This document proposes a system to automatically recharge mobile phones through microwave transmission as the phone is being used. The system would transmit microwave signals from an antenna along with voice signals. Mobile phones would require minor additions like a sensor, rectenna, and filter to receive the microwave energy and use it to charge the phone battery. This would eliminate the need for separate chargers and allow the phone to charge as it is being used through voice calls. Manufacturers could remove talk time and battery life from phone specifications as a result.
BRIEF DESCRIPTION:
This simple touch sensitive alarm is developed by using NE-555 timer IC, operated as a monostable vibrator.
This touch alarm circuit will sound when somebody touches the trigger plate. Touch the sensing plate of the alarm with your finger and it starts beeping and then stops.
Touching it again and it goes again!
Here the stable stage is low, so the timer outputs low after the trigger is removed. Basically the circuit has a led which turns on when we touch a pin of timer. The led will be on for the time during which the trigger is present. Once the trigger is removed the led turns off.
This is a little and flexible circuit consists of a touch sensor and a NE-555 IC with a small buzzer as the output load. Two touch sensor strips of metal are mounted side by side & connected to the input of the circuit.

Cell Phones are a piece of our life. It is the quickest and the most straightforward medium of correspondence. Battery life of cell telephone is dependably been an issue for makers. Individuals are griping about their versa tile’s battery life, that they don't have long battery life furthermore they need to charge their telephone a few times. In this paper another thought is indicated to charge your cell telephone anyplace you need without associating its charger. This is carried out utilizing microwaves. Microwaves are the radio waves which give correspondence between two cell telephones. The microwave is sent with the message by the transmitter utilizing radio wire at the recurrence of 2.45 GHz. Here we are utilizing Microwaves as the wellspring of vitality to charge the telephone. We need to include a sensor, a rectenna circuit and a filer in our cell telephone to do the employment. By including these things we can charge our telephone utilizing microwave when we talk. So as we talk more we can charge more!!

WIRELESS CHARGING
INTRODUCTION Always the recharging of mobile phone batteries has always been a problem for us. This problem will be solved after our proposal………!!!!!!!! In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone!
3. The microwave signal is transmitted from the transmitter along with the message signal using special kind of antennas called slotted wave guide antenna at a frequency is 2.45 GHz Thus the more you talk, the more is your mobile phone charged!!!!!!! This is new isn’t?!!
4. What Is Microwaves????? Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke. Shorter microwaves are used in remote sensing. These microwaves are used for radar like the Doppler radar used in weather forecasts
5. Microwaves > Frequency Range: 3GHZ to 300GHZ > Remort Sensing. > Communication Industry. >2.45GHZ ISM Band.
6. TRANSMITTER DESIGN The MAGNETRON is a self-contained microwave oscillator that operates differently from the linearbeam tubes, such as the TWT and the klystron. ——Magnetron is used to produce high-power output required in radar and communications equipment —Microwaves used in mobile communication are also produced by similar Oscillators
7. Magnetron - Construction
8. PRINCIPLE OF OPERATION
9. WHAT’S RECTANNAE??? What’s rectannae you are confused…….it’s nothing but the combination of rectifier and antenna. Antenna is to receive the microwave signal and it just feed the signal to rectifier . Rectifier is to convert the AC signal to PULSATING DC signal.
10. RECEIVER DESIGN The basic addition to the mobile phone is going to be the rectenna. A rectenna is a rectifying antenna, a special type of antenna that is used to directly convert microwave energy into DC electricity.
11. ADVANTAGES Use of separate chargers is eliminated. Electricity is saved The phone can be charged anywhere anytime. Wireless energy transfer can potentially recharge the mobile phones without chords. Only one microwave transmitter can serve to all the service providers in that area. The need of different types of chargers by different manufacturers is totally eliminated.
12. DISADVANTAGES The transmitter and receiver also should be very powerful devices as the distance increases. Slower Charging. Wireless transmission of the energy causes some drastic effects to human body, because of its radiation. More costly.
The main objective of this current proposal is to make the recharging of the mobile phones independent of their manufacturer and battery make. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone!
The microwave signal is transmitted from the transmitter along with the message signal using special kind of antennas called slotted wave guide antenna at a frequency is 2.45 GHz
There is great need to limit the use of cell phone at particular places
and at particular times. Hence, the use of intelligent cell phone detector is
guaranteed. This work concentrates in designing a system that will dictate the
presence of GSM signals from an unauthorized user in restricted areas which
will in turn trigger another device to restrict the user from service

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

ABSTRACT
Mobile phones becoming a basic part of life, the recharging of mobile phone batteries
have always been a problem. The mobile phones vary in their talk time and battery
standby according to their manufacture and batteries. All these phones irrespective of
their manufacturer and batteries have to be put to recharge after the battery has drained
out. The main objective of this current proposal to make their charging of the mobile
phones independent of their manufacturer and battery make. A new proposal has been
made so as to make the recharging of the mobile phones is done automatically as you talk
in your mobile phone. This done by using microwaves.
The microwave signal is transmitted from the transmitter along with the message
signal using special kind of antennas called slotted waveguide antenna at a frequency is
2.45GHZ. There are minimal additions, which have to be made in the mobile handsets,
which are the addition of a sensor, a rectenna and a filter. With the above setup, the need
for separate chargers for mobile phones is eliminated and makes charging universal. Thus
the more you talk, the more is your mobile phone charge. With this proposal the
manufacturers would be able to remove the talk time and battery standby from their
phone specifications.
