Yesterday the company bought a few Sonos wireless hifi equipment, beans need to test the effect.As a simple test, my structure is very simple, the router (firewall) comes out to pick up the Cisco switch, then boost and my controller (computer or phone) are on a VLAN, and then between boost and player through the grid wireless network connection between themselves.Routers-Switches-SONOS boost/controller-----
First, to understand their own charging treasureThere are generally several data on the charging treasure: battery capacity Capacity (mAh), input current (a), output current (a), input voltage (v), Output voltage (v)The power of the rechargeable battery is mah (mah), which is the product of the current intensity and time, and when the current intensity is in mah (MA) units, the time is measured in hours (h), and the two are multiplied by mah (mah). It

F-type battery, now a new generation of power battery products, there is a trend to replace lead-acid maintenance-free battery, generally used as the battery core (personal opinion: in fact, it is too big, it is not easy to use independently, haha ). Standard N (flat head) battery height 89.0 ± 0. 5mm, diameter 32.3 ± 0. 2mm.
We have noticed that the positive electrode of the battery is flat and has no protruding points. The battery Cores Used for battery spot welding are used, generally, t

. Second, the type of commonly used batteries: alkaline batteries, carbon batteries, rechargeable batteriesHousehold batteries are generally divided into dry battery and rechargeable battery two kinds. Dry battery is a disposable battery, can not recharge, commonly used dry battery type has alkaline battery and carbon battery, operating voltage 1.5 volts. The rechargeab
Generally, If you specify the class attribute for a bean, the Spring IoC container is required to call the constructor to create a bean.
As follows, there is a product class, which has two sub-classes: Battery and disc.
Product class:

I. knowledge points
The purpose of the static factory method is to encapsulate the object creation process in the static method.Customers who request an object only need to call this method and do not need to understand the details of the Creation.
Spring supports calling a static factory method to create beans. This factory method should be specified in the factory-method attribute.

after the power outage, a rechargeable battery is applied to the array card buffer unit. Today, most of the array card cache units add a rechargeable battery pack, which provides power support for the cache after a power outage, while ensuring that the data is not lost for a certain amount of time (typically 48 hours). Until the next time the server recovers power again, the array card controller will flus
produce the final high-quality images.
Which format is the best? This is an issue of "adapting to local conditions. Tiff and raw can achieve the highest image quality, but JPEG files only occupy a small storage space. For most photographers, JPEG files with the lowest compression ratio (the highest quality) are the best choice. For those who are particularly pursuing high quality, the tiff and raw formats are more suitable.
Macro focus: most medium and high-grade digital cameras have macro s
, low self-discharge rate, and many battery cycles, but the price is relatively high. Due to its low capacity, serious self-discharge, and environmental pollution, nickel-cadmium batteries are gradually being eliminated. Ni-MH battery has a high performance price and does not pollute the environment, but the single voltage is only 1.2 V, so the use range is limited.
Ii. Lithium Battery features:
1. higher weight-energy ratio and volume-Energy Ratio;
2. the voltage is high. The voltage of a

Both Ni-Mh and lithium rechargeable battery have their own usage skills. Ni-Mh rechargeable battery has a memory effect. Try to use the battery power before charging. Generally, the
We have tried to define the class. Define a class, which is to create a new kind (type). With the class, we then construct the object of the corresponding type. Further, each type should also have a clear interface (interface) for use by the user.
We can use other objects in the definition of a new class. This is the combination (composition). Combination is one of the basic means of implementing program reuse (Reusibility) in Java.
Combination and "Has-a"

Household batteries
The connection method of battery series and parallel connection mentioned above is for rechargeable battery packs. The battery in these battery packs are permanently welded together. In addition to attaching several batteries to the Battery room where the battery is installed, the rules described above also apply to household batteries. When connecting several batteries, you must follow the following basic requirements:

. So it's easy to say that if you want to pass all the content through a cable, HDMI is the best choice.
However, depending on the different equipment, HDMI is sometimes not the best choice, if your family's equipment has a certain age, and just need to sound bar such a simple sound output device to connect to the TV, then the fiber audio is a good way to connect. In this case, sometimes the only option is not to worry too much about HDMI. For most simple sound devices, fiber and HDMI are actua
