Abstract

A transceiver device and method thereof for sending signals to and receiving signals from another device via a wireless connection and for providing information about the wireless connection to a user. An antenna coupled to the transceiver is visible to the user. The antenna is a lighted antenna that is adapted to provide a visual indication of a wireless signal to a user. The lighted antenna can be used to show that the transceiver is transmitting or receiving signals, that a data connection has been made, or that a Bluetooth piconet has been detected. The color and/or intensity of the lighted antenna can be varied to indicate, for example, the strength of the signal. With a lighted antenna, additional features and functionality can be incorporated into a transceiver device while maintaining the form factor of existing designs. The multi-functionality of a lighted antenna is particularly suited for smaller devices where space is at a premium.

Claims

1. A device for sending and receiving signals to and from another device via a wireless connection and for providing information about said wireless connection to a user, said device comprising:

a housing;

a transceiver disposed within said housing, said transceiver adapted to send and receive wireless signals;

an antenna having a base end and a distal end, said antenna coupled to said transceiver at said base end and extending from said housing, wherein at least a portion of said antenna is encased in light-transmitting material visible externally of said device; and

a light source coupled to said light-transmitting material by a light-conducting material, wherein light from said light source is conducted to said light-transmitting material and made externally visible along said portion of said antenna encased in said light-transmitting material, wherein said light from said light source provides a visual indication of a wireless signal and wherein said visual indication is varied according to a characteristic of said wireless signal.

2. The device of claim 1 wherein said visual indication is varied according to wireless signal strength.

3. The device of claim 1 wherein said visual indication is varied according to a type of wireless signal.

4. The device of claim 3 comprising:

a processor coupled to said transceiver, said processor adapted to vary said visual indication.

5. The device of claim 4 comprising:

a memory unit coupled to said processor, said memory unit for storing instructions executed by said processor for varying said visual indication.

6. The device of claim 1 wherein said visual indication is varied in color.

7. The device of claim 1 wherein said visual indication is varied in intensity.

8. The device of claim 1 wherein said transceiver is a Bluetooth-enabled device.

9. In a device comprising a transceiver and an antenna, a method for providing information about a wireless connection to a user, said method comprising the steps of:

a) sending and receiving signals to and from another device via said wireless connection;

b) providing a visual indication of a wireless signal, wherein said visual indication is displayed using said antenna, said antenna coupled to said transceiver and extending from said device, wherein at least a portion of said antenna is encased in light-transmitting material visible externally of said device, said light-transmitting material coupled to a light source by a light-conducting material, wherein light from said light source is conducted to said light-transmitting material, wherein light from said light source is made externally visible along said portion of said antenna encased in said light-transmitting material, wherein said light from said light source provides a visual indication of a wireless signal and wherein said visual indication is varied according to a characteristic of said wireless signal; and

c) varying said visual indication according to a characteristic of said wireless signal.

10. The method as recited in claim 9 wherein said step c) comprises the step of:

varying said visual indication according to wireless signal strength.

11. The method as recited in claim 9 wherein said step c) comprises the step of:

varying said visual indication according to a type of wireless signal.

12. The method as recited in claim 9 wherein said step c) comprises the step of:

varying said visual indication in color.

13. The method as recited in claim 9 wherein said step c) comprises the step of:

varying said visual indication in intensity.

14. The method as recited in claim 9 wherein said transceiver is a Bluetooth-enabled device.

15. A portable computer system comprising:

a housing;

a transceiver disposed within said housing, said transceiver adapted to send and receive wireless signals;

an antenna having a base end and a distal end, said antenna coupled to said transceiver at said base end and extending from said housing, wherein at least a portion of said antenna is encased in light-transmitting material visible externally of said device;

a light source coupled to said light-transmitting material by a light-conducting material, wherein light from said light source is conducted to said light-transmitting material and made externally visible along said portion of said antenna encased in said light-transmitting material, wherein said light from said light source provides a visual indication of a wireless signal and wherein said visual indication is varied according to a characteristic of said wireless signal; and

a processor coupled to said transceiver, said processor adapted to vary said visual indication.

16. The portable computer system of claim 15 wherein said visual indication is varied according to wireless signal strength.

17. The portable computer system of claim 15 comprising:

a memory unit coupled to said processor, said memory unit for storing instructions executed by said processor for varying said visual indication.

18. The portable computer system of claim 15 wherein said visual indication is varied according to a type of wireless signal.

19. The portable computer system of claim 15 wherein said visual indication is varied in color.

20. The portable computer system of claim 15 wherein said visual indication is varied in intensity.
