20090273785 | ELECTRIC GATED INTEGRATOR DETECTION METHOD & DEVICE THEREOF - A cavity ring down system is optimized to precisely measure trace gases or particles in an air sample by using time sampling detection and multiple-sample averaging resulting in a high signal-to-noise ratio. In one embodiment, a cavity ring down system is programmed to measure the rise time and the fall time of the light level in an optical cavity. The cavity ring down system is programmed to integrate a plurality of sample portions during a rise time and a plurality of sample portions during a fall time (in alternate intervals) to obtain a time constant with no sample present and a time constant with sample present. The measurements are used to calculate trace gases in the air sample. | 11-05-2009 |

20090143718 | PLASMA TREATMENT PROBE - A plasma treatment probe may include a hollow, tubular electrode defining an interior region, and a coaxial insulating tube configured to enclose the electrode. The insulating tube may form a gas flow outlet at one end. An outer chamber may enclose the insulating tube and the hollow electrode, and may have a gas inlet for receiving a gas mixture. The hollow electrode may be configured to receive nanosecond electric pulses, while a gas mixture flows from the gas inlet through the interior region of the electrode, so that a non-thermal plasma can be ignited that exits from the gas flow outlet onto a region of a patient's body to medically treat the region. | 06-04-2009 |
20100038971 | NANOSECOND PULSE GENERATOR - This invention relates to a pulse generator circuit for delivering a short high current pulse to a load. This pulse generator comprises a junction recovery diode, a switch, a first resonant circuit and a second resonant circuit. The diode may be configured to store charges in its depletion layer when there is a forward flow of a current and to rapidly switch open after the depletion layer is discharged by a reverse flow of a current. After the diode rapidly switch opens, the pulse generator may provide a reverse current to the load. This pulse generator may be configured to generate at least one pulse that is having a length of no more than 100 nanoseconds at the full-width-at-half-maximum and an amplitude of at least 1 kilovolt.
