    摘要： Improving the accuracy of the flow rate of a valve (10) in a fluidic delivery device in which a desired flow rate may be achieved by varying the duty cycle of the valve. The flow rate of fluid delivery from the valve over its lifetime is stabilized by minimizing the voltage OPENING time of the valve to account for valve and piezoelectric actuator (53) drift. Also, the valve OPENING time of one or more fluidic parameters that impact on the flow rate delivery by the valve and differ among fluidic delivery devices is compensated to optimize the flow rate accuracy.

    摘要： Continuous phase frequency shift keying modulation is employed during wireless transmission from an internal device to an external device to increase robustness of transmissions. The continuous phase frequency shift keying processor receives as input an incoming data stream and includes a timer for toggling its output between a first predetermined frequency and a second predetermined frequency on a predetermined time period basis based on the logical state of each bit in the incoming data stream. For a portion of time while the counter or timer of the CPFSK processor is counting down the predetermined time period associated with the detected logic state of a particular bit of the incoming data signal at least some of the other circuitry, preferably all of the other circuitry of the processor, is toggled to a sleep mode in which power is cut off thereby minimizing power consumption by the processor during this interim state.
