Acceleration sensors may be the most mature mems product. There are many types of acceleration sensors on the market.
Commonly used acceleration sensors in mobile phones include BOSCH (BOSCH) BMA series, AMK 897X series, and ST LIS3X series.
These sensors generally provide an acceleration m

Interpretation of sensor event values in Android devices
The acceleration sensor, also known as G-sensor, returns the acceleration values of the x, y, and z axes.
This value contains the influence of gravity, measured in m/s ^ 2.

instantiation: Creates an instance of a class, the concrete object of the class.
method: a function defined in a class.
object: An instance of a data structure defined by a class. The object consists of two data members (class variables and instance variables) and methods.

Last Sunday, I heard a call from the company's partners, saying that I had to quit when I heard it. It took me a long time to respond. The first time I encountered this in my career, the first reaction was "what happened to the company? ".
Of course, I am not a partner of the company. I am only an android engineer in a 16-person team who has been working overtime for three months on and off. I thought that the android client could be paused, but suddenly ended.

team initiated by others. If the project is self-led and with confidence and expectation, it is easier to cut your income to control costs and extend the use time of the first financing.
If you team up a team based on the value of a large company, even if it is only a team of seven or eight people, the labor cost for one year will soar to more than 2 million (+ 4 gold). In addition to other costs, at least 3 million will be burned in a year, the c

The Fund was provided by a venture capital company headed by FidelityGrowthPartners, which was also the first venture capital company to invest in financing.

Low returns mean that the financing cost of B is low, the lower the agreed yield of grade A, the lower the financing cost of grade A, if two grade B tracks the same index, the position is the same, but one financing cost is 6% and the other is 7%, then the net value of the preceding grade B will be 1% higher than that
