Apparatus and associated methods relate to an airfoil configured to be disposed at a distal end of a tank. In an illustrative example, the airfoil may be configured such that, when the tank travels at
Apparatus and associated methods relate to modulating a duty cycle in each of N interleaved power stages in response to determination whether a phase current is above or below an average of all phase output
Apparatus and associated methods relate to a hand-tied hair weft having at least two hair bundles fixed to three or more thread-like filaments that provide a cortex, where each two adjacent hair bundles are separated
Apparatus and associated methods relate to a safety control system having a processor that (1) automatically interrogates a portable data storage device, (2) determines whether a configuration profile of the safety control system matches a
