Abstract:
1. A method for minimizing the effects of motion artifact on sensor readings taken during continuous transdermal monitoring of a body part in motion, the method comprising: monitoring, with a processor, an output signal from an accelerometer, wherein the output signal indicates acceleration and deceleration of the body part of a user as the body part is in motion translating continuously between a rearward most point and a forward most point relative to the user; determining, with the processor, from the output signal that the body part of the user has decelerated to a predetermined minimum before becoming momentarily stationary to begin acceleration; based on the determination that the body part of the user has decelerated to the predetermined minimum, determining, with the processor, a reading from a pulse oximeter, wherein determining the reading from the pulse oximeter occurs over a time window that includes the body part of the user becoming momentarily stationary and comprises:
