Systems and methods for monitoring physiological parameters
First Claim
1. An apparatus for detecting a physiological parameter of a user, the apparatus comprising:
- a housing comprising an optical sensor and at least one circuit board coupled to the optical sensor, a portion of the housing configured for placement proximate a user'"'"'s wrist;
an attachment mechanism for securing the housing to the user'"'"'s wrist,the optical sensor comprising at least one light source and at least one optical detector, the optical sensor configured for placement adjacent the user'"'"'s wrist, at least a portion of the optical sensor extending a protrusion distance beyond the portion of the housing toward the user'"'"'s wrist,wherein the protrusion distance is adjustable, andwherein the optical sensor portion is threadedly mated with the base portion such that rotation of the optical sensor portion in a first direction increases the protrusion distance and rotation of the optical sensor portion in a second direction decreases the protrusion distance, and wherein rotation of the optical sensor portion causes rotation of at least a portion of the at least one circuit board.

Abstract
Described herein are systems and methods for mounting optical sensors in physiological monitoring devices worn by a user to sense, measure, and/or display physiological information. Optical sensors may be mounted in the rear face of the device, emit light proximate a targeted area of a user'"'"'s body, and detect light reflected from the targeted area. The optical sensor may be mounted in a housing or caseback such that at least a portion of the optical sensor protrudes a distance from at least a portion of the housing. The protrusion distance may be adjustable such that a user may achieve a customized fit of the wearable device. Adjustment of the protrusion distance may also result in a customized level of contact and/or pressure between the optical sensor and the targeted area which may, in turn, result in more reliable and accurate sensing of physiological information.

15. An apparatus for monitoring a physiological parameter of a user, the apparatus comprising:
-
a base portion; an annular portion; and a central portion comprising an optical sensor and a first planar extension of a circuit board, the optical sensor configured for placement proximate a user'"'"'s wrist, wherein a height of the central portion relative to the base portion is adjustable based, at least in part, on a rotation of the annular portion, and wherein the rotation of the annular portion adjusts a distance between the first planar extension of the circuit board and a second planar extension of the circuit board. - View Dependent Claims (16, 17, 18, 19)
