| 20120242171 | SYSTEM AND METHOD FOR MONITORING OPERATION OF SWITCH ELEMENTS - Systems and methods are provided for monitoring operation of a circuit having a DC power supply, a load, and a switch element connecting the DC power supply to the load. The system includes a capacitive element coupling a first input node of a sensor element to a first interconnection node of the circuit between a first voltage supply terminal of the DC power supply and the load. The system also includes a grounding structure coupling a second input node of the sensor element to a ground plane isolated from the DC power supply. In the system, the grounding structure is positioned with respect to a second interconnection node of the circuit, between a second voltage supply terminal of the DC power supply and the load, so as to define a stray capacitance for carrying a transient signal resulting from the opening or closing of the switch element, which can be detected through the sensor element for monitoring the current switch state of the switch element. | 09-27-2012 |

| 20140167529 | TAP CHANGER WITH AN IMPROVED MONITORING SYSTEM - An on-load tap changer is provided having a plurality of modules, each of which is operable to change taps in a transformer winding. The tap changer includes a motor connected to rotate at least one shaft. The at least one shaft is connected to the tap change modules and is operable upon rotation to cause the tap change modules to each perform a sequence of operations that effectuate a tap change. A multi-turn absolute encoder is connected to the at least one shaft. A monitoring system is connected to the encoder and is operable to determine from the position of the at least one shaft where the tap change modules are in the sequence of operations. | 06-19-2014 |

| 20090315410 | Ultra-low current push-button switch interface circuit - Circuits and methods to achieve a switch interface circuit for a single pole, single throw (SPST) momentary push-button switch consuming a few tens of nanoamps whilst the push-button switch is closed, having low impedance input path when the switch is open in order to eliminate RFI interference have been achieved. The two states of the push-button switch, open and closed, maintain a low impedance path to one of the power supplies. The supply current is minimized whilst the switch is closed. The edge triggered detection of the switch event allows an extended switch-closed operation. | 12-24-2009 |
| 20120091824 | Electric Vehicle Supply Equipment with Line Fitting Disconnect Sensing - A system includes an electric vehicle supply circuit adapted to supply electric power to an electric vehicle, a line fitting arranged to connect the electric vehicle supply circuit to a source of electric power, and a sensor arranged to detect when the line fitting is being disconnected from the source of electric power. The electric vehicle supply circuit is adapted to interrupt the supply of electric power to the electric vehicle in response to the sensor to interrupt the flow of power through the electric vehicle supply circuit before the line fitting is disconnected from the power source. | 04-19-2012 |
| 20150145349 | SWITCHGEAR ASSEMBLY - A load or a generator is connected to an energy line, e.g. a ring feeder of an energy distribution network by using a switching system. For this purpose, the switching system has a thyristor circuit, which is connected in parallel to a disconnect switch and connects the transformer of the switching system to an energy line. Thereby an efficient disconnect switch can be realized, which can be dimensioned depending on the power of the load or generator. | 05-28-2015 |

| 20150348721 | REMOTE SWITCH CONTACT QUALITY MAINTENANCE - A system for maintaining integrity of a switch contact includes a first resistor-capacitor circuit, a second resistor-capacitor circuit, and a control switch. The first resistor-capacitor circuit is connected to an output of the switch contact and includes a first resistor and a first capacitor. Upon closing of the switch contact, a first wetting current flows through the switch contact. The second resistor-capacitor circuit includes a second resistor and a second capacitor. The control switch is connected between the output of the switch contact and the second resistor-capacitor circuit and is selectively closable to generate a second wetting current through the switch contact. The control switch may be operated as needed to maintain the integrity of the mechanical switch contact. | 12-03-2015 |

| 20090072630 | SEMICONDUCTOR DEVICE AND METHOD OF CONTROLLING ELECTROSTATIC ACTUATOR - A semiconductor device controls an electrostatic actuator having first and second electrodes. A voltage generation unit generates different types of voltages applied to the first and second electrodes. A control unit controls voltages generated by the voltage generation unit to be applied to the first and second electrodes. A capacitance detection unit detects a voltage of the first or second electrode to detect a capacitance between the first and second electrodes. The control unit applies a first voltage between the first and second electrodes and then a second voltage smaller than the first voltage between the first and second electrodes. Thereafter, the control unit switches one of the first electrode or the second electrode to a high impedance state and then changes a voltage applied to the other. The capacitance detection unit detects the amount of change in voltage of the first or second electrode to detect a capacitance between the first and second electrodes. | 03-19-2009 |
