What is an Video conferencing End-points?

By Sally
  What is an Endpoint? An endpoint in the realm of videoconferencing is a term that many on the user side—like doctors, nurses, patients, and office staff—may encounter, though they might not be fully aware of all the technological elements involved in their virtual meetings. Essentially, an endpoint is a networking node that can initiate and participate in a videoconferencing call with another similar node. On a more practical level, it includes the equipment like the CODEC, camera, and display used during a video call. The CODEC stands for coder-decoder. It's the backstage tech wizard that processes the audiovisual content during a videoconferencing session. As the heart of the endpoint, the CODEC captures video from the camera and routes it to the screen, as well as handling audio and video from other devices, communicating with the core network infrastructure, or establishing a connection with other endpoints. CODECs vary in size and design, ranging from large, computer-like de...

 What’s all the fuss about Jetboards? What is a jetboard? A jetboard is a motorized surfboard, where the rider controls the speed using a hand-held remote control and uses weight transfer to manoeuvre the board. From the introduction of jetboards a new water sport has emerged known as jetboarding. Why get a jetboard? With an exceptional growth over the past years, jetboards have gained popularity and momentum worldwide, and is often referred to as “the next big thing in water sports”. By providing an enjoyable and exciting experience on water suitable for all riders, jetboarding is an innovative addition to traditional water sports. The motorized surfboards eliminate the struggles of conventional surfboarding as they can be ridden without wind and waves. There is also no need for tedious paddling as the boards can ride by the touch of a button. Compared to traditional surfing, jetboarding can quickly be learnt and allows the rider to master the sport in no time. This further makes ...

新能源汽车充电桩的种类及特点

By Sally
新能源汽车充电桩的种类及特点 一、充电桩的种类 1、按充电方式 （1）交流充电桩 交流充电桩俗称“慢充”，固定安装在电动汽车外、与交流电网连接，为电动汽车车载充电机提供交流电源的供电装置。交流充电桩只提供电力输出，没有充电功能，需连接车载充电机为电动汽车充电。相当于只是起了一个控制电源的作用。 （2）直流充电桩 直流充电桩俗称“快充”，它是固定安装在电动汽车外，与交流电网连接，可以为非车载电动汽车动力电池提供直流电源的供电装置。可直接输出直流电，为电动汽车的电池充电，输出的电压和电流可调范围大，可提供足够的功率，实现电动汽车快速充电。直流充电桩充电速度较快，故一般安装在高速公路旁的充电站。 （3）交直流一体式充电桩 快速充电桩设备采用交直流一体的结构。既可实现直流充电，也可以交流充电。白天充电业务多的时候，使用直流方式进行快速充电，当夜间充电站用户少时可用交流充电进行慢充操作。采用触摸和键盘互为备份的操控，触摸屏和键盘采用防雨、防尘的设计；具备紧急停机的急停开关；具备充电接头安放槽，安放槽可防水。 2、按安装地点 （1）公共充电桩。建设在公共停车场结合用车泊位，为社会车辆提供充电服务的充电桩 （2）专用充电桩。建设单位自有停车场，为单位内部人员使用的充电桩。 （3）自用充电桩。建设在个人自有车库，为私人用户提供充电的充电桩。以上是按照不同方式介绍不同种类的充电桩，下面我们主要介绍根据充电方式划分的充电桩特点。 二、充电桩的特点 1、交流充电桩特点 （1）交流充电桩结构简单、桩体小，输入侧只需要从电网接入，输出也是交流，成本较低，安装更方便。适合安装在小区及单位停车场自己使用。 （2）交流充电桩的功率一般都比较小，充电速度比较慢，一辆电动汽车完全放电后，通过交流充电桩充电通常需要8小时左右才能充满。 （3）防护功能。交流充电桩应遵守IP54（在室外），并配置有防雨、防晒装置，保护充电桩不受雨水侵袭。充电桩电桩外壳门装防盗锁，固定交流充电桩的螺栓必须在打开外壳门后方能安装或拆卸。充电桩铁质外壳和暴露在外的铁质支架、零件采取双层防锈措施，非铁质的金属外壳具有防氧化保护膜或进行防氧化处理； 2、直流充电桩特点 （1）直流充电桩相对交流充电桩，体型比较大一些，因为直流充电桩内部有一定数量的电源模块，功率越高，模块数量越多，桩体越大。适合安装在公共区域。 （2）直流充电桩可对电...
