SYSTEM AND METHODS FOR PHYSIOLOGICAL MONITORING
First Claim
1. A monitoring device, comprising:
- at least one sensor configured to monitor one or more physiological parameters of a subject, wherein the sensor comprises a plurality of radiation sources and detectors disposed on a flexible substrate in a designated physical arrangement;
a processing unit operatively coupled to the sensor, herein the processing unit is configured to dynamically configure an operational geometry of the sensor by controlling the intensity of one or more of the radiation sources and the gain of one or more of the detectors so as to satisfy at least one quality metric associated with one or more physiological parameters of the subject.

Abstract
Embodiments of devices, methods, and non-transitory computer readable media for monitoring a subject are presented. The monitoring device includes at least one sensor configured to monitor one or more physiological parameters of a subject and a processing unit operatively coupled to the sensor. The sensor comprises a plurality of radiation sources and detectors disposed on a flexible substrate in a designated physical arrangement. The processing unit is configured to dynamically configure an operational geometry of the sensor by controlling the intensity of one or more of the radiation sources and the gain of one or more of the detectors so as to satisfy at least one quality metric associated with one or more physiological parameters of the subject.

26. A method for monitoring a subject, comprising:
-
selecting an initial set of one or more radiation sources and one or more detectors for a particular wavelength from a plurality of radiation sources and detectors disposed on a flexible substrate in a sensor in a designated physical arrangement; determining an initial value of one or more physiological parameters of a subject by evaluating a region of interest of the subject using the initial set of radiation sources and detectors; estimating a quality metric associated with the initial value of the physiological parameters; and dynamically configuring the operational geometry of the sensor by controlling intensity of one or more of the radiation sources, gain of one or more of the detectors, or a combination thereof, to satisfy at least one quality metric associated with one or more physiological parameters of the subject. - View Dependent Claims (27, 28, 29)
