Linear velocity sensors measure the linear velocity of an object using either contact or noncontact techniques. Important performance specifications to consider when searching for linear velocity ...

U.S. soldiers prepare for a night mission during operational testing of two new GPS navigation systems. (Nicholas Robertson/Army) The Army’s annual exercise focused on refining its Positioning ...

Vibration sensors are sensors for measuring, displaying, and analyzing linear velocity, displacement and proximity, or acceleration. Vibration — however subtle and unnoticed by human senses — is a ...

Once considered an essential part of the auto industry's high-tech future, lidar sensors are now often seen as optional components with uncertain prospects. The sensors, which use lasers to depict ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...

It is promising but elusive to use covalent organic frameworks (COFs)-based chromatic sensors for chemical tomography – or the 3D spatial mapping of chemical details within living systems.
