Steering wheel: The steering wheel of many cars is designed with a female hand, so that female drivers are more comfortable in the continuous driving process. Seats: Many car seats are developed by female designers, paying attention to detail and ergonomics, making the whole seat more in line with the human body curve, improving comfort and support.
In addition, some parts are completely bought back, without design, these parts are generallyStandard parts (referred to as standard parts), such as nuts, screws, etc. To sum up, most of the car parts are designed by the car manufacturers themselves (including the design of hardware and software), and a small part is designed and produced by themselves.
We see the Volkswagen Beetle in front of the car, mainly designed for female friends, not only that, from the inside out are designed according to the female perception, so it looks beautiful, but it is not necessarily practical, and not necessarily very good off-road performance.
Modular design of wireless sensor network node hardware With the continuous improvement of environmental monitoring requirements, wireless sensor network technology has been widely used for its performance advantages of low investment cost, convenient erection and high reliability. Because wireless sensor network nodes need to realize the acquisition, processing, communication and other functions, so the use of modular hardware design can greatly improve the stability and security of network nodes.
Hardware environment construction In the actual development, we choose the wireless sensor network experiment of Jiangsu Xueli Information Technology Co., LTDPlatform, which integrates multiple features such as NB-IOT, LoRa, and ZigBee. Its modular design, such as replacement plug-ins, makes it extremely easy to build sensor networks. All operations, including the configuration of the NB-IOT module, are carried out on the LCD expansion board on the left side of the platform.
Wireless communication module: Wireless communication module is used to connect nodes to the network, usually using Zigbee, Wi-Fi, Bluetooth and other wireless communication protocols. Data storage: The data storage is used to store the data collected by the sensor and the relevant information during the node operation. Other modules:Depending on the application scenario, other modules, such as display module and control module, may be required.
Shanghai, December 6, 2017 - Harting's edge computing system MICA (Modular Industrial Computing Architecture) monitors machines and processes the data generated. To further expand its capabilities, Harting has collaborated with Arrow Electronics to develop a new MICA wireless sensor network solution that adds wireless communication capabilities to machine monitoring systems.
Requirements are as follows. Real-time software: Because of the unpredictable network changes, the software system can adapt to the dynamic and changeable network> First, find the power switch on the bottom of the wireless mouse. This switch is usually a small sliding button or switch marked with ON (on) and OFF (off) identifiers. Use your finger or fingernail to gently flip the switch to the ON position.
Open the back cover of the mouse and insert the battery. Open the back cover of the wireless mouse and insert the battery into the mouse. Remove the wireless receiver module. After installing the battery, remove the wireless receiver module of the wireless mouse. Insert the wireless receiver module of the wireless mouse into the USB jack of the computer, the computer is connected to the network, and it will update automaticallyInstall the driver.
The connection steps are as follows: Click Start to open the Settings. Select device options. Set the Bluetooth switch to the on position. Click Add Device to search for connected Bluetooth devices around you. 5. Tap the Bluetooth device you want to connect to. 6, click Connect, match. The match is successful.
Most wireless mice and wireless keyboards have switch buttons, generally located on the back of the keyboard and mouse, dial to the "OFF" position. There is no switch can open the wireless keyboard and mouse battery slot, remove the battery, can also achieve the purpose of closing. The switch is usually under the mouse, if notIt's a no-switch mouse.
