Abstract: An advanced chassis structure design offers more battery storage spaces than same-class electric vehicles. The chassis structure provides four battery storage spaces. The significance of these additional storage areas lies in their direct impact on extending the driving range of the vehicle. The chassis structure design further addresses the issue of battery replacement in an electric vehicle chassis. Typically, when an electric vehicle runs out of battery, it takes several minutes or even hours for the battery to be fully recharged. When the battery is broken, the replacement process often involves significant disassembly, which is also time-consuming. With the chassis structure design, the battery is positioned underneath the chassis and fastened within the battery tray and protective battery case. This means that when it comes to battery replacement, the battery can be swapped just by removing a few screws.

Abstract: A blockchain-based room inventory management system includes a property management system (PMS) module and an intermediate server system. The PMS module may be under a hotel's direct control. The intermediate server system communicates with at least one online travel agency (OTA) module and/or at least one booking engine using Ethereum-based smart contracts for confirming and processing a room reservation event. If the room reservation event is confirmed to be a successful transaction, the intermediate server system also updates the successful transaction into the PMS module and a blockchain formed by multiple node servers. The blockchain contains multiple blocks arranged in a chronological order for distinguishing successful transactions of different moments. In this way, each successful transaction is prevented from wrongly preceded by a later successful transaction. And the room inventory management system neutralizes an overbooking issue accordingly.
