Although BlackBerry's first-generation Playbook tablet was defeated, RIM did not plan to abandon the tablet market. According to foreign media reports, the BlackBerry product roadmap has recently been leaked. The roadmap shows that RIM plans to launch two BlackBerry Playbook tablets in 2012. One of them is a 7-inch 3G+ tablet PC, which is expected to be released in April. The other is a 10-inch PLAYbook tablet supporting LTE, which is expected to be released in December at an interval of about 8 months. Information about the specific hardware specifications of the two tablets is not yet known. The media speculated that the 3G+7-inch Playbook may not be able to support LTE like a 10-inch tablet due to chip limitations, but both tablets will have higher-resolution screens. .
In addition, the first BlackBerry "London" with the BlackBerry 10 operating system will be released in September this year. In fact, the BlackBerry "Colt" was supposed to be the first smartphone running the BlackBerry 10, but unfortunately was canceled by RIM and suffered an abortion. .
According to reports, RIM will preview BlackBerry 10 at the Mobile World Congress next month, but viewers can only watch with their hands motionless because it will be separated by glass. Interestingly, while RIM is launching the new system, it is also discussing the sale of the company with Goldman Sachs Investment Bank.
The New Electric Power energy stabilizer is a device to stabilize the input voltage, which is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the voltage fluctuation is caused by the voltage fluctuation or load change of the external power supply network, the control circuit will sample, compare, and amplify, and then drive the servo motor to rotate, so that the position of the voltage regulator changes. By automatically adjusting the coil turn ratio, the output voltage can be automatically maintained stable. It has the advantages of large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc. It is applicable to a wide range of loads, can withstand instantaneous overload, can work continuously for a long time, manual/automatic switching, is equipped with overvoltage protection, phase loss, phase sequence protection and mechanical fault automatic protection, and has the advantages of small size, light weight, convenient use and installation, reliable operation, etc
