    • A method of controlling an aircraft, missile, munition or ground vehicle with plasma actuators, and more particularly of controlling fluid flow across their surfaces or other surfaces which would benefit from such a method, includes the design of an aerodynamic plasma actuator for the purpose of controlling airflow separation over a control surface of a aircraft, missile, or a ground vehicle, and a method of determining a modulation frequency for the plasma actuator for the purpose of fluid flow control over these vehicles. Various embodiments provide steps to increase the efficiency of aircraft, missiles, munitions and ground vehicles. The method of flow control reduces the power requirements of the aircraft, missile, munition or ground vehicle. These methods also provide alternative aerodynamic control using low-power hingeless plasma actuator devices.

    • A system and method for expiring a software module on a wireless communication device is disclosed. According to one embodiment, the method comprises receiving, at the wireless communication device, an expiration notice for the software module and determining if license renewal of the software module is automatic. If the license renewal is not automatic, then the method includes notifying a user of the wireless communication device of the receipt of the expiration notice, and de-activating the software module upon receipt of instructions to not renew. In certain embodiments, the software module is de-activated after an expiration of a trial period if no instructions are received from the user in response to the notifying step. The method may further include sending the renewal instructions to the software module server upon receipt of instructions to renew, receiving an activation key from the software module server in response to sending the renewal instructions, and activating the software module utilizing the activation key. If the license renewal is automatic or receipt of instructions to renew are received, then the method includes sending the renewal instructions to the software module server, receiving an activation key from the software module server, and activating the software module utilizing the activation key.
