Abstract: A method for monitoring the line impedance of a protective earth (“PE”) conductor is provided. The method injects a small stimulus current at a frequency much higher than the grid frequency. The stimulus current circulates in the loops between a grid-connected device and a grid source, creating small voltage drops in the grid conductors, resulting in a common mode voltage which can be measured. The method then includes measuring the common mode voltage and the residual current at a point of common coupling (“PCC”). The method then includes monitoring the resistive and reactive parts of the line impedance. For example, the method can monitor the line impedance and report a broken PE conductor or a high PE resistance, beyond a given threshold where safety becomes a concern.

Abstract: A method for variable electrostimulative behavior modification includes sensing placement of a first anatomical portion of a body in contact to a surface of a target object adapted. for behavior modification with a multiplicity of electrostimulative end points coupled to an energy source. The method additionally includes delivering an electrical neurostimulus through one of the end points nearest to the placement of the first anatomical portion in proximity to the surface the electrical neurostimulus including a waveform promoting a modification of behavior associated with the placement of the first anatomical portion in proximity to the surface. Thereafter, an anomalous characteristic of the sensed placement indicating a failure to modify the behavior may be detected and a profile of the waveform of the electrical neurostimulus changes to a different waveform in response to the anomalous characteristic of the sensed placement.
