Abstract: In various embodiments, methods and systems for implementing integrated free space and surface inputs are provided. An integrated free space and surface input system includes a mixed-input pointing device for interacting and controlling interface objects using free space inputs and surface inputs, trigger buttons, pressure sensors, and haptic feedback associated with the mixed-input pointing device. Free space movement data and surface movement data are tracked and determined for the mixed-input pointing device. An interface input is detected for the mixed-input pointing device transitioning from a first input to a second input, such as, from a free space input to a surface input or from the surface input to the free space input. The interface input is processed based on accessing the free space movement data and the surface movement data. An output for the interface input is communicated from the mixed-input pointing device to interact and control an interface.

Abstract: Examples of mixed reality computing devices that utilize remote sensors and local sensors as input devices are disclosed. In one example, a mixed reality computing device comprises an image sensor, a remote input device, a processor, and storage comprising stored instructions. The stored instructions are executable by the processor to perform object motion tracking and environmental tracking based on output from the image sensor, and in response to detecting that the remote input device is in use, adjust a parameter of the motion tracking while maintaining the environmental tracking.

Abstract: An enhanced parallel protection circuit is provided. A system using separate battery packs in a parallel configuration is arranged with multiple protection circuit modules (PCMs). The PCMs are configured to detect fault conditions, such as over voltage, under voltage, excess current, excess heat, etc. Individual PCMs can be configured to control associated switches and/or other components. When a fault condition is detected by an individual PCM, the individual PCM triggers one or more associated switches to shut down one or more components. In addition, by the use of the techniques disclosed herein, the individual PCM can also trigger switches that are controlled by other PCMs. Configurations disclosed herein mitigate occurrences where a multi-PCM device is operating after at least one PCM has shut down. Configurations disclosed herein provide safeguards and redundant protection in scenarios where a fault event is detected by one PCM and not detected by another PCM in a parallel configuration.

Abstract: Embodiments related to outputting spatial audio via a portable computing device are presented. For example, one disclosed embodiment provides a portable computing device for wirelessly detecting a presence of a remote speaker external to the portable computing device, determining a location of the remote speaker, and establishing a wireless connection with the remote speaker. The embodiment further includes presenting visual content via a display of the portable computing device, the visual content comprising an object positionally associated with a location in a real-world environment around the portable computing device, generating an audio signal corresponding to the object, and sending the audio signal to the remote speaker.

Abstract: Examples are disclosed that relate to heat-based cutting of an adhesive joint of a device. One disclosed example provides a device, comprising an adhesive joint connecting a first component and a second component via an adhesive layer, and a cutting affordance incorporated within the device and positioned within the adhesive joint or adjacent the adhesive joint.

Abstract: Embodiments are disclosed for a printed circuit board. An example printed circuit board includes a ground plane comprising a pattern of an electrically conductive material. The example printed circuit board further includes a circuit trace disposed adjacent to the ground plane, where one or more characteristics of one of more of the pattern of the electrically conductive material in the ground plane and the circuit trace vary based upon a directional change of the circuit trace.
