WIRELESS POWER TRANSFER
This document summarizes a project to develop a system for wireless power transfer for medical applications such as charging pacemaker batteries without wires. The system works by taking household AC power at 230V/50Hz and converting it to AC power at 20kHz and 12V using a transformer. This power is then rectified, filtered and regulated before being transmitted through coils to power a receiving coil and charge the battery.

True Wireless Charging
Wireless charging involves transmitting power via microwaves to charge devices without wires. Current wireless charging systems require charging pads and have limited range. The proposed system uses a rectenna that converts microwave energy to DC voltage, allowing for true wireless charging over distances without requiring a charging pad. Potential applications include charging electric vehicles and powering home/office appliances wirelessly. While the initial cost would be high, it could reduce maintenance costs and enable more efficient, convenient wireless power transfer.

WIRELESS POWER TRANSMISSION Project
PROJECT DESCRIPTION
DOWNLOAD
The main objective of this project is to develop a device for wireless power transfer. The concept of wireless power transfer was realized by Nikolas tesla. Wireless power transfer can make a remarkable change in the field of the electrical engineering which eliminates the use conventional copper cables and current carrying wires.
Based on this concept, the project is developed to transfer power within a small range. This project can be used for charging batteries those are physically not possible to be connected electrically such as pace makers (An electronic device that works in place of a defective heart valve) implanted in the body that runs on a battery.
The patient is required to be operated every year to replace the battery. This project is designed to charge a rechargeable battery wirelessly for the purpose. Since charging of the battery is not possible to be demonstrated, we are providing a DC fan that runs through wireless power.
This project is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V, High frequency. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt.
Thus the transfer of power is done by the primary(transmitter) to the secondary that is separated with a considerable distance(say 3cm). Therefore the transfer could be seen as the primary transmits and the secondary receives the power to run load.
Moreover this technique can be used in number of applications, like to charge a mobile phone, iPod, laptop battery, propeller clock wirelessly. And also this kind of charging provides a far lower risk of electrical shock as it would be galvanically isolated.
Wireless power transmission
Wireless power transmission involves transferring electricity without wires between a power source and load. It is necessary because power transmission through wires is unsafe, inefficient, and causes e-waste. Wireless power can be transmitted over both near and far fields using techniques like inductive coupling, resonant inductive coupling, microwave power transmission and laser power transmission. Near field techniques transfer power over short distances efficiently while far field techniques can transfer power over longer distances but require line of sight and have lower efficiency. Wireless power has applications like wireless charging of electric vehicles and has the potential to make electricity transmission completely wireless in the future.
WITRICITY16
Witricity is a technology that wirelessly transfers electrical energy between two objects using magnetic resonance. It was first proposed by Nikola Tesla in 1899, but recent research and development has improved efficiency. Witricity works by generating oscillating magnetic fields between two coils - one powered and one receiving power. While it has advantages like eliminating wires and cables, challenges remain around standardization, costs, and potential for energy theft. Possible applications include charging consumer electronics, electric vehicles, and industrial equipment without plugs.

Wireless transmission is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
Wirelesspowertransmission 141102061911-conversion-gate01
The document discusses wireless charging circuit using inductive coupling. It describes how wireless power transmission works through inductive coupling without wires by using a primary coil in the transmitter and a secondary coil in the receiver. Energy is transferred through mutual induction between the two coils. The transmitter section uses an oscillator circuit to convert DC to high frequency AC which is then transmitted through the coil. In the receiver section, the coil receives power and a rectifier circuit converts it back to DC to charge the load.
Witricity16
Witricity is a technology that wirelessly transfers electrical energy between two objects using magnetic resonance. It was first proposed by Nikola Tesla in 1899, but recent research into resonant inductive coupling has improved efficiency. Witricity works by generating oscillating magnetic fields from a transmitter coil that power a receiver coil within range, eliminating wires and cables. Potential applications include charging consumer electronics, electric vehicles, and industrial equipment without plugs. While promising for the future, witricity also faces challenges from limited range, standardization and potential for energy theft.

HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
