In control theory, a bang–bang controller ( hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for example a furnace that is either ...
A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk.
Gannett. A 54-year-old convicted sex offender is facing new charges after prosecutors say he sexually assaulted a woman on Milwaukee's east side who defended herself by stabbing him. After his ...
A tower type UPS with one IEC 60320 C14 input and three C13 outlets. A large data-center-scale UPS being installed by electricians. An uninterruptible power supply ( UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
Peak Wildlife Park is a zoo in Winkhill, United Kingdom, and they came up with a fun way to entertain their mob of meerkats. They created their very own rendition of the Super Mario Bros. video ...
Experts say it’s important to get the recommended minimum 0.8 grams of protein per kilogram of body weight a day (a kilogram is equal to 2.2 pounds). For the average person who weighs 150 pounds ...
Beyond the Standard Model. In particle physics, CP violation is a violation of CP-symmetry (or charge conjugation parity symmetry ): the combination of C-symmetry ( charge conjugation symmetry) and P-symmetry ( parity symmetry). CP-symmetry states that the laws of physics should be the same if a particle is interchanged with its antiparticle (C ...
The proton radius puzzle is an unanswered problem in physics relating to the size of the proton. [1] Historically the proton charge radius was measured by two independent methods, which converged to a value of about 0.877 femtometres (1 fm = 10 −15 m). This value was challenged by a 2010 experiment using a third method, which produced a ...
