摘要： An electronic device can include a housing defining an aperture, and an electromagnetic radiation emitter (1760, 1762, 1764) and an electromagnetic radiation detector (1770) disposed in the housing. An optical component (1711) can be disposed in the aperture and can include a first region (1720, 1722) of a first material having a first index of refraction, the first region aligned with the electromagnetic radiation emitter, a second region (1724) of the first material, the second region aligned with the electromagnetic radiation detector, and a bulk region (1730) surrounding a periphery of the first region and a periphery of the second region, the bulk region including a second material having a second index of refraction that is lower than the first index of refraction.

摘要： Robust estimation of temperatures inside and outside a device can be achieved using one or more absolute temperature sensors optionally in conjunction with thermopile heat flux sensors. Thermopile temperature sensing systems can measure a temperature gradient across two locations within the device, to estimate absolute temperature at locations that are impractical to measure using absolute temperature sensors. Using heat flux models associated with the device, the thermopile temperature sensing system can be used to estimate temperature associated with objects that contact an outer surface of the device, such as a user's skin temperature. Additionally, the thermopile temperature sensing system can be used to estimate ambient air temperature. Within a device, temperature measurements from the thermopile temperature sensors can be used to compensate sensor measurements, such as when the accuracy or reliability of a sensor varies with temperature.
