Abstract

A wrist-worn device monitors movements of a user with a flexible circuit member. The flexible circuit member is fault tolerant. It may contain extra and/or redundant traces as well as the ability to store data on RAM if the flash memory fails or if some or all trace connections between the processor and flash memory fail. Data stored on the RAM may or may not contain less fidelity. Lower fidelity data may be used to alleviate issues arising if the RAM has less storage capacity than the flash memory.

First claim

What is claimed is:

1. A method comprising:
receiving, by a computing device, sensor data generated by a sensor, the sensor data indicating one or more sensed movements of a user;
determining a first remaining memory capacity of RAM of a processor of the computing device;
determining, based on the first remaining memory capacity, that the RAM is approaching a first low capacity condition; and
in response to determining that the first low capacity condition has been satisfied, operating the computing device in a first operational mode.

2. The method of claim 1 , further comprising:
in response to determining that the first low capacity condition has been satisfied, transmitting a signal indicating that the RAM is running low on available memory; and
displaying, on a display device, a communication indicating that the user may synch the computing device with another computing device.

3. The method of claim 1 , wherein operating the computing device in the first operational mode further comprises:
reducing an amount of data stored on the RAM.

4. The method of claim 1 , further comprising:
determining a second remaining memory capacity of the RAM; and
determining, based on the second remaining memory capacity, that the RAM is approaching a second low capacity condition.

5. The method of claim 4 , wherein an amount of available memory on the RAM corresponding to the first low capacity condition is greater than an amount of available memory on the RAM corresponding to the second low capacity condition.

6. The method of claim 1 , in response to determining that a second low capacity condition has been satisfied, operating the computing device in a second operational mode.

7. The method of claim 6 , wherein operating the computing device in a second operational mode further comprises:
modifying a format of the sensor data stored on the RAM.

8. The method of claim 7 , wherein modifying the format of the sensor data further comprises:
adjusting a frequency with which the sensor data is obtained from the sensor.

9. The method of claim 8 , further comprising:
converting, via a software application operated by the computing device, the sensor data back to an original format; and
transmitting the converted sensor data to another computing device.

10. The method of claim 6 , wherein operating the computing device in a second operational mode further comprises:
modifying a frequency with which the computing device may be synched with another computing device.

11. The method of claim 6 , wherein operating the computing device in a second operational mode further comprises:
determining one or more types of data that may not be stored on the RAM while operating in the second operational mode.

12. The method of claim 11 , wherein the one or more types of data comprises at least date information or time information.

13. The method of claim 6 , wherein operating the computing device in a second operational mode further comprises:
determining at least a first type of data that may stored on the RAM while operating in the second operational mode.

14. The method of claim 13 , wherein the first type of data comprises sensor data.

15. A device for monitoring user movements, the device comprising:
a sensor that generates sensor data indicating one or more sensed movements of a user;
one or more processors connected to the sensor and programmed with computer-executable instructions that, when executed by the one or more processor, cause the device to:
receive the sensor data;
determining a first remaining memory capacity of RAM of a processor of the one or more processors;
determining, based on the first remaining memory capacity, that the RAM has reached a low capacity condition; and
in response to determining that the low capacity condition has been reached, operating the device in a first operational mode.

16. The device of claim 15 , wherein the computer-executable instructions, when executed, further cause the device to:
transmit a signal indicating that the low capacity condition has been reached; and
display, on a display device, a communication indicating an amount of available memory.

17. The device of claim 15 , wherein the computer-executable instructions, when executed, further cause the device to: operate in the first operational mode by reducing an amount of data stored on the RAM.

18. The device of claim 15 , wherein the computer-executable instructions, when executed, further cause the device to: operate in the first operational mode by storing sensor data on the RAM for a first time period.

19. The device of claim 15 , wherein the computer-executable instructions, when executed, further cause the device to: operate in the first operational mode by reducing a number of operational functions performed by the device.

20. The device of claim 19 , wherein a first operational function performed by the device comprises transmitting a signal indicating that the device is in a low memory capacity condition.
