Abstract
Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are provided. The data can be displayed on a hand-held display device having a display such as a key fob device including a user interface, such as an LCD and one or more buttons that allows a user to view data, and a physical connector, such as USB port.
Claims19
A method for transmitting data between a first communication device associated with an analyte sensor and one or more second communication devices configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- establishing a communication channel only with a primary device of a one or more second communication devices during a first time period within a communication window;
- and
- establishing a communication channel with one or more secondary devices of the one or more second communication devices only during a second time period different from the first time period.
A method for synchronizing a time for transmitting data between a first communication device associated with an analyte sensor and a primary communication device and a secondary communication device configured to provide user access to analyte values and/or information derived from analyte values, the method comprising:
- receiving a beacon from a first communication device at a primary communication device during a transmission time window defined by the first communication device;
- establishing a first communication channel between the primary communication device and a secondary communication device;
- transmitting beacon information from the primary communication device to the secondary communication device, wherein the beacon information comprises timing information for establishing a communication channel with the first communication device;
- and
- establishing a communication channel between the first communication device and the secondary communication device based on the beacon information.
A method for processing data from an analyte sensor and transmitting data between a first communication device associated with an analyte sensor and a second communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- activating an analyte sensor data processing circuit and deactivating a transceiver of a first communication device associated with an analyte sensor during a first time interval;
- obtaining and processing analyte sensor data during the first time interval;
- deactivating the analyte sensor data processing circuit and activating the transceiver of the first communication device during a different second time interval;
- and
- transmitting analyte sensor data to the second communication device during the second time interval.
A method for processing data from an analyte sensor, comprising:
- obtaining and processing analyte sensor data using an analyte sensor data device associated with an analyte sensor during a first time interval;
- opening a transmission time window to accept requests for establishing a communication channel to communicate to the analyte sensor data device during a different second time interval, wherein the first time interval and the second time interval do not overlap.
A method for providing analyte sensor measurements from a first communication device associated with an analyte sensor to a second communication device configured to provide user access to analyte values and/or information derived from analyte values, the method comprising:
- receiving, from the first communication device, a request from a second communication device for previous analyte sensor measurements in addition to analyte sensor measurements of a scheduled analyte sensor measurement transmission;
- and
- transmitting to the second communication device from the first communication device a data set of analyte sensor measurements corresponding to a pre-determined time interval that includes the requested previous analyte sensor measurements.
