Abstract

A Continuous Data Beaming System that is capable of continuously and automatically beaming data by direct transmission from one Host Device (source device or “beaming station”) to another Remote Device (receiver device) every time the receiver needs the data. The Host Device constantly searches to find an IrOBEX compliant Remote Device, checks availability for an infrared connection, completes the connection to the Remote Device and transfers a data object through the respective infrared ports. If a failure occurs during any of the foregoing steps, the program automatically returns to searching. This progresses in an infinite loop, thereby accomplishing continuous, wireless, infrared data transmission. During the continuous transmission, no Remote Device other than BeamMaster can interrupt the continuous beaming. The BeamMaster Device allows the system to halt for a brief period, thirty seconds or less, so that files or data objects may be swapped. Continuous beaming resumes once the files are swapped or the time has expired. The Host Device automatically transmits data to the receiver device every time a receiver shows up and needs the data, thereby effectively achieving one-touch wireless synchronization.

Claims

1. A method for continuous, wireless infrared data transmission, comprising the steps of:

searching with a Host Device using an infrared communication protocol to find a Remote Device having an IrOBEX compliant port;

checking for availability of an infrared connection if the Host Device finds a Remote Device having an IrOBEX compliant port;

establishing infrared communication between said Host Device and Remote Device when said infrared connection is available and transferring a file or data object through the respective IrOBEX compliant ports;

recording a successful transfer event in a log file if the file or data object is transferred successfully;

repeating the foregoing steps to effect continuous, wireless infrared data transmission.

2. The method according to claim 1, further comprising the step of checking for scheduled HotSync times and performing a Hot Sync to the server to dynamically update file contents if the time equals the schedule time and continuing beaming existing data object if the times does not equal the schedule time.

3. The method according to claim 1, wherein said step of searching from a Host Device to find an IrOBEX compliant Remote Device is repeated if the Host Device cannot find an IrOBEX compliant Remote Device.

4. The method according to claim 1, wherein said step of checking for availability of an infrared connection is repeated if the Remote Device is not available for connection.

5. The method according to claim 1, wherein said step of transferring a file or data object through the respective compliant ports is repeated if the file or data object is not successful.

6. The method according to claim 1, further comprising the step of checking for a BeamMaster target device, halting the continuous beaming for a short pre-defined period of time to enable the swapping of files or data objects if a BeamMaster target device is detected, swapping the files or data objects, and resuming the continuous beaming.

7. The method according to claim 6, wherein said continuous beaming continues uninterrupted if a BeamMaster target device is not detected.

8. A method for continuous, wireless data transmission, comprising the steps of:

searching from a Host Device to find a Bluetooth wireless technology compliant Remote Device, both of said devices having compliant ports;

checking for availability of a connection if the Host Device finds a Bluetooth compliant Remote Device;

making the connection between Host Device and Remote Device and transferring a file or data object through the respective compliant ports if the Remote Device is available for connection;

recording the transfer in a log file as a successful event if the file or data object is transferred successfully;

whereby continuous, wireless data transmission occurs.

9. An apparatus for performing continuous, wireless infrared data transmission, comprising:

a means for searching from a Host Device to find an IrOBEX compliant Remote Device, both of said devices having compliant ports;

a means for checking for availability of an infrared connection if the Host Device finds an IrOBEX compliant Remote Device;

a means for making the connection between Host Device and Remote Device and transferring a file or data object through the respective compliant ports if the Remote Device is available for connection;

a means for recording the transfer in a log file as a successful event if the file or data object is transferred successfully;

whereby continuous, wireless infrared data transmission occurs.

10. The apparatus according to claim 9, further comprising the means of checking for scheduled HotSync times and performing a Hot Sync to the server to dynamically update file contents if the time equals the schedule time and continuing beaming existing data object if the times does not equal the schedule time.

11. The apparatus according to claim 9, wherein said means of searching from a Host Device to find an IrOBEX compliant Remote Device is repeated if the Host Device cannot find an IrOBEX compliant Remote Device.

12. The apparatus according to claim 9, wherein said means of checking for availability of an infrared connection is repeated if the Remote Device is not available for connection.

13. The apparatus according to claim 9, wherein said means of transferring a file or data object through the respective compliant ports is repeated if the file or data object is not successful.

14. The apparatus according to claim 9, further comprising the means of checking for a BeamMaster target device, halting the continuous beaming for a short pre-defined period of time to enable the swapping of files or data objects if a BeamMaster target device is detected, swapping the files or data objects, and resuming the continuous beaming.

15. The apparatus according to claim 14, wherein said means of continuous beaming continues uninterrupted if a BeamMaster target device is not detected.
