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 SoH, and SoC), calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it.
Smart Battery System ( SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
The call and text message records of hundreds of millions of AT&T cellphone customers in mid-to-late 2022 were exposed in a massive data breach, the telecom company revealed Friday.
Lightning is a proprietary computer bus and power connector, created and designed by Apple Inc. It was introduced on September 12, 2012, in conjunction with the iPhone 5 , to replace its predecessor, the 30-pin dock connector .
A mine-clearing line charge (abbreviated MCLC or MICLIC; pronounced / m ɪ k. l ɪ k / or "mick-lick") is a device used to create a breach in minefields under combat conditions. While there are many types, the basic design is for many explosive charges connected on a line to be projected onto the minefield and then exploded, detonating any ...
Unlike the iPhone 11 Pro and iPhone 11 Pro Max where the only difference was the screen size and battery capacity, the iPhone 12 Pro Max adds a 47% larger sensor and sensor-shift image stabilization to the main camera lens, and replaces the f/2.0 aperture 52 mm telephoto camera lens with a f/2.2 aperture 65 mm lens, allowing for a 2.5x optical ...
Two decades of evolution of mobile phones, from a 1992 Motorola DynaTAC 8000X to the 2014 iPhone 6 Plus. A mobile phone or cell phone [a] is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone).
When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.
