A method and system for assessing heaviness of a swing in sport of tennis is disclosed. The system may display the calculated heaviness of a groundstroke in real-time. As the player hits ground strokes, the system will measure linear and rotational speed of the ball and calculate a heaviness value based on the physics of translational and rotational kinetic energy of the ball.

Securing inter-process communications includes receiving, from a device that supports a first process that is an instantiation of a first application being executed, a request to initiate inter-process communications. Securing inter-process communications also includes replying to the device with a request for information of a first digital certificate that uniquely authenticates an identity of the first process. An identity of a second process that is a distinct instantiation of the first application is authenticated using a second digital certificate distinct from the first digital certificate.

Secure inter-process communications

Inter-process communications between a first process and a second process are secured. A first process recognizes that inter-process communications must be initiated with a second process. A first computer that supports the first process submits a request to initiate inter-process communications with a second computer that supports the second process. The second computer replies to a request to initiate inter-process communications by replying to the first computer with a request for information of a digital certificate that authenticates the first process.
