The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...
A line-interactive UPS maintains the inverter in line and redirects the battery's DC current path from the normal charging mode to supplying current when power is lost. In a standby ("off-line") system the load is powered directly by the input power and the backup power circuitry is only invoked when the utility power fails.
While performance can be temporarily increased when the computer is not hot (overclocking), [33] in order to protect the hardware from excessive heat, the system will automatically reduce performance or shut down the processor if necessary. [32] Processors also will shut off or enter a low power mode when inactive to reduce heat. [34]
A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
Some versions of macOS (such as OS X Lion) display a black screen of death instead of a kernel panic in the event of a hardware or software failure. This is usually pointed to a graphics card failure or a sleep/wake issue. [9]
The Boeing 787 Dreamliner experienced an integer overflow bug which could shut down all electrical generators if the aircraft was on for more than 248 days. [53] A similar problem was found in Airbus A350 which need to be powered down before reaching 149 hours of continuous power-on time, otherwise certain avionics systems or functions would ...
Doomwatch is a British science fiction television programme produced by the BBC, which ran on BBC1 between 1970 and 1972. [2] The series was set in the then present day, and dealt with a scientific government agency led by Doctor Spencer Quist (played by John Paul), responsible for investigating and combating various environmental and technological dangers.
The Macchi C.205 Veltro (Italian: Greyhound) (also known as MC.205, "MC" standing for "Macchi Castoldi") was a Second World War-era fighter aircraft designed and produced by the Italian aircraft manufacturer Aeronautica Macchi.
