Fuse holders are electronic devices that are used for containing, mounting, and protecting fuses. Fuse holders basically come in two types: open and fully enclosed. Open fuse holders are fuse blocks, clips, plug-in caps, and socket varieties. Fully enclosed fuse holders use a fuse carrier, which is inserted into the holder or some other part to fully enclose the fuse.

Air filters are used to filter the incoming air by trapping particulates such as dust, pollen, mold, smoke, debris, and bacteria from the air. These filters are used in a wide range of applications wherein air quality is crucial. In a building’s HVAC system, air filters are a tangible way to improve IAQ, energy efficiency, and performance of the HVAC system. Air filters work as an defensive component by capturing pollutants generated within a building as well as pollutants from the air drawn into a building through the HVAC system.

Growing digitization of learning followed in educational settings has given way to deploying solutions that complement the learning process. The new model of connected teaching customizes learning by linking students and teachers to a network of professional resources, content, and systems. Moreover, online courses and open resources and technologies are effective in terms of cost and time and ensure maximum productivity. In addition to embracing digital content, institutions are using education technology for various activities, such as tracking grades, attendance, scores, and demographics, to enrich the quality of curriculum and the teaching process. While technologies such as mobile and cloud technology have improved student's know-how, solutions like big data analytics and learning management system (LMS) have made the process of imparting education more coherent.

The global geospatial industry is classified into segments such as traditional GIS, global positioning system (GPS), photogrammetry and remote sensing, and geocapable engineering. The traditional GIS segment is the largest revenue contributor to the global geospatial industry. We have considered traditional GIS in this report for revenue generation. Increased demand for GIS in the national government, transportation, natural resources, utilities, military/law enforcement, and communication and telecom sectors will contribute to the growth of the global GIS market.

A kegerator, also known as a beverage dispenser, is a refrigerator that can store and dispense kegs of draft beer and other beverages. The word kegerator is originated by combining two words: keg and refrigerator. A keg is kept in a refrigerated environment and CO2 is used to pressurize and dispense the keg. Therefore, the content kept in the keg remains carbonated and fresh for an extended period of time, generally a couple of months.

Adaptive brake lights alert drivers of the emergency brake being activated in the vehicle in front of them. The flashing of the brake lights indicates to the car behind that the emergency brakes are being activated. The brake lights are automatically activated to flash several times with different illuminating levels when the vehicle undergoes an emergency brake while traveling at a speed of over 60 km/h. The intensity of the brake lights could be enhanced through the activation of additional lights along with the car’s existing brake lights upon emergency braking. The signal can either be given through flashing of brake and hazard lights or through high-intensity brake lights (intensity higher than that during normal braking), along with the activation of hazard lights.

Active seat belt systems consist of electrically driven active retractors, pretensioners,and buckle lifters. The pretensioner tightens or loosens the belt slack as per the road situation. During a hazardous road traffic situation, such as a sudden application of the
brakes or the vehicle skidding, the pretensioner in the active seat belt system tightens the seat belt to fix the driver and the occupants in a safe seating position. The pretensioner thus also alerts the driver to the potentially hazardous situation. At the
same time if the driver actively maneuvers the vehicle avoiding the road accident, the active belt system then loosens the webbing to offer comfort to the driver. The same is done for the other occupants of the car (cars where the rear seat are also equipped with active seat belt system).

Active aerodynamics employs self-adjusting spoilers, open and shut vents, and inmotion height adjustments to keep vehicle firmly ground on the road.The automotive aerodynamics basically deal with two prominent forces that interact with vehicle, downforce and drag. The proper management of these two forces is crucial for the performance of a vehicle.
