Abstract

The present solution provides a system and a method for efficiently transmitting data recorded by a wearable sensor. More particularly, the systems and methods described herein enable the data/context-aware transmission of data. In some implementations, by classifying data into predefined categories and then transmitting the data using a transmitter configuration associated with each of the categories enables improved transmission reliability while also improving battery life.

1. A method for efficiently transmitting data from a wearable device, the method comprising:

classifying, by a wearable device with a transmitter configurable to transmit according to different transmission configurations, a first subset of data obtained by the wearable device into a first category of a plurality of categories, each of the plurality of categories corresponding to one of a plurality of transmission configurations specifying at least a power at which the transmitter is to transmit;

establishing, by the wearable device, the transmitter to use a first transmission configuration corresponding to the first category for transmitting the first subset of data;

transmitting, by the transmitter, the first subset of data using the first transmission configuration;

establishing, by the wearable device responsive to classifying a second subset of data into a second category of the plurality of categories, the transmitter to use a second transmission configuration of the plurality of transmission configurations corresponding to the second category, the second transmission configuration different from the first transmission configuration; and

transmitting, by the transmitter, the second subset of data using the second transmission configuration.

2. The method of claim 1, further comprising transmitting, by the transmitter, to a receiver an indication of one of the first category or the first transmission configuration prior to transmitting the first subset of data.

3. The method of claim 1, further comprising transmitting, by the transmitter, to a receiver an indication of one of the second category or the second transmission configuration prior to transmitting the second subset of data.

4. The method of claim 1, further comprising encoding the first subset of data with a first encoding scheme specified by the first transmission configuration.

5. The method of claim 1, further comprising pausing a predetermined amount of time after transmitting to the receiver the indication of one of the first category or the first transmission configuration.

6. The method of claim 1, further comprising obtaining, by the wearable device, the data from measurements via a motion sensor within the wearable device.

7. The method of claim 1, wherein the first subset of data includes a plurality of data points, and the first subset of data is classified based on the differences between consecutive data points within the plurality of data points.

8. The method of claim 1, wherein each of the plurality of transmission configurations specify at least one of a baud rate, a transmission frequency, a duty cycle of transmission or a receiving filter bandwidth.

9. The method of claim 1, where classifying the first subset of data into the first category is responsive to a context associated with the first subset of data.

10. The method of claim 9, wherein the context is one of an age of a person wearing the wearable device, a time of day during which the first subset of data was captured, or an activity performed by the person wearing the sensor when the first subset of data was obtained.

11. The method of claim 1, wherein establishing the transmitter to use the first transmission configuration comprises selecting the transmitter from a plurality of different transmitters on the wearable device.
