Batterygate[ 1][ 2][ 3] is a term used to describe deliberate processor slowdowns on Apple 's iPhones, in order to prevent handsets with degraded batteries shutting down when under high load. Critics argued the slowdown amounted to planned obsolescence, however this may stem from the common misconception that all older iPhones were slowed down.
Resonant inductive coupling or magnetic phase synchronous coupling[ 4][ 5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [ 5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a power source with internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals. Moritz von Jacobi published the maximum power (transfer) theorem around 1840; it is also ...
Convolutional code with any code rate can be designed based on polynomial selection; [15] however, in practice, a puncturing procedure is often used to achieve the required code rate. Puncturing is a technique used to make a m/n rate code from a "basic" low-rate (e.g., 1/n) code. It is achieved by deleting of some bits in the encoder output.
Droop speed control. Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid.
The iPhone 7 and iPhone 7 Plus [a] are smartphones that were designed, developed, and marketed by Apple Inc. They are the tenth generation of the iPhone.They were announced on September 7, 2016, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, and were released on September 16, 2016, succeeding the iPhone 6, iPhone 6 Plus, iPhone 6S and iPhone 6S Plus as the flagship ...
Diesel generator on an oil tanker. The packaged combination of a diesel engine, a generator, and various auxiliary devices (such as base, canopy, sound attenuation, control systems, circuit breakers, jacket water heaters, and starting system) is referred to as a "generating set" or a "Genset" in short. Set sizes range from 8 to 30-kW (also 8 to ...
Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery. This process is less efficient than the flywheel. The efficiency of the generator can be represented by:
