Abstract: A method for extracting a moving object in a video by an object detection system operated by at least one processor is provided. The method comprises receiving a certain unsmoothed frame included in the video, and if the certain frame is not a first frame of the video, calculating a pixel intensity difference between reference pixels of a reference background sample extracted from the first frame of the video and each of frame pixels of the certain frame. The method further comprises determining a segmentation of a background and a foreground in the certain frame based on the calculated pixel intensity difference and a predetermined threshold, and extracting the foreground from the certain frame as the object according to a similarity measurement value between the reference pixels and the frame pixels.

Abstract: A knotless tissue repair assembly for attachment of tissue to bone includes an anchoring implant with a length of suture threaded therethrough. The implant is preferably a soft flexible three-dimensional structure. The implant may be actuated from a first elongate low profile shape into a second short radially expanded shape having a larger diameter than the hole through which it was placed. The suture extends through the anchor, through a tissue to be secured, and back through a designated suture-binding region or passageway within the anchor enabling the suture to be secured therein and without the need for a physician to tie a knot. Further tension applied to a suture leg approximates the tissue to the anchor until a desired tension or distance between the tissue and anchor is achieved.

Abstract: Autonomous vehicles utilize perception and understanding of vehicles to predict behaviors of the vehicles, and to plan a trajectory. Understanding of attributes of vehicles may be improved through sensor fusion. Sensor fusion can be computationally expensive and may be difficult to implement in a real-time vehicle understanding system. To limit computational complexity while benefiting from machine learning across modalities, sensor fusion may be selectively implemented for a subset of task groups of a multi-task machine learning model. In some cases, part-based understanding may be implemented before fusion to limit the features being fused together to part features that are most salient for the task group. In addition, sensor data and features that may be fused together can be limited to sensor data and features within a desired field of view. A model that implements sensor fusion may be disabled for objects that are beyond a threshold distance.

Abstract: Autonomous vehicles utilize perception and understanding of road users to predict behaviors of the road users, and to plan a trajectory for the vehicle. Understanding subtypes and attributes of vehicles may help autonomous vehicles better predict behaviors of and react to vehicles in a variety of road situations. To offer additional understanding capabilities, an additional understanding model is added to the perception and understanding pipeline to improve classification of vehicles and extraction of attributes of the vehicles. The exemplary architectures of the understanding model balance recall and precision performance metrics and computational complexity.

Abstract: Various systems and methods that enhance an exercise activity performed by a user are described. In some embodiments, a rowing machine is described. The rowing machine includes devices and/or components that can enhance the user experience of a user performing a rowing activity using the rowing machine, such as during a rowing-based exercise class. For example, the rowing machine can include different sensors that capture information associated with a position or movement of a seat of the rowing machine relative to a position or movement of a handle of the rowing machine and utilize the captured information to perform actions associated with the user performing the rowing activity.

Abstract: Tissue repair systems which use knotless all-suture anchors and have the ability to lock multiple repair sutures within the anchor construct. The anchor construct includes a tension suture wrapped or looped upon itself to create an open eyelet, through which multiple repair sutures originating in soft tissue are passed. The location of the eyelet may be anywhere inside the all-suture anchor or adjacent to the exterior of the anchor body. Tensioning of the tension suture causes the eyelet to restrict movement of the repair sutures and secures them within or against the anchor body.
