Why Touch Screens Only Respond to Fingers: The Science Behind the Sensitivity

  I. Introduction Touch screen technology enables direct interaction with devices through touch. Using either capacitive or resistive methods, these screens detect user input, translating it into commands. Widely used in smartphones, tablets, and kiosks, touch screens offer intuitive navigation, eliminating the need for physical buttons and enhancing user experience across various applications. Understanding how touch screens work is crucial for users and developers alike. It enhances user experience by ensuring effective interaction, informs choices in device selection, and guides troubleshooting. For developers, knowledge of touch technology is vital for creating intuitive applications and improving interface design, ultimately leading to greater user satisfaction. This blog aims to explore why touch screens predominantly respond to fingers, delving into the science behind touch sensitivity. By examining the principles of capacitive and resistive technology, we will uncover the

Difference between Barcode, QR code and RFID

Difference between Barcode, QR code and RFID    What Is A Barcode? Norman Joseph Woodland and Bernard Silver  was the first to invent barcode, initially it was based on the dots and dashes of Morse Code. In the 1960s American Railroads started to use barcodes to identify trains, cars etc. It wasn’t until the 1970’s that The barcodes became commercially successful in 1970 and thereafter it has been taken up by supermarkets as a way to quick matching of items at the checkout point which is now universally used today. A barcode is nothing but a series of black and white lines, each representing a number and obviously each bar code is of different patterns. Once a product arrives at a store, the barcode is coded with a price for that particular product and when a purchase is made at the counter, a laser reads and decodes the code and the price is automatically added to the purchase receipt. This is just one simplest example of how barcodes is used popularly and it is the one we are famil

steering-angle sensor || How does the steering-angle sensor work?

  What is steering-angle sensor? The steering-angle sensor is based on Giant Magnetoresistance technology (GMR element) and provides an absolute steering-angle value over the complete steering-angle range (multi-turn sensor). A unique feature of this steering-angle sensor is the output of the correct angle within the measurement range directly after ignition-on. Movement of the steering wheel or other measures for initialization of the sensor (True Power-on) is not required even after disconnection and re-establishment of the power supply. No standby current is necessary. The steering angle and steering-angle velocity is made available via CAN interface. Sensor-internal plausibility tests and special self-diagnostic functions allow the use of this sensor in safety systems. The sensor concept also allows the integration of a second microprocessor for safety-related applications.   Why do we need to Measure Steering Angle? The angle of the steering on its own can be used to deter

Total Quality Management (TQM)

 Comprehensive Quality Management (TQM) TQM is a collection of management processes across the organization, intended to ensure that the organization consistently meets or exceeds customer requirements. TQM places a strong focus on process balance and control as a way forward better. Before learning more about TQM, it may help to review very quickly types of quality management in an organization. These are briefly described at the top of the Quality Management article. 7 Essential Principles of Comprehensive Management Total Quality Management (TQM) is the approach that organizations use to improve their internal processes and increase customer satisfaction. When it's used properly, it can lead to a reduction in related costs corrective or preventative adjustments and overall performance. However, TQM is not something that happens overnight. Although there is a number of software solutions that will help organizations get started faster quality management system, there

What is battery management system (BMS) in electric vehicles?

  Introduction: The growth of urban sprawl and pollution in big cities is raising public awareness to a more stable mobility solution, which means more efficient use of energy, reduction in pollutants and continued driving development of electric vehicles (EVs). With a view to achieving 100 million EVs on international roads by 2020 (IEA and EVI, 2013), the automotive industry has set the bar high for the public bookings about electromobility so as the battery technology is in high demand. Next to the development of chemical and technological advances in mobile battery technology, battery management system (BMS) is the main protector of the EVs battery system, tasked with verification reliable and safe operation of connected battery cells to deliver high currents at high voltage (HV) levels (the term “battery management system” has no universal meaning and is generally   understood to refer to any system responsible for monitoring, control, and protection of battery cells, either indiv

How The Accelerator Works in Car?

Is speeding your car the only thing you know about how the accelerator works in your car? Read the article for more interesting information. Many people have been wondering how the accelerator works in a car. To understand this, we must learn what an accelerator is. The car accelerator can also be known as a gas pedal located on the bottom right of the car. It is called an accelerator because it controls the speed of the car. The deeper we press the accelerator of a car, the faster the car produces faster. So, push it slowly, or you will end up at a sudden speed that could lead to fatal accidents. Typically, an accelerator is a pedal we push to control the speed of our vehicles. How does the accelerator works? It is easy to learn how the accelerator works in a car. As mentioned earlier in this article, an accelerator speeds up a car based on its depth. To illustrate this, let's take a look at the accelerators of most fuel-efficient cars. When we press the pedal, it opens the th
