Bungee jumping is an extreme adventure sport. In this, a jumper does a free fall from a fixed tall structure like a cliff, bridge, or crane, as well as from a stationary hot-air balloon or helicopter, with the help of a harness and a rubber cord (commonly known as a bungee cord) attached to the body. The jumper bounces back to some extent when the bungee cord rebounds its maximum stretch, and continues to fly up and down until all the kinetic energy is dissipated.

The rise in awareness of infant care in developing countries like India and China is increasing the demand for baby care products. Urbanization in these regions is another factor. Developed countries like the US continue to dominate the market in terms of revenue. The increase in the number of working women has led to mothers being ready to pay for premium products. They purchase these products in bulk to reduce the price.

Luggage and related luggage products are increasingly moving away from having only utilitarian value to functioning as fashion accessories. Luggage products have been gaining consumer interest with the growing popularity of outdoor sports and adventure travel, apart from a rise in the global travel industry. The market is expected to witness growing demand for durable luggage products that are also compact and lightweight. To cater to this demand, manufacturers are using materials like nylon, polyester, polycarbonates, faux leather, and microfibers.

泛半导体行业重回景气周期，带动上游设备需求量增加。上游设备被美日荷垄断，市场集中度高。

新能源汽车的兴起带来产业链上游关键零部件的更新浪潮，轮毂电机作为典型的分布式驱动系统，具有广阔市场前景。目前国内绝大多数新能源汽车采用集中式驱动系统，结构与传统汽车相似，可靠性好但传动效率较低。与集中式驱动系统相比，分布式驱动系统具有传动链短、经济性好、车身内部空间利用效率高等特点。

重卡属于生产资料，随着公路运输高速化、下游物流客户从个人向组织化、集约化物流公司集中及环保趋严，高性能环保重卡对客户的吸引力大增。对标国外，美国 8 级卡车平均排量早已接近 13 升，500 马力以上卡车已成为主流，而我国国内重卡目前发动机平均排量仍不到 10L，平均功率大约 350 马力，售价仅越相当于国外高端重卡的 22%-33%。

Outdoor flooring is an element that provides outdoor areas with attractive and durable floor covering. There are a number of flooring options that can provide an elegant design to the outdoor area. The different types of outdoor flooring are as follows: Outdoor floor tiles: A wide range of tile types are available that are formulated specifically for outdoor application. Many tiles feature grit pattern and texture to make the surface anti-slippery. The frost resistant and unglazed tiles are highly popular in this segment.

17 年是新能源客车调整年，预计 18 年新能源客车在公交客车电动化进一步深化及新能源座位客车渗透率提升下，新能源客车销量有望同比增长 15%左右，在补贴持续退坡下，新能源客车市场份额将加速向龙头集中，弱势客车企业将逐步退出市场。看好新能源客车产业链，相关公司有望受益。建议关注新能源客车产业链标的：整车：金龙汽车、中通客车；电池：宁德时代、国轩高科、亿纬锂能等。

新能源汽车驱动电机主要有直流电机、交流异步电机、永磁同步电机、开关磁阻电机。其中开关磁阻电机由于噪音、振动等未广泛应用；永磁同步电机和交流异步电机性能出色，是目前新能源汽车的唯二选择，但前者具有更大调速范围，功率密度、扭矩密度具有较大优势，可做到更小的体积和自重，成为主流选择。

RFID technology uses the electromagnetic signature that accompanies the radio frequency in a specific spectrum to communicate information, which is mostly one way. This process is carried out by RFID microchip (RFID tag), RFID reader, and RFID middleware components.
