When usedas an air-assisted mattress, the HoverTech Air Supply inflates the HoverSling to cushion and cradle the patient, while air simultaneously escapes from the holes on the underside, reducing the force needed to move the patient by 80-90%. In this capacity, the HoverSling can be used to assist caregivers with lateral patient transfers, positioning (including boosting and turning), and proning. The HoverSling can also be used uninflated for vertical patient lifts, turning, and proning with a loop style hanger bar.INDICATIONS• Patients unable to assist in their own lateral or vertical transfer.• Patients whose weight or girth poses a potential health risk for the caregivers responsible for repositioning, vertically transferring or laterally transferring said patients.CONTRAINDICATIONS• Patients who are experiencing thoracic, cervical or lumbar fractures that are deemed unstable should not use the HoverSling unless a clinical decision has been made by your facility.INTENDED CARE SETTINGS• Hospitals, long term or extended care facilitiesPRECAUTIONS – FOR USE AS AN AIR-ASSISTED TRANSFER MATTRESS• Caregivers must verify that all brakes have been engaged prior to transfer. • Use a minimum of two caregivers during air-assisted lateral patient transfers.• For in-bed air-assisted positioning tasks, more than one caregiver may need to be used. Side rails must be raised with one caregiver. • For air-assisted proning, see HoverTech’s video on .• Never leave patient unattended on an inflated HoverSling.• Only use the HoverSling for its intended purpose as described in this manual. • Only use attachments and/or accessories that are authorized by HoverTech International.• When transferring to a low air loss bed, set the bed mattress air flow to the highest level for a firm transfer surface.• Never attempt to move a patient laterally on an uninflated HoverSling.• Ensure patient is centered on HoverSling before inflating.PRECAUTIONS - AIR SUPPLY• Route the power cord in a manner to ensure freedom from hazard. Avoid blocking the air intakes of the air supply.• When using the HoverSling in the MRI environment, a 25 ft. specialty MRI hose is required (available for purchase).• CAUTION: Avoid electric shock. Do not open air supply.• Reference product specific user manuals for operating instructions.PRECAUTIONS – FOR USE AS A SLING• For lateral patient transfers, more than one caregiver may need to be used. • For in-bed positioning tasks, more than one caregiver may need to be used. Side rails must be raised with one caregiver.• For proning, see HoverTech’s training video on .• The HoverSling should only be used by trained personnel.• Only use attachments and/or accessories that are authorized by HoverTech International.• Before use, a risk assessment must be carried out to ensure that the correct size HoverSling is being used for the patient.• A clinical assessment should be carried out by a qualified nurse and therapist before lifting patients with the HoverSling.• Do not use the HoverSling Split-Leg lateral transfer handles to lift.Excessive force on the lateral transfer handles can cause the HoverSling to tear.• Make sure the HoverSling is not attached to any object other than the loop style hanger bar.• When connecting to loop style hanger bar, ensure shoulder strap loop colors match on the patient’s left and right side and leg strap loop colors match on the patient’s left and right side.• Once the sling support straps are fully extended, make sure they are properly connected to the hanger bar before the patient is lifted.• For seated lifts, make sure the patient is sitting securely in the HoverSling® before transferring or lifting.• Never lift a patient higher than is necessary to complete the lift/transfer.• Never leave the patient unattended while using the HoverSling.• Use the HoverSling according to both the lift and HoverSling instructions.• If the weight limit differs among the patient lift, hanger bar, and HoverSling, then the lowest weight limit applies.If there is any indication of damage, remove the HoverSling from service and discard.Side rails must be raised with one caregiverIn the OR: To prevent the patient from slipping, always deflate theHoverSling and secure the patient and HoverSling to the OR table prior tomoving the table into an angled position.DECLARATION OF CONFORMITYThis product conforms to the requirements of Medical Devices Regulation (2017/745).Further, this product conforms to the requirements of: ISO 10535Part Identification – HoverSling® Split-Leg Air Supply Hose Inlets (2)Strap Pockets (6)Product Specifications/Required AccessoriesHOVERSLING® SPLIT-LEGMaterial:Top: Polyester knitBottom: Nylon TwillConstruction:SewnWidth:34" (86 cm)Length:70" (178 cm)Model #: HMSLING-34-B* – 34" W x 70" L (10 per box)LIMIT 700 LBS/ 318 KG*Breathable modelREQUIRED ACCESSORY FOR USEAS A TRANSFER MATTRESS:Model #: HTAIR1200 (North American Version) – 120V~, 60Hz, 10AModel #: HTAIR2300 (European Version) – 230V~, 50 Hz, 6AModel #: HTAIR1000 (Japanese Version) – 100V~, 50/60 Hz, 12.5AModel #: HTAIR2356 (Korean Version) – 230V~, 50/60 Hz, 6AModel #: AIR200G (800 W) – 120V~, 60Hz, 10AModel #: AIR400G (1100 W) – 120V~, 60Hz, 10AREQUIRED ACCESSORY FOR USE AS A SLING:Any patient lift with 2, 3, or 4-point loop style hanger bars intended foruse with:• Mobile hoists with sling seats• Hoist trolleys• Stationary hoists fixed to the wall/walls, floor and/or ceiling• Stationary free-standing hoistsHoverSling® Split-Leg Instructions for Use as a SlingINSTRUCTIONS FOR USE – PATIENT IN BEDNote: HoverSling Split-Leg has six (6) sling support straps that need to be connected.1.O ption 1underneath patient using log-rolling technique with the apex of the sling’s horseshoe at the coccyx of the patient.

nb iot原理与测试

nb iot原理与测试NB-IoT（Narrowband Internet of Things）是一种低功耗、宽覆盖、长连接的物联网通信技术。

它基于现有的移动通信网络，使用窄带调制方式进行通信，具有低延迟、低功耗、高可靠性等优点。

NB-IoT适用于物联网设备传输少量数据、低频率通信的场景，如智能照明、智能家居、智能电表等。

NB-IoT的原理是通过在现有的移动通信网络中引入新的物理层、MAC（Media Access Control）层和RRC（Radio Resource Control）层的改进，使得网络可以支持物联网设备的低功耗连接和宽覆盖。

具体来说，NB-IoT利用带宽较窄的子载波进行通信，通过采用窄带调制的方式来传输数据，使得设备在通信过程中耗能较低。

同时，NB-IoT还引入了功率与覆盖的优化技术，可以在室内和较远的距离内提供稳定的通信连接。

为了测试NB-IoT的性能，通常需要进行以下几个方面的测试：1. 信号覆盖测试：测试NB-IoT网络在不同地点的覆盖范围和信号强度，评估网络的可靠性和稳定性。

2. 传输速率测试：测量NB-IoT网络在不同情况下的数据传输速率，包括上传和下载速率，以验证网络的传输性能。

3. 耗电量测试：测试NB-IoT设备在不同工作负载下的耗电量，评估设备的电池寿命和续航能力。

4. 抗干扰性测试：在有干扰信号的环境下测试NB-IoT网络的稳定性和抗干扰能力。

5. 安全性测试：测试NB-IoT网络的安全机制和数据加密算法，评估网络的安全性和防护能力。

通过以上测试，可以全面评估NB-IoT网络的性能和可靠性，为实际应用和部署提供参考依据。

什么是物联网洗衣机

编辑词条物联网洗衣机目录[隐藏]一、什么是物联网二、什么是物联网洗衣机三、从物联网到物联网洗衣机的推出四、物联网洗衣机的功能五、物联网洗衣机的推广普及六、物联网洗衣机行业发展可能面临的问题[编辑本段]一、什么是物联网物联网（The Internet of things）的定义是：通过射频识别（RFID）、红外感应器、全球定位系统、激光扫描器等信息传感设备，按约定的协议，把任何物品与互联网连接起来，进行信息交换和通讯，以实现智能化识别、定位、跟踪、监控和管理的一种网络。

物联网实质就是“物物相连的互联网”。

这有两层意思：第一，物联网的核心和基础仍然是互联网，是在互联网基础上的延伸和扩展的网络；第二，其用户端延伸和扩展到了任何物品与物品之间，进行信息交换和通讯。

[编辑本段]二、什么是物联网洗衣机所谓的物联网洗衣机，就是用射频自动识别技术，使得洗衣机和物体之间能够识别的洗衣机。

从使用上看，物联网洗衣机能通过电脑、移动终端等传感设备，实现洗衣机的远程控制、同时还能实时查询洗衣机的工作状态，通过控制系统返回洗衣机的相关信息。

从技术上看，它是各类传感器和现有的“互联网”相互衔接的一种新技术，是对“互联网”技术的延伸。

现在，物联网已开始不断地改变着我们的生活方式和消费习惯。

[编辑本段]三、从物联网到物联网洗衣机的推出从1999年开始，有关物联网的概念开始逐渐进入人们的视野。

它被认为是继互联网之后，下一个万亿级的信息技术。

近10余年间，世界各国都在加紧研究互联网技术。

物联网的发展共分为四个阶段：第一个阶段是大型机、主机的联网；第二个阶段是台式机、笔记本与互联网相联；第三个阶段是手机等一些移动设备的互联；第四阶段是嵌入式互联网兴起阶段，更多与人们日常生活紧密相关的应用设备，包括洗衣机、冰箱、电视、微波炉等都将加入互联互通的行列，最终形成全球统一的“物联网”。

全球率先上市的物联网洗衣机是由小天鹅于2009年在美国推出的。

安静高效护健康米家互联网直驱洗烘一体机评测作者：徐雨辰来源：《家用电器》2021年第02期设计上的“减法”与功能上的“加法”米家互联网直驱洗烘一体机延续了米家产品一贯的简约设计，极简的线条和结构搭配凸显气质的灰系色调，可以百搭各种家居风格。

机身的整体尺寸为595mm*680mm*850mm（宽深高），钛金灰色箱体抗腐蚀、不易变形生锈；两侧起伏的压型设计能有效减小运转时所产生的震动，降低噪音；背面钢板选材精良、线管布局井然有序。

外观直线与弧角线条过渡完美，方寸之间尽显用心雕琢。

该机正面的控制面板分区精简。

左侧是洗涤剂投放盒，可分别倒入主洗洗涤剂、预洗洗涤剂和柔顺剂；右侧是本机的特色功能点，分别是“DD直驱电机”、“银离子除菌”和“WiFi智能互联”；中间是一块感触非常灵敏的全触摸式显示屏。

该屏囊括了多达16种的洗烘程序，同时还有水温、转速、漂洗、预约等多种辅助操作，用户在使用时可根据不同的需求自由组合选择，满足多重复杂的洗涤需求。

下方舱门的超大门圈设计，让开关门更方便，取放衣物更轻松；清晰透明的玻璃视窗能让用户对衣物洗涤的全部过程尽收眼底；专业抗菌防霉门封能有效防止滋生细菌，严防衣物二次污染，底部的“V型”凹槽搭配排水孔可将残水排净。

10KG大容量的内筒能够轻松洗涤全家人的衣物，哪怕是像窗帘、被罩、床单这样的大件衣物也能轻松搞定；门封上别致的照明灯非常实用，可在光线不足的情况下清晰照亮内筒运转状态，以便用户查看；在洗烘一体机运行过程中，双路喷淋可分别冲洗门窗和门封，清除泡沫及残留；如果想要中途添衣也很方便，只需按下暂停键，待解锁声出现即可开门添衣，丝毫不会影响任何洗衣流程。

前文我们也提到，米家互联网直驱洗烘一体机机身特别标注了三大特色功能点，具体来说分别是：DD直驱电机：作为第五代直驱电机，它可从源头降噪，低振耐用，动力强劲，控制上也更加精准，使运行更安静。

银离子除菌：特有的银离子除菌设计，可在洗衣过程中不断释放银离子，除菌率高达99.9%。
