Abstract: An unmanned aerial vehicle with deployable components (UAVDC) may comprise a foldable propeller blade with a locking mechanism. Foldable propeller blades may have a stowed configuration and a deployed configuration relative to the UAVDC, and the foldable propeller blades may pivot about a hinge to move between configurations.

Abstract: A method to provide feedback, coaching, and ECG analysis during a cardiac event. A rescuer would typically be attempting cardiopulmonary resuscitation (CPR) and/or administering an electrical shock from a defibrillator and/or collecting electrocardiogram (ECG) data. The method includes a step of providing a data-generation device (e.g., a camera) and computing components. The computer is used to calculate distances on the fly using data generated by the data-generation device, such as a camera, that may be in motion. The method uses the computer to calculate movement of the chest of a patient and to assess outcomes. When CPR contaminates an ECG, the computer removes the unwanted contamination so that proper guidance to the rescuer can be delivered during CPR.

During operation of the semiconductor module arrangement, each controllable semiconductor element of the first plurality of controllable semiconductor elements generates switching losses and conduction losses, the switching losses being greater than the conduction losses. Further during operation of the semiconductor module arrangement, each controllable semiconductor element of the second plurality of controllable semiconductor elements generates switching losses and conduction losses, the conduction losses being greater than the switching losses.

Abstract: Systems and methods for determining that artificial commands, in excess of a threshold value, are detected by multiple voice activated electronic devices is described herein. In some embodiments, numerous voice activated electronic devices may send audio data representing a phrase to a backend system at a substantially same time. Text data representing the phrase, and counts for instances of that text data, may be generated. If the number of counts exceeds a predefined threshold, the backend system may cause any remaining response generation functionality that particular command that is in excess of the predefined threshold to be stopped, and those devices returned to a sleep state. In some embodiments, a sound profile unique to the phrase that caused the excess of the predefined threshold may be generated such that future instances of the same phrase may be recognized prior to text data being generated, conserving the backend system's resources.

Each of the first lower strap and the second lower strap have a thigh region, a waist region, and a connection region arranged between the thigh region and the waist region. A first connector is coupled to the connection region of the first lower strap. A second connector is coupled to the connection region of the second lower strap, and is configured to releasably attach to the first connector to at least partially limit movement of the first lower strap relative to the second lower strap. The connection region defines a connection width, and the thigh region defines a thigh width larger than the connection width.

Abstract: Warp sharding techniques to switch execution between divergent shards on instructions that trigger a long stall, thereby interleaving execution between diverged threads within a warp instead of across warps. The technique may be applied to mitigate pipeline stalls in applications with low warp occupancy and high divergence. Warp data cache locality may also be improved by concentrating memory accesses within a warp rather than spreading them across warps.
