  • Publication number: 20140007002
    Abstract: A calculation control method is used for an electronic device. The electronic device includes a storage unit storing a number of arithmetic equation models. The method includes the following steps. Sense handwritten touch input on a touch sensing unit by a user. Generate signals associated with the user's handwritten touch input. Display the handwritten content according to the generated signals. Recognize the handwritten content of the user, and convert the recognized handwritten content into an arithmetic operation if the recognized handwritten content matches one of the arithmetic equation models stored in the storage unit. Calculate a result of the arithmetic operation, if the recognized handwritten content matches one of the arithmetic equation models. And display the calculated result to the user.

  • Publication number: 20110285644
    Abstract: An electronic device includes a display unit and a touch panel. The display unit includes at least two display areas, wherein each of the display areas has a unique operation frequency. The touch panel is installed in front of the display unit and includes at least two touch areas corresponding to the display areas, each of the touch areas is scanned with a unique scan frequency corresponding to the unique operation frequency of the corresponding display area. Through partition design for the GUI, the electronic device can respectively scan the touch areas, which replace the existing scanning method to scan the whole touch panel, and it is more efficient.

  • Publication number: 20110078629
    Abstract: An electronic device is provided. The electronic device includes an input unit, a display unit and a storage unit. The storage unit stores a product function list and a plurality of UI profile files. Each of the UI profile files defines one display format. A UI (user interface, UI) establishing module activates a function of the electronic device for establishing a UI. A product function list loading module loads the product function list from the storage unit. A product function list parsing module parses the loaded product function list. A user interface profile file loading module selectively loads the UI profile file from the storage unit. A user interface generation module displays the parsed product function list on the display unit according to the display format of the selective UI profile file, and links the generated menu interfaces to generate a series of user interfaces.

  • Publication number: 20090310621
    Abstract: A method to classify the network speed disclosed is utilized to distinguish between an advanced-level user bandwidth and a general-level user bandwidth for users whose devices are connected by the access point. The method includes selecting a bandwidth-distribution rule of the access point, and distributing the total bandwidth supported by the access point according to the selected bandwidth-distribution rule. The bandwidth-distribution rule is selected from a ratio-distribution rule, a highest-band restriction rule, and a lowest-bandwidth restriction rule. The bandwidth distributed to each advanced-level user is larger than the bandwidth distributed to each general-level user.

  • Publication number: 20040052360
    Abstract: An equipment for automatically screening and filtering a disturbance for an incoming phone call includes a screening data bank, a register device, a comparing module, and an output device. The screening data bank is used to store a screen data, and the register device is used to store the phone number information of the incoming phone call, when the phone transmitting device calls to the phone receiving device requesting for signal connection. Then, the comparing module automatically makes a comparison between the screening data and the phone number information of the incoming phone call. When the comparison results in a match, the output device issues a signal indicating that the line is busy to the phone transmitting device for rejecting the signal connection. When the comparison does not result in a match, the output device issues a signal for receiving the phone call, so as to inform the user to receive the phone call.
