Abstract: Control consoles and methods for supplying a drive signal to a surgical tool are provided. The control console comprises a transformer with primary and secondary windings. The primary winding receives an input signal from a power source and induces the drive signal in the secondary winding to supply the drive signal to the surgical tool. A first current source comprising a leakage control winding is coupled to a path of the drive signal. The primary winding induces a first cancellation current in the leakage control winding to inject into the path of the drive signal to cancel leakage current. A sensor coupled to the path of the drive signal outputs a sensed signal to provide feedback related to leakage current. The sensor may connect to a second leakage current cancellation source and/or a fault detection stage. The power source may be variable and may also energize the second current source.

Abstract: A cartridge for an e-vaping device includes a conductive element extending through an interior of a dispensing interface to which a heating element is coupled. The conductive element may have a greater temperature coefficient of electrical resistivity than the heating element. The dispensing interface may include a fibrous wicking material, and the conductive element may be woven through an interior of the fibrous wicking material. A temperature of the dispensing interface may be determined based on monitoring an electrical resistance of the conductive element. An amount of pre-vapor formulation may be determined based on an electrical resistance of the bridge electrical circuit to an electrical signal between the heating element and the conductive element through the dispensing interface.

Abstract: A system and method communicate signals between a portable unit and a communications system. The portable device communicates with a base unit using inductive coupling. The base unit is further connected to a wider communication system such as a telephone network. Multiple, orthogonally arranged transducers are used in the base unit to provide a more complete magnetic field and to prevent mutual inductance nulls which are otherwise present in a magnetic field. The use of short-range inductive coupling minimizes the power requirements and limits interference with other sources. The inductive coupling may also be used to recharge a battery in the portable device.
