Abstract: A method to reduce the amount of black in an image is disclosed. The method uses a computer to reduce or eliminate the amount of black in an original digital image. In the present invention, every three adjacent pixels are processed as a set, and the intensities of the RGB values are increased, respectively.

Abstract: A method of reducing the amount of black in an image is disclosed. The method is using a computer to reduce the amount of or eliminate the black in an original digital image. The major procedure is to increase the pixels of the original digital image (by four or nine times) and then change the color information of the pixels.

Abstract: A method of putting identification codes in a document is disclosed. The method adds a speech-purpose print code in a document such that an OID pen can emit sound after the OID pen reads the speech-purpose print code. The software program first acquires the position of each word in the document and then automatically puts a speech-purpose print code corresponding to each word in the position of each word so that a user can rapidly generate a document with speech-purpose codes.

Abstract: A method and a system for voice communication, especially for a user who has voice or speaking problems, are disclosed. The method requires a communication sheet and a digital voice signal processing device. The communication sheet comprises a plurality of communication units and a plurality of function units for a user to click with the digital voice signal processing device. The plurality of function units comprise a whole sentence unit, and the method comprises a method for performing a function of emitting the sound of a whole sentence, which comprises the following steps: receiving sounds of words selected by the user; searching a voice file according to each of the sounds of words; receiving a command generated by the user's clicking the whole sentence unit; and playing voice files in order.

Abstract: A method of editing communication sheets comprises providing a picture/text editing interface; providing a dividing function for communication sheet; providing a expression (s) database, a picture database and a voice database; providing a correlation searching function; providing expression (s) insertion function; providing picture insertion function; providing language assigning function; and providing a output file generating function. The method also handles multiple languages and can change the language of expression (s) or voice with a rapid manner.

Abstract: A method of learning a second language through the guidance of pictures that enables users to learn multiple languages through computers. After users input a plurality of words, a picture/text interface will display the plurality of input words, a plurality of output words, and a plurality of pictures. The plurality of output words represent the plurality of input words in another language, and the plurality of pictures represent the plurality of input words.

Abstract: An input device with a page turning functionality is used with a set of communication cards, and includes a casing, a clip provided to hold the communication cards together, a processor, a touchpad, a memory, a speaker and a target page reminding device. When at least one communication block on a communication card is pressed, the processor generates a target page signal. The target page reminding device will remind a user to turn to the corresponding page according to the target page signal.

Abstract: A learning device with page indicators includes a case, a touch pad, an electronic control unit and multiple page indicators. When each learning card is placed on the touch pad, the position next to the page actuating mark of each learning card has one corresponding page indicator. When the page actuating mark is touched, the corresponding page indicator is activated.

Abstract: A main computer with multiple operating devices enables multiple users to manipulate the main computer.

Abstract: A system includes a host computer and operational devices. The operational devices are connected to the host computer by a connection device and utilizable by users. The host computer is used for executing an interactive program and a control manner specifying program. The control manner specifying program has a first routine for distributing the operational instructions of the interactive program to at least two users so that the interactive program is used by at least two users, and a second routine for changing the distribution method of the operational instructions of the interactive program to the users.

Abstract: An interactive learning software program includes a teaching computer, a plurality of operational devices and a notebook computer. The teaching computer is used for executing at least one interactive learning software program. The plurality of operational devices are used by the plurality of students and output an operational instruction to the teaching computer to use the interactive learning system. The notebook computer is used by the teacher, and the notebook computer is capable of executing an interactive control software program to output a control instruction to the teaching computer so that the interactive learning software selectively accepts the operating instruction from the operational device.

Abstract: An electronic switch is has a receiver for receiving external switch signal and to producing corresponding switch control signal. A decoder us provided to receive switch control signal from the receiver and to produce corresponding decoding signal containing a switch identification code. A memory stores at least one switch identification code, each switch PIN code corresponding to a respective switch element. A processor is provided to compare switch identification code from the decoder with switch PIN code in the memory and to turn on the corresponding switch element when the switch identification codes are matched. The processor has a learning mode for writing every received switch identification code from the decoder into the memory and corresponding every written switch PIN code to the at least one switch element respectively.

Abstract: An input device with page turning used with a set of communication cards, and driven to record input voice, to reproduce recorded voice signal or send recorded voice signal to an external computer through a transmission line when the user presses on one of the communication cards, the input device including a casing having an operating surface area, which holds the communication cards, a clip provided at the casing to hold the communication cards for enabling the communication cards to be taken out and replaced.
