Abstract: An electronic device such as a portable electronic device may include a single-shot alignment-free spectrometer with no moving parts. The spectrometer may include a diffractive member, such as a grating, an aperture, and an image sensor that generates data in response to incident light. The diffractive member may diffract the incident light based on its wavelength and angle of incidence, and the aperture may further encode the light. The data generated by the image sensor may be used by control circuitry in combination with correlations between spectrometer measurements and known light profiles to determine the wavelength and angle of incidence of the light. These correlations may be determined using a deep neural network. Control circuitry may adjust one or more settings of the electronic device based on the wavelength and angle of incidence, or may use the wavelength and angle of incidence to determine information regarding an external object.

Abstract: The disclosed embodiments of haptic locomotion use one or more actuators to: 1) determine the properties of contact surfaces to improve various applications that use haptic locomotion; 2) automatically improve power transfer efficiency during wireless charging or cellular or wireless signal reception; 3) increase device accessibility for visually or hearing impaired users; 4) improve speaker and microphone performance; 5) protect a free falling mobile device from impact damage by orienting the mobile device to a low-risk orientation during free fall, or by driving the mobile device away from a high-risk orientation during free fall; and 6) control asymmetric surface friction using a directional magnetic field provided by an actuator to improve haptic locomotion in a desired direction of travel.

Abstract: A device operates in pairing mode, indoor navigation mode or search mode. For each mode, a magnetic sensor in the device senses one or more alternating current (AC) magnetic fields emitted by one or more transmitters in a three-dimensional (3D) space, and uses the one or more AC magnetic fields to determine a position of the device relative to the one or more transmitters or another device. In pairing mode, relative position vectors computed from two or more AC magnetic fields allows the device to choose the closest transmitter for pairing. In indoor navigation mode, multiple detections of AC magnetic fields emitted by multiple transmitters assist a user in navigating an indoor space. In search mode, a companion device and a lost device each sense an AC magnetic field from a transmitter, and he AC magnetic fields are used to determine a relative position vector from the companion device to the lost device.

Abstract: An electronic device may include sensors such as a visible-light image sensor for capturing images. The sensors may also include optical sensors that operate at other wavelengths. An infrared light sensor may be used to gather an infrared light spectrum of a target object. The infrared light sensor may have a beam steerer and other adjustable components such as adjustable lenses and adjustable polarizers. During operation, an infrared beam emitted by the infrared light sensor may be steered onto the target object using information from a captured visible-light image and/or other sensor data such as distance sensor data, orientation sensor data, three-dimensional image sensor data, and data from other sensors. Infrared spectra, visible-light camera images, and/or data from other sensors may be used in characterizing target objects so that notifications can be provided to a user and other actions taken.
