Abstract: A control console (50) for supplying a drive signal to the power generating unit (324) of a surgical tool (310) includes a transformer (250c) with a primary winding (252) across which an AC voltage is applied, and a secondary winding (264) across which a drive signal is induced so the drive signal can be applied to the power generating unit (324) of the surgical tool (310), and a matched current source including a leakage control winding (246a, 246b, 246c) across which the AC voltage that is present across the primary winding induces a voltage and a capacitor (248) connected between the leakage control winding and the secondary winding (264). The matched current source is designed to produce a current that at least partially cancels a leakage current present in the drive signal applied to the surgical tool as a result of parasitic capacitance. The leakage control winding is internal to the transformer and includes a plurality of sub-windings (246a, 246b, 246c). The control console comprises a switch array (294) that selectively connects one or a plurality of the sub-windings between the capacitor (248) and ground to form the leakage control winding so that by setting said switch array, for a given voltage across the primary winding (252), the voltage that develops across the leakage control winding is selectively set.

Abstract: A signal separation system is provided which includes a plurality of serially-coupled signal transfer stages (102, 104, 106). A video information signal is applied to an input stage (102) and is delayed by at least the time interval of one horizontal television line (1-H) as it passes through the stages. Various ones of the stages which are 1-H apart in time include outputs, which are combined by weighting function (120-126) and summing or difference circuits (130-136) to produce bandwidth-limited transversal filter output signals. These signals are additively and subtractively combined (140, 150, 160, 156) to produce a combed band passed chrominance signal and a fully restored and combed luminance signal, thereby obviating the need for subsequent filtering before the signals are further processed. The bandwidth-limited signals may also be combined (162) to provide a user adjustable peaking control signal for the luminance information channel.
