Breathalyzer

A Breathalyzer is a device used to measure the blood alcohol concentration (BAC) in a person's breath. It works by analyzing the breath of an individual after they have consumed alcohol. When a person exhales into the device, it estimates the amount of alcohol in their bloodstream based on the concentration of alcohol vapor in the breath. Breathalyzers are commonly used by law enforcement officers to test drivers for intoxication during traffic stops or sobriety checkpoints.

BACtrack is a company known for its production of personal breathalyzers designed to measure blood alcohol content (BAC). Their devices allow users to estimate their level of intoxication by analyzing the amount of alcohol present in their breath. BACtrack offers a variety of models ranging from compact, portable units to more advanced smartphone-connected devices that provide detailed readings and additional features, such as tracking alcohol consumption over time and sharing results.

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. The background of the case involved a driver, Tyler Birchfield, who was arrested for DUI in North Dakota. He refused to submit to a blood test but was subjected to a breath test, which he complied with.

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.

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.

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.

Mitchell v. Wisconsin is a significant case decided by the U.S. Supreme Court in 2019. The case addressed the Fourth Amendment, specifically issues related to warrantless blood draws in the context of drunken driving cases. In this case, the defendant, Gerald Mitchell, was arrested for operating a vehicle while intoxicated. After he was taken into custody, he became unconscious, and the police decided to conduct a blood draw without a warrant to determine his blood alcohol content.

Robert Frank Borkenstein (1912–2002) was a notable American scientist and researcher, best known for his contributions to the field of forensic science, particularly in the development of breath alcohol testing devices. Borkenstein invented the Breathalyzer, a device that measures blood alcohol content (BAC) from a breath sample. His work played a significant role in promoting public safety and law enforcement practices related to driving under the influence (DUI).

Rolla Neil Harger was an American astronomer and physicist known for his contributions in the field of astrophysics and astronomical research. He is often recognized for his work with meteorites and his research on cosmic rays. One of his notable contributions is the development of the Harger-Cheyne method for measuring the effectiveness of meteorite collection in specific geographic areas.

William Duncan McNally is not a widely recognized public figure or concept in historical or contemporary contexts, based on the information available up until October 2021.
