  • Patent number: 9274609
    Abstract: Example apparatus and methods concern improved input of radicals. Example apparatus and methods facilitate more efficiently inputting Chinese radicals using a touch screen. One example method includes displaying a labeled soft key on a touch screen device. The label may represent all or a portion of a radical. The example method includes accepting a touch input associated with the soft key and then taking an action based on the label and the touch input. The action may include inputting a radical or updating the display on the touch screen. Updating the display may facilitate iterative and intuitive progress through radical construction leading to radical selection and input.

  • Patent number: 7574237
    Abstract: A system and method to obtain a nickname for records, particularly records having number fields. A set of triplets is identified in a record 401. Criteria, at least at a strict level, is set to establish that used triplets are many, and hard to avoid 403. Using this criteria, triplets may be processed in order 405. Each triplet is checked against the criteria 407. Avoidance of the used criteria, i.e. that the current triplet is not used, enables the triplet to be associated with the record 413. Failure to avoid the used criteria enables a loop to continue if the exit criteria 409 is not met. A next triplet is obtained 410 if the inner loop continues. Otherwise, a check to get a more relaxed used triplet criteria is made 411. If a relaxed used triplet criteria is available 411, the relaxed used triplet criteria (having fewer used triplets) is used 415, and an outer loop continues with processing of the list of triplets 405 again. Otherwise, a triplet may manually be associated with the record 417.

    Abstract: A mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the “*” button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance).

  • Patent number: 6681002
    Abstract: A data entry and processing system providing for simple two stroke entry of numerous auxiliary alpha-numeric data in addition to the single stroke entry of numeric data, using conventional data entry keys. The key array includes a set of radial direction indicator keys that are used with the conventional keys to select and enter a given alpha-numeric data item. An LCD display, a pre-programed micro-processor and other electronic components are included to display the data entries, as well as to convert entered data signals to the necessary DTMF tones for telecommunication or ASCII codes for computer data entries. The system is simple for use by ordinary users, and all electronic components are standard, minuscule in size, small in number, low in power need and low in cost. It is particularly adaptable for miniaturized device application.

  • Patent number: 6594348
    Abstract: The present invention relates to a voice browser 110 and a method at a voice browser, the voice browser 110 being arranged at a server 120 connected to the Internet 130 and responsive to Dual Tone MultiFrequency (DTMF) tones received from a telecommunications network 150. The voice browser is responsive to different sets of predetermined DTMF tones, one set dedicated for voice browser functions and another set dedicated for HTML application functions. The voice browser 110 synchronises the possible DTMF tones that can be accepted for a certain browsed part of an HTML page.

  • Publication number: 20020136371
    Abstract: A keypad for entering letters includes an array of keys with each key being assigned to at least one letter of an alphabetical system based on the frequency of occurrence of the least one letter in a typical body of written work. The alphabetical system comprises at least one most-frequently-occurring letter that is entered by activation of the same key twice and at least one less-frequently-occurring letter that is entered by activation of two different keys.

  • Patent number: 6346894
    Abstract: A method and system for intelligent text entry on a keypad. First, a user selects a key on a keypad. Then, an application predicts which character of those corresponding to that key is intended by the user. The predicted character is then presented to the user for confirmation. If the user confirms the selection, the character is stored. If the user rejects the character, the application presents a new character to the user until a character is finally confirmed. It is only when the predicted character is not the intended character that the user is required to iterate through character choices.

  • Patent number: 6282272
    Abstract: The present invention provides a method and interface for browsing the internet using a telephone circuit having keys for generating DTMF codes. The interface includes a memory and a processor and is coupled to the telephone circuit and display. The interface receives a first DTMF code requesting access to the internet and, in response to the first DTMF code, loads a Web browser in its memory. The interface then receives a second DTMF code from the telephone circuit and converts the second DTMF code into a Web browser command using an interpretation protocol. The Web browser command is then executed using the interface, thereby enabling a user to access the internet via manual operation of the keys of the telephone is circuit.

  • Patent number: 6236724
    Abstract: A method of generation and detection of acoustic signals carrying alpha-numeric data for reducing the effects of noise and thereby improving signal transmission without the need to boost the power of the signal. In accordance with one aspect of the invention, a special DTMF acoustic signal consisting of a combination of two frequencies will be generated for the representation of a particular alpha-numeric character that will be similar to the standard DTMF tone. The difference between the amplitudes of both frequencies varies during the time of generation of the DTMF tone in such a way that both signals will arrive at a final destination detector, i.e., an interactive voice response board, at least for a portion of the generation time, at a relatively similar amplitude, thereby substantially increasing the probabilities of being recognized as a DTMF signal.

  • Patent number: 6233323
    Abstract: The present invention utilizes common hardware and software routines already present in most digital telephone devices, e.g., a DTMF detector; to download data over a telephone line to a digital telephone device. Each symbol of a numeric system, e.g., a hexadecimal system, used to represent the data is associated with a DTMF tone pair. The DTMF tone pair is downloaded from a data source such as a manufacturer of the digital telephone device, to the digital telephone device using a telephone line. Other tones may be used to provide control signals between the data source and the digital telephone device. Thus, using common and inexpensive routines in a typical digital telephone device, the expense of a modem or other conventional data communication device is not necessary to receive data.
