    Abstract: Electronic devices may include light sensors. The light sensors may include alignment features. The light sensors may be optically aligned with an aperture in an opaque structure. The opaque structure may be formed from an opaque material or a transparent material with an opaque coating. The light sensor may be mounted in a support structure that has been optically aligned with the aperture. The light sensor or the support structure may include extended portions that are transparent to ultraviolet light. Ultraviolet light may be transmitted through the extended portions to cure adhesive that attaches the light sensor or the support structure to the opaque structure. The light sensor may be optically aligned with the aperture by viewing the aperture through an opening in the support structure, by viewing the alignment features on the light sensor through the aperture or by gathering alignment data using the light sensor during alignment operations.

    Abstract: A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object samples. The apparatus (200) comprises a source light (254) and a reflection optics assembly (264, 268). Signals representative of reflected light are analyzed and data provided to an operator representative of the spectral response characteristics of the object sample (252). The apparatus (200) further comprises a side sensor (276) having a fixed spectral response characteristic for compensating the reflectance measurements in accordance with the light intensity emanating from the lamp. For purposes of calibration, a series of time-sequenced measurements are made of a reference sample. Utilizing these measurements, the apparatus (200) provides computations of compensation coefficients for each spectral segment. The compensation coefficients are utilized, with the side sensor measurements, to provide normalization of the reflectance measurements for each segment and for each measurement within the timed sequence. For each segment, a scale factor is then determined. The scale factors, compensation coefficients and side sensor measurements are employed to compensate actual reflectance measurements, with further compensation provided by a determination of temperature coefficients.

    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.
