Abstract

Methods and systems for wirelessly transmitting power and/or data.

First claim

The invention claimed is:

1. An assembly comprising:
(a) a transmitter unit and a receiver unit, the transmitter unit capable of transmitting wireless electrical power to the receiver unit;
(b) the receiver unit having a first wired connector capable of selective and disengageable manual connection to a power consuming load device such that said power consuming device may receive said wireless electrical power when connected, and a second wired connector capable of selective and disengageable manual connection to a power storage device, where said first wired connector is capable of delivering electrical power to said power consuming device from said power storage device when said receiver unit does not receive said wireless electrical power from said transmitter unit.

2. The assembly of claim 1 where said transmitter unit is capable of wirelessly transmitting data to the receiver unit.

3. The assembly of claim 2 where said transmitter unit transmits at least one of RF data and network protocol data.

4. The assembly of claim 1 where said receiver unit is capable of wirelessly transmitting data to the transmitter unit.

5. The assembly of claim 4 where said transmitter unit transmits at least one of RF data and network protocol data.

6. An assembly comprising:
(a) a transmitter unit and a receiver unit, the transmitter unit capable of transmitting wireless electrical power to the receiver unit;
(b) the receiver unit having a first wired connector capable of selective and disengageable connection to a battery and a second wired connector capable of selective and disengageable connection to a power consuming load device; where
(c) said first wired connector is capable of recharging the battery using a first portion of said wireless electrical power while said second wired connector simultaneously delivers a second portion of said wireless electrical power to said power consuming load device.

7. The assembly of claim 6 where said first wired output is capable of receiving electrical power from said battery.

8. The assembly of claim 7 where said electrical power received from said battery is capable of powering said power consumption device when said power consumption device is connected to said receiver unit.

9. The assembly of claim 8 including a power management control device in said receiver unit that manages the use of said wireless electrical power and electrical power from said battery.

10. The assembly of claim 6 including an inductive coil in said receiver unit.

11. The assembly of claim 10 where said inductive coil is electrically connected to a power management module that selects whether to send electrical power to said power consumption device from said inductive coil, from said battery, or from said inductive coil and said battery.

12. An assembly comprising:
(a) a housing containing an inductive coil capable of receiving wireless electrical power; (b) an input connector for wired electrical power from a storage device external to the housing;
(c) an output connector capable of delivering electrical power to a load external to the housing; and
(d) circuitry implementing a power management system that selectively routes output power to said output connector, said output power comprising an automatically selected combination of said wired electrical power from said storage device and said wireless electrical power.

13. The assembly of claim 12 where said power management system is capable of selecting only said wireless electrical power to route to said output connector.

14. The assembly of claim 12 where said power management system is capable of selecting only said wired electrical power to route to said output connector.

15. The assembly of claim 12 where said wired electrical power is from a battery.

16. The assembly of claim 15 where said power management system may selectively recharge said battery using a first portion of said wireless electrical power while delivering a second portion of said wireless electrical power to said output terminal.
