Abstract

Methods, systems, and devices for short-range low-power wireless communication of analyte information are provided. In some implementations, short-range low-power wireless communication of analyte information may include receiving an electromagnetic wireless communication signal and harvesting energy from the electromagnetic wireless communication signal. In some implementations, short-range low-power wireless communication of analyte information may include enabling capabilities associated with an external sensor in response to detecting the external sensor. In some implementations, short-range low-power wireless communication of analyte information may include detecting an analyte sample; determining an analyte concentration associated with the detected analyte sample; and transmitting an indication of the analyte concentration to an external device.

Claims

1. An apparatus, comprising:

a housing;

a memory unit configured to store computer executable instructions;

a monitor adapted to analyze fluid on a test strip;

a transceiver; and

a processor configured to execute the computer executable instructions stored in the memory unit to;

enable a sensor interface and search for an external sensor with the sensor interface while user interface (UI) capabilities of the apparatus associated with the sensor interface are disabled, the search for the external sensor includes transmission of a signal over a determined period of time,

in response to not detecting the external sensor within the determined period of time, terminate transmission of the signal and disable the enabled sensor interface, and

in response to detecting the external sensor, enable the disabled UI capabilities associated with the sensor interface, activate the external sensor, and determine an analyte concentration from sample information received from the external sensor over the sensor interface.

2. The apparatus of claim 1, wherein the transceiver is configured to perform short-range low-power wireless communication, and the processor is configured to search for the external sensor via short-range low-power wireless communication.

3. The apparatus of claim 2, wherein the short-range low-power wireless communication includes a near field communication protocol or a radio frequency identification protocol.

5. The apparatus of claim 1, wherein capabilities associated with the monitor adapted to analyze the fluid on the test strip are enabled while the UI capabilities associated with the external sensor are disabled.

6. A method comprising:

enabling a sensor interface of an apparatus, wherein the apparatus comprises a monitor adapted to analyze fluid on a test strip;

searching for an external sensor with the sensor interface while user interface (UT) capabilities of the apparatus associated with the sensor interface are disabled, the searching for the external sensor includes transmitting a signal for a determined period of time;

in response to not detecting the external sensor within the determined period of time, terminating the signal being transmitted and disabling the enabled sensor interface; and

in response to detecting the external sensor, enabling the disabled UI capabilities associated with the sensor interface, activating the external sensor, and determining an analyte concentration from sample information received from the external sensor over the sensor interface.

7. The method of claim 6, wherein searching for the external sensor includes using short-range low-power wireless communication.

8. The method of claim 7, wherein using short-range low-power wireless communication includes using a near field communication protocol or a radio frequency identification protocol.
