| Number | Title | Issue Date |
| 7202712 | Multiphase resonant pulse generators A multiphase resonant pulse generator (74) has N groups of N−1 switches (44,46,48) which, when activated, form N paths from a power supply (Vdc) to ground or a reference voltage. Here N is a positive integer greater than 2. Each of the paths includes... | 04/10/2007 |
| 6762561 | Radio frequency resonator An apparatus having a radio frequency resonator, which has a coil, a capacitor means and at least one switch means being associated with another capacitor means, a resistor means and a high voltage supply means, one end of the switch means being connected to a junct... | 07/13/2004 |
| 6285063 | Resonant circuit having a resonant body mechanically oscillated by electrostatic or magnetic forces The resonant circuit has at least one resonant body of a semiconductor material anchored on the surface of a semiconductor substrate, at least one first electrode being arranged at said semiconductor material, and at least one second electrode. The first ... | 09/04/2001 |
| 4070636 | Plural loop spark gap RF pulse radiation converter The high-power, short-pulse array is a self-contained radiating oscillator system which radiates a high peak-power pulse of radio frequency energy. The radiated pulses contain only a few cycles of RF and hence it is a short-pulse emitter. The device conta... | 01/24/1978 |
