Intoxalock is a brand that provides ignition interlock devices (IIDs), which are breathalyzer devices installed in vehicles to prevent impaired driving. These devices require the driver to submit a breath sample to measure their blood alcohol concentration (BAC) before the vehicle can be started. If the BAC is above a certain limit, the vehicle will not start. Intoxalock services are often used as part of court-ordered requirements for individuals convicted of DUI (driving under the influence) offenses.

A coronavirus breathalyzer is a diagnostic tool designed to detect COVID-19 infection through breath samples. It operates on the principle that individuals infected with the virus may release certain volatile organic compounds (VOCs) or other biomarkers in their breath that can be identified through specialized sensors or analytical techniques. The concept of using breath analysis for disease detection is not new, and researchers have been exploring it for various conditions, including infections, metabolic disorders, and even some types of cancer.

Breathometer is a portable device designed to measure blood alcohol content (BAC) by analyzing a person's breath. Originally launched as a smartphone accessory, it allowed users to check their alcohol levels by blowing into the device, which then communicated with a mobile app to provide readings and feedback. The concept was aimed at promoting responsible drinking by helping individuals make informed decisions about their alcohol consumption. However, the company faced legal and regulatory challenges, and there were concerns regarding the accuracy and reliability of the device.

Birchfield v. North Dakota is a significant U.S. Supreme Court case decided in 2016. The case primarily addressed the issue of whether law enforcement can conduct warrantless breath tests and blood tests on individuals suspected of driving under the influence (DUI) of alcohol.
