Abstract: Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.

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: In some embodiments, a display stack includes a set of light-emitting elements, and a display backplane that includes a set of conductors and is electrically coupled to the set of light-emitting elements. A conductor in the set of conductors has a length, and a curved edge extending along at least a portion of the length. In some embodiments, a display stack includes a set of light-emitting elements; a set of transistors, electrically coupled to the set of light-emitting elements; and a set of conductors, electrically coupled to the set of transistors. The set of transistors may be electrically coupled to the set of conductors at a set of conductive pads. A plurality of conductive pads in the set of conductive pads is coupled to a single conductor in the set of conductors. The single conductor approaches different conductive pads in the plurality of conductive pads at different angles.

Abstract: A wearable device includes a device housing configured to be worn on a first surface of a user, a set of one or more SMI sensors, and a processor. The set of one or more SMI sensors is mounted within the device housing and configured to emit a set of one or more beams of electromagnetic radiation, with each beam emitted in a different direction extending away from the first surface. The set of one or more SMI sensors is also configured to generate a set of one or more SMI signals containing information about a relationship between the device housing and a second surface. The processor is configured to extract the relationship between the device housing and the second surface from digitized samples of the set of one or more SMI signals.

Abstract: A device includes an electronic display, a cover through which the electronic display projects an image, and an array of SMI sensors. The array of SMI sensors is positioned on a same side of the cover as the electronic display. Each SMI sensor is configured to emit electromagnetic radiation toward a respective portion of: an interior surface of the cover, or a surface of a component of the device attached to the cover; and generate a respective SMI output including information indicative of vibration of the respective portion of the cover or the component. The device also includes circuitry configured to characterize a vibratory waveform impinging on the device. The vibratory waveform is characterized using at least two of the SMI outputs.

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: Disclosed herein are structures, devices, and systems for detecting touch and force inputs at multiple sensing locations on a surface of an electronic device using waveguide-based interferometry. A laser light source, such as a VCSEL, inserts light into a waveguide positioned adjacent to the sensing locations, and an input at a sensing location alters the inserted light in the waveguide allowing for determination of the input's touch or force at the sensing location. Wavelength modulation of the inserted light allows isolation in frequency of the signals from each sensing location. Optical phase locking can be used to lock an absolute distance beat frequency corresponding to a stationary reference point in the waveguide.

Abstract: An electronic device includes an electromagnetic radiation source having an axis, a set of optics disposed about the axis, a reflector disposed about the axis non-symmetrically, and a controller configured to operate the electromagnetic radiation source while controlling a beam steering orientation (e.g., rotation) of the reflector. The reflector is disposed to reflect electromagnetic radiation emitted by the electromagnetic radiation source. The set of optics is disposed to shape electromagnetic radiation emitted by the electromagnetic radiation source and direct electromagnetic radiation received from the reflector into a panoramic field of view about the axis.

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.
