WiTricity is a technology that allows the wireless transmission of electrical energy without the use of wires. It works through magnetic field resonance and was first proposed in the 1890s by Nikola Tesla, who demonstrated wireless power transmission over long distances. However, the idea was forgotten until researchers at MIT, led by Marin Soljačić, worked to develop the technology in the 2000s. WiTricity uses magnetic fields to transmit power efficiently over short ranges and has potential applications to replace wired power connections. While the technology is considered safe, efficiency decreases with distance and exact resonance is required between transmitter and receiver.

Abstract
1. The document discusses wireless electricity or "witricity", which is the transfer of electric power over distance without wires. It can be done using coupled magnetic resonators to efficiently transfer power in non-radiating fields.
2. Witricity allows devices to be charged without plugging in, and could eliminate the need to replace batteries. Power is transmitted from a charging coil through an inductive magnetic field to a receiving coil.
3. For efficient wireless power transfer, the transmitting and receiving coils must be in "strongly coupled" magnetic resonance. This allows energy to be exchanged efficiently even over some distance between the coils.

Fayaz-witricity
Witricity is a wireless electricity technology developed at MIT that uses magnetic resonance to efficiently transfer power between two resonant objects over short distances, without wires. It works by generating an oscillating magnetic field from a power source coil which induces a magnetic field in a receiving coil linked by resonance. This resonant coupling allows efficient energy transfer over distances greater than traditional induction methods. The inventors validated the theory by powering a 60-watt light bulb suspended two meters from the power source coil, demonstrating its potential for wirelessly charging electronic devices without contact.
wireless power transmission via solar power satellite
Wireless energy transfer uses magnetic fields or microwaves to transmit electricity between two objects over short or long distances without wires. Nikola Tesla pioneered this concept in the late 1890s by transmitting energy wirelessly over 40 km. While promising for reducing transmission losses, challenges remain for large-scale adoption including high costs and potential health effects. Space-based solar power satellites aim to overcome some issues by collecting solar energy in space for wireless transmission to Earth.
Wireless Power Transmisson
Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to
an electrical load without a conductive physical connection. In this paper the technologies available for
Wireless Power Transmission (WPT) and its future possible advancements is being discussed to assume its
feasibility in actual practices.
In our present electricity system much of the power generated is wasted during transmission from power
plants to the consumers passing through cables, substations, etc. With WPT the need for inefficient and
costly, cables, towers, and substations will be eliminated & so will the power losses, finally reducing the
cost of energy. This is one such technology that can make the transmission system highly efficient &
economical. One mere demerit of WPT is that it develops reactive power at a small frequency that is very
biologically compatible and harmful to environment & living beings on over exposure.

witricity
WiTricity is a technology developed by researchers at MIT that enables the wireless transfer of electrical energy between devices without wires. It works by using magnetic resonance between self-resonating copper coils, allowing power to be transmitted across short air gaps from a transmitter source to a receiver device. While the concept of wireless power transfer has existed since the 19th century, WiTricity could allow for practical and safe applications like wirelessly charging phones, laptops and other devices. However, more research is still needed to improve efficiency and develop commercial systems.
Microwave wireless power transmission system
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite overhead conductors and underground cables that use high temperature super conductor. But, the transmission is still inefficient. According to the World Resources Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%,40% and greater than 40%. This is attributed to technical losses (grid’s inefficiencies) and theft. Any problem can be solved by state of the art technology. The above discussed problem can be solved by choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.

Transmission of Wireless Power using Solar Power satellite Technology
As we know that Sun is the great source of energy on the earth & we cant even imagine the life of any living organisms on the earth .Energy can be produced in three modes 1.Induction(In which two bodies are not connected together but even there is requirement of medium ) 2. Conduction (In which bodies are in contact with each other & it also requires medium) 3.Radiation(In which there is no contact of bodies but energy transmitted in form of photons). Solar energy is radiant light & heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating ,photovoltaic, solar thermal energy .It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar on how they capture and distribute solar energy or convert it into solar power. Wireless Power transmission (WPT) is a useful and convenient technology that can be employed to collect solar energy and concentrate on earth surface without the need for a wire connection called a solar power satellites (SPS). This paper provides an analysis of wireless power transfer with an assessment of its practical applicability in terms of power range and efficiency. In this paper, various technologies available so far for wireless transmission of electricity and the need for a Wireless Energy Transmission will be discussed to find its possibility in actual practices. Also, their advantages, disadvantages and economical consideration will also be presented. This paper concentrates mainly on (i) The most popular concept known as Tesla Theory, (ii) The microwave power transmission(MPT) called Solar power satellite, and (iii) The highly efficient fibre lasers for wireless power transmission. Many concepts, research papers, and patents are available on wireless transmission of electricity but the commercial technologies are yet to be materialized. This paper will also discuss the possible ways to get useful and practical results out of all researches carried out so far elsewhere. The output microwave power ranges from 50W to 200W at 2.45GHz. A coaxial cable is to connect 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.

In 2007, a group of MIT scientists led by Marin Soljacic revived the concept and developed an efficient wireless power system. WiTricity works by using magnetic resonance to transmit electric current from a transmitting coil to a receiving coil within a few meters without wires. While it provides advantages like eliminating wires and batteries, challenges remain in improving efficiency and increasing the range of wireless power transmission.
Witricity ppt
Wireless power transmission involves transmitting electric power through the air without wires. In 1899, Nikola Tesla proposed a method of wireless power but achieved only 15% efficiency due to using radiative transmission. In 2007, MIT engineers developed a method using resonant induction that powered a 60W lightbulb from 7 feet away at 40% efficiency, demonstrating practical wireless power transfer. Wireless power works by powering a magnetic coil that transmits electromagnetic waves to a receiving coil which absorbs the energy and uses it to charge a device. While wireless power eliminates wires, its range is limited to a few meters and efficiency is around 40%.

Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

- 7. In 1890, Sir Nikola Tesla proposed WPT Light 200 lamps over 25 miles away in 1899 Radioactive mode, power wasted and less efficiency. History of Wireless Power Fig: Nikola Tesla Fig: WPT House
- 8. The Forgotten Invention Is Reborn The idea of wireless electricity and Tesla coil was forgotten in the early years. A group of MIT scientists, led by Marin Soljačić worked on it and named it "WiTricity“ MIT powered 60 watt light bulb from 2 meters (7 ft) at 40% efficiency. Fig: Marin Soljačić and His Team
- 9. Is WiTricity Technology safe? Non- radioactive modeof energy transfer. Magneticfieldsinteractvery weaklyand scientifically regarded to besafe. WiTricity productsarebeing designedto complywith applicable safetystandards andregulations.
- 10. Limitations Transmissions possible only in fewmeters. Possibility of “energy theft”. Efficiency decreases with distance. The resonance condition should be satisfied and if any error exists, there is no possibility of power transfer.
