Abstract

An apparatus for communicating with a handheld device (e.g., a cellular telephone) is provided herein. A protective shroud is configured to enclose the handheld device and protect it against incidents that commonly cause damage to handheld devices. Integral to the protective shroud is at least one of an input component configured to receive user input and a wireless transceiver configured to transmit signals to and/or receive signals from the handheld device. In one example, where both the input component and the wireless transceiver are integral to the protective shroud, signals related to received user input (e.g., where the shroud serves as a keypad) may be transmitted to the handheld device even if the protective shroud is removed from the handheld device.

Claims

1. An apparatus for receiving user input, comprising:

a selectively removable protective shroud configured to enclose at least a portion of a handheld device when not removed from the handheld device; and

an input component integral with the protective shroud and configured to receive user input, the input component configured to generate a signal based upon the received user input such that the signal is transmitted to a second device when not transmitted to the handheld device.

2. The apparatus of claim 1, comprising a wireless transceiver integral with the protective shroud and configured to transmit the generated signal from the input component to at least one of the handheld device or the second device.

3. The apparatus of claim 1, the generated signal transmitted to the handheld device through an electrically operable contact point operably coupling the handheld device to the input component.

4. The apparatus of claim 1, the second device not comprising a handheld device.

5. The apparatus of claim 1, the input component comprising an alphanumeric keypad.

6. The apparatus of claim 1, the input component comprising at least one touch sensor.

7. The apparatus of claim 1, the input component comprising one or more user programmable portions.

8. The apparatus of claim 1, comprising a computer processing unit (CPU) integral with the protective shroud.

9. The apparatus of claim 8, comprising an electrically operable contact point operably coupling the CPU to the handheld device, power transmitted to the CPU from a power source integral with the handheld device through the contact point.

10. The apparatus of claim 1, comprising a power source integral with the protective shroud, the power source configured to supply power to the handheld device through an electrically operable contact point operably coupling the power source to the handheld device.

11. The apparatus of claim 1, comprising a sound transceiver integral with the protective shroud and configured to emit sound.

12. The apparatus of claim 1, comprising a sound transceiver integral with the protective shroud and configured to detect sound.

13. The apparatus of claim 2, the wireless transceiver configured to facilitate selective wireless communication through IEEE Standard 802.15.1.

14. The apparatus of claim 1, comprising a storage device integral with the protective shroud and configured to store data.

15. The apparatus of claim 1, the protective shroud comprising a storage device and the apparatus comprising a power source configured to supply power to the protective shroud.

16. The apparatus of claim 15, comprising a wireless transceiver integral with the protective shroud and configured to facilitate a transfer of data between the storage device comprised in the protective shroud and the handheld device.

17. The apparatus of claim 1, the protective shroud comprising at least one of:

a wireless transceiver;

a computer processing unit (CPU);

a power source;

a sound transceiver configured to at least one of emit or detect sound;

or

a storage device.

18. The apparatus of claim 17, the power source configured to provide power to the input component integral with the protective shroud.

19. The apparatus of claim 17, the power source configured to provide power to the input component integral with the protective shroud and to the handheld device.

20. The apparatus of claim 1, the protective shroud comprising at least two of:

a wireless transceiver;

a computer processing unit (CPU);

a power source;

a sound transceiver configured to at least one of emit or detect sound;

or

a storage device.
