    摘要： A system and method effective to provide content to a user. The system may include a sound device, a smart phone, and a processor. The sound device may output a modulated code. The sound device may include a processor effective to generate a periodic wave based on a code and a speaker in electrical communication with the processor. The speaker may output the modulated code based on the code. The smart phone may receive and demodulate the modulated code to reproduce the code. The smart phone may send the code to a processor. The processor may receive the code, determine content associated with the code, and send the content over the network to the smart phone. The smart phone may further receive the content and display the content on a display.

    摘要： A mobile communication terminal having QWERTY keys and a method for outputting Dual Tone Multi-Frequency (DTMF) signals thereof are disclosed. The user inputs information including alphabetic characters that is requested by a directory system, while viewing the alphabetic characters marked on the QWERTY keys. The mobile communication terminal outputs DTMF signals of symbols marked on the input QWERTY keys identical to the DTMF signals of the corresponding symbols of keys arrayed in a conventional 3x4 key array format. The alphabetic keys of the QWERTY keys output DTMF signals identical to those of the keys of the 3x4 array format in an alphabet input mode. Therefore, the user can easily input information requested by the directory system while viewing the symbols marked on the QWERTY keys, without requiring the user to memorize the array of alphabetic characters of the 3x4 key array format.

    摘要： The telephone of the present invention is a push button type telephone whereby a DTMF signal of a first one-touch dial table is sent out in accordance with operation keys input in the general line mode and a DTMF signal of a second one-touch dial table is sent out in the private branch exchange mode. A signal sent out from a telephone in the private branch exchange mode represents a character string composed of one or more characters, starting with a character selected from a particular character group like such a less frequently used (DTMF) char-acter as 'A', 'B', 'C' or 'D'. A function table on the part of a private branch exchange establishes ties between a character string starting with a character included in the aforementioned character group and a service function.

    摘要： A method and apparatus for generating dual tome multiple frequency signals employing a low fre­quency quartz oscillator, wherein a phase accumula­tion dual tone multiple frequency generator is com­prised of a low frequency quartz oscillator. Two phase selectors are connected to produce digital phase signals in response to a signal input. Two phase accumulators, each composed of an adder and a register, are connected to accumulate the phase sig­nals. Two ROM based sine wave tables are addressed by the outputs of the accumulators. An adder adds the outputs of the ROMs, and a D/A converter pro­duces an analog output from the output of the adder.
