First Claim
1. A physiological monitoring system comprising:
- a sensor, comprising;
a light source; and
a photodetector capable of detecting light from said light source after attenuation by tissue of a measurement site; and
a device coupled to the sensor, comprising;
one or more accelerometers; and
a signal processor which receives a signal generated by the one or more accelerometers, said signal processor capable of;
generating a movement signal based on the signal generated by ‘
the one or more accelerometers; and
providing feedback to a user based on the movement signal for the device.

Abstract
The present disclosure relates to methods, devices, and systems for measuring a blood analyte, such as glucose. The disclosure relates more specifically to the use in such methods, devices, and systems of one or more accelerometers to aid in the collection of data, operation of the device, filtering, and other uses. In some embodiments, the accelerometers are three-dimensional accelerometers. An accelerometer can be used in conjunction with analyte monitoring that may be performed with infrared, near infrared, or other wavelength spectroscopy. The accelerometer may allow a monitoring instrument to expect noisy measurement data, indicate positioning of a measurement site for improved expected results, indicate position of the instrument, or help the user properly place or control the instrument. It may also improve analyte monitoring by providing motion information that can be used to help determine and reduce or remove movement-related signal artifacts or noise that may be present within the monitoring signal.
