    Abstract: Embodiments are disclosed for full body pose estimation using features extracted from multiple wearable devices. In an embodiment, a method comprises: obtaining point of view (POV) video data and inertial sensor data from multiple wearable devices worn at the same time by a user; obtaining depth data capturing the user's full body; extracting two-dimensional (2D) keypoints from the POV video data; reconstructing a full body 2D skeletal model from the 2D keypoints; generating a three-dimensional (3D) mesh model of the user's full body based on the depth data; merging nodes of the 3D mesh model with the inertial sensor data; aligning respective orientations of the 2D skeletal model and the 3D mesh model in a common reference frame; and predicting, using a machine learning model, classification types based on the aligned 2D skeletal model and 3D mesh model.

    Abstract: Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.

    Abstract: A transmitter device for an inductive energy transfer system can include a DC-to-AC converter operably connected to a transmitter coil, a first capacitor connected between the transmitter coil and one output terminal of the DC-to-AC converter, and a second capacitor connected between the transmitter coil and another output terminal of the DC-to-AC converter. One or more capacitive shields can be positioned between the transmitter coil and an interface surface of the transmitter device. A receiver device can include a touch sensing device, an AC-to-DC converter operably connected to a receiver coil, a first capacitor connected between the receiver coil and one output terminal of the AC-to-DC converter, and a second capacitor connected between the receiver coil and another output terminal of the AC-to-DC converter. One or more capacitive shields can be positioned between the receiver coil and an interface surface of the receiver device.
