Patent number: 8501416Abstract: The present invention relates generally to microfluidic structures, and more specifically, to microfluidic structures and methods including meandering and wide channels. Microfluidic systems can provide an advantageous environment for performing various reactions and analysis due to a reduction in sample and reagent quantities that are required, a reduction in the size of the operating system, and a decrease in reaction time compared to conventional systems. Unfortunately, the small size of microfluidic channels can sometimes result in difficulty in detecting a species without magnifying optics (such as a microscope or a photomultiplier). A series of tightly packed microchannels, i.e., a meandering region, or a wide channel having a dimension on the order of millimeters, can serve as a solution to this problem by creating a wide measurement area.Type: GrantFiled: April 19, 2006Date of Patent: August 6, 2013Assignee: President and Fellows of Harvard CollegeInventors: Vincent Linder, Samuel K.

Patent number: 8268385Abstract: A method is provided for the determination a thickness error in a previously deposited layer using the reflection monitor signal of the currently-depositing layer. This thickness error is then used to compute corrections to the thickness of the currently-depositing layer and the next layer which corrects for the thickness error in the previous layer. The method is stable with respect to noise in the optical monitor signal. The technique is applicable for optical coating designs which are not necessarily quarter wave. The approach avoids the buildup of thickness errors from layer to layer and thus is applicable for very thick designs with many layers. Near the end of a currently depositing layer the monitor signal is used to fit the admittance of the base stack under the current layer. This establishes the parameters in an exact reflectance model used for the thickness monitoring of the current layer.Type: GrantFiled: May 14, 2008Date of Patent: September 18, 2012Inventor: William H.

Patent number: 8008068Abstract: A nonhemolytic sensor for determination of analytes in erythrocyte-containing biological fluids is disclosed that comprises an optical material having a deposit on a surface thereof, where this deposit includes an analyte-reactive reagent and a particulate means for suppressing hemolysis of erythrocytes in an erythrocyte-containing biological fluid, such as whole blood. Thus, a porous array of negatively charged particles, e.g., polymeric beads having a plurality of carboxylate surface groups, are disposed on a sampling surface of an optical sensor, and suppress hemolysis of erythrocytes coming into contact with the sampling surface. In the case of an optical sensor, such particles can simultaneously enhance reflectance of a light beam transmitted through the optical material to the sampling surface site.Type: GrantFiled: May 13, 2008Date of Patent: August 30, 2011Assignee: Light Pointe Medical, Inc.Inventor: Hiroshi Nomura

Publication number: 20110206830Abstract: A reverse interferometric method for the determination of the thickness of a layer of material employs a multi-wavelength light source which generates a light beam which comprises a time-variant series of different monochromatic wavelengths. The beam is reflected from the body of material being measured and is detected by a broad spectrum wavelength detector which produces a signal comprising a series of data points indicating the reflectivity of the sample as a function of the time-variant series of monochromatic wavelengths. A signal processor processes these data points to fit them to a model waveform, and the frequency of the model waveform is used to calculate the thickness of the body of material. Further disclosed are apparatus for carrying out the method and use of the method in a continuous process for the fabrication of thin film materials.Type: ApplicationFiled: February 19, 2010Publication date: August 25, 2011Applicant: United Solar Ovonic LLCInventors: Arun Kumar, William Thomas Sommerville

Publication number: 20110189380Abstract: A device for manufacturing a display device includes a deposition source; a deposition thickness calculator for calculating a deposition thickness of a deposition material deposited on a substrate; and a controller for controlling a power of a heater which heats the deposition source by comparing the deposition thickness calculated with a reference thickness. The controller controls the power of the heater either at least one time for each substrate on which the thin film is to be deposited or at regular intervals while the deposition material is deposited. Influence of measurement noise that is included in a quartz crystal sensor for measuring a deposition speed may be minimized, and distribution of deposition thickness of an organic light emitting material may be reduced, thereby increasing the yield of the deposition process and producing quality display devices.Type: ApplicationFiled: October 1, 2010Publication date: August 4, 2011Applicant: SAMSUNG MOBILE DISPLAY CO., LTD.Inventors: Won-Hyouk Jang, Eu-Gene Kang, Joo-Hwa Lee, Min-Jeong Hwang

Publication number: 20110151107Abstract: A method for real-timely monitoring thickness change of a coating film is disclosed. In the method, a coating module having a chamber and a film thickness-monitoring module containing an SPR optical fiber sensor, a light source, a light-receiving detector, and optical fibers are first provided. The optical fibers are used to connect the SPR optical fiber sensor with the light source and the light-receiving detector. The SPR optical fiber sensor has a sensing area and is arranged in the chamber. The light source provides the SPR optical fiber sensor with light. Then, a substrate is put into the chamber. While coating process is performed on the substrate, a film is also formed on the sensing area of the SPR optical fiber sensor. The light-receiving detector receives signals output from the sensing area of the SPR optical fiber sensor and then outputs signals of light-intensity change.Type: ApplicationFiled: April 22, 2010Publication date: June 23, 2011Applicant: Forward Electronics Co., Ltd.Inventors: Yu-Chia Tsao, Chung-Pei Lee, Ko-Shao Chen, Jia-Huey Tsao, Chun-Chih Lin, Ren-Kun Liang

Patent number: 7927651Abstract: There is provided a biosensor capable of increasing a detecting sensitivity of a target substance of glutamate, by using a nano wire having excellent electrical characteristics and by immobilizing a receptor of glutamate to be detected on a substrate which is disposed between a nano wire and another nano wire and a method for manufacturing the same. The biosensor for detecting glutamate according to the present invention can be manufactured with an arrangement in which the nano wire is selectively arranged on a solid substrate in a matrix. Since this biosensor can prevent the degradation of the nano wire in the electrical characteristic, it can sensitively detect glutamate even through a small amount thereof is contained in a food so that it can be effectively used in detecting the food additive existing in the processed foodstuffs.Type: GrantFiled: April 4, 2007Date of Patent: April 19, 2011Assignees: Seoul National University Industry Foundation, Mitech CorporationInventors: Seung-Hun Hong, Byung-Yang Lee, Dong-Joon Lee

Patent number: 7901945Abstract: A system and method for recognition of images may include the use of alignment markers. The image recognized may be a pattern from an array, a character, a number, a shape, and/or irregular shapes. The pattern may be formed by elements in an array such as an identification marking and/or a sensor array. More particularly, the system and method relate to discriminating between images by accounting for the orientation of the image. The size and/or location of alignment markers may provide information about the orientation of an image. Information about the orientation of an image may reduce false recognitions. The system and method of image recognition may be used with identification markings, biosensors, micro-fluidic arrays, and/or optical character recognition systems.Type: GrantFiled: July 16, 2008Date of Patent: March 8, 2011Assignee: Board of Regents the University of Texas SystemInventors: Jason E.
