Abstract: Multi-cell battery packs can be made safer with certain features that mitigate the consequences of cell failure. Parameters of a cell are monitored to determine when the cell should be disconnected from the pack in case of a fault. The battery is reconfigured to continue operating in a safer mode. An over-charging prevention system reduces the maximum voltage that remaining battery pack can be charged to, so that the cells do not overcharge. Additional circuitry allows the disconnected cell to be periodically reconnected to the battery pack to determine if its conditions have sufficiently improved. The cells also include components for self-powering these cell functions while it is disconnected from the rest of the circuit.

Abstract: There is provided in accordance with an exemplary embodiment of the invention a method of osteointegration of an implant into surrounding jaw-bone, the method comprising: applying a magnetic field around an implant, the magnetic field produced around the implant to a jaw-bone depth of up to at least about 7 mm, the magnetic field having a magnetic flux density of about 0.05-0.5 mT at up to at least about 2 mm from a surface of the implant, the magnetic field produced by a coil within the implant. A device adapted for insertion into a jawbone implant and for producing the magnetic field for bone enhancement of surrounding jawbone is also described.
