An electronic device can include a housing defining an aperture and at least partially defining an internal volume of the electronic device, an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the internal volume, and an optical component disposed in the aperture. The optical component can include a first and second transparent portions disposed above the electromagnetic radiation detector and the electromagnetic radiation emitter, and an opaque portion disposed between the first and second transparent portions and extending a thickness of the optical component. The first transparent portion, the second transparent portion, and the opaque portion can define a flush exterior surface of the electronic device.

Opaque splits embedded in transparent media for optical emitter/detector isolation

An electronic device can include a housing defining an aperture and at least partially defining an internal volume of the electronic device, an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the internal volume, and an optical component disposed in the aperture. The optical component can include a first and second transparent portions disposed above the electromagnetic radiation detector and the electromagnetic radiation emitter, and an opaque portion disposed between the first and second transparent portions. A conductive component can be in electrical communication with the opaque portion and one or more components of the electronic device.

A wearable device is described. The wearable device includes a housing having a back cover, and an optical mask on first portions of the back cover. The back cover includes a set of windows, with a first subset of windows in the set of windows being defined by an absence of the optical mask on second portions of the back cover, and a second subset of windows in the set of windows being inset in a set of openings in the back cover. An optical barrier surrounds each window in the second subset of windows. A set of light emitters is configured to emit light through at least some of the windows in the set of windows. A set of light detectors is configured to receive light through at least some of the windows in the set of windows.

Physiological monitoring system for measuring oxygen saturation

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.

Multiple light paths architecture and obscuration methods for signal and perfusion index optimization

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.

Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

An optical sensor can be multiplexed for different clients/features including estimating information or characteristics of a user's physiological signals. Additionally, the clients/features can include estimating information or characteristics independent from a user's physiological signals. As the number of clients increase and/or as the requirements for the clients increase, flexibility can be provided to accommodate the various clients. Parallelization of the optical sensor can be used to improve performance as the number of clients increase. For example, the hardware and software architecture can assemble patterns of time slots that measure all desired light paths for the multiple clients and distribute the corresponding measurements to each client according to the client requests. In some examples, the scanning sequence can be represented by frames including slots associated with multiple clients to compress the representation for larger or more complex scan sequences.

System and method for multiplexing an optical sensor

Pre-stored no-touch or no-hover (no-event) sensor output values can initially be used when a sensor panel subsystem is first booted up to establish an initial baseline of sensor output values unaffected by fingers or other objects touching or hovering over the sensor panel during boot-up. This initial baseline can then be normalized so that each sensor generates the same output value for a given amount of touch or hover, providing a uniform response across the sensor panel and enabling subsequent touch or hover events to be more easily detected. After the initial normalization process is complete, the pre-stored baseline can be discarded in favor of a newly captured no-event baseline that may be more accurate than the pre-stored baseline due to temperature or other variations.

Storing baseline information in EEPROM

A touch surface device having improved sensitivity and dynamic range is disclosed. In one embodiment, the touch surface device includes a touch-sensitive panel having at least one sense node for providing an output signal indicative of a touch or no-touch condition on the panel; a compensation circuit, coupled to the at least one sense node, for generating a compensation signal that when summed with the output signal removes an undesired portion of the output signal so as to generated a compensated output signal; and an amplifier having an inverting input coupled to the output of the compensation circuit and a non-inverting input coupled to a known reference voltage.
