A hard hat is a type of helmet predominantly used in hazardous environments such as industrial or construction sites to protect the head from injury due to falling objects (such as tools and debris), impact with other objects, and electric shock, as well as from rain. Suspension bands inside the helmet spread the helmet's weight and the force ...
Arai Helmet Limited (株式会社 アライヘルメット, Kabushiki-gaisha Arai Herumetto) is a Japanese company that designs and manufactures motorcycle helmets and other helmets for motorsports. The business has roots from the turn of the century involving cap production, followed by military headgear from 1930 onwards, industrial safety ...
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards , and airborne particulate matter .
The M1971 helmet (Also known as M71) is a military steel combat helmet used by Switzerland from its formal introduction in 1971 until its gradual replacement by the Schuberth B826 (known in Switzerland as the Schutzhelm 04 (in German) or casque de protection balistique 04 (in French)).
If V is a vector space over a field F, then the cofree coalgebra C (V), of V, is a coalgebra together with a linear map C (V) → V, such that any linear map from a coalgebra X to V factors through a coalgebra homomorphism from X to C (V). In other words, the functor C is right adjoint to the forgetful functor from coalgebras to vector spaces.
A free software Asteroids-like video game played on a vector monitor. Vector-based devices, such as the vector CRT and the pen plotter, directly control a drawing mechanism to produce geometric shapes. Since vector display devices can define a line by dealing with just two points (that is, the coordinates of each end of the line), the device ...
In a classical field theory, the physical states are sections of a Poincaré-equivariant vector bundle over Minkowski space. The equivariance condition means that the group acts on the total space of the vector bundle, and the projection to Minkowski space is an equivariant map. Therefore, the Poincaré group also acts on the space of sections.
