  2. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge. Chargers may elevate the output voltage proportionally with current to compensate for impedance in the wires. [3]

  3. Sign-on and sign-off - Wikipedia

    en.wikipedia.org/wiki/Sign-on_and_sign-off

    The sign-off sequence may include some or all of the following stages, but not necessarily in this order: An announcement informing viewers that the station is about to go off-air: it may also include a message of thanks for the viewer's patronage, along with an announcement of the time when the station is scheduled to sign on again.

  4. Power-on reset - Wikipedia

    en.wikipedia.org/wiki/Power-on_reset

    A simple PoR uses the charging of a capacitor, in series with a resistor, to measure a time period during which the rest of the circuit is held in a reset state. A Schmitt trigger may be used to deassert the reset signal cleanly, once the rising voltage of the RC network passes the threshold voltage of the Schmitt trigger. The resistor and ...

  5. 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 ...

  6. Inductive charging - Wikipedia

    en.wikipedia.org/wiki/Inductive_charging

    The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power ...

  7. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [7] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.

  8. Viera Cast - Wikipedia

    en.wikipedia.org/wiki/Viera_Cast

    Viera Cast is a Smart TV platform by Panasonic that makes it possible to stream multimedia content from the Internet directly into select Viera HDTVs and Blu-ray players. It was announced during the January 2008 exhibition of the Consumer Electronics Show (CES) in Las Vegas [1] and began rolling out in Panasonic Viera TVs several months later.

  9. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
