20100244324 | METHODS AND APPARATUS FOR RAPID IMPRINT LITHOGRAPHY - A mold for imprinting a patterned region by imprint lithography is provided with a peripheral groove around the patterned region. The groove is connected, as by channels through the mold, to a switchable source for gas removal to prevent bubbles and for the application of pressurized gas to separate the mold and substrate. In use, the mold is disposed adjacent the moldable surface and gas is withdrawn from the patterned region through the groove as the mold is pressed toward and into the moldable surface. At or near the end of the imprinting, the process is switched from removal of gas to the application of pressurized gas. The pressurized gas passes through the groove and separates or facilitates separation of the mold and the moldable surface. | 09-30-2010 |

20110042861 | METHODS AND APPARATUS OF FIELD-INDUCED PRESSURE IMPRINT LITHOGRAPHY - An improved method of imprint lithography involves using field-induced pressure from electric or magnetic fields to press a mold onto a substrate having a moldable surface. In essence, the method comprises the steps of providing a substrate having a moldable surface, providing a mold having a molding surface and pressing the molding surface and the moldable surface together by field-induced pressure from electric or magnetic fields to imprint the molding surface onto the moldable surface. The molding surface advantageously comprises a plurality of projecting features of nanoscale extent or separation, but the molding surface can also be a smooth planar surface, as for planarization. The improved method can be practiced without mechanical presses and without sealing the region between the mold and the substrate. | 02-24-2011 |
20110155060 | Method And Apparatus To Apply Surface Release Coating For Imprint Mold - A surface coating apparatus for preparing a work piece having a working surface for imprint lithography, wherein the work piece comprises either a mold or a substrate. The apparatus includes a vacuum chamber and a generator to produce chemical reaction radicals for cleaning the working surface. The generator may be located inside said vacuum chamber and connected to an inner surface of said vacuum chamber or external to the vacuum chamber and connected thereto via suitable couplings. A fixture within the vacuum chamber is configured to hold the work piece with the working surface accessible by the chemical reaction radicals, and a means is provided for depositing a molecular layer of surfactant on the working surface inside the vacuum chamber. | 06-30-2011 |
20110180965 | FAST NANOIMPRINTING APPARATUS USING DEFORMALE MOLD - The invention disclosed apparatuses and methods to do nanoimprint lithography using a deformable mold. Generally, the apparatus has a chamber with a transparent section on its top wall, which is capable of vacuuming and pressurizing. The deformable mold fixed firmly onto a hollow mold holder around its full periphery is attached to top inner surface of the chamber and positioned underneath the transparent section. The central area of the mold is freely accessible from underneath through the opening of the mold holder. An enclosed volume referring to mold mini-chamber is formed between the mold/holder and top wall of the chamber. Inside chamber, a stage assembly is installed. A chuck to vacuumly hold a substrate is mounted on top of the stage assembly. At beginning of the imprinting, the substrate with a layer of resist is positioned underneath the mold at a predetermined gap between them. Then, the substrate is moved up to contact with the mold either under vacuum or under atmosphere. The substrate and mold may be pressed further by introducing higher pressure inside the chamber. After consolidating the resist, the substrate is separated from the mold by either direct pull-down enabled by stage movement or deforming the mold enabled by differential pressure between the mold mini-chamber and the bulk volume of the chamber, or mixing of both. | 07-28-2011 |
20130082874 | METHODS FOR ROAD SAFETY ENHANCEMENT USING MOBILE COMMUNICATION DEVICE - Methods for road safety enhancement use mobile communication device (MCD) onboard vehicle to share traveling data through inter-vehicle communication broadcasting, perform road hazard warning, enhance road navigation, and provide autonomous road assistance. The methods have a variety of vehicle status data, such as moving data, steering data, or indicator data, obtained through GPS or image capturing and recognition of instrument cluster of vehicle. The image capturing and recognition allows to get speed data from indication of speedometer, indication of left or right turn signal, steering action data corresponding to steering wheel rotation, and light-on indication of system status indicators. To facilitate that, the MCD may be placed in front of steering wheel, and, if applicable, also in coupling with movement of steering wheel. The MCD may perform relative positioning map-matching lane correlation and GPS-update-interval speed positioning to improve data quality regarding vehicle moving status. | 04-04-2013 |
20130085887 | METHOD AND SYSTEM FOR FINANCIAL CARD TRANSACTION VERIFICATION - The invention is aimed to verify credit card transaction or any transaction using similar payment mechanism through joint effort of cardholder and card issuer. In accordance with the invention, principle of method to verify financial card transaction is to use a mobile communication device (MCD) carried by cardholder to maintain an event record in a record list every time when cardholder starts a payment using a financial card, then, having wireless communication network address of the MCD in account record associated with the financial card, account server of corresponding card issuer notifies the MCD a newly occurred activity regarding to payment transaction upon the account, after that, the MCD searches the record list trying to establish a match between the newly received activity notice and an existing event record that both the event record and the notice have substantially simultaneous occurring time, thus being considered for the same transaction. | 04-04-2013 |
20130314226 | METHOD AND SYSTEM USING MOBILE COMMUNICATION DEVICE TO IMPROVE HOME SAFETY - In accordance with the invention, a mobile communication device (MCD), preferable a mobile phone, intercepts a RF signal indicating a remote operation occurred on home equipment and starts safety monitoring process to observe situation progress following receiving the RF signal. When certain condition, for example time-up of a timer or leaving-site based on GPS location, is found satisfied, the MCD alerts user that a potential safety concern is raised up and prompts user to take appropriate action to prevent the potential safety concern from evolving into really occurred danger or disaster. The RF signal may be sent by a remote control or a remote sensing device coupled with operation of home equipment. Two examples respectively for safety enhancement of using cooking range and safety enhancement of accessing garage door are disclosed as implementation examples of the method and system using MCD to enhance home safety. | 11-28-2013 |
20140281952 | INTERACTIVELY VIEWING MULTI DOCUMENTS ON DISPLAY SCREEN - A computer implemented method for viewing multi document interactively involves viewing two or more documents concurrently displayed on display screen and bringing a content portion of one document into corresponding view region on display screen when a selectable link embedded in another document, which represents a reference to the content portion, is selected by user interface input acted thereupon. Each document is hosted by a browser engine to display on a display region on display screen. A browser engine host performs as a coordination and information center of the browser engines. When a selectable link is selected, the hosting browser engine submits a request containing identification of the link to the browser engine host. The browser engine host processes the request and, accordingly, direct the browser engine destined to act thereupon to bring the referred content into viewable area of corresponding display region. | 09-18-2014 |
