EPC Gen 2 Architecture
EPC or Electronic Product Code is a universal identifier that are encoded on RFID (Radio Frequency Identification) tags to check identities of objects like inventory, assets and people, and track them. The second generation of this technology, as laid down by EPCglobal Tag Data Standard, is called EPC Gen 2.The architecture of EPC Gen 2, RFID network has two main components −Tags or labels − They are affixed on objects so that they can be identified or tracked.Readers or interrogators − They are the intelligent part of the system that tracks the tags.The architecture is shown as below −RFID tags ...
Read MoreElectronic Product Code (EPC)
Electronic Product Code (EPC) is a universal identifier that aims to render a unique identity to every possible physical object of the world. EPCs are mostly encoded on RFID (Radio Frequency Identification) tags that are used to check identities of objects like inventory, assets and people, and track them.EPC is the 96–bit number associated with an RFID tag for identifying a particular tag amongst other tags. It distinguishes two identical products, and also provide the product’s manufacture date, origin or batch number.The EPC structure is laid down by EPCglobal Tag Data Standard, an open standard freely defined by EPCglobal Inc.EPC ...
Read MoreHow does Xiaomi's Foldable Electric Bicycle Work?
We need technology for everything today , be it washing clothes, dishwasher for utensils, or getting medical reports. Our increasing dependency on technology round the clock has inspired the Chinese Technology Giant, Xiaomi to introduce a new product to the market.Yes we are talking about the new talk of the town, the electronic bicycle by Xiaomi, named “Qicycle”How Does it Work?The Qicycle weighs 14.5 kgs and 7kgs.Any other information is yet to be revealed by the Chinese company. But this is a new concept introduced by the company that lures people who love riding eco-friendly bikes, unlike this one the ...
Read MoreWhat went wrong with Samsung's patented Virtual Projection Smartwatch?
Earlier we had simple analog watches, then came the trend of digital watches, then the one with pulse check, heart rate and finally the smart watches. So, if you forgot your phone but have your smart watch, it’s OK. You can still receive all your important calls and messages. Anyways here we are not talking about the smartwatches but watches with some extra smartness. Confused?So let’s put it this way, imagine a watch that would use your hand as an interface. Your hand will be your ultimate watch, cool right? You interact with this interfaces outside the smartwatch. This is ...
Read MoreProject Florence Enabling Gardeners to know what plants "SPEAK"?
Plants are important to make a sense of balance between nature and in people’s lives. Being living organisms, they have a place in the vegetable kingdom that can live on land or in water. Plants and humans are mutually dependent for life and sustainability but are unable to share emotional bonds of each other.However, can you imagine that plants can even speak and feel the emotions of a human being? Yes, it is not just the imagination now. It can be possible. The gardeners can understand the thought of plants and can talk to them scientifically through a great research, ...
Read MoreWhat is a Computer language?
To communicate with the computers, we need some languages. These are computer languages.There are mainly three different languages with the help of which we can develop computer programs. And they are –Machine Level languageAssembly Level Language andHigh Level LanguageMachine Level LanguageComputer can understand only the language of Digital Electronics. Digital Electronics deals with presence and absence of voltages. Within the computer there are two logics can play their role. These logics are –Positive Logic – Here presence of voltage will be denoted by 1 and absence of voltage will be denoted by 0Negative Logic – Here presence of voltage will be ...
Read MoreHow did Sony start and become one of the world leaders in the tech industry?
Sony Corporation is one of Japan's biggest multinational corporations, headquartered in Minato, Tokyo of Japan. It was founded by Akio Morita and Masaru Ibuka on 7th May 1946. It was during the wake of the World War-II. Sony’s first branded product was TR-55 Transistor radio that was launched in 1955, whereas Sony was made to be its official name since January 1958.It was Not-So-EasyEarlier, vacuum tubes were used, whereas, after the invention of transistors, the circuits became shorter and eventually the size of the equipment used got reduced. When TR-55 Transistor radio was launched which was made using a transistor, ...
Read MoreWhat is the Babinet's principle which is the basic for Slot Antenna?
Babinet’s Principle is actually the principle used in optics. According to its definition, “When the field behind a screen with an opening is added to the field of a complementary structure, the sum is equal to the field when there is no screen”The images clearly explain the principle. In all the regions, which are non-collinear with the beam, the above two screens, in figure 1 & 2, produce the same diffraction pattern.Case1Consider a light source and a conducting plane (field) with an aperture before a screen. The light does not pass through the opaque area but passes through the aperture.Case2Consider ...
Read MoreHow does the Microstrip antenna work?
Microstrip antennas are the low-profile antennas. A metal patch mounted on a ground level with a dielectric material in-between constitutes a Microstrip or Patch Antenna. These are very low size antennas having low radiation. The patch antennas are popular for low profile applications at frequencies above 100MHz.Construction and workingThe microstrip consists of a very thin metallic strip placed on a ground plane with a dielectric material in-between. The radiating element and feed lines are placed by the process of photo-etching on the dielectric material. Usually, the patch or microstrip is chosen to be square, circular or rectangular in shape for ...
Read MoreWhat is Flaring and what are the different types of Horn antennas?
To improve the radiation efficiency and directivity of the beam, the waveguide should be provided with an extended aperture so as to make the abrupt discontinuity of the wave into a gradual transformation, so that all the energy in the forward direction gets radiated. This can be termed as Flaring. Flaring is done to provide greater directivity and narrower beam width. The types of horn antennas depend on how they are flared.Sectoral HornThis type of horn antenna, flares out in only in one direction. Flaring in the direction of Electric vector produces the sectorial E-plane horn. As well, flaring in ...
