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.
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 ...
The game port is a device port that was found on IBM PC compatible and other computer systems throughout the 1980s and 1990s. It was the traditional connector for joystick input, and occasionally MIDI devices, until made obsolete by USB in the late 1990s. Originally located on a dedicated Game Control Adapter expansion card, the game port was ...
Biden has also proposed raising the Medicare payroll tax for people earning more than $400,000 from 0.9 percent to 2.1 percent to further support the program. During his 2020 campaign, he proposed ...
Programmable interrupt controller. In computing, a programmable interrupt controller ( PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQs) coming from multiple different sources (like external I/O devices) which may occur simultaneously. [1] It helps prioritize IRQs so that the CPU switches ...
Wide-open windows, morning coffee on the deck, mosquitos sneaking in a cracked screen door, and fruit flies trying to move to occupy your kitchen. While the former are delightful, the latter, we ...
Almost 40% reported jiggling their computer mouses to make it appear they’re active online, and just as many said they sent emails outside work hours to create the illusion they’re working ...
A specially developed CCD in a wire-bonded package used for ultraviolet imaging. A charge-coupled device ( CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology ...
