Abstract: Methods and apparatuses for calculating and transmitting medication dosage or bolus information are provided. A blood glucose meter receives a test strip with a sample of the user's blood and measures the user's blood glucose level with a sensor. The meter then calculates a bolus amount that is transmitted to a medication infusion pump using a radio frequency transmitter or transceiver. The infusion pump receives the bolus amount data and then delivers a bolus of medication to the user based on the calculated bolus estimate. The meter may also transmit commands to, and be used to remotely control, the infusion pump.

Abstract: A tone synthesizer circuit (10) includes a multi-tap resistor (86) which produces a plurality of discrete voltages at the taps (T1-T16). A switch (88-118) is provided for each of the taps (T1-T16). The tap switches (88-118) are organized into four groups. A second group of switches are organized into two groups with each of the second switch groups having a connection to one of the switches in each of the first groups. A third group of switches (164-170) are each connected to one of the group of the second switches (132-138). Circuitry responsive to a digital clock input signal produces a group of control signals on control lines (66-72) which are respectively connected to operate each of the four groups of the first switches (88-108). Further circuit means responsive to the digital input signal transmit control signals through control lines (74-76) to operate the second group of switches (132-138).
