An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle avoidance and distance measurement systems. The ultrasonic range finder measures the distance by emitting a 40KHz pulse of ultrasonic sound that travels through the air until it...
What are the characteristics that make a good electron tube? I understand that the purpose of an "electron tube" is to act as an amplifier or an electronic switching component for high power systems, but what is the ideal composition of one? Schematically they are comprised of a cathode, a grid...
Since the site rejected my disclosure of that explanation of an innovative approach to energy conservation; I won't use this site for any purposes other than the usual SCOTUS.
