A presentation on wireless charging.
Inductive charging (also known as wireless charging or cordless charging) uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. 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.
Induction chargers use an induction coil to create an alternating electromagnetic field from within a charging base, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery. The two induction coils in proximity combine to form an electrical transformer Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.
Recent improvements to this resonant system include using a movable transmission coil (i.e. mounted on an elevating platform or arm) and the use of other materials for the receiver coil made of silver plated copper or sometimes aluminium to minimize weight and decrease resistance due to the skin effect.
Wireless Charging which is technically called as Inductive charging uses an electromagnetic field to transfer energy between two objects. This is actually done with the help of a charging station. Energy transferred can then be used to charge batteries or run the device.

The output microwave power ranges from 50 W to 200 W at 2.45 GHz. A coaxial cable connects the output of the microwave source to a coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected power. The circulator is connected to a tuning waveguide section to match the waveguide impedance to the antenna input impedance. The slotted waveguide antenna consists of 8 waveguide sections with 8 slots on each section. These 64 slots radiate the power uniformly through free space to the rectenna. The slotted waveguide antenna is ideal for power transmission because of its high aperture efficiency Key words – Wireless transmission, Tesla theory, Microwave power transmission, Fiber lasers, Collaborative research.
Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor.
The most common wireless technologies use radio
Wireless charging is making inroads in the healthcare, automotive and manufacturing industries because it offers the promise of increased mobility and advances that could allow tiny internet of things (IoT) devices to get power many feet away from a charger.
In wireless charging the current coming from the wall power outlet moves through the wire in the wireless charger, creating a magnetic field. The magnetic field creates a current in the coil inside the device. This coil is connected to the battery and the current charges the battery. The two induction coils in proximity combine to form an electrical transformer.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. Before the introduction of VLSI technology most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.
The History of the transistor dates to the mid-1920s when several inventors attempted devices that were intended to control current in solid-state diodes and convert them into triodes. Success came after World War II, when the use of silicon and germanium crystals as radar detectors led to improvements in fabrication and theory. Scientists who had worked on radar returned to solid-state device development. With the invention of transistors at Bell Labs in 1947, the field of electronics shifted from vacuum tubes to solid-state devices.
With the small transistor at their hands, electrical engineers of the 1950s saw the possibilities of constructing far more advanced circuits. However, as the complexity of circuits grew, problems arose.
One problem was the size of the circuit. A complex circuit like a computer was dependent on speed. If the components were large, the wires interconnecting them must be long. The electric signals took time to go through the circuit, thus slowing the computer.
The Invention of the integrated circuit by Jack Kilby and Robert Noyce solved this problem by making all the components and the chip out of the same block (monolith) of semiconductor material. The circuits could be made smaller, and the manufacturing process could be automated. This led to the idea of integrating all components on a single silicon wafer, which led to small-scale integration (SSI) in the early 1960s, medium-scale integration (MSI) in the late 1960s, and then large-scale integration (LSI) as well as VLSI in the 1970s and 1980s, with tens of thousands of transistors on a single chip (later hundreds of thousands, then millions, and now billions (109)).
In telecommunication, Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is the upgre path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
LTE is commonly marketed as 4G LTE, but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series, for LTE Advanced. The requirements were originally set forth by the ITU-R organization in the IMT Advanced specification. However, due to marketing pressures and the significant advancements that WiMAX, Evolved High Speed Packet Access and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies. The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced.[4] To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".
Engineering is the application of mathematics, as well as scientific, economic, social, and practical knowledge to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations.
The discipline of engineering is extremely broad and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
The term Engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise". The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation or safety to life and property.
Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel and pulley. Each of these inventions is essentially consistent with the modern definition of engineering.
The term engineering is derived from the word engineer, which itself dates back to 1390 when an engine'er (literally, one who operates an engine) originally referred to "a constructor of military engines." In this context, now obsolete, an "engine" referred to a military machine, i.e., a mechanical contraption used in war (for example, a catapult). Notable examples of the obsolete usage which have survived to the present day are military engineering corps, e.g., the U.S. Army Corps of Engineers.
The word "engine" itself is of even older origin, ultimately deriving from the Latin ingenium (c. 1250), meaning "innate quality, especially mental power, hence a clever invention."
Later, as the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the discipline of military engineering.
Light Fidelity(Li-Fi) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication(Wi-Fi or Cellular network), or even a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than some Wi-Fi implementations,reaching speeds of 224 giga bits per second. It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.
A brief presentation on 3D Printing technology.
3D printing is the technology to print layout of any design to check the accuracy of the design before implementing the same on a large scale design in order to save time and money. The procedure of the same is quite easy and can be carried out with great efficiency. Almost all designs can be formed using this technique unless it is too complex.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

4. WHAT IS WIRELESS CHARGING?
Wireless charging is one of the several methods of
charging batteries without the use of cable or
device specific AC adaptors.
Wireless charging can be used for a wide variety of
devices including cell phones laptop computers and
MP3 players as well as larger objects such as
robots and electric cars.
5. METHODS OF CHARGING
There are three types of wireless charging :-
Resonance Charging
Inductive Charging
Radio Charging
6. RESONANCE CHARGING
It uses phenomenon of “RESONANCE”, that
causes an object to vibrate when energy of certain
frequency is applied.
Two copper coils are used one attached to
transmitter & another to receiver.
Both coils are tuned to same electromagnetic
frequency.
These coils when placed close to one another
power is transferred.
7. EXAMPLES:-
Electric cars
Robots
Vacuum Cleaners
Laptop computers &
Other items that require large amounts of power.
8. INDUCTIVE CHARGING
Inductive charging is one kind of short distance
wireless charging.
This method works on the principle of
“ELECTROMAGNETIC INDUCTION” where the
charger device will create an E.M field with
alternating polarity using a coil of insulated copper
wire & a similar coil will be placed inside the mobile
device which will convert E.M field back to electric
current there by charging the battery.
9. EXAMPLES:-
MP3 players.
Personal Digital Assistants (PDA’s).
Electric toothbrushes.
Waterproof Vibrating Razors. &
Other mid-sized items
10. RADIO CHARGING
This method is on the basis that Radio Waves are
widely in use to transmit and receive cellular telephone,
television, radio and Wi-Fi.
A Radio wave once transmitted, propagates in all
directions until it reaches an antenna tuned to proper
frequency to receive it.
A transmitter plugged in to a socket, generates radio
waves, when the receiver attached to the device is set
to the same frequency as the transmitter, it will charge
the device’s battery.
11. EXAMPLES:-
Watches.
Hearing aids.
Medical implants.
Cell phones.
Wireless keyboards &
Other charging devices with small batteries and
low power requirements.
12. DESIGN OVERVIEW
The basic design mainly consists of three sole
parts:
Transmitter
Antenna
Receiver
13. TRANSMITTER
A power transmitter acts as a power source.
It will transmit power to the receiver side.
The transmission signals are mainly in
between the RF/Microwave range. (Typically
900Mhz)
14.
15. ANTENNAS
It plays an important role of mediator between transmitter &
receiver.
Important specifications:
1.Impedance of antenna.
2.Gain of antenna.
Impedance of antenna should match o/p impedance of power
transmitter and i/p impedance of rectifier ckt.
Higher gain yields better result of design.
16. RECEIVER
The receivers main purpose is to charge an AAA battery.
For charging AC signal (microwave signal with a typical value
of 900 MHz) is taken and fed to a rectifier ckt to get a D.C
signal.
A full-wave rectifier ckt is used because of its simplicity and
efficiency in converting A.C signal.
At the o/p of the rectifier, the signal is not a D.C signal yet.
Thus by adding a capacitor and a resistor a smooth o/p can
be achieved.
21. 2) Radio Charging.
Dual Charging Stereo FM Clock Radio with Lightning Connector
and USB for iPhone 6
22. BENEFITS
Provides consumers with freedom and
convenience.
The way the technology works is simple.
Simultaneous charging of multiple devices.
The plastic, packaging & electronic waste
associated with charges is greatly reduced.
Since it is wireless it is economic.
23. LIMITATIONS
applicable for only small distance
For the larger devices like electric car ,
charging stations may be limited
Efficiency and power loss are the major
problems
24. CONCLUSIONS:
Technology has done many new inventions. The
technology provides a wide range of other obvious
benefits, including better portability, lower cost and
best of all the end of having to guess which charger
go what gadgets. Charging will one day become a
simple matter of dropping devices into the nearest
charging ad.
