Publication number: 20110285389Abstract: A magnetic screening system uses directional gradiometers with high resolution and accuracy to measure magnetic field signatures of target objects (e.g., gun, knife, cell phone, keys) in a volume of interest. The measured signatures can be compared to signatures of known objects stored in a local database. Various mathematical processes may be used to identify or classify target object signatures. In a network of magnetic screening systems, the magnetic screening systems can transmit signatures to a central signature database, and a management computer can share the central signature database with all of the magnetic screening systems on the network. The magnetic screening system can operate in multiple modes, such as a tracking mode, measurement mode, and self-test mode. Through use of unique processes and designs, the magnetic screening system can achieve a high rate of processing persons for target objects.Type: ApplicationFiled: January 24, 2011Publication date: November 24, 2011Applicant: Assurance Technology CorporationInventors: Thomas W.

Patent number: 7573257Abstract: A magnetic screening system uses directional gradiometers with high resolution and accuracy to measure magnetic field signatures of target objects (e.g., gun, knife, cell phone, keys) in a volume of interest. The measured signatures can be compared to signatures of known objects stored in a local database. Various mathematical processes may be used to identify or classify target object signatures. The magnetic screening system can operate in multiple modes, such as a tracking mode, measurement mode, calibration mode, and self-test mode. Calibration may be performed in substantially continous manner to allow calibration parameters to be adjusted during system operation (e.g., tracking mode) to compensate for changes in conditions that may impact calibration parameters. Through use of unique processes and designs, the magnetic screening system can achieve a high rate of processing persons for target objects.Type: GrantFiled: October 31, 2007Date of Patent: August 11, 2009Assignee: Assurance Technology CorporationInventors: Kai Wing Li, Louis Stephen Palecki, Antonio G.

Patent number: 6632218Abstract: A long pulse alexandrite laser hair removal system is disclosed using light pulses of greater than 1 msec and fluences between 10 and 50 J/cm2. The use of an alexandrite laser allows good penetration while still achieving an acceptable combination of hemoglobin and melanin absorption. The use an index-matching application on the skin sections to be treated is also described. This substance will be absorbed into the epidermal layer to provide better coupling of the laser light into the skin. Also, and most advantageously, it will reduce reflections at the epidermal-dermal junction, which can lead to the damage of the skin. Also a topical thermal or photochromic indicator is suggested since skin irradiation in the near-infrared generally does not produce any characteristic skin color change as is found when using pulsed dye lasers, for example.Type: GrantFiled: October 21, 1999Date of Patent: October 14, 2003Assignee: Cynosure, Inc.Inventors: Horace W.

Publication number: 20010009998Abstract: A method for treating simple wrinkles caused by age or sun exposure comprises treating blood vessels in the wrinkles with laser light. The laser light may have a wavelength between 577 and 585 nm. The laser light may also be a laser light pulse having a pulse duration that is greater than 0.2 msec, or alternatively, greater than 0.5 msec. The output pulse may be generated with a dye laser, for instance, by exciting dye solution in a resonant cavity with one or more flashlamps. A further treatment method comprises irradiating wrinkle-bearing skin with a laser pulse where the pulse duration is selectively matched to the thermal relaxation time of blood vessels in the targeted skin.Type: ApplicationFiled: March 1, 2001Publication date: July 26, 2001Applicant: Cynosure, Inc.Inventors: Horace W.

Patent number: 5624435Abstract: A flashlamp-excited dye laser generating light pulses for therapy has a circulator which circulates a gain media through a dye cell. A controller coordinates operation by triggering flashlamps to excite the laser gain media while the circulator is circulating the gain media. This operation enables the generation of laser light pulses with a duration of at least one millisecond. If the flow velocity of dye solution is great enough such that the new solution enters the resonant cavity before the solutions in the cavity are substantially spent, ultra-long pulses with high fluences are possible. Specifically, longer pulses of up to 50 msec can be achieved with energies of up to 50 Joules. These energies enable reasonable spot sizes, which makes the invention relevant to dermal therapy, for example.Type: GrantFiled: June 5, 1995Date of Patent: April 29, 1997Assignee: Cynosure, Inc.Inventors: Horace W.
