1. An injection pen device for administering medicine, comprising:
a dispensing mechanism configured to dispense medicine;
an encoder configured to generate an analog output signal in response to the dispensing mechanism dispensing the medicine; and
a processor in communication with a memory, the memory storing a force pattern sequence module, which when executed by the processor applies an algorithm that forces at least one edge of the analog output signal generated by the encoder to conform to a pattern consistent with a forward direction of movement to determine a quantity of medicine dispensed by the dispensing mechanism.
