  • Patent number: 9497760
    Abstract: Methods by a radio unit and related radio units are disclosed which control capacity of baseband processing resources allocated to a radio communication cell. The method includes determining a deadline margin for a prior transmission time interval (TTI) based on a difference between a time when baseband processing of data for transmission completed and a defined deadline time for completion of the baseband processing. The method further includes determining a desired capacity of baseband processing resources to allocate to the radio communication cell for a present TTI, and controlling capacity of baseband processing resources allocated to the radio communication cell for the present TTI based on the deadline margin and the desired capacity.

  • Publication number: 20160314620
    Abstract: Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual teammates in a simulated environment of a virtual reality sporting event. As the sporting event unfolds, the user's actions and decisions are monitored by the simulated environment. The sports training environment evaluates the user's performance, and provides quantitative scoring based on the user's decisions and timing. Coaches and other users may design customized scenarios or plays to train and test users, and the resultant scores may be reviewed by the coach. Athletes in a virtual environment may experience an increased number of meaningful play repetitions without the risk of injury. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills.

  • Publication number: 20160314624
    Abstract: A display device system providing augmented reality and virtual reality displays in the same device and a method for switching between augmented reality and virtual reality modes in the embodiments of the device are disclosed. The system enables users to view an augmented reality setting, interact with objects, and switch to a virtual reality setting or vice versa without having to switch devices. Some embodiments may include a shuttering mechanism that blocks light from an ambient environment when switching from the augmented reality mode to the virtual reality mode so that ambient light or objects do not interrupt the virtual reality landscape. When switching from virtual reality to augmented reality, the shuttering mechanism may open allowing the user to see the real environment within an augmented setting.
