  • Patent number: 10491732
    Abstract: A transmitter modulates an input voice signal to transmit an RF signal. A receiver demodulates a received RF signal to output an output voice signal. A voice level comparator compares a level of an input voice signal obtained by collecting a voice by a microphone with a VOX sensitivity level. A transmission determination unit instructs the transmitter to transmit the input voice signal, when the level of the input voice signal is equal to or greater than the VOX sensitivity level, based on a comparison result by the voice level comparator. A VOX sensitivity level calculator calculates the VOX sensitivity level in a predetermined period until just before the receiver completes outputting the output voice signal, based on an ambient sound collected by the microphone.

  • Patent number: 8639208
    Abstract: A mobile device and method in one example for automatically redialing a dialed number when a call has failed is provided. The mobile device stores the dialed number when the call is initially being placed. If the call fails, the mobile device determines if a call retry service should be invoked. If so, the mobile device determines whether a call retry system has already been enabled. If the call retry system has been enabled, the mobile device will continually and automatically call the dialed number until a terminating party at the dialed number answers or a selectable time limit has expired. When the terminating party answers the call, the mobile device rings so that a subscriber of the mobile device may answer the ring and connect the call. The mobile device may also detect if the dialed number is an emergency number or non-emergency number. A recorded message recorded by the subscriber may be automatically played to the terminating party if the subscriber does not answer the ring.

  • Patent number: 7068777
    Abstract: A circular dial buffer is implemented in appropriate random access memory (RAM) accessible by a DSP for the purpose of storing DTMF digits to be generated and output on, e.g., a telephone line. To the processor, the DSP appears to behave much like an off-the-shelf stand alone touch tone dialer, with the exception that the DSP does not have access to a keypad input. Instead, in addition to speed dial capabilities, mimicked keypad input is transmitted by a controller to the DSP rather than timing information. Thus, instead of requiring the input of rows and columns or other information relating to button activation on a connected keypad to input touch tone digits, the principles of the present invention allow mimicking of keypad input using commands sent by the controller to the DSP, e.g., a first command indicating that a mimicked, manually operated key is being pressed, and a second command indicating that the mimicked key has been released.

  • Patent number: 7020280
    Abstract: A method of processing a phone dialing process. At first, whether the dial key signal of the dial device is inputted is checked. When the dial key signals of the dial device are inputted and the dial device is not connected, that is, a user is pressing a phone number, the values corresponding to the inputted dial key signals are sequentially stored in a first memory. When the dial device is connected but the dial key signals of the dial device are still inputted, which means that the user is pressing an extension number or a key instruction, the values corresponding to the inputted dial key signal are also stored in the first memory. In addition, at least a time value is stored in a second memory. During the redial procedure, the time value can be used to properly process the time delay problem between the normal phone number and the extension number.

  • Patent number: 6961424
    Abstract: There is provided methods and devices for relaying tone events in a communication system. A first tone data indicative of a first tone is received and buffered. Following, a second tone data indicative of a second tone is received and buffered. The first and second tones can be, for example, DTMF digits. A processor retrieves the first tone data from the buffer and generates the first tone corresponding to the first tone data. The first tone is generated for at least a first predetermined period, which can be approximately 50 msec, for example. After the first tone has ended, the processor waits for a second predetermined period before retrieving the second tone data from the buffer. The second predetermined period can be, for example, 50 msec. Subsequently, the second tone corresponding to the second tone data is generated for at least the first predetermined period of time.

  • Publication number: 20030007630
    Abstract: A push-button signal receiving device and a gain control method whereby error in validity determination of a received signal that accompanies the insertion of an AGC circuit can be prevented. An input bush-button signal is amplified by amplifying circuit and separated into signals of low- and high-frequency bands by first and second band-pass filters, respectively. Dialed number identifying circuit detects the frequencies of the separated signals to identify the dialed number, determines validity of the received push-button signal, and outputs the identified dialed number in accordance with the result of validity determination. Level detecting circuit detects the level of the output signal from the amplifying circuit. Gain control circuit controls the amplification gain of the amplifying circuit in accordance with the detected signal level, and holds the value of the amplification gain of the amplifying circuit while the received push-button signal is judged valid by the dialed number identifying circuit.
