Similar to a mechanical water meter, a smart water meter is connected to a data logger that continuously monitors a building's or home's water consumption. However, whereas traditional water meters only measure total consumption, smart water meters are Internet-capable devices that record when and how much water is being used, providing real-time information that enables companies and individual consumers to understand and monitor their water consumption. Smart water meters help water utilities, in particular, to manage their water networks more efficiently and provide better customer service, chiefly by allowing them to accurately determine water consumption at peak periods. For instance, washing machines create pulses when in use, which are logged by a data logger in a predefined frequency. User-defined parameters, such as flow rate, time, and volume, disaggregate the information provided by these pulses and assign them to different water-use "events." These events are then retrieved by the smart water meter, so that water consumption or wastage can be measured and controlled. Smart water meter information can be represented as exhibited below:

Generators are backup devices designed to provide temporary AC power by using the supplied fuel, which can be either diesel or gas. Generators, depending on their portability, are segmented into two broad categories: Portable Stationary Portable generators are the best solutions to provide AC power for standby non-hardwired applications. Low-end models support only a few basic home appliances. However, there are high-end portable generators that can provide backup AC power to an entire house. Apart from residential use, portable generators are widely used in commercial buildings as well as industrial and infrastructure sites. In short, they can be utilized in all places where grid is unavailable.

An EV traction motor converts electrical energy into motion that propels an EV. Traction motors form a major component in EVs such as cars, two-wheelers, light industrial/commercial vehicles, military vehicles, buses, and others. These motors are the primary determinant of the performance and affordability of an EV.

提出了一种新型阵列式波浪能发电装置,叙述了该装置的工作原理。对装置的波浪能采集部分建立了仿真分析模型,并基于AQWA对模型进行了参数设置及有限元网格划分。以仿真模型为基础,分析了单个浮子在不同尺寸及不同吃水下的频域响应RAO值,同时对整个浮子阵列在不同波向下的时域响应特点进行了分析。发现在浮子吃水深度为1.2至1.4m,浮子直径为2.8m时,单个浮子的RAO值较大,而波浪波向为22.5°时,浮子阵列中各浮子间振幅差较小,且浮子阵列的平均振幅较大,有利于更加稳定高效地采集波浪能。
