    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.

    Abstract: An electronic device may be provided with a housing having sidewalls, a dielectric cover, and a conductive plate. A display may be mounted to the sidewalls opposite the dielectric cover. A logic board may be interposed between the display and the plate. The device may include a phased antenna array on a first module and an ultra-wideband (UWB) on a second module. The first and second modules may be surface-mounted to the main body of a flexible printed circuit between the plate and the dielectric cover. The UWB antenna and the array may convey radio-frequency signals through the dielectric cover. The flexible printed circuit may have a tail that carries the transmission lines for the UWB antenna and the array. The tail may be folded through a hole in the mid-chassis and coupled to a radio-frequency connector on the logic board.
