Today's core language
At the Mobile World Congress in Barcelona, ​​Samsung Electronics has upgraded the GalaxyS series flagship phone. This fall, Apple will upgrade the iPhone as usual. According to the latest media disclosure, Apple's new mobile phone may increase the memory to 2GB, and the software-based "Apple SIM card" will anger the global mobile communication operators. For more information on technology, please pay attention to the daily electronic core morning newspaper.
First, communication news
1, 5G is coming? South Korea is the first to be launched in the 2018 Winter Olympics. On the occasion of large-scale networking of 4G, the industry has increased its horsepower and began to move toward the next generation of 5G mobile communication standards. At the Mobile World Congress, many companies announced their own 5G development strategy. The network speed of the 5G network will be as high as 10 Gbps, which is ten times that of the Gigabit fiber broadband. The 5G will be 100 times faster than the current 4G. The 5G network will further reduce communication delays while increasing the processing scale of data.
2, the software nature of the "Apple SIM card", will anger the global mobile communications operators. At the Mobile World Congress in Barcelona, ​​Samsung Electronics has upgraded the GalaxyS series flagship phone. This fall, Apple will upgrade the iPhone as usual. According to the latest media disclosure, Apple's new mobile phone may increase the memory to 2GB, and the software-based "Apple SIM card" will anger the global mobile communication operators.
Second, intelligent hardware
1. What is a selfie stick? The selfie stick was popular last year, similar to the camera's monopod, and can be stretched between tens of centimeters to one meter in length. As long as the camera device such as mobile phone and camera is fixed on the selfie stick, multi-angle and wide-angle self-timer can be realized through the Bluetooth connection. Because it is fun and practical, the selfie stick has been selected by Time magazine as one of the 25 best inventions of 2014.
2, Sony released a smart personal assistant, you can wander around. This shape is very similar to the smart device of Gundam's intelligent robot Haro, and the functions that can be realized are not uncommon. Like Amazon's Echo, when you call "OK, Speaker!", the built-in microphone recognizes and activates the system, and can set alarms, to-do items, make calls, and view weather according to the next voice command. And other functions. It sounds like the BSP60's selling point seems to be in a cute binaural shape, not in the features it has.
Third, automotive electronics
1. Qualcomm announced automotive solutions at MWC. Qualcomm announced at MWC that it has added a new 4G LTE modem to its automotive solutions to support all market-level connectivity in the automotive industry. According to Kanwalinder Singh, senior vice president of Qualcomm's technology business development, consumers expect all other connected devices, including their cars, to offer the same experience.
Fourth, semiconductor
1. Samsung relies on its own chips to completely kick off Qualcomm? The analysis said that this is difficult. Samsung Electronics hit Qualcomm, and the latest flagship machine, the Galaxy S6/S6 Edge, switched to its own chip, but it may be too early for Star to kick Qualcomm. Analysts pointed out that the 14-nanometer production capacity of the comet is limited, and it is divided into more than half by Apple's A9 chip. The future models should continue to use Qualcomm chips.
2, not afraid of Samsung and Intel 14nm offensive, TSMC 16FF jumped first . In the face of Intel (Intel), Samsung (Samsung) both announced that its 14-nm fin field effect transistor (FinFET) processor officially entered mass production, TSMC is not to be outdone, will mass production of 16 nm in the second quarter of this year FinFET's powerful version process (16FF+) boosts chip performance and power consumption; in addition, ARM and Xilinx have also unveiled 16FF+ related product blueprints, which will help TSMC in 1xna The rice process market pulled back a city.
V. Virtual reality
1. Microsoft will port Xbox games to holographic glasses. In the morning of March 5th, Phil Xens, head of Microsoft's Xbox business, confirmed at this week's San Francisco Game Developers Conference (GDC) that Microsoft will port Xbox games to HoloLens virtual reality headsets. In the device. He revealed that Microsoft's own studio is trying to develop an attractive experience and break through what Microsoft showed in January. But in the end, HoloLens will be open to outside developers.
Sixth, charging technology
1, mobile phone charging 2015 revolution, fast charge, wireless charging, type-c three arrows. In the face of domestic and foreign brand mobile phone manufacturers are planning to expand, coupled with mobile phone chip suppliers have also been implemented for many years, the global smart phone charging method is brewing a wave of new technological revolution in 2015, not only the mobile phone charging method will appear upward Upgrade the requirements of new specifications such as fast charging and type-c, and the new mobile phone charging method will be completely dominated by the wireless charging interface.
2. German scientists have developed "power generation shoes" or will be charging smart phones. According to the website of the Ministry of Science and Technology, scientists at a research center in Villingen-Schwenningen, Germany, have recently developed a kind of “power generation shoesâ€. The shoe collects energy while the human body is walking through two devices embedded therein. The two devices are the "vibration harvester" and the "swing harvester", respectively, designed with wearable electronics. When the walker touches the ground, the "vibration harvester" generates electricity; when the foot swings, the "swing harvester" generates energy.
A Dc Motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
DC motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger DC motors are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
