Abstract

The present invention relates to a wireless apparatus for transferring information between computers. The communication device uses a diskette that transmits and receives information by using radio frequency. The diskette includes receiving and transmitting circuitry which is used in conjunction with software to facilitate the file transfer.

Claims

1. A communications device for wireless transmission of data between computers or related devices, said communications device comprising;

an antenna;

a diskette housing configured for insertion into a diskette drive of a computer;

a read/write head integral to said diskette housing for receiving and transferring data from the diskette drive of the computer and converting said data into a first signal in an encoder/decoder;

a modulator operatively connected to the encoder/decoder connected to the read/write head for transforming said first digital signal into a first radio-frequency signal; and

a radio-frequency transmitter operatively coupled to said modulator for wireless transmission of said first radio-frequency signal via said antenna.

2. The communications device of claim 1 further comprising:

a radio-frequency receiver coupled to said antenna for receiving a second radio-frequency signal;

a demodulator operatively connected to said receiver for transforming said second radio-frequency signal into a second digital signal; and

said read/write head being further coupled to said encoder/decoder for converting said second digital signal into data for writing to said read/write head.

3. The communications device of claim 1 wherein said diskette housing includes, said read/write head, said modulator, said radio-frequency transmitter and said antenna.

4. The communications device of claim 3 wherein said diskette housing is identical in shape and size to a conventional 3.5" inch high-density floppy diskette.

5. The communications device of claim 2 further comprising a diskette housing containing said read/write head, said demodulator, said radio-frequency receiver and said antenna.

6. The communications device of claim 1 wherein said first radio-frequency signal is about 2.4 Gigahertz.

7. The communications device of claim 2 wherein said second radio-frequency signal is about 2.4 Gigahertz.

8. The communications device of claim 1 wherein said antenna is a dipole strip antenna.

9. The communications device of claim 3 wherein said diskette housing contains a disk of plastic material having an embedded plurality of magnets for rotation by a diskette drive mechanism;

a plurality of pick up coils that are fixed with respect to said plurality of magnets whereby an A-C voltage is induced in said pick up coils as said plastic disk is rotated;

a rectifier and converter operatively connected to said pick up coils for converting said AC voltage into a DC voltage sufficient to power said communications device.

10. A wireless communications system for wireless transmission of data between computers or related devices, said system comprising:

a diskette housing further comprising

a first communications device comprising

a first antenna;

a first read\write head for reading said data from a diskette drive of a computer and converting said data into a first digital signal;

a modulator connected to said first read\write head for transforming said first digital signal into a radio-frequency signal; and

a radio-frequency transmitter operatively coupled to said modulator for wireless transmission of said radio-frequency signal via said first antenna; and

a second communications device comprising a second diskette housing comprising

a second antenna;

a radio-frequency receiver coupled to said second antenna for receiving said radio-frequency signal;

a demodulator connected to said radio-frequency receiver for transforming said radio-frequency signal into a second digital signal; and

a second read/write head coupled to said demodulator for converting said second digital signal into data for transfer to a read/write head of a second computer;

said first communications device located in a first computer in which said data to be transferred is located;

said second communications device located in said second computer in which said data is to be transferred to.
