Bed & upholstery vacuum cleaners are the latest innovation in the comparatively mature global vacuum cleaner market. These vacuum cleaners have special features that can deep clean the mattresses and upholstery, thereby eliminating 99% of allergens and dust mites with its improved cyclonic suction, vibrating pads, and UV lights and other features. These are handheld devices with comparatively low power capacity and bagless dust collectors. The market for bed & upholstery vacuum cleaners is currently at the introduction stage; however, their adoption and penetration have been relatively low primarily due to the high penetration of general household vacuum cleaners that are also being used to clean beds or furniture. Further, the availability of dust-resistant mattresses or mattress covers is also resulting in the reduced adoption of such technology.

Backup camera for an automobile is used to get a clear picture of the backup side of the vehicle in order to avoid collisions and accidents which take place due to no visibility while parking the vehicle. Backup camera which are installed on the backup side of the vehicle helps to determine the backup blind spot thus preventing the accidents to occur. The area directly behind vehicles is known as a "killing zone" due to associated accidents and backup camera are used to avoid such kind of accidents. Backup cameras are usually attached to the head unit display of the vehicle and are designed in such a way that the image produced as output is horizontally flipped, thereby producing a mirror image of the object. Various governments across the globe have set regulations for vehicles to be equipped with backup camera as a mandatory component to ensure safety while parking the vehicle, which supports the growth of automotive Backup camera market.

X- Ray security scanner market operates in a consolidated market scenario. Price differentiation is a major market strategy adopted by the players operating in the market. Generally, products of established companies are high-priced in comparison to the local players. Furthermore, companies highly dependent on government tenders or contracts for a major share of their revenues. Also, the maintenance services for these X-ray security scanners generate a significant amount of revenues. There is a huge price difference by tunnel dimension area; for instance, the device deployed for baggage scanner is relatively cheaper than those deployed at vehicle and cargo inspection checkpoints. Terrorism and criminal threats further boost the deployment of the device with variation across various industry verticals. Besides this, the installed mounting base further creates prospects for aftermarket and software upgrade returns. Companies operating in the market are focusing on expanding their footprints into emerging economies of the world. This is due to increasing infrastructural developments in these economies owing to the increasing urban population. Moreover, stringent government regulations towards safety and security concerns are propelling the growth of the market. High risk of terror attacks is another factor bolstering market growth. The government of countries across the globe is concerned about their public safety and hence, mandating proper security checks at public places.

The ultrasonic sensors measure distance through ultrasonic waves. The sensor head releases an ultrasonic wave and accepts the wave reflected back from a target. These sensors measure the distance to the target by calculating the time between emission and reception. The ultrasonic sensors are broadly used in diverse industries, including food & beverage, chemical, medical, automotive, agriculture, process, wastewater management, and more. These sensors have their application in a conveyor belt, smart parking, vehicle detection for car washes, pallet detection with forklifts, diagnosis, liquid level sensing, trash level monitoring, production lines, and others. Some of the prominent benefits of ultrasonic processing technology include process intensification, low power consumption, low cost of processing, operator-friendliness, simple adaptability to specific applications, and environmental safeness makes ultrasonication a technique for the reliable product quality with better outcomes. Owing to an increase in integrating automation into manufacturing and other industries, the use of industry 4.0 is contributing heavily towards the growth of the ultrasonic sensor market. Moreover, the use of sensors in autonomous vehicles and other vehicles with ADAS features to measure the range during parking is giving other opportunities to the automotive industry for growth. On the contrary, the availability of substitute products such as an optical sensor for measuring distance might act as an obstacle in the growth of ultrasonic sensor market.
