An electronic paper device is provided. The electronic paper device includes a common electrode layer, a plurality of pixel electrodes, an electrophoretic ink layer, a conductive layer, a touch panel, and a processing unit. The electrophoretic ink layer is electrically connected between the plurality of pixel electrodes and the common electrode layer. The conductive layer and the common electrode layer respectively have a different voltage. When the user touches the electronic paper device and causes the conductive layer contacts a pixel electrode corresponding to the touch position, then the pixel electrode obtain the voltage of the conductive layer and an electric field is formed between the pixel electrode and the common electrode layer. This causes the color to change at the position that is corresponding to the touched position.

A bus stop board for advertising includes a communicating unit, a storage unit, an input unit, a control unit, a display unit, and a short message service control unit. The control unit obtains available advertisements stored in the storage unit in response to a passenger's first signal into the input unit, and receives a selection of advertisements made by a passenger in response to a second signal. The display unit displays the selected advertisements and a user interface for the passenger's telephone number. The short message service control unit generates a data package for each selected advertisement and transmits the data package to a user terminal with the input telephone number. A related system is also provided.

A bus stop sign capable of providing detailed bus schedules includes a storage unit, a detecting unit, a communicating unit, and a control unit. The storage unit pre-stores a table recording identifications of a plurality of mobile terminals, identifications of a plurality of bus terminals, and stop information of the bus stop sign along bus routes of the bus terminals. If the identifications of the mobile terminals obtained by the detecting unit match one or more identifications recorded in the table, the control unit obtains identifications of bus terminals recorded in the table corresponding to the obtained identifications, and controls the communicating unit to transmit the obtained identifications to the server. The server determines the current location of the nearest bus terminal travelling toward the bus stop sign and feeds back the current location of the nearest bus terminal to the mobile terminal. A related sever is also provided.

A method for printing and faxing is used for an electronic device storing a relationship table. The relationship table records a mapping relationship between touch input and a plurality of commands. The method comprises the following steps. Display an electronic file selected by a user. Then generate signals in response to user's touch input on the displayed electronic file. Determine whether a command associated with the touch input of the user is a printing command or a fax command according to the generated signals and the relationship table. Retrieve circled content of the displayed electronic file circled by the user when the command associated with the touch input of the user is the printing command or the fax command; and send the circled content to a printer or send the circled content to a fax machine selected by the user. An electronic device using the method is also provided.
摘要:
An electronic device includes a storage unit, a touch input unit, a display unit, and a processor. The storage unit stores a relationship table recording a mapping relationship between touch inputs and a number of commands associated with the touch inputs. The touch input unit generates signals in response to user's touch input. The processor includes a control module and an identification module. The control module controls displaying the sensed handwritten content on the display unit. The identification module recognizes the touch input of the sensed handwritten content and identifies if the touch input of the recognized handwritten content is associated with a command according to the signals and the relationship table. The control module also controls the electronic device to execute the associated command.

A remote control apparatus for controlling a plurality of remote controllable appliances includes a housing, an infrared signal receiving window and an infrared signal transmitting window defined in the housing. The remote apparatus determines the selected appliance and the selected function based upon a wireless signal carrying an identification transmitted by the mobile terminal, determines an infrared remote control code, and emits an infrared signal carrying the infrared remote control code. A light directing element received in the housing directs the infrared signal emitting by the infrared transmitting unit and the infrared remote control signal from the attached remote control to exit the housing through the infrared signal transmitting window, thereby controlling the selected appliance to execute the selected function.

A luminance adjusting circuit includes an LED module, a switch module and a processing unit. A table equating luminance levels and average current values is pre-stored. The processing unit includes a judging and executing module and a signal generating module. The judging and executing module achieves a desired luminance level according to trigger signals generated by a button. The signal generating module produces timing signals to turn on and turn off the switch module periodically, thereby achieving an average current value to adjust the luminance level of the LED module to the desired level.
