A rocket is defined as a technologically advanced reaction motor that can carry its oxidant to propel a launch vehicle. A reaction motor is used as a propulsion device to generate a forward push by expelling the rocket structure in a backward direction. A missile is an unmanned rocket vehicle. …

A transducer is any device used to convert energy from one form to another, such as a conversion from mechanical to electrical energy or vice versa. An electroacoustic transducer is a device that converts acoustic energy (sound) into electrical energy (voltage or current) or vice versa.   Piezoelectric materials modify …

Quantum sensors are measuring device that takes advantage of quantum correlations, such as states in a quantum superposition or entanglement, for better sensitivity and resolution than can be obtained by classical systems.  QP will boost the capabilities of all sorts of sensory devices, such as gravimeters, which are used to …
