Microwave backhaul systems are used for transferring digital data between two distributed points over a radio link. Microwave backhaul technologies are adopted by several mobile operators across the world to transfer huge data traffic over a communication links. Moreover, microwave backhaul systems are growing rapidly as they are capable to deliver large capacity of data with minimized cost.

Contactless payments through a PIN terminal and a chip have become a preferred payment method by the customers. The embedded chip and antenna in the contactless payment system enables customers to pay by waving their cards or mobiles over a reader machine at the POS (point of sale) terminal. In such payment terminals, the transaction speed is twice of the transaction speed of the conventional transaction methods such as cash, credit or debit card purchase. This can be attributed to the fact that any time-consuming pin verification and signature is not required while transacting with the contactless payment terminals. The different stakeholders of the contactless payment terminals market are the chip providers, financial institutions, retailers, and PVC card manufacturers, etc. The contactless payment terminals for vending provide easy integration of merchant services and solutions. It also allows unattended-market operators to accept mobile payments and credit cards including Android Pay and Apple Pay for their varied uses, such as air pumps, car wash, gas stations, kiosks and vending machines.

Freight management systems has risen the growth in many enterprises, by offering faster, more efficient, and flexibility for enterprises. Freight management systems is implemented in transport businesses to optimize the efficiency of commercial freight operations. Freight operation information system offers various features such as vehicle maintenance and repairs, freight tracking system, customer Electronic Data Interchange (EDI) interfacing, comprehensive operational reporting and many others.

Variable Refrigerant Flow (VRF) Systems is a mature heating, ventilation and air conditioning (HVAC) technology which simultaneously heat and cool area through extracting heat from an area which needs cooling and transfer heat to another area. Variable refrigerant flow (VRF) systems are installed with air conditioner inverter that adds a dc inverter which drives the control of compressor that modulates heat or cooling in the area. The compressor unit of variable refrigerant flow (VRF) are installed on the roof of the building, and heat & cool refrigerant are connected through piping connected to condition the building.

Unit testing consumes a larger percentage of share of resources of quality assurance (QA) and in order to simplify the testing efforts, automated testing software is used involving testing to be done with minimum scripts. The automated testing software is used for executing tests, creating reports and comparing results. The automated testing software is extremely useful for regression testing, which is a time consuming and extremely tedious process. Additional benefits offered by automated testing software is environment simulation where testing software can be replicated to create user environment where GUI response is created and analyzed.

Digital logistics provides competitive advantage, efficiency and profitability to the companies by improving supply chain, providing customer effective centric solutions and enhancing efficiency. Digital logistics allow various companies and supply chain logistics applications to closely integrate with labor management systems, core warehouse and transportation systems to enable novel process models and ensure fulfillment excellence. It impacts not only the cost side of the value equation, but also spurs the growth through the ability to deliver customer-focused and personalized logistics, with exceptional customer satisfaction and faster cycle times. The digital logistics industry has opportunities to drive change in both operations and customer engagement including intelligent pallets, omni channel commerce, slot optimization, mobile order management, and predictive maintenance. Companies embracing digital logistics will achieve functional quality in three key areas including distribution, transportation and labor and resource management. Distribution includes real-time warehouse management system (WMS) technology and adoption of improved fulfillment processes. Additionally, various companies have taken advantage of the opportunities to significantly increase employee retention, and work productivity that is available through advanced labor management solutions.

Industrial control systems security presents the assurance of industrial control systems alongside the coordinated programming and equipment used to control and screen the working of industrial hardware and related gadgets. Industrial control systems are utilized as a part of gadgets or apparatus crosswise over different businesses around the world. It controls and deals with the entire thing from different utilities to robot, various power plants, HVAC establishments, industrial control systems and even cell entryways of a jail. There are different outer and interior dangers to industrial control systems, for example, pernicious insiders, programmers, human blunder, and so on. The industrial control systems resource proprietors will buy parts that influence their ICS to secure, non-prominent to runtime creation, and acquire low interest in preparing and upkeep. Accordingly, the IT specialist co-ops are constrained to make security arrangements as a piece of their created parts.

Apache Spark is an open source processing engine used for faster performance, ease of use and sophisticated analytics. Apache Spark can collectively process huge amount of data present in clusters over multiple nodes. Parallel processing framework of Apache Spark enables users to run large scale data analytics applications. It supports in-memory processing boosting the performance of applications based on big data analytics; however, it can also perform disk-based processing when available system memory is unable to store the data sets.

An optical encoder is an electromechanical device which produces electrical output and is proportionate to the angular state of the input shaft. The optical encoder operates on the principle of optics which converts angular displacementor mechanical rotary motion of an input shaft into a digital signal. A light source from an infra-red or LED is passed through a rotating high-resolution code disk or encoded disk which contains a binary code or grey code. Photo sensors, which could be a phototransistor, photovoltaic cell, or silicon photodiode on the other side of the disc scans the rotating encoded disk and generates the output electric signal. The output signal from the photo sensors is a series of voltage pulses since the light from infra-red or LED source is interrupted by opaque areas of the encoder disc. Incremental encoders and absolute encoders are two basic types of optical encoders. Incremental encoder also known as relative rotary encoder produces the square wave pulses output signal. On the other hand, absolute encoders produce the unique output code for every rotating position of the input shaft and are more complex than incremental encoders. Optical encoders are usually used to monitor and control motion parameters including position, distance, direction, rate, and speed

Laser scanner is a device which releases a controlled deflection of laser beam and can be used for various purposes including scanning. Laser scanning is a technology in which a combination of controlled steering of laser beams and distance measurements is involved. Laser scanners can capture and measure the geometry of objects and the environment by using laser. They are applied in various industries for inspection and quality control and virtual simulation, among others. Laser scanners are more specifically referred to as 3-D laser scanners.
