  2. Electrostatic discharge - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_discharge

    An efficient way to prevent ESD is to use materials that are not too conductive but will slowly conduct static charges away. These materials are called static dissipative and have resistivity values below 10 12 ohm-meters. Materials in automated manufacturing which will touch on conductive areas of ESD sensitive electronic should be made of ...

  3. Electrostatic discharge materials - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_discharge...

    Conductive Static Dissipative Anti-Static Insulative: Description Carbon powders and fiber: No initial charge. Provides path for charge to bleed off. Typically black color. No or low initial charge. Prevents discharge to or from human contact Initial charges are suppressed. Typically pink color. Insulators and Base Polymers. Not an ESD material

  4. Dissipative system - Wikipedia

    en.wikipedia.org/wiki/Dissipative_system

    Dissipative systems theory has been discussed by V.M. Popov, J.C. Willems, D.J. Hill, and P. Moylan. In the case of linear invariant systems [ clarification needed ] , this is known as positive real transfer functions, and a fundamental tool is the so-called Kalman–Yakubovich–Popov lemma which relates the state space and the frequency ...

  5. Static electricity - Wikipedia

    en.wikipedia.org/wiki/Static_electricity

    Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]

  6. Pain theories - Wikipedia

    en.wikipedia.org/wiki/Pain_theories

    In 1894 Goldscheider extended the intensive theory, proposing that each tactile nerve fiber can evoke three distinct qualities of sensation – tickle, touch and pain – the quality depending on the intensity of stimulation; and extended Naunyn's summation idea, proposing that, over time, activity from peripheral fibers may accumulate in the ...

  7. Antistatic bag - Wikipedia

    en.wikipedia.org/wiki/Antistatic_bag

    Conductive antistatic bags are manufactured with a layer of conductive metal, often aluminum, [3] and a dielectric layer of plastic [2] covered in a static dissipative coating. This forms both a shield and a non-conductive barrier, shielding the contents from static charge via the Faraday cage effect.

  8. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    The electrostatic field (lines with arrows) of a nearby positive charge (+) causes the mobile charges in conductive objects to separate due to electrostatic induction. Negative charges (blue) are attracted and move to the surface of the object facing the external charge. Positive charges (red) are repelled and move to the surface facing away ...

  9. Pain and pleasure - Wikipedia

    en.wikipedia.org/wiki/Pain_and_pleasure

    The opponent-process theory is a model that views two components as being pairs that are opposite to each other, such that if one component is experienced, the other component will be repressed. Therefore, an increase in pain should bring about a decrease in pleasure, and a decrease in pain should bring about an increase in pleasure or pain relief.
