Abstract

An apparatus for wirelessly receiving power comprises a battery at least partially covered by magnetic material and a radio frequency (RF) charge energy receiving antenna surrounding the magnetic material and electrically coupled to the battery through a circuit card assembly (CCA).

First claim

What is claimed is:

1. An apparatus for wirelessly receiving power, comprising:
a battery at least partially covered by magnetic material;
a radio frequency (RF) charge energy receiving antenna surrounding the magnetic material and electrically coupled to the battery through a circuit card assembly (CCA), wherein the RF charge energy receiving antenna is a cylindrical coil surrounding the battery and the magnetic material; and
a radio frequency identification (RFID) antenna and RFID circuitry coupled to the CCA, the RFID antenna and RFID circuitry configured to identify a presence of the apparatus to a charging device, wherein the RF charge energy receiving antenna, the battery at least partially covered by the magnetic material, the CCA, the RFID antenna, and the RFID circuitry are integrated into a single module configured to be included in a personal communications hub.

2. The apparatus of claim 1 , wherein the CCA further comprises a charging circuit configured to provide battery charge state and battery temperature information to determine an amount of charging energy provided to the battery.

3. The apparatus of claim 2 , wherein the RF charge energy receiving antenna is responsive to RF energy at a first frequency and the RFID antenna is responsive to RF energy at a second frequency.

4. The apparatus of claim 3 , wherein the RF charge energy receiving antenna is responsive to RF energy at a frequency of approximately 6.78 MHz and the RFID antenna is responsive to RF energy at a frequency of approximately 13.56 MHz.

5. The apparatus of any of claims 1 , 2 , 3 , and 4 , wherein the magnetic material completely covers the battery.

6. The apparatus of any of claims 1 , 2 , 3 , and 4 , further comprising metal material located between the battery and the magnetic material.

7. The apparatus of any of claims 1 , 2 , 3 , and 4 , further comprising metal material located between the battery and the magnetic material, wherein the metal material and the magnetic material completely cover the battery.

8. An apparatus for wirelessly receiving power, comprising:
a battery;
a radio frequency (RF) charge energy receiving antenna surrounding and electrically coupled to the battery through a circuit card assembly (CCA), the RF charge energy receiving antenna being a cylindrical coil surrounding the battery;
magnetic material at least partially covering the battery, wherein the RF charge energy receiving antenna surrounds the magnetic material and the battery; and
a radio frequency identification (RFID) antenna and RFID circuitry coupled to the CCA, the RFID antenna and RFID circuitry configured to identify a presence of the apparatus to a charging device, wherein the RF charge energy receiving antenna, the battery, the CCA, the RFID antenna, and the RFID circuitry are integrated into a single module configured to be included in a personal communications hub.

9. The apparatus of claim 8 , wherein the CCA further comprises a charging circuit configured to provide battery charge state and battery temperature information to determine an amount of charging energy provided to the battery.

10. The apparatus of claim 9 , wherein the RF charge energy receiving antenna is responsive to RF energy at a first frequency and the RFID antenna is responsive to RF energy at a second frequency.

11. The apparatus of claim 10 , wherein the RF charge energy receiving antenna is responsive to RF energy at a frequency of approximately 6.78 MHz and the RFID antenna is responsive to RF energy at a frequency of approximately 13.56 MHz.

12. The apparatus of any of claims 8 , 9 , 10 , and 11 , wherein the magnetic material completely covers the battery.

13. The apparatus of any of claims 8 , 9 , 10 , and 11 , further comprising metal material located between the battery and the magnetic material.

14. The apparatus of claim 13 , wherein the metal material and the magnetic material completely cover the battery.
