Abstract: Embodiments of systems and methods for using electronic diffusers to implement message indicators are described. A segment of a diffuser attached to an electronic device is configured to indicate an informational message in response to signals that result in a change to an optical property. A set of information to be displayed using the segment is determined, and a signal is transmitted to the segment to display the information.

Abstract: A head mounted device includes a housing and a set of one or more SMI sensors. The set of one or more SMI sensors are disposed in the housing. The set of one or more SMI sensors are configured to emit electromagnetic radiation toward an anatomical structure adjacent a nasal passageway of a user and generate one or more SMI signals including information about movement of the anatomical structure.

Abstract: This relates to systems and methods for determining one or more physiological signals of a user using ambient light. The systems and methods can include one or more light sensors configured to measure light that has interacted with a user and one or more light sensors configured to measure ambient light. The gain of the one or more light sensors can be adjusted based on the levels of measured ambient light. For example, the gain of the one or more light sensors can be increased when ambient light levels are low (e.g., a low light environment), or the gain of the one or more light sensors can be decreased when ambient light levels are high (e.g., a bright light environment). In some examples, the systems can include a variable opacity element whose transmission properties (e.g., opacity and/or selected one or more wavelengths to pass through) can be varied.

Abstract: Electronic equipment such as a computer tablet stylus, computing equipment, or other electronic devices may be provided with status indicators. A status indicator may be formed from a layer of liquid crystal material interposed between a pair of polarizers. Electrode structures may be used to apply electric fields to the liquid crystal material to place the status indicator in an opaque state or a transparent state. A colored structure or other structure may be placed under the liquid crystal material to allow the status indicator to change between a dark or diffuse to colored appearance. The status indicator may be provided in the shape of a ring that extends around the perimeter of a cylindrical stylus. Multiple status indicators may be grouped in a cluster to serve as an analog gauge. Light guide structures and light sources may provide illumination for the status indicators.

Abstract: A computer or other electronic device including a processor and an input device, such as a track pad. The track pad being in communication with the processor and including a movable surface, a light source in communication with the processor, and an optical sensor in selective optical communication with the light source and in communication with the processor. The optical sensor detects movement of the movable surface by receiving light from the light source.

Abstract: An electronic device may include one or more microphones that monitor ambient noise and generate ambient noise data. The electronic device may include processing circuitry that receives the ambient noise data and compares the ambient noise data to a baseline ambient noise profile to detect changes in the ambient noise. Changes in the ambient noise may be caused by user gestures. The electronic device may compare the changes in the ambient noise to characteristic changes in ambient noise that are associated with user gestures to determine the user gesture made by a user. The processing circuitry may modify the operation of the electronic device based on the user gesture. An ambient noise input device may include surface features or movable components that cause the characteristic changes in the ambient noise. Ambient noise input devices may provide feedback to guide a user to provide input using ambient noise sensing.

Abstract: An input device for computing devices that include touch screens. The input device includes a body, a nib or tip movably coupled to the body, and an actuator operably connected to the body and the nib. The actuator moves the nib from a first position to a second position, and in the first position the input device provides a first input to the computing device and in the second position the input device provides a second input to the computing device.

Abstract: An input device for computing devices that include touch screens. The input device includes an outer housing having an inner surface and an inner shaft. The inner shaft is at least partially received within the outer housing. A nib is operatively coupled to the inner shaft. Providing a first force to the nib causes the inner shaft to contact the inner surface of the outer housing at a first contact point along the outer housing, and providing a second force to the nib causes the inner shaft to contact the inner surface of the outer housing at a second contact point along the outer housing.
