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.

First claim

What is claimed is:

1. A transceiver for interfacing with a glucose sensor, the transceiver comprising:
an interface device configured to receive data signals from the glucose sensor;
a battery;
a processor configured to calculate a glucose concentration value based on one or more of the received data signals from the glucose sensor;
a notification device including a vibration motor, wherein the notification device is configured to generate:
a vibrational signal having a first pattern, and
a vibrational signal having a second pattern different than the first pattern; and

a communication circuit configured to transmit data to an external device;
wherein the transceiver is configured to determine whether a first condition is met, cause the notification device to generate the vibrational signal having the first pattern if the first condition is met, determine whether a second condition is met, and cause the notification device to generate the vibrational signal having the second pattern if the second condition is met;
wherein the first condition is the calculated glucose concentration value falling below a hypoglycemic threshold value, and the second condition is for prompting a user to input a calibration point.
