Abstract

A system for compressing program files at a remote host computer and transmitting the compressed program files to one or more wireless interface devices using a wireless link. The received compressed files are stored in an electronically programmable storage device on the wireless interface device. The remote host includes a CPU, a storage device for running and storing one or more programs and a wireless link for communicating with the wireless interface device. The wireless interface device is able to control and access the one or more programs on the remote host using the wireless link.

Claims

1. A computer system comprising:

a remote host having a CPU and a storage device for running and storing one or more programs; and

one or more wireless interface devices, each wireless interface device including an electronically programmable memory storage device for storing compressed program files transmitted to said one or more wireless interface devices and means for communicating with a remote host by way of a wireless link for controlling and accessing said one or more propgrams on said remote host,

said remote host including means for communicating with said one or more wireless interface devices by way of said wireless link and means for compressing predetermined program files and trqansmitting said compressed program files to said one or more wireless interface devices by way of said wireless link.

2. The system as recited in claim 1, wherein said program files include a header portion and a code or data portion.

3. The system as recited in claim 2, wherein said compressing means includes means for forming a customized header.

4. The system as recited in claim 3, wherein said customized header includes a compressed portion and an uncompressed portion.

5. The system as recited in claim 4, wherein said uncompressed portion of said customized header includes a signature field which includes the type of the program file being compressed.

6. The system as recited in claim 4, wherein said uncompressed portion includes data representative of the version of compression software.

7. The system as recited in claim 1, wherein said program file is an executable file.

8. The system as recited in claim 7, wherein said executable file is an .EXE file.

9. The system as recited in claim 7, wherein said executable file is a .COM file.

10. The system as recited in claim 1, wherein said electronically programmable first memory storage devices are electronically erasable programmable read only memory storage devices.

11. The system as recited in claim 1, wherein said electronically programmable first memory storage devices are flash read only memory storage devices.

12. A wireless interface device for communicating with a remote host by way of a radio link, the wireless interface device comprising:

one or more electronically programmable first memory storage devices;

means for receiving compressed program files by way of a radio link and for storing said compressed program files in said one or more electronically programmable memory storage devices;

one or more electronically programmable second memory storage devices; and

means for decompressing said compressed program files and writing said decompressed program files to said one or more electronically programmable second memory storage devices.

13. The wireless interface device as recited in claim 12, wherein said program file is an executable file.

14. The wireless interface device as recited in claim 13, wherein said executable file is an .EXE file.

15. The wireless interface device as recited in claim 13, wherein said executable file is a .COM file.

16. The wireless interface device as recited in claim 12, wherein said electronically programmable first memory storage devices are electronically erasable programmable read only memory storage devices.

17. The system as recited in claim 12, wherein said electronically programmable first memory storage devices are flash read only memory storage devices.
