Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

Abstract: An intelligent stylus is disclosed. The stylus can provide a stylus condition in addition to a touch input. The stylus architecture can include multiple sensors to sense information indicative of the stylus condition, a microcontroller to determine the stylus condition based on the sensed information, and a transmitter to transmit the determined condition to a corresponding touch sensitive device so as to cause some action based on the condition.

Abstract: An electronic device may have a housing in which a display is mounted. The display may have an active area in which images are displayed by an array of pixels and an inactive area that is free of pixels. A color ambient light sensor may make color and luminance measurements on ambient light received through an ambient light sensor window in the inactive area of the display or elsewhere in the electronic device. The color ambient light sensor may have color ambient light sensor elements of different colors. The ambient light sensor elements may extend in a row along an edge of the display or may have other configurations. Analog-to-digital converter circuitry and switching circuitry may gather color ambient light sensor measurements and measurements indicative of whether or not the color ambient light sensor has been obscured by an external object from the light sensor elements.

Abstract: An ambient light sensor that is operable in high gain mode and low gain mode is provided. The high gain mode may help provide satisfactory sensitivity at low light levels but may generate saturated output levels in bright ambient lighting conditions. Low gain mode may therefore be switched into use when bright ambient lighting conditions are detected. The ambient light sensor may be placed in high gain mode by default. An auto-gain switch controller may detect whether the ambient light reading is saturated during as given period of time. In response to determining that the ambient light reading is saturated for a programmable number of consecutive time periods, the auto-gain switch controller may reset and switch the ambient light sensor to the low gain mode. The gain state may optionally be embedded into the ambient light sensor output.

Abstract: Electronic devices may include light sensors. A light sensor may be an ambient light sensor that is mounted adjacent to an aperture in an opaque structure. An ambient light sensor may include active light sensor elements located adjacent to the aperture and inactive light sensor elements located adjacent to the opaque structure. Signal processing circuitry may be interposed between the light sensor elements and a summing circuit that sums light signals from the light sensor elements to form an ambient light signal. The signal processing circuitry may include a switch and an amplifier associated with each light sensor element. The switch associated with each element may be used to selectively activate or inactivate that element. The amplifier associated with each element may be used to amplify the light signal from that element by a gain factor that depends on the location of that element with respect to the aperture.

Abstract: An electronic device may be provided that has a display. The display may produce light using a backlight unit or using an array of light-emitting display pixels. An ambient light sensor may be mounted under an active area of the display to measure ambient light that is transmitted through the display. The display may be periodically disabled to prevent the display from producing light that interferes with the ambient light sensor. Display pixels may be coupled to a common cathode switch that can be periodically opened or the backlight in a display with a backlight can be periodically turned off. Control circuitry for periodically disabling the display while enabling the ambient light sensor may be implemented using a display driver integrated circuit mounted to a display.

Abstract: Devices, methods and graphical user interfaces for manipulating user interfaces based on fingerprint sensor inputs are provided. While a display of an electronic device with a fingerprint sensor displays a first user interface, the device may detect movement of a fingerprint on the fingerprint sensor. In accordance with a determination that the movement of the fingerprint is in a first direction, the device allows navigating through the first user interface, and in accordance with a determination that the movement of the fingerprint is in a second direction different from the first direction, the device allows displaying a second user interface different from the first user interface on the display.
