An aspect of the present disclosure provides a vehicle which includes: an electrostatic eliminator that reduces a positive charge of a specific portion or that charges the specific portion with a negative charge, the specific portion being defined as a portion to be positively charged at which a positively charged air flow that flows around a vehicle body during travel starts to vary from a flow along a surface of the positively charged vehicle body to a flow separated from the surface as negative charges are accumulated because of the external factors. The specific portion is constituted from a conductive material with a surface resistance value that is less than a surface resistance value of the electrostatic eliminator. The electrostatic eliminator is constituted from a conductive resin with a surface resistance value in a range of 10.sup.2Ω or more and less than 10.sup.11Ω.

A blade angle feedback ring assembly for an aircraft engine propeller having adjustable angle blades is provided. The feedback ring assembly comprises a feedback ring coupled to rotate with the propeller, the engine configured such that a first electrically-conductive path is defined between the propeller and the engine via the feedback ring, and an electric current conduction element provided between the propeller and the engine to define a second electrically-conductive path between the propeller and the engine in parallel to the first path, the second electrically-conductive path configured with a lower electrical resistance to conduction between the propeller and the engine than the first electrically-conductive path.

The present disclosure provides a technology which can suppress separation of an airflow while a change in an appearance of a vehicle is suppressed. This exemplary embodiment is a vehicle including a self-discharging static eliminator which neutralizes and eliminates positive charges generated on a vehicle body by self-discharging which causes negative air ions to be generated and a transparent conductive material, and the self-discharging static eliminator and the transparent conductive material are electrically continuous.

An electrostatic discharge (ESD) robust design for an input device such as a stylus is disclosed. The input device can include one or more components, such as one or more Schottky diodes, that can be damaged by ESD events. To reduce the likelihood of damage to sensitive components, the parasitic capacitance between sensitive conductive paths and reference ground paths of the input device that could otherwise provide electrostatic discharge paths can be reduced (arranging current limiting resistance at specific locations among sensitive components, creating physical separation between sensitive conductive paths and reference ground paths), shielding can be added to shield the sensitive electronics from ESD pulses, and high dielectric breakdown material can be added to prevent ESD pulse entry or exit of not otherwise protected circuit parts.

This application is directed to dielectric isolation of fluid conveyance systems both Aerospace and Industrial. The dielectric isolator 5 serves to both prevent high voltage surges transitioning down the conveyance distribution system and second as a means to conduct fluid under pressure. This application address the limitations of current art by approaching the challenge as a pure electrical solution. High resistance precision electrical elements 10 are integrated into a one piece high dielectric material housing 15 which embodies the required end fitting interface. Conductive end collars 20 bonded in position to housing 15 and in contact with resistive elements 10, provides the means for conducting electrical energy to the system interface fitting, coupling or connection. The application provides precision resistance from one unit to the next with built in triple redundancy for high life expectation. The application has the ability to withstand high voltage surge up to 30,000 Volts and by virtue of integrated end ferrules eliminates internal arcing and provides a leak proof design.
