Abstract: A scenario is simulated by providing an agent that is an object in the scenario, providing a time window for the scenario that spans the farthest reachable past time and the farthest reachable future time with respect to a present time for the agent and/or at least one player that interacts with the simulated scenario, providing at least one event that represents a change in at least one attribute of the agent, and updating a state of the scenario by applying the at least one event to the agent within the time window.

Abstract: The reconfigurable ultrasound array disclosed herein is one that allows groups of subelements to be connected together dynamically so that the shape of the resulting element can be made to match the shape of the wave front. This can lead to improved performance and/or reduced channel count. Reconfigurability can be achieved using a switching network. A methodology and an algorithm are disclosed that allows the performance of this switching network to be improved by properly choosing the configuration of the switching network.

Abstract: A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic). The reconfigurability allows the size and spacing of the sensor elements to be a function of the distance from the beam center. This feature improves performance for imaging systems having a limited channel count. The improved performance, for applications in which multiple transmit focal zones are employed, arises from the ability to adjust the aperture for a particular depth.
