Abstract: A circuit that can rapidly and precisely change the state of any circuit with some form of memory, whether it is a voltage across a capacitor, a current in an inductor, a digital value, or otherwise, using cyclically swapped circuits. For the case of a value stored on a capacitor: By swapping extra capacitors with preemptively set voltages using electronic switches, inherent settling times and defects of real RC circuits can be replaced with electronic switching times and switch defects. This dramatically improves speed and performance and is applicable on many circuit types including faster acquisition sample and hold circuits, faster amplifier nulling circuits, and any circuit that requires rapidly changing the DC voltage stored on a capacitor, and any circuit that requires rapidly changing the state or a circuit that has memory.

Abstract: A method and apparatus which enables a facility or entity such as ships, airplanes, and land based sites, that transmits and receives radar signals to receive any incoming radar signal, while blocking reception of any signals generated by the facility or entity itself. The method comprises transmitting a primary signal from an rf generator; providing a second signal which is synchronized with the primary signal matching in both phase and amplitude, but with a phase difference of 180 degrees so that the two signals sum to zero. The second signal travels through a voltage controlled attenuator and thru a voltage controlled phase shifter. Combining in a combiner the second signal with a signal radiated by a transmitting antenna and received by a receiving antenna that connects into a transmission enabling mechanism, and then transmitting the combined signal to a detector apparatus.

Abstract: A method and apparatus which enables a facility or entity such as ships, airplanes, satellites, and land based sites, that transmits and receives radar signals to receive any incoming radar signal, or any electromagnetic signals in the frequency range of 1 Ghz-30 Ghz, while blocking reception of any signals generated by the facility or entity itself. The method comprises transmitting a primary signal from an rf generator; providing a second signal which is synchronized with the primary signal matching in both phase and amplitude, but with a phase difference of 180 degrees so that the two signals sum to zero.
