  2. Biological indicator evaluation resistometer - Wikipedia

    en.wikipedia.org/wiki/Biological_indicator...

    A BIER vessel evaluates the resistance of biological indicators to moist heat sterilization. [1] For example, if a 90% reduction is determined to be 5 minutes for the microorganism being evaluated, then a D-value of 5 is assigned. D values are specific to starting bioload, substrate (the material the spores are on), and microbe species.

  3. Silicon bandgap temperature sensor - Wikipedia

    en.wikipedia.org/wiki/Silicon_bandgap...

    The silicon bandgap temperature sensor is an extremely common form of temperature sensor (thermometer) used in electronic equipment.Its main advantage is that it can be included in a silicon integrated circuit at very low cost.

  4. Bioelectrical impedance analysis - Wikipedia

    en.wikipedia.org/wiki/Bioelectrical_impedance...

    Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body.

  5. Varistor - Wikipedia

    en.wikipedia.org/wiki/Varistor

    Metal-oxide varistor manufactured by Siemens & Halske AG. Modern varistor schematic symbol, which is the same as a thermistor symbol [1]. A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [2]

  6. Callendar–Van Dusen equation - Wikipedia

    en.wikipedia.org/wiki/Callendar–Van_Dusen_equation

    The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD).. As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.

    Việt Á Technology Corporation [] (Vietnamese: Công ty Cổ phần Công nghệ Việt Á, lit. 'Vietnam-Asia Technology Joint Stock Company') was considered one of the most prominent companies in the Vietnamese medical technology sector and a major supplier of chemicals and machines for the country's hospitals.

  8. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The analysis of lossless lines provides an accurate approximation for real transmission lines that simplifies the mathematics considered in modeling transmission lines. A lossless line is defined as a transmission line that has no line resistance and no dielectric loss. This would imply that the conductors act like perfect conductors and the ...

  9. Randles circuit - Wikipedia

    en.wikipedia.org/wiki/Randles_circuit

    Randles circuit schematic. In electrochemistry, a Randles circuit is an equivalent electrical circuit that consists of an active electrolyte resistance R S in series with the parallel combination of the double-layer capacitance C dl and an impedance (Z w) of a faradaic reaction.
