    en.wikipedia.org/wiki/IEC_61000-4-2

    IEC 61000-4-2 is the International Electrotechnical Commission's immunity standard on electrostatic discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. [1]

  3. Endoscopic submucosal dissection - Wikipedia

    en.wikipedia.org/wiki/Endoscopic_submucosal...

    Endoscopic submucosal dissection (ESD) is an advanced surgical procedure using endoscopy to remove gastrointestinal tumors that have not entered the muscle layer. ESD may be done in the esophagus, stomach or colon. Application of endoscopic resection (ER) to gastrointestinal (GI) neoplasms is limited to lesions with no risk of nodal metastasis.

  4. Human-body model - Wikipedia

    en.wikipedia.org/wiki/Human-body_model

    Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...

    en.wikipedia.org/wiki/ESD

    ESD (gene), a human gene/enzyme; Electrostatic discharge, a sudden flow of electricity between two electrically charged objects; Electrostatic-sensitive device, any component which can be damaged by common static charges; Energy spectral density, a part of a function in statistical signal processing

  6. Sigmoidoscopy - Wikipedia

    en.wikipedia.org/wiki/Sigmoidoscopy

    Sigmoidoscopy ("sigma", the Greek term for letter "s/ς" + "eidos" + "scopy": namely, to look inside an "s"/"ς"-like object) is the minimally invasive medical examination of the large intestine from the rectum through to the nearest part of the colon, the sigmoid colon.

  7. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    Electrostatic discharge (ESD) is a subclass of electrical overstress and may cause immediate device failure, permanent parameter shifts and latent damage causing increased degradation rate. It has at least one of three components, localized heat generation, high current density and high electric field gradient; prolonged presence of currents of ...

    en.wikipedia.org/wiki/ESD_Simulator

    An ESD simulator, also known as an ESD gun, is a handheld unit used to test the immunity of devices to electrostatic discharge (ESD). These simulators are used in special electromagnetic compatibility (EMC) laboratories.
