Two basic concepts of this technology called the bottom-up concept and the top-down concept are also explained in detail. After going through this technology, you could check out further informative posts by clicking on the link – More on Nanotechnology

5. Working of Facial Recognition System

This topic mainly deals with the use of softwares combined with electronics to detect a person from a huge crowd. This is mainly used by law enforcement agencies, and also in ATM’s. The article mainly deals with the different methods used to recognize a person with almost 99% accuracy. A detailed figure showing the different nodal points that are used by the software to compare the original photo with the video captured one is shown in the article. The different comparison procedures like vector template, local feature analysis, and surface texture analysis is also explained in the post. The advantages, disadvantages, and applications are also given.

6. Working of Electronic Ink (E-ink) Technology

The method of using a type of digital ink to write on screens is used in this technology. Three components are used for manufacturing this ink. They include millions of microcapsules, the ink substance present in an oily form which fills the microcapsules, and the negative charged pigmented chips or balls which float inside the microcapsules. This article describes in detail about the exact working of this material, and about the type of screen that is used for this purpose. A figure showing the working and the uses of this technology can also be seen in the link above.

7. Working of Fingerprint Scanner

A finger printer scanner is used by most companies to restrict outsiders from coming in. Even laptops have fingerprint scanners to allow the owner to restrict others from using his confidential data, or websites, and so on. This article gives a detailed study of the use of such devices, the way it works, how fingerprint is analyzed, and so on. The two types of fingerprint scanner – optical scanner and capacitance scanner are also explained. The working is explained with a well described block diagram, along with the devices’ advantages and disadvantages.

8. Photonic Integrated Circuit (PIC)

Photonic Integrated Circuit (also known as PIC), is a complex integrated circuit which incorporates a lot of optical devices to form a single photonic circuit. The article describes the difference between a PIC and the conventional Electronic Integrated Circuits. A figure of a GaAs-InP Photonic integrated circuit is also explained in detail. Two basic photonic integration methods like Hybrid Photonic Integration and Monolithic Photonic Integration are also explained in this article. You can also look at the advantages and applications of PIC from the link above.

9. Working of 3-D TV

Nowadays, most movies are made in 3-D and the special effects that are brought into the movies make it cooler. 3-D Technology is explained in detail, including the type of glasses that are used to watch such movies, and how to make them by yourself. The basics of 3-D are explained along with its difference with 2-D. Stereoscopic TV and Autostereoscopic TV is also explained in this post. The future development that is going to happen to this technology is also given in this article.

10. RedTacton Technology

RedTacton Technology is a concept that refers to the transmission of signals at very high speeds through the human body. Just like the Bluetooth Technology, this concept is also known to be wireless in nature. The transmitter and receiver used in RedTacton and is explained with the help of a figure. Some interesting features of the technology like touch, media, and broadband are also explained with an image. Its applications and comparison with other wireless technologies like w-fi, RFID, Bluetooth, and W-CDMA are also explained.

11. Smart Antennas

Smart Antennas are adaptive array antennas that are designed for one main purpose – to maintain the high efficiency in digital wireless communication systems. The objective is obtained by taking the advantage of the diversity effect at the transceiver of the wireless system that is the source and the destination. This concept has already been adapted in some wireless communication systems as special antenna arrays are used with signal processing algorithms which can easily locate and track the different wireless targets such as mobiles. The two functions of smart antennas namely estimation of direction of arrival, and beamforming method is also explained in detail. Adaptive array antennas and phased array antennas are also explained in the article. The difference between this antenna and the conventional one is also given along with its advantages and disadvantages.

12. Working of Standing Wave Ratio (SWR) Meters

This device is used to measure the standing wave ratio in a communication line. The meter will denote the exact mismatch between the transmission line and the load, thus helping to know the degree of effectiveness of the impedance matching efforts. The article explains in detail about the topic with a neat figure. The SWR bridge circuit and the problems with that could occur with he use of SWR meter is also explained in the article.

13. 3-D Handwriting Technology – Make Functional Electronic Circuits on Paper Using Silver Ink Pen

The basic method for making electronic circuits is by designing a PCB or a Vera board for the purpose. This technology called 3-D handwriting simplifies the whole process by just drawing the layout on a paper with a silver coloured liquid metal ink. An image showing an illustration of the technology is given in the original post. The pen used for drawing the circuit is made of an ink with conductive property.

14. Faster Data Transfer with Point and Paste Technology

All types of communication between business people and also friends are now made through e-mails and social networking sites. But, a greater method to send data would be through the so-called “Point and Paste Technology”. The method uses a temporary storage for the data while you point out at a certain data on your device and just touch another device where it is to be stored.

15. Lenticular Lenses

This i s a completely new technology through which you get to see 3D movies with the same effect, and that too without the use of glasses. The basic idea used behind this technology is called lenticular viewing. Tiny cylindrical plastic lenses are placed on the screen of an LCD tv. This sheet gives all the 3-D effects needed.
