Abstract
Devices and methods are presented to remotely dial wireless communications devices. A device is equipped with a microphone and a plurality of logic units to analyze incoming acoustic signals in the form of Morse code. Acoustic signals may comprise tapping sounds, or voice patterns to create the “dits” and “dahs” associated with Morse code. Background noise can be eliminated using digital signal processing (DSP). The device can be used in a variety of environments where phone numbers and addresses need to be dialed from a distance or in emergency situations.
Claims22
A wireless communications device comprising:
- a transceiver within the device;
- a keypad within the device;
- a microphone within the device;
- a first logic unit for analyzing a coded incoming signal corresponding to a destination address of a second device;
- and
- a second logic unit for automatically dialing the destination address and establishing a communication link between the device and the second device.
A wireless communications device comprising:
- a transceiver within the device;
- a keypad within the device;
- a microphone within the device;
- a first logic unit for analyzing a coded incoming signal corresponding to a destination address of a second device, wherein the coded incoming signal comprises a plurality of sounds in the form of Morse code;
- and
- a second logic unit for automatically dialing the destination address and establishing a communication link between the device and the second device.
A wireless communications device comprising:
- a transceiver;
- a keypad;
- a microphone for receiving digits of a phone number, wherein the digits are communicated through an acoustic signal corresponding to binary notation for each digit in the phone number;
- a means for analyzing the acoustic signal to receive the phone number;
- and
- a means for automatically dialing this phone number after it has been received by the phone.
A method for dialing a wireless communications device, the method comprising:
- receiving on a first device an input in the form of a code, wherein the code corresponds to a destination address of a second device;
- analyzing the input to determine the destination address;
- and
- establishing a communications link between the first and second devices.
A method for establishing a communication link between a first and a second device, the method comprising:
- collecting and storing data on the first device related to an incoming acoustic signal, wherein the data comprises a plurality of variations in the amplitude or duration of the incoming acoustic signal;
- and
- correlating the data to a destination address for the second device.
