Patent abstract
The invention is directed to a method and circuitry for controlling dosage rates of a treatment solution. An electric pulse is directed through a coil, inducing a magnetic field and causing a valve to open. A subsequent set of pulses is directed through the coil to maintain the position of the valve. Between pulses, the coil motivates current to flow. Energy associated with the current is captured in a collection circuitry. The method and circuitry may also interpret a signal induced in the coil by an externally applied magnetic field such as that produced by an MIR. The method and circuitry may provide an electric signal to counteract the externally applied magnetic field or to produce a degaussing field.
