Patent number: 11202590Abstract: Disclosed is a system which adds biochemical sensitivity to a standard biopsy needle such that the practitioner is provided immediate feedback on the metabolism and physiology of tissue in the local environment. Disclosed is a sensor integrated biopsy device for in situ and real time tissue analysis. The sensor integrated biopsy (SIB) needle system will enable biopsy teams to measure local tissue biochemistry in real time during biopsy procedures, adding a valuable new set of parameters to augment and extend conventional image-guided procedures.Type: GrantFiled: June 1, 2017Date of Patent: December 21, 2021Assignee: Intelligent Optical Systems, Inc.Inventors: Jesus Delgado Alonso, Robert Lieberman, David Berry

Patent number: 7650051Abstract: Distributed fiber optic chemical and physical sensors can provide a relatively highly uniform response over the length of the fiber by, for example, varying such properties as the core/cladding index of refraction ratio to compensate for the non-linearity in sensitivity. The phenomenon of spatial transient over a length of a fiber introduces such a nonlinearity that can be compensated for by varying at least one parameter of the optical fiber.Type: GrantFiled: August 21, 2007Date of Patent: January 19, 2010Assignee: Optech Ventures, LLCInventors: Robert A. Lieberman, Claudio O. Egalon

Patent number: 7551810Abstract: A fiber optic sensor for sensing the presence of an analyte has a plurality of optical fibers each of which has at least one analyte sensing segment and one or more low loss lead portion, where the optical fibers are disposed on the periphery of a fiber carrier. The analyte sensing segments may be disposed in an offset relationship to provide continuous detection over a desired distance or they may be spaced apart to provide detection at selected locations. More than one set of optical fibers with sensing segments may be combined to provide detection of multiple analytes. Multiple fiber carriers allow each segment or the grouped sets of segments to be coupled together over a distance either in offset relationship or in spaced apart relationship.Type: GrantFiled: September 22, 2005Date of Patent: June 23, 2009Assignee: Optech Ventures, LLCInventors: Alexander Berger, Robert A. Lieberman

Patent number: 7518724Abstract: Image data is acquired, processed, and/or displayed in accordance with an embodiment of the present disclosure to display, monitor, and/or demonstrate the progress of an experiment substantially in real-time and with high sensitivity. In one embodiment, at least one time-resolved value of spatially distributed polarization change data is provided and displayed. Advantageously, real-time processing and display of data is provided such that discussion and collaboration about the experiment may occur, time-resolved data is not lost, and resources are not wasted.Type: GrantFiled: December 29, 2005Date of Patent: April 14, 2009Assignee: Maven TechnologiesInventors: William R.

Patent number: 7496267Abstract: A photosensitive sol-gel film containing an organometallic photosensitizer is deposited on the oxide containing surface layer of a silicon substrate. A pattern of white or ultra violet light incident to the photosensitive sol-gel film results in the unbinding of the photosensitizer from the exposed regions of the sol-gel film. A subsequent succession of first and second heating steps results in, first, the removal of the photo sensitizer constituents from the exposed regions of the sol-gel film and, second, the removal of the organic constituents from the exposed regions, resulting in regions doped with a metal oxide with non linear optical properties, such as semicondutive, etc. properties. Optical switches, couplers, waveguides, splitters, interferometers wavelength division multiplexer, Bragg gratings and more can be fabricated. A glass substrate also may be employed, instead of a silicon, in which case a separate silicon oxide surface layer is unnecessary.Type: GrantFiled: October 16, 2007Date of Patent: February 24, 2009Inventors: Edgar A. Mendoza, Lothar U. Kempen, Robert A. Lieberman

Publication number: 20070286547Abstract: Distributed fiber optic chemical and physical sensors provide a relatively highly uniform response over the length of the fiber by, for example, varying such properties as the core/cladding index of refraction ratio to compensate for the non-linearity in sensitivity due for example to the loss of higher order modes in multi-mode fibers. The variation of the ratio changes the absorption coefficient of the fiber and can be used to compensate for any non-linearity in response. Other techniques for compensation also are disclosed. In particular, the invention enables compensation for the duration of the spatial transient by varying a parameter relating to the fiber.Type: ApplicationFiled: August 21, 2007Publication date: December 13, 2007Inventors: Robert Lieberman, Claudio Egalon

Publication number: 20070245772Abstract: A partially modified photosensitive monolithic oxide glass apparatus formed through photolithographic imaging. The apparatus may be either a volume apparatus or a layer apparatus. Both types of apparatus may be used to diffuse light in predetermined directions or shapes. The monolithic oxide glass apparatus is capable of withstanding temperatures well beyond glass transition temperatures of plastic light shaping devices and can be formed in convex or concave surfaces through conventionally molding grinding or polishing techniques and can be coated by hot-coating techniques.Type: ApplicationFiled: October 30, 2002Publication date: October 25, 2007Inventors: Robert Lieberman, Edgar Mendoza, David Mintzer
