85Ring oscillator — A ring oscillator is a device composed of an odd number of NOT gates whose output oscillates between two voltage levels, representing true and false . The NOT gates, or inverters, are attached in a chain; the output of the last inverter is fed… …
86Anton Maria Schyrleus of Rheita — Anton (or Antonius) Maria Schyrleus (also Schyrl, Schyrle) of Rheita (1597 1660) (cs icon Antonín Maria Šírek z Reity) was an astronomer and optician. He developed several inverting and erecting eyepieces, and was the maker of Kepler’s telescope …
87Problem of Apollonius — In Euclidean plane geometry, Apollonius problem is to construct circles that are tangent to three given circles in a plane (Figure 1); two circles are tangent if they touch at a single point. Apollonius of Perga (ca. 262 BC ndash; ca. 190 BC)… …
88Concordance (publishing) — A concordance is an alphabetical list of the principal words used in a book or body of work, with their immediate contexts. Because of the time and difficulty and expense involved in creating a concordance in the pre computer era, only works of… …
89Voltage stabilizer — Unreferenced|date=July 2008A voltage stabilizer is an electronic device able to deliver relatively constant output voltage while input voltage and load current changes over time. The output voltage is usually regulated using a transistor. In a… …
90Buck-boost converter — Two different topologies are called buck boost converter. * The inverting topology The output voltage is of the opposite polarity as the input * A Buck (step down) converter followed by a Boost (step up) converter The output voltage is of the… …
