The patent, however, was based on the mutual-inductively coupled or magnetically coupled communication.
The pump works via a drive magnet, 'driving' the pump rotor, which is magnetically coupled to the primary shaft driven by the motor.
The impeller of such a pump is magnetically coupled with the motor, across a separation wall which is resistant to the fluid pumped.
Mechanical illustration of three magnetically coupled oscillating circuits.
The primary and secondary coils are magnetically coupled, creating a dual-tuned resonant air-core transformer.
An alternative means of feeding this system is to use a second coil that is magnetically coupled to the coil attached to the aerial.
The above relationship turns out to be true for any two magnetically coupled circuits.
The gauge sender is usually a magnetically coupled arrangement, with a float arm inside the tank rotating a magnet, which rotates an external gauge.
The General Technics CYA-100 displays true angle of attack via a magnetically coupled vane.
The free piston is magnetically coupled to the passenger modules above.
