Abstract: A training bat for training athletes in sports such as baseball and softball is provided. The bat provides a significantly reduced moment of inertia for a given weight of bat. The combination of high weight and low moment of inertia requires significantly exertion to move the bat forwards through a swing without requiring excessive exertion to rotate the bat through the swing. The training bat allows for swing strength and speed while simultaneously developing good hand motion to rotate the bat.

Abstract: Systems and techniques are disclosed for mobile device network traffic modification and user identity based restrictions on data access. One of the methods includes a user device receiving a request to enter a restricted mode, the restricted mode enforcing compliance of rules associated with electronic personal health information (ePHI). A user interface presented on the user device is updated according to restricted mode. Functionality of the user device is constrained based on the restricted mode, with information generated during the restricted mode being encrypted on the user device.
