Abstract

The P-Pad provides two main functions: (a) it allows users of mobile devices to recharge the batteries of the mobile devices when the devices are not in use by simply placing the mobile device anywhere on the P-Pad. (b) it allows automatic synchronization and updating of the mobile device with A/V or other data, for example with A/V content from the PVR anywhere in the home.

P-Pad: Data Synchronization and Charging Pad for

Devices

Description of the Invention:

The P-Pad provides two main functions:
(a) it allows users of mobile devices to recharge the batteries of the mobile devices when the devices are not in use by simply placing the mobile device anywhere on the P-Pad.
(b) it allows automatic synchronization and updating of the mobile device with A/V or other data, for example with A/V content from the PVR anywhere in the home.

Invention Disclosure:

This invention is based on the recognition of two basic facts:

(a) mobile devices, e.g. cell phones or wireless-capable devices such as the PSP, need to have their batteries charged with power periodically.  Presently the charging of mobile devices is tedious, involving cables and small connectors.  

Battery

charging must be made more user-friendly.

(b) much content (e.g. time-shifted content) does not need to be streamed in real-time (e.g. from the home media server to a wireless PSP or Airboard).  Such content can in fact be pre-stored on the mobile device just as the content is pre-stored on the PVR in the home, so the content can be played back locally on the mobile device as needed.  All that needs to be done is to easily synchronize the mobile device with relevant content from the PVR.
In this invention, (a) and (b) are solved using a Pad referred to as P-Pad (PSP-Pad?).  The P-Pad inductively charges a mobile device placed anywhere on the Pad.  Simultaneously, the data contents of the mobile device (e.g. A/V contents stored in Flash) is automatically selectively updated from the Home Media Server /PVR, using Near Field Communications between the P-Pad and the mobile device. The Home Media Server /PVR is connected to the P-Pad via the Powerline Communications Network (PLC) of the home.

There are two main features of the P-Pad:
(a) Inductive Battery charging
The P-Pad automatically charges the mobile device placed anywhere on the surface of the P-Pad.  The mobile device must also support inductive charging.  The principles of inductive charging are in themselves not new and can be found in rechargeable electric toothbrushes.  However such devices require exact placement of the toothbrush into a socket for charging, and in such cases inductive charging is used more for elec...
