Claim Text:
1. An apparatus for detecting a physiological parameter of a user, the apparatus comprising: a housing comprising an optical sensor, a contact surface of the housing configured for placement proximate a targeted area of a user's body; a strap for securing the housing to the targeted area, the optical sensor comprising at least one light source and an optical detector, at least a portion of the optical sensor configured for placement proximate the contact surface; at least one substrate, the light source and the optical detector coupled to an upper surface of the at least one substrate; an opaque member coupled to the upper surface of the substrate and positioned between the light source and the optical detector; and at least one optical barrier positioned between the light source and the optical detector, the at least one optical barrier comprising a laterally extending leg and a vertically extending leg, the laterally extending leg being coupled to the opaque layer and positioned between the light source and the optical detector, the vertically extending leg being substantially perpendicular with respect to the laterally extending leg and extending from the laterally extending leg to a contact portion, the contact surface of the housing comprising the contact portion of the at least one optical barrier.
