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 measurem

From 1966 to 2016, exactly the past 50 years, the last 50 years of computer vision development is very fast. Does computer vision become a very mature and perfect technology today? Not.For example, under the blue sky, the highway has a big white truck, the computer may say, this is a white cloud. Everyone might have thought about it. This is a tragedy: a Tesla has not detected the truck, so that the high-speed Tes
The NVIDIA product classification has been unclear.

Shortly thereafter, another American scientist Tesla (Nikola Tesla) invented alternating current, which can be transmitted over a long distance, which not only expands the range of powe
2iSome years ago I started work on my first CUDA implementation of the Multiparticle collision Dynamics (MPC) algorithm, a Particle-in-cell code used to simulate hydrodynamic interactions between solvents and solutes. As part of the This algorithm, a number of particle parameters is summed to calculate certain cell parameters. This is in the days of the Tesla GPU architecture (such as GT200 GPUs, Compute Capability 1.x), which had poor atomic ope Rati

When I was a child, I read Edison's article, saying that after 1001 experiments, I successfully invented the lamp. Coupled with the environment, the teacher taught me that "failure is the mother of success". This idea is deeply rooted in my heart.
Today, I believe many people are deeply rooted in this idea.
However, history tells us that the invention of a light bulb is not just a credit of Edison alone. Even look at the history of Tesla and others (a

For this reason, he also bought a Tesla and parked it downstairs. After all the connections were established, he waited for hack. A Tesla is very valuable and has no sponsorship. Even the market cost is too high. I asked myself that I could not do this for the pursuit of technol
. Secondly, geeks have 10 times higher requirements for their own products than those on the market, so they generally do not release products easily, but each release will bring users a "stunning" or "shocked" feeling, the target user loyalty must be enhanced to the maximum extent. Finally, the products brought by geeks are usually reported by various media to the greatest extent. Therefore, the marketing cost is reduced, so that the wine is not afraid of going deep in the alley!

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.
Place the mobile phone on the desktop. The default X axis is 0, the default Y axis is 0, and the default Z axis is 9.81.
Place the phone down on the desktop, and the Z axis is-9.81.

group of researchers at Max Planck sort ut. NVIDIA is a company that has lived on Raster hardware for more than a decade. It has no strength in the field of ray tracing to compete with Intel, lack hardware support, and lack of developers. From a technical point of view, NVIDIA will be an important competitor in the future, rather than AMD/Ati. AMD has a gray face everywhere. The CPU won't work for Intel, and the GPU won't work for NVIDIA. I really don't know what AMD's fate will be like in the
