  • Publication number: 20090119615
    Abstract: A method and device for controlling the scrolling of pages on a touch screen of a hand-held electronic apparatus. A liquid crystal display and a touch panel having a larger area than that of the liquid crystal display are overlapped and combined with each other. The overlapped region is defined as a first touch zone, while the non-overlapped region is defined as second touch zones and a third touch zone. Next, a user determines whether a scroll is shown in the picture of the display. If the user determines that a scroll is shown in the picture, a sliding path is sensed by the second touch zone, and the user controls the page to scroll upwards or downwards in the picture based on the sliding path. The first touch zone is pressed to thereby perform the function of the selected page. If the user determines that a scroll is not shown in the picture, a sliding path is sensed by the third touch zone, and the user controls the page to slide rightwards or leftwards in the picture based on the sliding path.

  • Publication number: 20090085886
    Abstract: A method for performing a view switching function of a handheld device with a touch screen is provided. The handheld device has an LCD panel and a touch panel. The touch panel has a touch region larger than a display area of the LCD panel. The touch panel has a main touch region overlapping the LCD panel, and an assistant touch region surrounding but not overlapping the LCD panel. The method includes (a) when the touch panel detects a presence of an object, determining whether the main touch region or the assistant touch region is touched; (b) when it is determined that the main touch region is touched, and it is determined that the object slides to the assistant touch region, switching from a first view to a second view displayed on the LCD panel; and (c) when it is determined that the assistant touch region is touched, and it is determined that the object slides to the main touch region, switching from a third view to a fourth view displayed on the LCD panel.

  • Publication number: 20090079704
    Abstract: A method and an apparatus for inputting operation instructions using a dual touch panel of a mobile communication device are provided. When the user's finger touches the second touch panel of the mobile communication device, the second touch panel detects whether there is a slide path. If no slide path is detected in a predetermined time, a no slide signal will be output. A stop signal as a confirmation key will be output after the touch on the second touch panel ends. If there is a slide path, then it is determined whether the slide path is a one-dimension or two-dimension slide path. If a one-dimension slide path is detected in a predetermined time, a slide direction signal will be output. A stop signal as a direction key will be output after the touch on the second touch panel ends. If a two-dimension slide path is detected, the slide path in each direction is recorded.

  • Patent number: 7507534
    Abstract: The present invention discloses a method for rapid assessment of lung cancer therapy efficacy in a few days instead of weeks by conventional imaging methods. This method can also be used to detect relapse of the cancer and to improve the current TNM cancer staging method for more accurate prognosis. The rapid assessment of therapy efficacy is based on detecting circulating cancer cells in body fluid with high positive detection rate. The high positive detection rate is achieved by using qPCR amplification of multiple marker genes identified by in silico search of DNA sequence database. This invention also discloses a scoring method to calculate the cancer cell load based on qPCR results to correlate the amount of circulating cancer cells in lung cancer patients and predict the treatment outcomes.
