Abstract: A system including sensors and a processor is described. The sensors are configured to sense force. The processor receives force measurements from the sensors. The force measurements correspond to touch locations. The processor is also configured to detect a gesture based on the force measurements and the touch locations and to provide at least one signal indicating an identification of the gesture.

Abstract: A method and apparatus for transaction level modeling where communications occur between modules in the system that contain time annotations is described. An apparatus includes an initiator module, a target module, and a communications channel with each being modeled as an executable behavioral model. The communications channel transports burst information between the initiator module and the target module. The communications channel has a timing variable function to store timing variables and derive timing information associated with each individual transfer within a burst transaction during a simulation.
