Abstract
The present disclosure relates to noninvasive methods, devices, and systems for measuring various blood constituents or analytes, such as glucose. In an embodiment, a light source comprises LEDs and super-luminescent LEDs. The light source emits light at least wavelengths of about 1610 nm, about 1640 nm, and about 1665 nm. In an embodiment, the detector comprises a plurality of photodetectors arranged in a special geometry comprising one of a substantially linear substantially equal spaced geometry, a substantially linear substantially non-equal spaced geometry, and a substantially grid geometry.

2. A noninvasive optical physiological sensing system comprising:
-
a circular platform forming a housing, the circular platform including a raised edge and a planar surface; at least four detectors arranged on the planar surface of the circular platform, wherein the at least four detectors are arranged in a grid pattern such that a first detector and a second detector are arranged across from each other on opposite sides of a central point along a first axis, and a third detector and a fourth detector are arranged across from each other on opposite sides of the central point along a second axis which is perpendicular to the first axis; and a light permeable cover of the housing. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A noninvasive optical physiological sensing system comprising:
-
a platform forming a housing, the platform including a circular wall protruding from the platform; at least four detectors arranged on the platform and within the circular wall, the at least four detectors spaced apart from each other and configured to output one or more signals responsive to light from one or more light emitters attenuated by body tissue, the one or more signals indicative of a physiological parameter of a wearer of the noninvasive optical physiological sensing system; and a light permeable cover arranged above at least a portion of the housing, the light permeable cover protruding from the circular wall of the platform. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
