Dynamic Audio Signal Recording Or Reproduction Patents (Class 379/68)
  • Patent number: 4866754
    Abstract: An automatic telephone answering and recording device, wherein if an incoming call is received when an incoming message tape is full or an owner fails to set the telephone answering device to an automatic answering mode prior to leaving, the telephone line is nevertheless engaged to operate the telephone answering device. Then an outgoing message for answering only, such as "Please call back later", is generated by a voice synthesizer and sent out to a calling party, so that the calling party can understand the situation and know what to do.

  • Patent number: 4860338
    Abstract: A multiline telephone answering system includes a playback deck for supplying a prerecorded message and a plurality of interface units for interconnecting a plurality of telephone lines and the playback deck. Each interface unit is associated with a particular telephone line and supplies a start signal to the playback deck when its associated line is ringing. Each interface unit is responsive to the state of the playback deck for connecting its line to the playback deck only at the start of the prerecorded message and inhibits the connection between the playback deck and its telephone line unless that telephone line is ringing at the start of the prerecorded message.

  • Patent number: 4856050
    Abstract: A message retrieval system is disclosed which includes a plurality of answering machines, each connected to respected telephone line. Each answering machine records telephone responses on a respective message memory unit and all message memory units are connected to a single message processor. The message processor is in turn connected to a number of retrieval consoles used by operators to transcribe messages from the message memory units.

  • Patent number: 4834551
    Abstract: The system comprises an apparatus for signalling to a party on hold that the hold initiating party is ready to continue conversation. As soon as the hold initiating party places the other party on hold, the party on hold activates the system which causes a pre-recorded message to be transmitted back to the hold initiating party. The pre-recorded message invites the hold initiating party to produce a DTMF signal tone. The DTMF signal activates a tone detector which turns off the message generator and produces an audio and visual signal to alert the party on hold. In this manner the party on hold is free to pursue normal activities until such time as the hold initiating party is ready to talk.

  • Patent number: 4827461
    Abstract: Input coupling apparatus for coupling a telecommunications link, such as a telephone line, to an audio device, such as a recording channel of a telecommunications logger. Input terminals connect the coupling apparatus to the telecommunications link, such as to the tip and ring leads of a telephone line, for receiving audio signals. Voltage, current and remote sensing devices are coupled to the input terminals for detecting an active mode, such as an off-hook condition, during which audio signals are present. When connected to a telephone line, either an off-hook voltage condition or an off-hook current flow is sensed to produce an off-hook signal. When coupled to another communications link, such as a radio link, an external, simulated off-hook signal is detected. A selector is coupled to the voltage, current and remote sensing devices and selects one of those devices to supply the off-hook signal to the audio device, for example, to enable a logger to record audio signals.

  • Patent number: 4807275
    Abstract: An electronic dispatch board for use with a voice message recording-playback machine. The dispatch board lights certain lamps responsive to signals sent from the message recording-playback machine when a message has been placed in a certain voice mailbox. The dispatch board is comprised of a serial-to-parallel converter, a board address comparator, an address signal verifier, a lamp driver, and a plurality of lamps. The address signal verifier determines if a valid address signal has been received from the message recording machine. A number of dispatch boards may be simultaneously connected to the same message recording machine. The board address comparator in each dispatch board determines if the address signal from the message recording machine is meant for that particular dispatch board. If a valid address signal has been received, a certain lamp is set to an on, off or blink state.

  • Patent number: 4788713
    Abstract: At least two operation buttons are arranged to set one of a plurality of operation modes of a recording/reproducing apparatus. When each operation button operated a plurality of times within a predetermined period of time is detected by a microprocessor, a switching circuit sets a recording medium in a predetermined operation mode determined by the operation/non-operation and the number of operations of each operation button. In the predetermined operation mode, at least one recording medium mounted in the recording apparatus is erased while being rewound or fast forwarded.
