7615761, Nov 10, 2009

Filed:

Aug 28, 2008

Appl. No.:

12/199984

Inventors:

Lukas Hunziker - San Jose CA, US
Georg Herink - Brakel, DE
Arnaud Lepert - Belmont CA, US

Assignee:

Coherent, Inc. - Santa Clara CA

International Classification:

G01N 21/64

US Classification:

2504591

Abstract:

A method for detecting trace evidence materials on a surface comprises irradiating the surface with radiation from two or more lasers emitting radiation at different wavelengths selected to stimulate luminescence in the trace materials. The evidence is detected by observing the surface through an optical filter arranged to transmit the luminescence, while blocking transmission of the laser radiation wavelengths reflected or scattered from the surface.

International Classification:

A61N 7/02

US Classification:

601 2, 601 3

Abstract:

An ultrasonic transducer system for treating a portion of tissue. The ultrasonic transducer system includes a frequency generator, an ultrasonic transducer, and a transmitter element. The transducer receives an AC voltage from the frequency generator and produces an ultrasonic energy pulse at an ultrasonic frequency for a pulse width. The transmitter element is coupled to the transducer and is for irradiating a portion of skin tissue. The transmitter element has a chilled surface in contact with the skin tissue and an acoustic aperture for producing a substantially collimated energy beam. The beam has a width greater than 4 mm.

International Classification:

H01S 313

US Classification:

372 29014, 372 6, 372108, 385 31, 385 32, 385 33

Abstract:

An illumination system includes a multimode diode-laser and two optical fibers. Light from the diode-laser is directed into the first optical fiber having a first core diameter. The light exits the first optical fiber and is directed by an optical system into a second optical fiber having a core diameter greater than the first optical fiber and a numerical aperture greater than the numerical aperture of the optical system. A light beam exiting the second optical fiber has an intensity distribution having sharp edges and uniformity better than plus or minus ten percent over a central ninety percent of the beam.

International Classification:

A61N 5/06
A61N 5/067

Abstract:

Dermatological systems and methods for providing a therapeutic laser treatment of tissue having poor chromophore selectivity using a laser source having a grating element to provide laser light having reduced linewidth. In some embodiments, the linewidth is reduced by at least half compared to the linewidth that would be provided in a system without the grating filter element. The linewidth may be reduced in some cases to 500 GHz or less, 300 GHz or less, or 200 Hz or less.

International Classification:

A61B 18/14

Abstract:

Systems and methods for applying energy to treat body areas having fat deposits, cellulite, or loose skin are disclosed. The treatment energy is applied to a patient with multiple applicators in contact with the patient's skin, which heats the skin and underlying tissue, such as fat. As the temperature of the fat is raised and maintained for a period of time, the heat damages the fat cells. When multiple applicators apply energy to multiple treatment subareas within a general area of a patient's body at interleaving intervals, treatment efficiency is improved. In particular, compared to applying energy continuously to treat each subarea one at a time, applying energy in interleaving intervals sequentially to the various subareas reduces the total treatment time by having multiple subareas treated simultaneously while maintaining the temperature of the target tissue (e.g. fat) within the therapeutic temperature range.
