the vehicle; and a controller for (i) selectively causing the voice synthesizer unit to speak to the driver, (ii) operating the speech recognition unit to detect speech by the driver, (iii) receiving the signal from the breath alcohol sensor unit, and (iv) depending on the signal received from the breath alcohol sensor unit, providing a command to the vehicle operation interface to control operation of the vehicle.
