Abstract

Techniques for system-based motion detection is described, including a first accelerometer configured to detect a first acceleration associated with a system element, a second accelerometer configured to detect a second acceleration associated with the system, and a differential amplifier configured to generate a signal corresponding to the first acceleration, wherein the signal is used to distinguish the first acceleration from the second acceleration.

Claims

1. A system, comprising:

a first element configured to generate an output signal representative of an acceleration applied to the first element;

a coupling element configured to couple the first element to a system element;

a second element configured to generate another output signal representative of another acceleration applied to the second element; and

a mounting element to which the first element and the second element are coupled, the mounting element coupled to the system.

2. The system of claim 1, wherein the first element is an accelerometer coupled to a system element.

3. The system of claim 1, wherein the first element is configured to detect the acceleration associated with the system element.

4. The system of claim 1, wherein the second element is coupled to the system.

5. The system of claim 1, wherein the second element is configured to detect the another acceleration, the another acceleration being associated with the system.

6. The system of claim 1, wherein the acceleration is associated with a pulse.

7. The system of claim 1, wherein the acceleration is associated with a heart rate.

8. The system of claim 1, wherein the acceleration is associated with speech.

9. A system, comprising:

a first accelerometer configured to detect a first acceleration associated with a system element;

a second accelerometer configured to detect a second acceleration associated with the system; and

a differential amplifier configured to generate a signal corresponding to the first acceleration, wherein the signal is used to distinguish the first acceleration from the second acceleration.

10. A system, comprising:

an accelerometer configured to detect an acceleration, the accelerometer being coupled to a system element;

another accelerometer configured to detect another acceleration associated with the system; and

a differential amplifier configured to generate a signal corresponding to the acceleration, wherein the differential amplifier is configured to determine a difference between the acceleration and the another acceleration.

11. The system of claim 10, further comprising a matched coupling system configured to determine the difference between the acceleration and the another acceleration.

12. The system of claim 10, further comprising a coupling system configured to couple the accelerometer to the system element.
