Abstract

Improvements in a portable hand-held radio frequency wireless remote control are disclosed. The dockable wireless remote control satisfies the need for a low cost compact portable remote control and can advantageously perform additional functions not performed by previous portable wireless remote control units. It can be carried by the user and used like a conventional remote control. It also enables software control of remote devices when connected (docked) to a computer by way of a direct electrical I/O connection. The proposed remote control provides a means to expand the capabilities of portable compact radio frequency wireless remote controls when needed for advanced control functions without significantly compromising their small size or low cost.

Claims

1. A portable remote control unit, comprising:

a radio frequency transmitter and receiver for wireless communication between the remote control unit and the controlled device or system;

an energy storage device which provides power to the remote control unit when power is not externally supplied;

one or more buttons which are operated by the user for activating remote control functions in the controlled device or system;

an electrical I/O communication interface which can be connected to a host computer'"'"'s I/O port,

wherein said portable remote control unit is capable of operating as a wireless control interface to remote devices or systems using said buttons operated by the user, and is capable of operating as a wireless control interface to remote devices or systems under host software control when connected to said host computer'"'"'s I/O port, and

wherein said portable remote control unit is capable of controlling by means of said buttons at least one of the operational functions provided by the controlled device or system for its intended application and use.

2. The portable remote control unit of claim 1, wherein said remote control'"'"'s electrical I/O communication interface comprises a universal serial bus USB connector and USB interface electronics.

3. The portable remote control unit of claim 1, wherein said remote control'"'"'s transmitter and receiver is utilized by computer software for control of remote devices or systems when said remote control is docked to a computer.

4. The portable remote control unit of claim 1, wherein said remote control is used for control of certain operational features in the controlled device or system by means of said buttons when undocked from a computer and for control of additional features in the controlled device or system by means of computer software when said remote control is docked to a computer.

5. The portable remote control unit of claim 1, wherein said remote control receives its power from a computer instead of from said energy storage device when said remote control is docked to a computer.

6. The portable remote control unit of claim 1, wherein said remote control further comprises one or more indicators for display of status received from the controlled device or system.

7. The portable remote control unit of claim 2, wherein said energy storage device is a rechargeable battery which provides power to said remote control unit when it is undocked, and is recharged by means of said USB connector when it is docked to a computer.

8. The portable remote control unit of claim 1, wherein said remote control is used to control the operation of remote devices or systems as a replacement for a separate, dedicated wireless control unit attached to a computer.

9. The portable remote control unit of claim 1, wherein said remote control unit has the capability to be linked with the controlled device or system in order to restrict access from remote control units which have not been so linked.

10. The portable remote control unit of claim 1, wherein said remote control, when docked to a computer, has the capability to be configured by the computer to redefine said button functions and to redefine control functions when undocked.

11. The portable remote control unit of claim 1, wherein said remote control, when docked to a computer, has the capability to be configured to limit specific control operations to a predetermined number of uses when it is undocked.

12. The portable remote control unit of claim 1, wherein said remote control, when docked to a computer, has the capability to be configured to transmit a predetermined personal security code to the controlled device or system when it is undocked.

13. The portable remote control unit of claim 1, wherein said remote control has the capability to cause the controlled device or system to transmit data back to said remote control, which receives the information and stores it for conveyance to computer software when it is docked to a computer.

14. The portable remote control unit of claim 13, wherein said remote control has the capability to wirelessly extract data from a controlled device or system when it is undocked and store it for transport it to a distant computer which is out of wireless transmission range of the controlled device or system.

15. The portable remote control unit of claim 2, wherein said remote control further comprises flash memory for storing data which can be written and read by means of said USB connector.

16. The portable remote control unit of claim 15, wherein said remote control functions as a removable data storage drive when said flash memory is accessed by a host computer using said USB connector.

17. The portable remote control unit of claim 2, wherein a removable cover slides over said USB connector and acts as a protective cap.

18. The portable remote control unit of claim 17, wherein said cover has the capability to be used as a handle while the user operates the remote control buttons.

19. The portable remote control unit of claim 1, wherein said remote control is capable of enabling full operational power to its wireless receiver for only a time adequate to receive a response from the controlled device or system after it transmits a control signal to the controlled device or system.

20. The portable remote control unit of claim 19, wherein said remote control extends the available energy life from said energy storage device by enabling its receiver only when needed to receive expected transmissions from the controlled device or system.
