Abstract

A method and an apparatus for enabling battery power saving in an associated device is disclosed. Said battery saving is enabled by receiving electromagnetic energy carried by a wireless signal, obtaining operating power from the received electromagnetic energy, receiving a data unit over a wireless link, storing the data unit in a memory, and providing the data unit from the memory in response to a memory read request received via an input/output controller.

Claims

1. A method comprising:

receiving via a first wireless link electromagnetic energy carried by a wireless signal;

obtaining operating power from the received electromagnetic energy;

receiving a data unit over a second wireless link that is separate from the first wireless link, wherein the second wireless link is an impulse radio link;

storing the data unit in a memory; and

providing the data unit from the memory in response to a memory read request received via an input/output controller.

2. A method according to claim 1, further comprising:

receiving a second data unit via the input/output controller;

storing the second data unit in the memory; and

providing the second data unit from the memory in response to a second memory read request received via the second wireless link.

3. A method according to claim 1, further comprising:

receiving program commands via the second wireless link; and

providing the program commands via the input/output controller.

6. A method according to claim 3, further comprising:

receiving parameters associated with the program commands via the second wireless link; and

providing the parameters via the input/output controller.

7. A method according to claim 3, wherein the program commands are provided to cause an application to launch and wherein the method further comprises:

receiving application data to be processed by the application via the second wireless link; and

providing the application data via the input/output controller.

4. (canceled)

5. (canceled)

8. An apparatus comprising:

a power unit configured to receive via a first wireless link electromagnetic energy carried by a wireless signal and to obtain operating power for the apparatus from the received electromagnetic energy;

a communication unit configured to operate a communication connection over a second wireless link that is separate from the first wireless link, wherein the second wireless link is an impulse radio link;

an input/output controller;

a memory; and

a processor configured to;

receive a data unit from a peer apparatus via the second wireless link;

store the data unit in the memory; and

to

provide the data unit from memory through the input/output controller in response to a memory read request received through the input/output controller.

9. An apparatus according to claim 8, wherein the processor is further configured to:

receive a second data unit through the input/output controller;

store the second data unit in the memory; and

to

provide the second data unit from the memory through the communication unit in response to a second memory read request received through the communication unit.

10. An apparatus according to claim 8, wherein the data units carry application data.

14. An apparatus according to claim 8, wherein the first wireless link is an ultra high frequency or a near field communication link and the second wireless link is a ultra wideband link.

15. An apparatus according to claim 8, wherein the processor is further configured to:

receive program commands through the communication unit; and

to provide the program commands through the input/output controller.

16. An apparatus according to claim 15, wherein the processor is further configured to:

receive parameters associated with the program commands through the communication unit; and

to

provide the parameters through the input/output controller.

17. An apparatus according to claim 15, wherein the processor is further configured to:

launch an application responsive to the received program commands;

receive application data to be processed by the application through the communication unit; and

to provide the application data through the input/output controller.

18. An apparatus according to claim 8, wherein the apparatus is further configured to indicate to the peer apparatus one or more content selection criteria for content to be received via the second wireless link.
