information on the screen, should be soft enough to fit into the photo. Choose the emotional graphics Each watermark theme in the creative, design stages have a lot of programs, individual themes in each version of the watermark camera to cover a variety of different designs to meet different permissions and different types of users. However, no matter what style of design, designers need to pay attention to and try to figure out the intuitive user experience of the design. Water

camera has been in the same period 2 db watermark, one is the decibel compass design, a falling leaves, singing birds, noisy horn as the element. We try to analyze different users ' different requirements for db watermarks to guess what elements they want to put on the screen. Finally with leaves, birds, horn and other graphics of the decibel watermark results are quite eye-catching. The watermark conta

Similar to the implementation of the previously described IDispatch, it is much easier to implement a connected object than the Mfc,atl, and it is done by using MIDL compilation to write IDL.Here we use ATL to implement a Speek component object that can be spoken through the Ispeek interface, according to the size of the decibel that is communicated to the client via a junction point.1.

Content: PSI is a type of pressure unit, defined as pound/square inch, 145psi = 1Mpa Quality traffic unit SCCM, standard-state cubic centimeter per minute DB is the unit of sound pressure level, which is recorded as DB and used to indicate the sound size. The most faint voice that human ears can hear is about 1 decibel, the stable breathing sound and the leaf swinging sound are about 10 decibel, And the

interference from nearby electronic devices during use, therefore, when setting the placement of wireless routers, we must remember to stay away from microwave ovens, refrigerators, and other household appliances. A good antenna is also an effective way to ensure the wireless transmission distance and Stability of routers. Some high-end wireless routers use dual antennas, generally, multi-antenna products are more secure than single-antenna products

equipped with an omnidirectional antenna, which is generally a standard dipolar antenna. This kind of natural signal waves often present three-dimensional "ring" coverage. Therefore, when the antenna is straight, the signal coverage in the horizontal direction is wider, while the signal coverage distance and intensity are not very good at the top and bottom of the antenna. Simulation of Wi-Fi signal propagation when an omnidirectional antenna is set up Take a 4-antenna wireless router as a

wireless transmission distance and Stability of routers. Some high-end wireless routers use dual antennas, generally, multi-antenna products are more secure than single-antenna products in terms of transmission performance. If possible, we try to choose dual-antenna or more antenna wireless routers. In addition, the antenna gain has an important impact on data transmission. Common routers generally only have 2dBi omnidirectional

the radiation to the human body, the power of the wireless router is generally not great, so we must grasp the layout well, it is best to see each other between the wireless router and the wireless router, and avoid wall blocking between them as much as possible. In addition, the capacity is greatly affected by the interference of nearby electronic devices during use, therefore, when setting the placement of a wireless router, you must stay away from the microwave oven, refrigerator, and other

wall blocking between them, especially the reinforced cement wall of the load-bearing wall ). We know that in order to reduce the radiation to the human body, the power of the wireless router is generally not large, so the capacity is subject to interference from nearby electronic devices during use, therefore, when setting the placement of wireless routers, we must remember to stay away from microwave ovens, refrigerators, and other household appliances.

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas. As a result, terminal antenna engineers are facing huge challenges: Antenna siz

Macro diversity In wireless communication, macro diversity refers to the situation where multiple sending antennas or multiple receiving antennas transmit the same signal, and the distance between these antennas is much greater than the wavelength. In a cellular network or wireless LAN, these antennas can be located
