Abstract

A transceiver for interfacing with an analyte sensor. The transceiver may include an interface device and a notification device. The interface device may be configured to convey a power signal to the analyte sensor and to receive data signals from the analyte sensor. The notification device may be configured to generate one or more of a vibrational, aural, and visual signal based on one or more data signals received from the analyte sensor. The interface device of the transceiver may receive analyte data from the analyte sensor, and the transceiver may comprise a processor configured to calculate an analyte concentration value based on the received analyte data. The notification device may be configured to generate one or more of aural, visual, or vibrational alarm when the calculated analyte concentration value exceeds or falls below a threshold value.
