摘要： Disclosed subject matter relates to techniques for predicting jamming effectiveness. In one approach, platform models and propagation models are used to predict maximum threat communication range when jamming is used and when jamming is not used. The maximum range information may then be used to calculate jammer effectiveness. In another approach, probability-based techniques are used to predict jamming effectiveness for a system of interest.

摘要： A method, device and circuit which applies an electrostatic repulsion pushing force to a MEM switch armature during an opening process. The repulsive force adds to the spring restoration force on the armature, increasing the opening speed of the switch and aids in overcoming stiction effects. The inventive switch includes a contact electrically connected to a first terminal of the switch. A throw is electrically connected to a second terminal of the switch. Finally, a mechanism is provided for opening the switch by electrostatically causing the throw to disengage the contact. In the illustrative implementation, the mechanism for opening the switch includes a first charge storage structure mounted on the throw and a second charge storage structure mounted in proximity to the first charge storage structure. When charges are applied between the first and the second charge storage structures, a force of repulsion is created or a force of attraction is created depending on the polarity of the potential.

摘要： A single pole, double throw micro-electromechanical (MEM) switch. The inventive switch includes a first contact providing a first terminal of the switch. A second contact provides a second terminal of said switch. A cantilever beam provides a third terminal of the switch. The inventive switch includes a system for electrostatically pushing or pulling the beam to disengage the first contact and engage the second contact. In an illustrative implementation, the system for electrostatically operating the switch includes a first charge storage structure on the beam, a second charge storage structure on the switch, and an electrical supply for creating an electrical charge on the first and the second charge storage structures. The first and second charge storage structures are effective to create a force of repulsion therebetween on the application of an electrical charge thereto. The "pull" electrostatic force closes the MEM switch. The "push" force aids in opening the switch. The "push" capability is the result of the use of like (same polarity) electrostatic charges on the control surfaces. The like charges provide an electrostatic repulsion force during the switch opening process.
