1. Monitor machine without voltage
(1) Power failure: This is a very simple fault, the general LCD display extension inside the power supply and external power supply two, outside the common some. Regardless of that power supply, its structure is much simpler than the CRT monitor's power supply, and is usually vulnerable to a number of small components, such as the safety pipe, Rectifier bridge. 300V filter capacitor, power switch, power management IC
U disk's composition structure is relatively simple, mainly by USB plug, crystal oscillator, the main control chip, voltage regulator IC (LDO), PCB board, SMD resistor, capacitance, Flash (flash), light-emitting diodes (LED) and other components. Also some u disk will be in usb+5v and voltage regulator IC string a 0 ohm maintenance resistor, now voltage regulator IC

1. Dip dual-row direct insert Encapsulation
Dip (dualin-line package) is an integrated circuit chip encapsulated in the form of Dual-row direct insertion. Most small-and medium-sized Integrated Circuits (IC) use this encapsulation form, generally, the number of pins cannot exceed 100. The CPU chip in dip package has two pins and needs to be inserted into the chip socket with dip structure. Of course, it can also be directly inserted into the circuit
According to the title, this blog article introduces this small example. The following blog summarizes JS Object-Oriented Knowledge.
The purpose of this small example is to understand JS Object-Oriented Knowledge. Take an example and try it. Then compare it with the system summary. This piece of knowledge is not very effective when watching videos. Many of them are in the fog.
In this example, it feels awkward. Because the Javascript language does not provide smart prompts in most cases. In ad
-impedance state, the two switches must be disconnected at the same time (or use a transport door on the output port), which can be used as the input state, some IO ports of the AVR Microcontroller are in this structure.
Characteristics and Application of Open leakage Channels
In circuit design, we often encounter the concepts of open drain and open collector.The "drain" mentioned in the so-called open-leakage circuit concept refers to the drain pole of the MOs. Similarly, the "set" in the open
During full screen program development, the current input method in the editing box needs to be determined in time to facilitate texture presentation on the interface. The following three steps can be used to complete this function:1. Add the relevant header file to the. h file.# Include # Include
2. Add the class definition used in the. h file.Struct s_uid: Public tuid{S_uid (int I){Iuid = I;}};

1. Read the IC spec carefully and we need to read some useful information from it. 1) IC correct (or can say accurate) power-up timing, which includes a host-side control IC when there are several pins (regulator, GPIO, etc.), these pin-tight on the point of timing is how. 2) when the IC power-on, the need to send
U disk's structure is relatively simple, mainly by the USB plug, the main control chip, voltage regulator IC (LDO), crystal oscillator, Flash (Flash), PCB board, SMD Resistor, capacitance, light-emitting diode (LED) and other components. Here are some of their respective roles.

Transistor as a switch, is the transistor working in the saturation zone, the NPN transistor as an example (all of the following)
As shown in the figure: when the vin=0, transistor b-e There is no forward bias, and cutoff, equivalent to the state of disconnection, at this time vce=vcc,c pole current ic=0;
When the transistor is closed (in the saturation zone), the load RC and transistor equivalent in series, through the RC current, through Ohm's Law,
1. The problem is at first
Today, looking at the feedback from the article "Interface inheritance declaration issues", I found that ninputer left such a question:
If there is
Class A:interface1
So
Class B:a, Inteface1
And
Class B:a
What would be the difference? What does the compiler do with the IL level to achieve this functionality?
2. Exploring Questions Understanding issues
The process of solving a problem is both a process of exploration and a process of reasoning and argumentati
We introduce JBoss AOP because our projects are used, the project is EJB, we need to use AOP to insert a layer to record the system log, and later may have to insert a layer of cache, and security control aspects.
Project-driven learning because our application server chooses JBoss and naturally uses JBoss's own more mature framework, JBoss AOP
Jboss AOP is a aspected-core framework that can be seamlessly integrated into any programming environment or with our application servers. Aspect-oriente
