Patent number: 6515737Abstract: A method and system of combining gated intensifiers and advances in solid-state, short-pulse laser technology, compact systems capable of producing high resolution (i.e., approximately less than 20 centimeters) optical images through a scattering medium such as dense clouds, fog, smoke, etc. may be achieved from air or ground based platforms. Laser target designation through a scattering medium is also enabled by utilizing a short pulse illumination laser and a relatively minor change to the detectors on laser guided munitions.Type: GrantFiled: January 3, 2001Date of Patent: February 4, 2003Assignee: The Regents of the University of CaliforniaInventor: Michael D. Perry

Patent number: 6490469Abstract: Method and system disclosed herein include noninvasively detecting, separating and destroying multiple masses (tumors, cysts, etc.) through a plurality of iterations from tissue (e.g., breast tissue). The method and system may open new frontiers with the implication of noninvasive treatment of masses in the biomedical area along with the expanding technology of acoustic surgery.Type: GrantFiled: March 14, 2001Date of Patent: December 3, 2002Assignee: The Regents of the University of CaliforniaInventor: James V. Candy

Patent number: 6417754Abstract: A three-dimensional coil inductor is disclosed. The inductor includes a substrate; a set of lower electrically conductive traces positioned on the substrate; a core placed over the lower traces; a set of side electrically conductive traces laid on the core and the lower traces; and a set of upper electrically conductive traces attached to the side traces so as to form the inductor. Fabrication of the inductor includes the steps of forming a set of lower traces on a substrate; positioning a core over the lower traces; forming a set of side traces on the core; connecting the side traces to the lower traces; forming a set of upper traces on the core; and connecting the upper traces to the side traces so as to form a coil structure.Type: GrantFiled: December 7, 1998Date of Patent: July 9, 2002Assignee: The Regents of the University of CaliforniaInventors: Anthony F. Bernhardt, Vincent Malba

Patent number: 6226346Abstract: Optical systems compatible with extreme ultraviolet radiation comprising four reflective elements for projecting a mask image onto a substrate are described. The four optical elements comprise, in order from object to image, convex, concave, convex and concave mirrors. The optical systems are particularly suited for step and scan lithography methods. The invention enables the use of larger slit dimensions associated with ring field scanning optics, improves wafer throughput, and allows higher semiconductor device density. The inventive optical systems are characterized by reduced dynamic distortion because the static distortion is balanced across the slit width.Type: GrantFiled: June 9, 1998Date of Patent: May 1, 2001Assignee: The Regents of the University of CaliforniaInventor: Russell M. Hudyma

Patent number: 6225635Abstract: A system and method is disclosed for optically locating a microchannel position. A laser source generates a primary laser beam which is directed at a microchannel plate. The microchannel plates include microchannels at various locations. A back-reflectance beam detector receives a back-reflected beam from the plate. The back-reflected beam is generated when the primary beam reflects off of the plate. A photodiode circuit generates a trigger signal when the back-reflected beam exceeds a predetermined threshold, indicating a presence of the microchannel. The method of the present invention includes the steps of generating a primary beam, directing the primary beam to a plate containing a microchannel, receiving from the plate a back-reflected beam generated in response to the primary beam, and generating a trigger signal when the back-reflected beam exceeds a predetermined threshold which corresponds to a presence of the microchannel.Type: GrantFiled: August 7, 1998Date of Patent: May 1, 2001Assignee: The Regents of the University of CaliforniaInventors: Laurence R. Brewer, Joseph Kimbrough, Joseph Balch, J. Courtney Davidson

Patent number: 6158244Abstract: Optical quality glass having a selected refractive index is produced by a two stage drying process. A gel is produced using sol-gel chemistry techniques and first dried by controlled evaporation until the gel volume reaches a pre-selected value. This pre-selected volume determines the density and refractive index of the finally dried gel. The gel is refilled with solvent in a saturated vapor environment, and then dried again by supercritical extraction of the solvent to form a glass. The glass has a refractive index less than the full density of glass, and the range of achievable refractive indices depends on the composition of the glass. Glasses having different refractive indices chosen from an uninterrupted range of values can be produced from a single precursor solution.Type: GrantFiled: March 16, 1998Date of Patent: December 12, 2000Assignee: The Regents of the University of CaliforniaInventors: John F. Poco, Lawrence W. Hrubesh

Patent number: 6134944Abstract: A system and method for preconcentrating, identifying, and quantifying chemical and biological substances is disclosed. An input valve directs a first volume of a sample gas to a surface acoustic wave (SAW) device. The SAW device preconcentrates and detects a mass of a substance within the sample gas. An output valve receives a second volume of the sample gas containing the preconcentrated substance from the SAW device and directs the second volume to a gas chromatograph (GC). The GC identifies the preconcentrated substance within the sample gas. A shunt valve exhausts a volume of the sample gas equal to the first volume minus the second volume away from the SAW device and the GC.Type: GrantFiled: April 29, 1999Date of Patent: October 24, 2000Assignee: The Regents of the University of CaliforniaInventors: Conrad M. Yu, Jackson C. Koo
