The proliferation of portable wireless communication devices such as mobile phones, tablet, and laptop computers in recent decades is currently driving the development of mid-range wireless powering and charging technology to eliminate the need for these devices to be tethered to wall plugs during charging.

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 vehicles, power tools, electric toothbrushes, and medical devices.
The resonant circuits were coils of copper wire which resonated with their internal capacitance (dotted capacitors) at 10 MHz. Power was coupled into the transmitter resonator, and out of the receiver resonator into the rectifier, by small coils which also served for impedance matching. In this regard, MIT researchers believe they discovered a ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
In backscatter modulation, the power-receiver coil is loaded, changing the current draw at the power transmitter. These current changes are monitored and demodulated into the information required for the two devices to work together. [2] In 2011, the Wireless Power Consortium began to extend the Qi specification to medium power. [11]
The system consists of a transmitter and a receiver. Transmitter connects to a standard power outlet and converts electricity into infrared laser beam. Receivers use a miniature photo-voltaic cell to convert transmitted light into electrical power. Receivers can be embedded into a device or connected into an existing charging port.
It shows a variety of creative tools and objects such as a camera, guitar, piano and paint being destroyed by an industrial crusher. Apple apologizes for iPad Pro 'Crush' ad, Ad Age says Skip to ...
Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching of electronics technician and electronics engineering programs.
