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 convey a power signal to the glucose sensor and 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 if a first condition is met, wherein the first condition is the calculated glucose concentration value falling below a hypoglycemic threshold value, and
a vibrational signal having a second pattern different than the first pattern if a second condition is met; and
a communication circuit configured to transmit data to an external device.

2 . The transceiver of claim 1 , wherein the second condition is a power level of the battery falling below a threshold.

3 . The transceiver of claim 1 , wherein the second condition is the transceiver needing a calibration point.

4 . The transceiver of claim 1 , wherein the second condition is the calculated glucose concentration value exceeding a hyperglycemic threshold value.

5 . The transceiver of claim 1 , wherein the interface device comprises an antenna configured to wirelessly convey the power signal to an antenna of the glucose sensor and to wirelessly receive the data signals from the antenna of the glucose sensor.

6 . The transceiver of claim 5 , wherein the notification device is further configured to generate one or more of a vibrational, aural, and visual signal based on how well the glucose sensor and the transceiver are coupled.

7 . The transceiver of claim 1 , wherein the interface device comprises a wired connection to the glucose sensor through a transdermal needle tip.

8 . The transceiver of claim 1 , wherein the external device is a smartphone.

9 . The transceiver of claim 1 , wherein the communication circuit comprises a wireless communication circuit configured to wirelessly transmit the data to the external device.

10 . The transceiver of claim 1 , wherein the notification device is further configured to emit an aural alarm when the calculated analyte concentration value exceeds or falls below a threshold value.

11 . The transceiver of claim 1 , wherein the external device is configured to generate a vibrational signal.

12 . The transceiver of claim 1 , wherein the notification device further includes one or more LEDs configured to generate one or more visual signals.

13 . The transceiver of claim 1 , further comprising a temperature sensor.

17 . A transceiver for interfacing with a glucose sensor, the transceiver comprising:
an interface device configured to convey a power signal to the glucose sensor and to receive data signals from the glucose sensor; a battery; a notification device including a vibration motor; a processor configured to:
calculate an analyte concentration value based on one or more of the received data signals from the glucose sensor,
control the notification device to generate a vibrational signal having a first pattern if a first condition is met, wherein the first condition is the calculated analyte concentration value falling below a hypoglycemic threshold value, and
control the notification device to generate a vibrational signal having a second pattern if a second condition is met; and
a communication circuit configured to transmit data to an external device.

18 . The transceiver of claim 17 , wherein the second condition is a power level of the battery falling below a threshold.

19 . The transceiver of claim 17 , wherein the second condition is the transceiver needing a calibration point.

20 . The transceiver of claim 17 , wherein second condition is the calculated glucose concentration value exceeding a hyperglycemic threshold value.

21 . The transceiver of claim 17 , wherein the interface device comprises an antenna configured to wirelessly convey the power signal to an antenna of the glucose sensor and to wirelessly receive the data signals from the antenna of the glucose sensor.

22 . The transceiver of claim 21 , wherein the processor is further configured to control the notification device to generate one or more of a vibrational, aural, and visual signal based on how well the glucose sensor and the transceiver are coupled.

23 . The transceiver of claim 17 , wherein the interface device comprises a wired connection to the glucose sensor through a transdermal needle tip.

24 . The transceiver of claim 17 , wherein the external device is a smartphone.
