  • Publication number: 20200143584
    Abstract: In one embodiment, a method includes receiving image data corresponding to an external environment of a user. The image data is captured at a first time and comprises a body part of the user. The method also includes receiving a first tracking data generated based on measurements made at the first time by at least one motion sensor associated with the body part; generating, based at least on the image data, a model representation associated with the body part; receiving a second tracking data generated based on measurements made at a second time by the at least one motion sensor associated with the body part; determining a deformation of the model representation associated with the body part based on the first tracking data and the second tracking data; and displaying the deformation of the model representation associated with the body part of the user.

  • Publication number: 20200090406
    Abstract: A mixed reality (MR) simulation system includes a console and a head mounted device (HMD). The MR system captures stereoscopic images from a real-world environment using outward-facing stereoscopic cameras mounted to the HMD. The MR system preprocesses the stereoscopic images to maximize contrast and then extracts a set of features from those images, including edges or corners, among others. For each feature, the MR system generates one or more two-dimensional (2D) polylines. Then, the MR system triangulates between 2D polylines found in right side images and corresponding 2D polylines found in left side images to generate a set of 3D polylines. The MR system interpolates between 3D vertices included in the 3D polylines or extrapolates additional 3D vertices, thereby generating a geometric reconstruction of the real-world environment. The MR system may map textures derived from the real-world environment onto the geometric representation faster than the geometric reconstruction is updated.

  • Patent number: 9703516
    Abstract: A flexible input/output controller logic interfaces with existing input/output controllers (IOC's) in order to configure the amount of data sent to and received from the IOC's. The flexible I/O interface receives data from a component at a rate determined by the particular component. The flexible I/O interface then feeds the received data to a traditional I/O controller at a rate suitable for the I/O controller. Thus, the interface to the individual I/O controllers is maintained. The flexible I/O logic balances bandwidth between a plurality of individual I/O controllers in order to better utilize the overall system I/O bandwidth. In one embodiment, the I/O configuration managed by the flexible I/O logic is determined during system-build, while in another embodiment, the I/O configuration is set during system initialization.

  • Patent number: 9655067
    Abstract: A method, a non-transitory computer-readable medium and an apparatus for receiving a data packet that is transmitted from a first sensor node are disclosed. For example, the method performs a channel scan of a particular burst of channel scans. When the preamble packet is detected, the method determines whether the preamble packet is addressed to the second sensor node. When the preamble packet is addressed to the second sensor node, the method sends an acknowledgement packet to the first sensor node. The method then receives the data packet that is transmitted from the first sensor node. The method then sleeps for a duration of time, when there is no packet transmission that is ongoing that is destined to the second sensor node.
