    Abstract: An electronic device such as an earbud may have control circuitry mounted in a housing. The housing may have portions such as an ear portion with a speaker port through which a speaker plays audio and a stalk portion that extends from the ear portion. Proximity sensors may be formed in the electronic device. For example, one or more proximity sensors may be formed on the ear portion to detect when a user has inserted an earbud into the ear of the user and/or one or more proximity sensors may be formed on a stalk portion to detect when a user is holding an earbud by the stalk or when a user is providing finger touch input such as taps, swipes, and/or other gestures on the stalk portion. The proximity sensors may be optical proximity sensors such as coherent self-mixing proximity sensors.

    Abstract: Aspects of the subject technology relate to an apparatus for self-mixing particulate-matter sensing using a vertical-cavity surface-emitting laser (VCSEL) with extrinsic photodiodes. The apparatus includes a dual-emitting light source disposed on a first chip and to generate a first light beam and a second light beam. The first light beam illuminates a particulate matter (PM), and a light detector extrinsic to the first chip measures the second light beam and variations of the second light beam and generates a self-mixing signal. The variations of the second light beam are caused by a back-scattered light resulting from back-scattering of the first light beam from the PM. The light detector is coupled to the dual-emitting light source. The direction of the second light beam is opposite to the direction of the first light beam, and the second light beam is directed to a sensitive area of the light detector.

    Abstract: Techniques are disclosed by which electronic devices that include line-of-sight optical communication systems may become optically aware of other electronic devices and perform optical communication handshakes with other devices. An electronic device may use a motion sensor to record its posing when it determines, during the performance of an optical communication handshake, that it is pointed at the electronic device with which it is performing the optical communication handshake (or that the other electronic device is within a field of view of the electronic device). A recorded device posing, in combination with optical communications and motion sensor data, may also be used to map another device's location and enable a user of an electronic device to pan away from and break optical communication with the other device, then easily return to a recorded posing that enables a continuation of optical communications with the other device.
