Abstract: A wireless transmission system suitable for a large space and a method thereof are provided, which are applied to a wide space having a main power switch connected with power lines. Each of the power lines is respectively connected to a power outlet. A wireless base station is disposed beside the main power switch, and its required power is supplied by the main power switch. A signal line is respectively disposed along each power line, wherein one end of each signal line is connected to the wireless base station while the other end is connected to a wireless signal antenna. Each of the wireless signal antennas is respectively mounted on the corresponding power outlet. When wireless signals are sent from the wireless base station, they are transmitted via signal lines to anywhere in the wide space, and then sent out via the antennas to be received by mobile communication devices.

Abstract: A circuit layout system for automatically indicating items to wait for modified and method thereof are provided, wherein a set of items to wait for modified recorded on an amendment list is stored on the circuit layout software; the set of items to wait for modified is compared with the circuit diagram via the circuit layout software to indicate to the user the number of items to wait for modified; parts that need to be modified are indicated to the user during modification, such that automatic indication of the items to wait for modified can be achieved, thus avoiding the circumstance that some items to wait for modified are not modified completely due to the negligence of the user.

Abstract: A remote controller accesses via a connection control data from an appliance to be controlled. The remote controller includes a connection interface, a control unit, an input keypad and a remote signal output unit. When a user intends to remotely operate the appliance, first the connection interface needs to be inserted to a connection slot of the appliance, allowing the control unit to read the control data for remotely controlling the appliance. Then, when the user uses the input keypad to operate a function of the appliance, the control unit transmits an operational instruction from the input keypad and the control data to the remote signal output unit where a control command is generated and transmitted to the appliance such that the appliance can execute the function corresponding to the control command.

Abstract: A method of alerting incoming call for wireless telephone apparatus includes the procedures of: receiving a calling signal sent from a wireless telephone apparatus by a wireless transceiver module of a computer enabled platform, confirming the phone identification data in the calling signal matching a preset comparison data, and switching a display condition of a display element of the computer enabled platform. Hence users can confirm whether an incoming call arrived the wireless telephone apparatus through the alteration of the display element to avoid missing important information.

Abstract: A keyboard with automatic adjusting key intervals can adjust the key interval values and the key frame edge values of a keyboard according to the detected contour scope of a user's hands. The adjusted keyboard is displayed on a touch screen so that the user can perform keyboard operation more smoothly on the keyboard that matches the size of his/her hands.
