Abstract

The present invention relates to an RF communication system and method for control of user devices via wireless RF communication. In order to provide a flexible use and a number of different applications and, in particular, in order to avoid the need for training user devices beforehand and the need of knowledge of the actual meaning of communicated user settings and/or commands to the passive data carrier, an RF communication system is proposed comprising: a user device (6, 7, 11, 12, 13) for reading user settings and/or commands from a passive data carrier (3, 4, 5, 21, 22) via a wireless RF communication including a controller (64) for controlling the user device (6, 12) according to read user settings and/or commands and a programming unit (65) for automatically programming said passive data carrier (3, 4,5, 21, 15 22) via a wireless RF communication with actual user settings and/or commands of the user device (6, 7, 11, 12, 13), and a passive, via a wireless RF communication programmable and readable data carrier (3, 4, 5, 21, 22) including a memory (31) for storing user settings and/or commands.

Claims

1. RF communication system for control of user devices via a wireless RF communication comprising:

a user device for reading user settings and/or commands from a passive data carrier via a wireless RF communication including a controller for controlling the user device according to read user settings and/or commands and a programming unit for automatically programming said passive data carrier via a wireless RF communication with actual user settings and/or commands of the user device, and

a passive, via a wireless RF communication programmable and readable data carrier including a memory for storing user settings and/or commands.

2. RF communication system as claimed in claim 1, further comprising a programming device having an input means for inputting user settings and/or commands for explicitly programming said passive data carrier.

3. RF communication system as claimed in claim 1, wherein said passive data carrier further comprises:

a receiving means for receiving RF signals,

a processing means for processing said received RF signals to obtain said user settings and/or commands embedded therein and/or for embedding stored user settings and/or commands into output RF signals or RF signal modulations of said received RF signals, and

an output means for outputting said output RF signals or RF signal modulations.

4. RF communication system as claimed in claim 3, wherein said passive data carrier is a passive RFID tag.

5. RF communication system as claimed in claim 3, wherein said passive data carrier is integrated into a mobile user apparatus, in particular into a mobile phone, a transponder, a SmartCard or a PDA.

6. RF communication system as claimed in claim 3, wherein said user device further comprises:

an RF transmitter for emitting RF signals,

a detector for detecting RF signals or RF signal modulations of emitted RF signals,

a processor for processing the detected RF signals or RF signal modulations and for deriving user settings and/or commands embedded therein.

7. RF communication system as claimed in claim 1, wherein said passive data carrier is adapted for storing a number of different sets of user settings and/or commands for control of different types or selected user devices.

8. RF communication system as claimed in claim 6, wherein said user device further comprises an identification means for embedding identification information identifying said user device and/or the type of said user device into RF signals emitted by said RF transmitter.

9. RF communication system as claimed in claim 6, wherein said processing means of said passive data carrier further comprises:

an identifier means for processing said received RF signals to obtain identification information identifying said user device and/or the type of said user device and

a selecting means for selecting stored user settings and/or commands related to said type or said user device to be embedded into said output RF signals or said RF signal modulations of said received RF signals by said processing means.

10. RF communication system as claimed in claim 1, comprising a plurality of passive data carriers positioned at different locations for control of user devices present in respective control areas around said different locations according to stored user settings and/or commands.

11. RF communication system as claimed in claim 1, comprising a plurality of passive data carriers associated to different users for control of user devices according to stored user settings and/or commands.

13. User device for use in a RF communication system as claimed in claim 1 for reading user settings and/or commands from a passive data carrier via a wireless RF communication, comprising:

an RF transmitter for emitting RF signals,

a programming unit for automatically programming said passive data carrier via said RF signals with actual user settings and/or commands of the user device

a detector for detecting RF signals or RF signal modulations of the emitted RF signals from said data carrier,

a processor for processing the detected RF signals or RF signal modulations and for deriving user settings and/or commands embedded therein, and

a controller for controlling the user device according to read user settings and/or commands.

14. Passive, via a wireless RF communication programmable and readable data carrier for use in a RF communication system as claimed in claim 1 comprising:

a memory for storing user settings and/or commands,

a receiving means for receiving RF signals,

a processing means for processing said received RF signals to obtain user setting and/or commands embedded therein and/or for embedding stored user settings and/or commands into output RF signals or RF signal modulations of said received RF signals, and

an output means for outputting said output RF signals or RF signal modulations.

12. RF communication method for control of user devices via a wireless RF communication comprising the steps of:

automatically programming a passive data carrier via a wireless RF communication with actual user settings and/or commands of a user device, said passive data carrier including a memory for storing said user settings and/or commands,

reading user settings and/or commands from said passive data carrier via a wireless RF communication,

controlling the user device according to read user settings and/or commands.
