摘要：
A method of using a sensor comprising the steps of: sensing a condition; transmitting a binary signal having either a first state or a second state indicative of the sensed condition; determining either a first or a second mode of operation of a prime mover to be in effect; operating the prime mover, in the first mode of operation, responsive to the first or second state of the binary signal; and operating the prime mover, in the second mode of operation, responsive to the rate of transition of the binary signal between the first and second states.
