Precision dosage apparatus, system and method

A system for controlling delivery dosage, the system comprising:

• a reservoir configured to hold a liquid;
• a delivery device configured to receive the liquid;
• a peristaltic pump configured to pump the liquid from the reservoir to the delivery device;
• a pumping motor mechanically coupled to the peristaltic pump;
• a power terminal configured to provide power to the pumping motor;
• and
• a momentary broke configured to receive a stop signal, momentarily ground the power terminal, and then cease grounding of the power terminal, all in response to the stop signal.

A method for controlling a dosage delivery system, the method comprising:

• activating a pumping motor;
• waiting until a desired dosage is delivered;
• and
• momentarily grounding power to the pumping motor to stop further movement thereof, thereby conserving energy by not continuously grounding power.

An apparatus for delivering a dosage of a liquid, the apparatus comprising:

• a peristaltic pump configured to pump a liquid, the peristaltic pump comprising a pumping motor;
• means for developing a heartbeat signal;
• and
• a watchdog circuit configured to monitor a heartbeat signal and disable the pumping motor in response to irregularities in the heartbeat signal by sending a signal from the watchdog circuit directly to the pumping motor, regardless of commands being received from a control processor.
