Most people go to Starbucks for three purposes: drinking coffee, rubbing Wi-Fi, and charging their cell phones. The problem, however, is that the first two purposes are easier to achieve and the number of seats near the charging outlets is limited. In case you hit a few customers charge seat, then you do not wait.
With the ever-increasing number of intelligent terminals owned by individuals, how to charge these terminals more conveniently has become a major direction for the industry to explore. According to a survey conducted by the US market research firm IHS, about 70% of smartphone users charge their cell phones at least once daily, and 30% charge more than twice daily. Therefore, the emergence of wireless charging technology, intelligent terminal charging method has brought the possibility of revolution. Recently, Starbucks launched the latest services in the United States, will gradually set up free mobile phone charging points in various stores, and in Los Angeles for the first time try.
Driven by technological evolution and demand, wireless charging technology is rapidly maturing and has become a reality. So, wireless charging technology is what will be a flash in the pan, or the future trend? We are really about to enter a charge without "line" era?
Wireless Charging technology comes from wireless power transmission technology. Also known as inductive charging, non-contact inductive charging, is the use of near-field sensing, that is, inductive coupling, by the power supply equipment (charger) is the energy transmitted to the device, the device uses the received energy to charge the battery and At the same time for their own use. Due to the inductive coupling between the charger and the power device, no electrical connection is required between the two devices. Therefore, the charger and the power-using device can be exposed without any conductive contacts.
The current mainstream wireless charging technology are -
Electromagnetic induction charging the primary coil of a certain frequency of alternating current, the electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmitter to the receiver. Currently the most common charging solution on the use of electromagnetic induction. In fact, the electromagnetic induction solution is not mysterious in technology implementation. The patent of non-contact inductive charger applied by BYD back in 2005 uses electromagnetic induction technology.
Magnetic field resonance charging consists of an energy transmitter and an energy receiver. When the two devices are tuned to the same frequency, or resonate at a specific frequency, they can exchange each other's energy, a technique currently under investigation. Not long ago, a research team at the Massachusetts Institute of Technology (MIT) used the technology to light a 60-watt bulb two meters away and name it WiTrici ty.
Radio wave charging This is the development of more mature technology, similar to the early use of ore radio, mainly by the microwave transmitting device and microwave receiving device, can capture the rebound from the wall of the radio wave energy, with the load to make adjustments Maintain a stable DC voltage. This method requires only a wall-mounted transmitter and a "mosquito" receiver that can be mounted on any low-voltage product.
No longer "specifically looking for a time charging"
Starbucks has said it will set up 100,000 free "Powermat Spot" free wireless charging stations in the United States at 7,500 stores, including the Teavana Tea Bar, and try out trials in the Los Angeles Bay Area. In the future, consumers will get rid of the power outlet, simply phone on the desktop special equipment, you can achieve cell phone charging. "Powermat" looks like a small black disc, it can continue to play out low-power, convenient for consumers to enjoy coffee at the same time, all kinds of portable mobile terminal charging.
Welded mesh is mainly used on the surface of the rock layer to prevent the rock from falling after being broken. The welded mesh is linked with a large number of bolts to form an integrated support system, which greatly improves the safety of the mine.
ANTO welded wire mesh is made of high-strength steel wire, welded by high-frequency welding machines. the welding are not easy to crack.
In coal mine roadway support,coal mine steel mesh is used in combination with steel mesh, bolts and joists,to form an integral bearing structure with bolts as the mainstay. It can increase the bearing area of the bolts, prevent small turquoises from falling between the bolts, greatly improve the overall supporting performance of the bolt system, and make it possible to apply the bolt support to the conditions where the roof is relatively broken or the joints and cracks are developed. And in the roadway affected by mining. Moreover, it can also be used in the case of a large roadway width, thereby significantly improving the supporting effect of the bolt and further expanding the application range of the bolt supporting.
Advantages of welded mesh:
1. Made of high-strength steel wire
2. High frequency welded, not easy to crack
3. Black or hot-dip galvanized
