This article comes from the network, the author is unknown. This article mainly introduces the protection circuit of cell phone battery. All of us in the use of batteries will always occur when all kinds of misoperation, and cell phone battery is actually relatively fragile batteries, so complete protection measures for a qualified mobile phone battery is essential. The following is the text:
I. The protection of NI-MH battery
Cell Phone Ni-MH battery protection device is very simple, which is
not copy the copy. The procedure is as follows:# Include Void pt (int * pta, int * ptb){Int * ptc;Ptc = pta; pta = ptb; ptb = ptc;}Void ref (int ra, int rb){Int rc;Rc = ra; ra = rb; rb = rc;}Void main (){Int a = 3; int B = 4;Int * pa = a; int * pb = B;Pt (pa, pb );Printf ("zhizhen: a = % d, B = % d \ n", a, B );Ref (a, B );Printf ("yinyong: a = % d, B = % d
of PTC polymer auto-recovery fuses at a certain ambient temperature.Rmin = minimum device resistance at 25 ℃ prior to tripping.
The minimum resistance of the device before the mutation at 25 °, which determines the minimum operating current of the polymer auto-recovery fuse.
Rmax specifies the highest resistance for the supplied polymer auto-recovery fuse.
R1max = maximum device resistance measured in the nontripped state 1 hour post reflow.
R1max is
the next generation of mature, innovative PCB design ideas of the foundation. The new XpeditionThe release features advanced layout automation to address increasingly complex issues in high-speed design, as well as emerging means for high-end computing chipsetsSouth. The following key features help optimize the performance of your design:Label routing, used to minimize crosstalk and impedance discontinuity of the interconnect geometry, can be created and modified on high-speed traces.Designers
What is PDM:
Product Data Management manages design, R D, manufacturing, and other data. The Design and R D data must be synchronized with the manufacturing data, which must be paperless.
Data managed by PDM includes:
Design Information of CAD, cam, and CAE-bom, configuration file, and design File
MRP and CAD Synchronization
Process Information: workflow, approval relationship, etc.
What do PDM software have? Storm history:
IMAN--UGS
Windchill -- PTC
. Use features to "automatically analyze the objects on the stack when they leave the scope"
2. for the dynamically allocated memory, the function scope is manually controlled by the programmer, which brings convenience to the programmer but inevitably avoids Memory leakage caused by negligence. After all, only the compiler is the most reliable.
3. auto_ptr builds an object A on the stack. In object A, wrap dynamically allocates the memory pointer P. All operations on the pointer P are converted
Source: Lithium Battery Protection Board basic knowledgeFirst, the origin of the protection plateLithium-ion batteries (rechargeable) need to be protected, it is determined by its own characteristics. As the material of the lithium battery itself determines that it can not be overcharge, over-discharge, over-current, short-circuit and ultra-high temperature charge and discharge, lithium battery components will always follow a delicate protection plate and a piece of current safety device appears
memory, the function scope is manually controlled by the programmer, which brings convenience to the programmer but inevitably avoids Memory leakage caused by negligence. After all, only the compiler is the most reliable.3. auto_ptr builds an object A on the stack. In object A, wrap dynamically allocates the memory pointer P. All operations on the pointer P are converted to operations on Object. In the destructor of A, the space of P is automatically released, and the Destructor is automaticall

As for routers, I like routersim2.0. I think it is suitable for ccna. Test simulator is best for boson, boson router test3.38

To sum up, we have the following experiences:
Have a good grasp of the OSI reference model and TCP/IP model; have used Cisco's low-end routers; Have some foundation for the operation functions of switches;

communication line is long or there is an outdoor air line, lightning will inevitably cause overvoltage on the road. Its energy is often huge, and users often say with frustration: "dozens of connected PLCs are all broken! ".Iii. solution:1. Consider from the PLC:● The 24 V power supply and 5 V power supply are isolated from each other using an isolated DC/DC. The same is true for the PROFIBUS interfaces of Mitsubishi, OMRON, Schneider PLC, and Siemens.● High-speed RS485 chips with complete pro
