In one or more embodiments described herein, devices, systems, methods and/or apparatuses are described that can facilitate locational awareness and/or guidance of an inductive charging element relative to a target charging station. A device can comprise an inductive charging element, a signal component located relative to the inductive charging element for common movement with the inducting charging element, wherein the signal component transmits or receives a signal from a target position, and a controller that determines a distance between the inductive charging element and the target position based on a time measurement of the signal. The time measurement can include a time of arrival measurement and/or a time of flight measurement. The signal component can be an ultrawideband antenna, laser doppler device, acoustic device, electromagnetic device and/or other transmitter and/or receiver. |

Configurable plasma generating system
Power circuitry for non-thermal plasma generation; optionally therapeutic plasma. Non-thermal plasma is generated distally by a catheter-like device which is flexible, narrow (e.g., diameter<5 mm), and longitudinally extended to reach, e.g., 50-100 cm into body cavities. A plasma probe power transmission cable is a part of the power generating circuit, its intrinsic impedance contributing to and constraining the time constant of an entraining RC circuit whose resonant frequency entrains the frequency of power generation by feedback. Variable length, construction and/or manufacture (for example) of the plasma probe potentially lead to different time constants. In some embodiments, transformer coupling is divided into a plurality of stages, allowing the final-stage transformer inductance to be selected with sufficient headroom to allow the use of compensation componentry to mask probe variability and maintain a targeted operating frequency. Various configurations for selecting and/or providing compensation componentry are disclosed. |

Power supply system with current sharing and method of current sharing the same
A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load. |
