Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.

Abstract: An electro-optical device includes a laser light source, which emits at least one beam of light pulses, a beam steering device, which transmits and scans the at least one beam across a target scene, and an array of sensing elements. Each sensing element outputs a signal indicative of a time of incidence of a single photon on the sensing element. Light collection optics image the target scene scanned by the transmitted beam onto the array. Circuitry is coupled to actuate the sensing elements only in a selected region of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.

Abstract: A proximity sensor includes a light source configured to emit a beam of optical radiation and a detector configured to output an electrical signal in response to the optical radiation that is incident on the detector. A first optical multimode fiber is configured to receive the emitted beam and to direct the emitted beam toward an object. A second optical multimode fiber is configured to receive the optical radiation reflected from the object and to convey the received optical radiation to the detector. A processor is coupled to process the electrical signal so as to compute a distance to the object.

Abstract: One embodiment may take the form of a method of operating a computing device to provide presence based functionality. The method may include operating the computing device in a reduced power state and collecting a first set of data from a first sensor. Based on the first set of data, the computing device determines if an object is within a threshold distance of the computing device and, if the object is within the threshold distance, the device activates a secondary sensor to collect a second set of data. Based on the second set of data, the device determines if the object is a person. If the object is a person, the device determines a position of the person relative to the computing device and executes a change of state in the computing device based on the position of the person relative to the computing device. If the object is not a person, the computing device remains in a reduced power state.

Abstract: An electro-optical device includes at least one laser light source and a beam steering device, which transmits and scan the at least one beam across a target scene. One or more sensing elements output a signal indicative of a time of incidence of a single photon on the sensing element from the target scene. Circuitry processes the signal in order to determine respective distances to points in the scene and controls the light source to emit the beam at the low level during a first scan, to identify, based on the first scan, the points in the scene that are located at respective distances from the device that are greater than a predefined threshold distance, and to control the laser light source during a second scan to emit the beam at the high level while the beam steering device directs the beam toward the identified points.

Abstract: A sensing device includes an array of sensing elements. Each sensing element includes a photodiode, including a p-n junction, and a local biasing circuit, coupled to reverse-bias the p-n junction at a bias voltage greater than a breakdown voltage of the p-n junction by a margin sufficient so that a single photon incident on the p-n junction triggers an avalanche pulse output from the sensing element. A bias control circuit is coupled to set the bias voltage in different ones of the sensing elements to different, respective values that are greater than the breakdown voltage.

Abstract: An electronic device may have light-based components. The light-based components may include light sources, light detectors, and image sensors. The light-based components may be aligned with a window in the device. The window may be formed within an inactive area of a display or within other device structures. The window may have one or more window members mounted within an opening in a display layer in the inactive area. Visible light blocking material such as chalcogenide glass may be incorporated into the window to provide the window with an opaque appearance that matches the opaque appearance of surrounding portions of the inactive portion of the display. In configurations in which the light-based components include a visible image sensor or other visible light detecting component, the window may be provided with a portion that is transparent at visible wavelengths.
