Electric power generator for a projectile moving through the air
An electric power generator for a projectile moving through the air is based on vibrational, rather than rotational motion. The electric power generator uses an air stream through, which the projectile is traveling typically 100-250 m/s for mortars to up to 1,500 m/s for sabot or even higher electrically fired rounds. A typical 223 rifle round after being fired has energy of over 1700 J, which is equivalent to 1700 W seconds. If a Nano computer was able to extract energy of for example 50 nanowatts during bullet flight which rarely exceeds two seconds the power needed during the flight would be only a few parts per billion of the bullet's energy. Even allowing for very inefficient extraction of power, the necessary power to operate on onboard electronic devices such as computers and sensors can be extracted from the airstream through which the projectile travels. |

Semiconductor processing tool and methods of operation
A diaphragm position of a valve may be detected and/or determined such that operation of the diaphragm may be monitored. A sensor included in the valve may generate sensor data that may be used to monitor the position of the diaphragm, which in turn may be used to determine a flow of a fluid through the valve.
