Abstract: An optical sensor system and method of manufacture thereof can include: providing a sensor body; mounting a light emitter to the sensor body, the light emitter for emitting light into tissue; mounting a light detector to the sensor body for providing a physiological measurement from within the tissue; and affixing an optical film above the light detector, the light being angularly constrained by the optical film.

Abstract: A gesture detection device that includes an angled optical lens is disclosed. In one or more implementations, the gesture detection device includes a gesture sensor configured to detect electromagnetic radiation occurring within a limited spectrum of wavelengths and provides one or more signals in response thereto. The gesture detection device also includes an illumination source assembly configured to emit the electromagnetic radiation occurring within the limited spectrum of wavelengths. The illumination source assembly includes an illumination source for emitting the electromagnetic radiation occurring within the limited spectrum of wavelengths and a light collimating structure configured to at least partially collimate the electromagnetic radiation occurring within the limited spectrum of wavelengths. The light collimating structure is oriented at an angle with respect to an axis perpendicular to a surface of the gesture detection device.

Abstract: A gesture sensing device having a single illumination source is disclosed. In one or more implementations, the gesture sensing device includes a single illumination source configured to emit light and a light sensor assembly configured to detect the light reflected from an object and to output time dependent signals in response thereto. The gesture sensing device also includes a processing circuit coupled to the light sensor assembly and configured to analyze the time dependent signals received from the light sensor assembly to determine object directional movement proximate to the light sensor assembly.
