MOTION COMPENSATED BIOMEDICAL SENSING
First Claim
1. A biomedical sensing system comprising:
- a diagnostic sensor configured to sense a physiological metric of a living subject via a contact with the living subject, and to generate a diagnostic signal corresponding to the physiological metric;
a motion sensor situated proximate the diagnostic sensor, the motion sensor configured to sense a motion corresponding to a motion of the diagnostic sensor during a sensing of the physiological metric by the diagnostic sensor, and to generate a motion signal corresponding to the sensed motion;
an analysis unit including;
a memory storing a motion correction module; and
a processor configured to receive the diagnostic signal and the motion signal, and to execute the motion correction module from the memory to adaptively filter the diagnostic signal using the motion signal to produce a motion compensated diagnostic signal.

Abstract
There is provided a biomedical sensing system and a method for its use. Such a system includes a diagnostic sensor configured to sense a physiological metric of a living subject via contact with the living subject, and to generate a diagnostic signal corresponding to the physiological metric. In addition, the system includes a motion sensor situated proximate the diagnostic sensor and configured to sense a motion corresponding to a motion of the diagnostic sensor during sensing of the physiological metric. The system also includes an analysis unit including a processor, and a memory storing a motion correction module. The processor is configured to receive the diagnostic signal and the motion signal, and to execute the motion correction module from the memory to adaptively filter the diagnostic signal using the motion signal to produce a motion compensated diagnostic signal.

16. A method for use by a biomedical sensing system including a diagnostic sensor, a motion sensor, and an analysis unit having a processor and a memory, the method comprising:
-
sensing, using the diagnostic sensor in contact with a living subject, a physiological metric of the living subject; generating, using the diagnostic sensor, a diagnostic signal corresponding to the physiological metric; sensing, using the motion sensor, a motion corresponding to a motion of the diagnostic sensor during the sensing of the physiological metric by the diagnostic sensor; generating, using the motion sensor, a motion signal corresponding to the sensed motion; and adaptively filtering the diagnostic signal using the motion signal to correct for the motion of the diagnostic sensor during the sensing of the physiological metric, to produce a motion compensated diagnostic signal. - View Dependent Claims (17, 18, 19, 20)
