Abstract: An optical sensor assembly is provided. The optical sensor assembly includes a circuit board, an optical sensor positioned on the circuit board, and a front cover attached to the circuit board and covering the optical sensor. The front cover includes an optical element configured to guide or condense an incident light of a predetermined wavelength onto the optical sensor. The front cover is made of polypropylene or polyethylene. The predetermined wavelength is in a range from 8 micrometers to 12 micrometers.

Abstract: There is provided an auto detection system including a thermal detection device and a host. The host controls an indication device to indicate a prompt message or detection results according to a slope variation of voltage values or 2D distribution of temperature values detected by the thermal detection device, wherein the voltage values include the detected voltage of a single pixel or the sum of detected voltages of multiple pixels of a thermal sensor.

Abstract: An earbud with temperature sensing is provided, and the earbud includes a housing, a speaker and a first temperature sensor. The housing defines a first opening and a second opening. The speaker is disposed within the housing and oriented so that audio emitted by the speaker exits the housing through the first opening defined by the housing. The first temperature sensor is positioned along an interior surface of the housing and aligned with the second opening in the housing for non-contact temperature sensing. In response to the earbud being positioned for use within an ear of a user, the second opening aligns with an inner side of the tragus close to the ear canal, the cavum conchae, an inner edge of the antitragus, or the cheek close to the ear, such that the first temperature sensor detects a body temperature of the user through the second opening.
