Knowledge Point Analysis:
NFC (Near Field communication) is close-range wireless communication technology. Developed by Philips and Sony, NFC is a non-contact identification and interconnection technology that enables close wireless communication between mobile devices, consumer electronics, PCs, and intelligent control tools. NFC provides a simple, touch-only solution that allows consumers to easily and intuitively exchange information, access content and services.
Operation Steps:

code to release an unmanaged resource, the GC calls the Finalize method to release it. The Finalize method does not directly release the unmanaged resource, but instead calls Dispose (false) to release it. Since. NET2.0, C # cannot directly override the Finalize method, which is implemented by a destructor, which in IL is interpreted as:

series resonance circuit, which is the same as the frequency of the reader, in this way, under the electromagnetic wave excitation, the LC resonance circuit generates resonance, so that the capacitor has a charge. At the other end of the capacitor, there is a one-way conduction electronic pump, the charge in the capacitor is sent to another capacitor for storage. When the accumulated charge reaches 2 V, the capacitor can be used as a power supply to provide the working voltage for other circuit
NFC Definition
Near-Field Communication (
English:Near Field Communication ,
NFC ), Also known
Short-range wireless communication It is a short-distance high-frequency wireless communication technology that allows electronic devices to transmit non-contact point-to-point data and exchange data within 10 centimeters (3.9 inches. This technology evolved from contact-free radio frequency identification (RFID, which is widely used in public transit s

Internet of Things (IOT) refers to the use of various information sensing devices, such as RFID) devices, infrared sensors, global positioning systems, laser scanners, and other devices are combined with the Internet to form a huge network. The purpose is to connect all items with the network for easy identification and management. Iot is built using ubiquitous network technologies. The most important technology is the
MES manufacturing execution system is a set of software for effective management of workshops. It can supervise, track, manage and control workshop production activities to achieve visual management and agile manufacturing of workshops. The MES manufacturing execution system can exchange data between the control layer and the underlying control layer of the ERP system in real time, and can also be integrated with other manufacturing information management within the enterprise, the seamless inte

I bought a second-hand CF card online. Take it back and use the data recovery software. There are several photos of criminal cases on the scene, with bloodshot spots. He also shot the victim. I don't know which police station has eliminated this card. If the investigation is initiated, some people must be affected. This kind of thing will not happen in the Age of film. But today, new pr
. There are two computers, one server, and the configuration is very high and the running speed is very slow. So far I have not figured out that the 32 GB memory is so slow, because the system is Windows Server 2008? The other is the monitoring computer, Dell's desktop, which is not connected to the Internet so far. It is very fast and uncured. I wrote code on the monitoring computer and copied it to the server to run (test ).

I believe everyone is clear about the mainstream wireless protocols. This article will introduce the wireless network protocol RuBee. Although it is not well known, it also has broad application prospects. I hope this article will help you.
You are familiar with ZigBee and are seeking for WiBree usage. Now you need to get familiar with another wireless network protocol RuBee, also known as IEEE 1902.1. Retailers and manufacturers can select this new standard outside of

The 2-generation GC recycles the Gen 0 heap, Gen 1 heap, and Gen 2 heap, and Gen 0 and Gen 1 are smaller, and the two generations are always around 16M, and the size of the Gen2 is determined by the application and can reach a few g, so the cost of the 0 generation and 1 generation GC is very low, The 2-generation GC, called full GC, is usually expensive.
