20090149843 | Tattoo Removal and Other Dermatological Treatments using Multi-Photon Processing - A system and method for providing multi-photon processing treatment to a patient. A localized, multi-photon processing event is initiated within a vicinity of an unwanted pigment in order to remove the pigment. The multi-photon processing event requires a relatively low energy, but very intense, pulse of light. The low amount of energy per pulse allows ablation of the material to be highly localized, with negligible thermal damage to surrounding material. The multi-photon event may be initiated by focusing a suitable electromagnetic pulse, such as a 2 mJ laser pulse having a 100 to 300 femtoseconds pulse duration, into a focal volume small enough that the intensity exceeds 10 | 06-11-2009 |
20090194513 | Method and apparatus for operating traveling spark igniter at high pressure - An ignition circuit and a method of operating an igniter (preferably a traveling spark igniter) in an internal combustion engine, including a high pressure engine. A high voltage is applied to electrodes of the igniter, sufficient to cause breakdown to occur between the electrodes, resulting in a high current electrical discharge in the igniter, over a surface of an isolator between the electrodes, and formation of a plasma kernel in a fuel-air mixture adjacent said surface. Following breakdown, a sequence of one or more lower voltage and lower current pulses is applied to said electrodes, with a low “simmer” current being sustained through the plasma between pulses, preventing total plasma recombination and allowing the plasma kernel to move toward a free end of the electrodes with each pulse. | 08-06-2009 |
