  • Publication number: 20220253131
    Abstract: In one embodiment, a method includes capturing, using one or more cameras implemented in a wearable device worn by a user, a first image depicting at least a part of a hand of the user holding a controller in an environment, identifying one or more features from the first image to estimate a pose of the hand of the user, estimating a first pose of the controller based on the pose of the hand of the user and an estimated grip that defines a relative pose between the hand of the user and the controller, receiving IMU data of the controller, and estimating a second pose of the controller by updating the first pose of the controller using the IMU data of the controller. The method utilizes multiple data sources to track the controller under various conditions of the environment to provide an accurate controller tracking consistently.

  • Publication number: 20220175799
    Abstract: Elevated cholesterol levels, especially low lipoprotein cholesterol (LDL-C), leads to atherosclerosis—which may increase the risk of heart attack, stroke, and peripheral artery disease. Statins are common medications that can help lower cholesterol levels. However, myopathy can be a serious side effect that prevents patients from taking statins and significantly decreases overall quality of life. Described herein are dosage forms containing select combinations of natural herbal extracts and phytonutrients having the surprising ability to lower LDL-C levels in amounts comparable to statin drugs without noted side effects such as myopathy.

  • Patent number: 10661187
    Abstract: A track set for a toy vehicle includes a track portion and an actuatable mechanism. The track portion defines a track path between a first end of the track portion and a second end of the track portion. The actuatable mechanism attempts to capture a toy vehicle as the toy vehicle moves along the track path, between the first end and the second end, in response to select triggerings generated by the toy vehicle traversing the track path. The actuatable mechanism removes the toy vehicle from the track portion when the actuatable mechanism captures the toy vehicle. The actuatable mechanism may include a carriage that captures the toy vehicle. The carriage is initially disposed in a rest position that is off-path from the track path and is selectively movable, along a carriage pathway, to an actuated position that is also off-path from the track path.

  • Patent number: 10307106
    Abstract: Systems and methods for estimating time-dependent voltages that are induced in electrophysiological monitoring systems by magnetic field gradients generated during a magnetic resonance imaging (“MRI”) scan are provided. The gradient-induced voltages are subsequently removed from signals acquired with the electrophysiological monitoring system during an MRI scan. As an example, the electrophysiological monitoring system can include an electrocardiography (“ECG”) system, an electroencephalography (“EEG”) system, an electromyography (“EMG”) system, a voltage device tracking (“VDT”) system, and so on. The gradient-induced voltages are estimated using a two-step procedure in which a learning algorithm is used to determine fitting parameters to be used in a model of the gradient-induced voltages. The fitting parameters are then used together with the model to extract the gradient-induced voltages from signals acquired during an MRI scan. The gradient-induced voltages can then be removed from the acquired signals.

  • Patent number: 10277813
    Abstract: A viewing device, such as a virtual reality headset, allows a user to view a panoramic scene captured by one or more video capture devices that may include multiple cameras that simultaneously capture 360° video data. The viewing device may display the panoramic scene in real time and change the display in response to moving the viewing device and/or changing perspectives by switching to video data being captured by a different video capture device within the environment. Moreover, multiple video capture devices located within an environment can be used to create a three-dimensional representation of the environment that allows a user to explore the three-dimensional space while viewing the environment in real time.

  • Patent number: 10084959
    Abstract: A video capture device may include multiple cameras that simultaneously capture video data. The video capture device and/or one or more remote computing resources may stitch the video data captured by the multiple cameras to generate stitched video data that corresponds to 360° video. The remote computing resources may apply one or more algorithms to the stitched video data to adjust the color characteristics of the stitched video data, such as lighting, exposure, white balance contrast, and saturation. The remote computing resources may further smooth the transition between the video data captured by the multiple cameras to reduce artifacts such as abrupt changes in color as a result of the individual cameras of the video capture device having different video capture settings. The video capture device and/or the remote computing resources may generate a panoramic video that may include up to a 360° field of view.
