Body worn video (police equipment) prepared for the United States Department of Justice in 2016 is that body worn cameras "are cameras with at least one microphone and internal data storage, and allow audio/video footage to be stored and analyzed with compatible software. The cameras are typically located on the police officer's chest or head".

Current body cameras are much lighter and smaller than the first experiments with wearable cameras as early as 1998. There are several types of body cameras made by
Effect of spaceflight on the human body see how well a pressurized space suit prototype would perform in vacuum conditions. To simulate the effects of space, NASA constructed a massive vacuum chamber from which all air could be pumped. At some point during the test, LeBlanc's pressurization hose became detached from the space suit. Even though this caused his suit pressure to drop from to in less than 10 seconds, LeBlanc remained conscious for about 14 seconds before losing consciousness due to hypoxia; the much lower pressure outside the body causes rapid de-oxygenation of the blood. “As I stumbled backwards, I could feel the saliva on my
