    Abstract: Various implementations disclosed herein include devices, systems, and methods that create a 3D video that includes determining first adjustments (e.g., first transforms) to video frames (e.g., one or more RGB images and depth images per frame) to align content in a coordinate system to remove the effects of capturing camera motion. Various implementations disclosed herein include devices, systems, and methods that playback a 3D video and includes determining second adjustments (e.g., second transforms) to remove the effects of movement of a viewing electronic device relative to a viewing environment during playback of the 3D video. Some implementations distinguish static content and moving content of the video frames to playback only moving objects or facilitate concurrent playback of multiple spatially related 3D videos. The 3D video may include images, audio, or 3D video of a video-capture-device user.

    Abstract: Embodiments are directed to a blood pressure measurement device that includes a strap configured to couple the blood pressure measurement device to a user, an air pump coupled to the strap and having a housing defining a surface facing the user, and an inflatable chamber positioned on the surface of the air pump and fluidly coupled to the air pump. The inflatable chamber can be positioned between the air pump and the user when the blood pressure measurement device is worn by the user and expand towards the user when inflated. The blood pressure measurement device can also include a pressure sensing chamber coupled to the inflatable chamber and positioned between the inflatable chamber and the user when the blood pressure measurement device is worn by the user. The pressure sensing chamber can include a liquid volume and a pressure sensing device configured to detect a pressure of the liquid volume.

    Abstract: An apparatus configured to establish a first radio link for short range communications using a first protocol and a second radio link for short range communications using a second protocol, wherein the first and second radio links share an antenna, process traffic load information for the first radio link, the information being dependent on configuration parameters for the first radio link, determine, based on the information, time domain resources available for second data traffic on the second radio link, based on the time domain resources available for the second data traffic on the second radio link, determine a fragmentation size for packets sent on the second radio link and generate transmissions to exchange the second data traffic in the time domain resources available for the second data traffic on the second radio link in fragmented packets according to the determined fragmentation size.

    Abstract: Stabilizing camera preview frames involves obtaining preview frames and associated camera motion signals, smoothing out the trajectory of these frames to correct for camera movement, and then displaying the corrected frames. The process includes comparing current and prior preview frames and their motion signals to calculate smoothed trajectories and apply appropriate rotation and translation corrections. The specifics of trajectory smoothing take into account factors such as motion state, lighting, or capture mode, which can influence the strength of the smoothing parameter. Transform matrices are utilized based on correction rotation to adjust sample points within images, and special considerations like camera sag are factored into the image corrections.
