  • Publication number: 20090042547
    Abstract: The present invention relates to a mobile terminal and a method of controlling an operation of the same. The method of controlling an operation of a mobile terminal includes driving a web browser and access a specific website, displaying a web page provided by the specific website, and when any one of numeric enter keys is pressed, displaying an entry window for inputting a website address. Accordingly, a user interface of an intuitive and natural control fashion can be provided to a user.

  • Publication number: 20080273020
    Abstract: The present invention relates to a mobile communication device, method and computer program product for controlling a displayed screen using a rotary input device and an operating method thereof. The mobile communication terminal according to an embodiment includes a first input key, a second input key, a third input key, and a controller The first input key generates a first signal when the first input key is turned. The second input key generates a second signal when the second input key is activated after the first signal is generated. The third input key generates a third signal when the third input key is activated after the first signal is generated. The controller controls a predetermined operation on a displayed screen based on at least one of the first signal, the second signal, and the third signal.

  • Publication number: 20070090166
    Abstract: Microfluidic devices for cell culturing and methods for using the same are disclosed. One device includes a substrate and membrane. The substrate includes a reservoir in fluid communication with a passage. A bio-compatible fluid may be added to the reservoir and passage. The reservoir is configured to receive and retain at least a portion of a cell mass. The membrane acts as a barrier to evaporation of the bio-compatible fluid from the passage. A cover fluid may be added to cover the bio-compatible fluid to prevent evaporation of the bio-compatible fluid.

  • Patent number: 7043382
    Abstract: A low voltage swing bus analysis method using a static timing analysis (STA) tool, which provides simple and accurate timing analysis verification. The low voltage swing bus analysis method is used in a static timing analysis (STA) tool. The STA tool receives a design file which executes the timing verification program then extracts the timing model for each cell, present in a design file during execution of the timing verification program, and calculates a timing for each node. The STA tool extracts a timing model for a sense amplifying flip flop, among cells present in the design file during execution of the timing verification program, from execution of a subroutine and calculating a timing for each node connected to the sense amplifying flip flop. The STA tool outputs the calculated timings.
