Apparatus and method for maintaining a defibrillator battery charge and optionally communicating
First Claim
1. A defibrillator assembly comprising:
- a defibrillator housing;
a rechargeable power source carried in the housing that selectively sources power used for a defibrillation shock, wherein the rechargeable power source is coupled to a recharging interface circuit carried in the housing, and wherein the recharging interface circuit wirelessly receives energy to charge the rechargeable power source;
a docking station;
an external charging circuit located outside of the housing and within the docking station, wherein the external charging circuit wirelessly transfers energy to the power source via a wireless coupling from the external charging circuit to the recharging interface circuit without conductive electrical contact between the docking station and the recharging interface circuit, and wherein the docking station supports the housing while the external charging circuit wirelessly transfers energy to the power source; and
communication means to transmit and receive defibrillator information between the housing and the docking station.

Abstract
Defibrillator assemblies and methods to wirelessly transfer energy from an external source to a battery or other rechargeable power source within the defibrillator assembly. The transfer of energy may be through a non-contact interface on a defibrillator cradle or a docking station that mounts the defibrillator. The rate of energy transfer may be equal to the energy drain caused by self-discharge and automated self-testing. Accordingly, since the rate of energy transfer is lower than that required to run the defibrillator system continuously, several wireless methods of energy transfer may be used. In addition, the defibrillator assembly may communicate diagnostic and non-diagnostic data to the external source.
