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.

Abstract: The present disclosure is directed to an apparatus and method of batch assembly. The apparatus for batch assembly may include a plurality of spring units, a plurality of handling units, and a control unit. The method of batch assembly may include aligning an array of devices with a plurality of handling units, attaching the array of devices onto the handling units, expanding the handling units so as to expand the array of devices from a first area to a second area, and transferring the array of devices to a destination.
