  2. OBDuino - Wikipedia

    en.wikipedia.org/wiki/OBDuino

    OBDuino is an open source trip computer design based on the Arduino platform. An OBDuino may be assembled and customised by an electronics hobbyist; it displays information such as instantaneous fuel economy (e.g. miles per gallon, L/100 km or kilometres per litre), engine tuning parameters etc. on an LCD.

  3. Battery management system - Wikipedia

    en.wikipedia.org/wiki/Battery_management_system

    A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

  4. Residual-current device - Wikipedia

    en.wikipedia.org/wiki/Residual-current_device

    A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

  5. Battery holder - Wikipedia

    en.wikipedia.org/wiki/Battery_holder

    Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...

  6. Reduced pressure zone device - Wikipedia

    en.wikipedia.org/wiki/Reduced_pressure_zone_device

    They are considered suitable because they prevent both back pressure and back-siphonage, because of a redundant design (even with two check valves broken the device still provides protection), and because they are testable to verify correct operation. RPZDs are often chosen instead of an air gap since the head loss across the RPZD is much smaller.

  7. Readout integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Readout_integrated_circuit

    A readout integrated circuit (ROIC) is an integrated circuit (IC) specifically used for reading detectors of a particular type. They are compatible with different types of detectors such as infrared and ultraviolet.

  8. Inrush current limiter - Wikipedia

    en.wikipedia.org/wiki/Inrush_current_limiter

    The most popular application is the inrush protection of the AC current in switching power supplies (SPS). The primary reason for having surge current suppression in a SPS is to protect the diode bridge rectifier as the input or charging capacitor is initially charged. This capacitor draws significant current during the first half AC cycle and ...

  9. Dashboard - Wikipedia

    en.wikipedia.org/wiki/Dashboard

    Dashboard instruments displaying various car and engine conditions. Where the dashboard originally included an array of simple controls (e.g., the steering wheel) and instrumentation to show speed, fuel level and oil pressure, the modern dashboard may accommodate a broad array of gauges, and controls as well as information, climate control and entertainment systems.
