Flexible OLED display

OLED Displays 👉 OLEDs are thin-film organic semiconductor light-emitting devices. 👉 These consist of a thin film of organic material sandwiched between two electrodes (anode and cathode) as shown. 👉 Organic electroluminescent materials are contingent upon pi-conjugated molecules and are almost insulators. 👉 Light is generated when holes and electrons injected at electrodes recombine.

different types of inheritance supported by Python 👉Single Inheritance – where a derived class acquires the members of a single super class. 👉Multi-level inheritance – a derived class d1 in inherited from base class base1, and d2 are inherited from base2. 👉Hierarchical inheritance – from one base class you can inherit any number of child classes 👉Multiple inheritance – a derived class is inherited from more than one base class.

key features of Python: 👉Python is an interpreted language. That means that, unlike languages like C and its variants, Python does not need to be compiled before it is run. Other interpreted languages include PHP and Ruby. 👉Python is dynamically typed, this means that you don’t need to state the types of variables when you declare them or anything like that. You can do things like x=111 and then x="I'm a string" without error 👉Python is well suited to object orientated programming in that it allows the definition of classes along with composition and inheritance. Python does not have access specifiers (like C++’s public, private) 👉In Python, functions are first-class objects. This means that they can be assigned to variables, returned from other functions and passed into functions. Classes are also first class objects 👉Writing Python code is quick but running it is often slower than compiled languages. Fortunately，Python allows the inclusion of C based extensions so bottlenecks can be optimized away and often are. The numpy package is a good example of this, it’s really quite quick because a lot of the number crunching it does isn’t actually done by Python 👉Python finds use in many spheres – web applications, automation, scientific modelling, big data applications and many more. It’s also often used as “glue” code to get other languages and components to play nice.

This information will be helpful if anyone wants to implement Bar code reader or QR code decoder using a microcontroller. Just like a magnetic card reader..

👉 A pattern of squares forms an alignment pattern that tells the scanner if the code is distorted. 👉 Along two sides of the code, the scanner reading the code superimposes rows of timing squares, which you do not see. 👉 The scanner uses the timing squares to judge how quickly the code is passing through its reading beam. 👉 By calculating the ratio between the light and dark areas in the code, the scanner learns what areas serve to keep everything lined up and which contain data.

Matrix code or QR code 👉 The UPC is good enough if all you need to do is record and read 12 digits. 👉 For a verbose code, you need the capacity of a 2D bar code, also called a matrix code or QR code (for quick response). 👉 The codes are generally about 645.16mmsq (1-inch-square) in size, but can represent 7000 digits or 4000 characters of text—on average, a little less than 700 words. 👉 Using free apps, the codes are read by most smartphones and onscreen by desktops or laptops not equipped with scanners. Not all variety of 2D codes work the same way, though.

👉 If the register’s computer determines that the check digit does not match the algorithm, the scanner beeps to tell the person at the register to re-scan the UPC. 👉 When a scan is successful, the register sends the number to a computer server. 👉 The server checks on the store’s current price for that item and sends that price back to the checkout, where it is added to the customer’s receipt. 👉 For inventory, the server may also update the number of products sold.

👉 In a retail store, when a UPC passes under a laser connected to a register, it does not matter if the right or left side is read first. 👉 The bars on the left side are black with white separating these. 👉 On the right side, it is reversed—white bars separated by black. This lets the register know where the code begins.

👉 The first six numbers encoded in a bar code identify a company that has paid a fee to acquire the rights to a unique manufacturer identification number. 👉 The manufacturer uses the number as the first part of a different 12-digit universal product code (UPC) for each product it makes. 👉 The manufacturer’s six-digit code stays the same for all its products. 👉 The next five digits signify the item number, or product code. 👉 The company’s UPC coordinator assigns an item number, not just to every product but to every model or variation of that product. 👉 The last number in the code is a check digit. Its value must match a number obtained by running the other numbers through an algorithm.

What is the Difference Between Barcode and QR Code?

👉 New-age messaging clients solve these issues actively. 👉 For instance, IceWarp is an emailing platform that has a unique feature called TeamChat, in addition to the usual To, Cc and Bcc fields. 👉 Any message sent across TeamChat is represented in a group chat-like user interface.

2. Smart messaging platform for businesses Businesses more familiarly use either Gmail or Outlook as their main emailing platform. The difficulty often faced by managers and team leaders is keeping track of email interactions, customising recipients, ensuring data privacy and having clear communication with clients.

1. Machine learning (ML)-powered platform for banks 👉 In banks, finding the root cause of faulty transactions often becomes cumbersome because of manual processes. 👉 Automating this can exponentially reduce the time and effort that is invested in root-cause analysis (RCA). 👉 One such platform, delivered by Mindtree on an ML engine developed by TookiTaki, provides an automated alert management and reconciliation solution. 👉 The inbuilt smart reconciliation management system provides quick adjustment recommendations in case of errors and resolutions for exceptions with high accuracy. 👉 The smart alert system detects suspicious activities or bad transactions, and raises caution in real time. 👉 The system increases RCA efficiency up to 50 per cent and reduces false alerts by 40 per cent.

Modern Platforms To Improve And Secure Digital Businesses Security threats, data leakage risks, increasing workloads and many such challenges are evolving, demanding real-time actions from enterprises to prevent massive business losses in terms of money and customers.

Just liked the pictorial explanation of working of transistor..

As shown above the base current I(B) and I(C) combine to form emitter current I(E) which ultimately passes to the emitter terminal.

👉 As shown above a small minute current, I(B) at the base terminal causes the small pink gate to open up which in turn causes the large blue gate to open up. 👉 As this larger gate opens,it allows the large current I(C) to flow from collector to emitter terminal.
