  2. Charge pump - Wikipedia

    en.wikipedia.org/wiki/Charge_pump

    A common application for charge-pump circuits is in RS-232 level shifters, where they are used to derive positive and negative voltages (often +10 V and −10 V) from a single 5 V or 3 V power supply rail. Charge pumps can also be used as LCD or white-LED drivers, generating high bias voltages from a single low-voltage supply, such as a battery.

    For example, if this is session 0, boxes 0-2-5-9, 1-3-6-0, 5-7-0-4, and 8-0-3-7 are done because they all contain the number 0. If a reviewed card isn't successful, it moves back to Deck Current. If a reviewed card is successful and the last number of its box matches the current session number, then that card moves to the Retired Deck.

    en.wikipedia.org/wiki/Borg-Warner_35_transmission

    The selector lever varies depending on years and car models the transmission is used in. All models follow a quadrant which has six stations. Early models have two drive positions marked with a "2" and a "1" (P-R-N-D2-D1-L; Park, Reverse, Neutral, D2, D1 and Lock). These models start off in Second gear when in the D2 position.

  8. Crowbar (circuit) - Wikipedia

    en.wikipedia.org/wiki/Crowbar_(circuit)

    A crowbar circuit is an electrical circuit used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o ), like dropping a crowbar across the output terminals of the power supply.
