This project explains a simple wireless battery charger circuit that charges your mobile when placed near the transmitter.
This circuit may be used as wireless power transfer circuit, wireless mobile charger circuit, wireless battery charger circuit, etc.
Any training class is a considerable investment in terms of cost and your time. You can’t afford to waste any of your precious time and you need to attend something that is useful and improves your productivity. After five years of presentation throughout the world, this workshop is well polished, practical and relevant.
The aim of this workshop is to help you identify, design, prevent and fix common EMI/EMC problems with a focus on earthing and shielding techniques. Learning how to fix earthing and shielding problems on the job can be very expensive and frustrating. Although it must be noted that most of the principles involved are simple, this workshop will give you the tools to approach earthing and shielding issues in a logical and systematic way.
This workshop focuses on the issues of interest to you if you are working in design, operation or maintenance of analog or digital systems involving sensors, data acquisition, process control, cables, signal processing, programmable logic controllers, power distribution, high speed logic etc.
The circuit board layout section concentrates on design and layout of circuits and components on a printed circuit board. The overall focus is on useful design and systems issues; not about regulations and standards. The idea is that you will take this material back with you to your work and apply the key principles immediately to your design and troubleshooting challenges.

Wireless charging (also known as " Inductive charging ") uses an electromagnetic field to transfer energy between two objects.
This is usually done with a charging station.
Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
Voice Transmission System Based on Laser Torchijtsrd
This paper is designed for voice transmission system based on laser torch. In this system, it has two parts transmitting section and receiving section. The transmitting section mainly comprises with condenser microphone, IC 741, BC 548, BD 139 and laser torch. The receiving section composes with L14f1 photo transistor, LM 386 and Loud speaker. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The gain of the op amp can be controlled with the help of 1 mega ohm pot meter variable resistor. The AF output from the amplifier is coupled to the base of transistor BD 139, which in turn, modulates the laser beam. The receiver circuit uses NPN photo transistor as the light sensor that is followed by two stage transistor preamplifier and LM 386 based audio power amplifier. The receiver does not need any complicated alignment. The photo transistor is kept towards the remote transmitter's laser point and the volume control is adjusted for a clear sound.

Presentation on emc testing and measurementRajat Soni
discuss the options for EMC testing for compliance with the EMC Directive from the point of view of a manufacturer who wishes to achieve as much progress as possible, in-house, on a limited budget. It is not addressed to test houses nor to those manufacturers who have the resources to emulate most or all of the facilities of an accredited test house in their own premises. There are many small-to-medium sized enterprises who are able to dedicate a modest budget of several thousands or tens of thousands of pounds to an in-house EMC test set-up and who wish to gain the maximum benefit from so doing.
An optical fiber attenuator is an optical device that can be used to attenuate the input power to avoid distortion of the optical receiver due to excessive power.How does it work? HYC can provide various types of fixed female and male optical fiber attenuators with stable performance and reliable quality, which can meet the requirements of various connector interface types and working wavelength customization of ST, SC, FC, MU, and LC.

Design and Fabrication of S-Band MIC Power Amplifierijcisjournal
In this paper, we demonstrate an approach to design FET (pHEMT) based amplifier. The FET is from
Berex Inc.The design is carried out using the measured S-parameter data of the FET.ADS is used as design
tool for the design. A single-stage power amplifier demonstrated 13dB output gain from 3GHz-4GHz .The
saturated output power of 1W and the power added efficiency (PAE) up to 43%.The amplifier is fabricated
on a selective device GaAs power pHEMT process in MIC (Microwave Integrated Circuit) Technology.
MICs are realized using one or more different forms of transmission lines, all characterized by their ability
to be printed on a dielectric substrate.Active and passive components such as transistors/FET, thin or thick
film chip capacitors and resistors are attached
While an EMAT (Electro Magnetic Acoustic Transducer) in its simplest form is comprised of a magnet and an RF coil used to generate sound by electromagnetic induction in materials it is actually a rather complex system where each part of the sensor and instrumentation needs careful optimization for application specific performance. Historically EMAT inspection has suffered in widespread use because of a fundamental problem with the technology which is transducer inefficiency. EMAT requires very high power and very precise electronic designs to generate and
detect the signals.
