Publication number: 20230114936Abstract: 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.Type: ApplicationFiled: July 15, 2022Publication date: April 13, 2023Applicant: Knite, Inc.Inventors: Artur P.

Patent number: 10431952Abstract: Method for producing ultraintense laser pulses in which Stimulated Raman Back-Scattering (SRBS) amplifies and compresses a seed pulse, as well as an inventive compact plasma device which may implement the method. SRBS may be achieved by counter-propagating the seed pulse and a pump pulse through a few millimeter-long plasma having a plasma frequency equal to the difference between the pump and the seed pulse frequencies. Dichroic mirrors may be arranged to provide two amplifying and compression passes through the plasma, allowing greater seed pulse amplification by mitigating Landau damping within the plasma that would occur in a single pass of a plasma of double the length. Alternate examples provide for 2n number of amplification and compression passes by providing n short plasma columns, where n?2, and additional, appropriately arranged dichroic mirrors. The compact size of the device, and the ultraintense, ultrashort pulses it emits, suit the device to dermatological applications.Type: GrantFiled: February 12, 2018Date of Patent: October 1, 2019Assignee: LIGHTSENSE IP LTD.Inventor: Szymon Suckewer

Patent number: 10092447Abstract: Ultra-short pulsed laser radiation is applied to a patient's eye to create a row of bubbles oriented perpendicular to the axis of vision. The row of bubbles leads to a region of the eye to be ablated. In a second step, a femtosecond laser beam guided through the row of bubbles converts it to a channel perpendicular to the axis of vision. In a third step, a femtosecond laser beam is guided through the channel to ablate a portion of the eye. Using a femtosecond laser with intensity in the range of 1011-1015 W/cm2 for the second and third steps facilitates multi-photon ablation that is practically devoid of eye tissue heating. Creating bubbles in the first step increases the speed of channel creation and channel diameter uniformity, thereby increasing the precision of the subsequent multi-photon ablation.Type: GrantFiled: April 26, 2016Date of Patent: October 9, 2018Inventors: Nicholas S.

Patent number: 9376178Abstract: A device for traversing water is disclosed that has a left and a right-foot hull and a pair of propulsion poles with attached propulsion pontoons. The propulsion poles are shaped and sized so that a person standing upright can use them to propel themselves across water. The underside of each hull has kick-forward plates that allow the hull to move unimpeded in one direction but not the other. A rail is connected near the inner edge of one hull, and a the rail follower fixed to the other hull, and slidably connected to the rail allow the hulls to more relative to each other in a direction parallel to their long axis.Type: GrantFiled: June 28, 2014Date of Patent: June 28, 2016Inventor: Szymon Suckewer

Patent number: 9351826Abstract: A system and method of replacing a lens to treat a cataract is disclosed. Cataractous tissue is ablated via a multi-photon process using focused, ultra-short laser pulses. Multi-photon ablation requires an energy intensity between 1013 to 1015 W/cm2. Using lasers having femto-second duration pulses, this intensity is achieved with 50 micro-Joules of energy, allowing material disruption with very little heating or shock. The multi-photon ablated material is removed through a micro-channel that leads from the multi-photon ablated region to at least the surface of the eye. Once the material is removed a pre-polymer fluid is injected in to fill the void. This polymerizes into a gel once inside the lens. The polymerized, transformed material matches both the transparency to visible light and the Young's modulus of healthy lens.Type: GrantFiled: May 4, 2014Date of Patent: May 31, 2016Inventors: Szymon Suckewer, Peter Hersh, Alexander Smits, Richard Register

Patent number: 9351794Abstract: A system and method of altering damaged mammalian skin using a multiphoton processes is disclosed. A femtosecond laser initiates a multiphoton event using pulse energies of 2-5 mJ thereby causing multiphoton ablation without damaging surrounding tissue. The laser is focused to the vicinity of a target organelle that occurs naturally within the damaged skin, and is related to the dermatological condition being addressed. The type of organelle depends on the condition being addressed, and may be targeted by the depth beneath the surface of the skin at which it is located. The femtosecond laser beam is focused to an intensity of least 1012 W/cm2 to initiate the multiphoton event transforms the targeted organelle to mitigate the damage to the skin.Type: GrantFiled: June 2, 2015Date of Patent: May 31, 2016Inventors: Szymon Szymon Suckewer, Alexander Smits, Steven Hubert

Publication number: 20160120700Abstract: Ultra-short, ultra-intense laser pulses from a first laser beam are applied to a patient's cornea, creating a temporary micro-channel extending from the cornea surface to an end-point within it. Further ultra-short ultra-intense laser pulses from a second laser beam, are then delivered to the endpoint along with further pulses from the first beam, but delayed by a few nanoseconds. The micro-channel acts as a light-guide for these pulses. At the end point, they are focused to sufficient intensity to multiphoton ablate surrounding stromal tissue. With a few small entrance holes and without the lamellar flap necessary in LASIK procedures, the cornea is reshaped by rotating the direction of the laser beam. The vertical location of ablation is adjusted precisely using an applanator on the corneal surface. The multiphoton ablated tissue is ejected via the micro-channels, allowing the cornea surface to collapse after the procedure, changing its refractive power.Type: ApplicationFiled: October 3, 2015Publication date: May 5, 2016Inventors: Taehee Han, Szymon Suckewer, Peter Hersh

Patent number: 9247995Abstract: A method for removing tattoos using two laser beams and a multi-photon process is disclosed. A 0.1 to 100 nsec pulse secondary laser beam focused to 108 W/cm2 creates a temporary channel from the skin surface to the tattoo pigment. A 100 fsec pulse main laser beam is then guided through the channel to the pigment and focused to sufficient intensity, i.e., 1012 W/cm2 or more, to initiate a multi-photon process that breaks up the pigment, disrupting its light reflecting properties. The channel allows the main laser beam unobstructed passage to the pigments, resulting in efficient use of the main laser. The pigment fragments escape through the temporary channel or diffuse into the blood stream. A suitably configured Ti/Sapphire laser beam is split into two components, with an uncompressed component used as the secondary laser beam, and a compressed component as the main laser beam.Type: GrantFiled: November 4, 2014Date of Patent: February 2, 2016Assignee: Trustees of Princeton UniversityInventor: Szymon Suckewer
