Abstract: An endoscopic system can include an endoscope shaft having a proximal end and a distal end, and an electrically active sensor system including at least one sensor mounted proximate the distal end and positioned to sense at least one characteristic of an environment in which the distal end is located. The capacitance of the sensor system relative to earth ground maintains current leakage to a level that meets a cardiac float rating.

Abstract: An endoscopic system can include an endoscope shaft having a proximal end and a distal end. The endoscopic system can have a sensor system that includes an electrically active sensor mounted proximate the distal end and positioned to sense at least one characteristic of an environment in which the distal end is located, a data signal transmission line connected to the sensor to transmit data signals between the sensor and a signal processor, and an electrical power transmission line connected to the sensor to transmit power to the sensor. The endoscopic system also can include a floating ground element arranged to provide an electrical reference for the sensor system. Voltage induced by an electromagnetic interference external to the endoscopic system on at least one of the data signal transmission line or electrical power line is substantially similar to the voltage induced by the electromagnetic interference on the floating ground element.

Abstract: An endoscopic system includes a shaft comprising a proximal end portion and a distal end portion; a sensor system; a floating ground element electrically coupled to the sensor system; a power regulator electrically coupled to a power transmission line and to the floating ground element, the power regulator configured to convert ground-referenced power received from an earth ground referenced power source into floating ground element referenced power and to output the floating ground element referenced power through the power transmission line; and a circuit enclosure at least partially enclosing a transceiver circuit and the power regulator, the circuit enclosure being electrically coupled with the floating ground element.

Abstract: An endoscopic system for sensing one or more characteristics at an environment of a worksite comprises a shaft comprising a proximal end portion and a distal end portion; an electrically active sensor system comprising a sensor positioned to sense at least one characteristic of an environment in which the distal end portion of the shaft is located; an electrical power transmission line electrically coupled to the sensor and extending along the shaft, the electrical power transmission line configured to transmit power to the sensor; and a floating ground element electrically isolated from an earth ground and operably coupled to the electrically active sensor system. An overall capacitance between the electrical power transmission line and the floating ground element is greater than an overall capacitance between the floating ground element and earth ground.
