Recently in the study of computer networks, the browser's HTTP request message has been known, found an interesting phenomenon. Search for a moment, find the following article, laughing at me.
Are you curious about the user-agent that identifies the browser identity, and why each browser has the Mozilla word?

accelerometer is the data obtained by the accelerometer minus the gravity impact.
The Unit is m/s ^ 2, and the coordinate system is the same as the acceleration sensor.
The formula for calculating the accelerometer, gravity sensor, and linear accelerometer is as follows:
Acceleration = gravity + linear acceleration

11 Rotating Vector Sensor
The rotational vector sensor is referred to as rv-sensor.
The rotation vector represents the direction of the device and is a mixture of axes and angles to calculate the data.
Rv-sensor output Three data:
X*sin (THETA/2)Y*sin (THETA/2)Z*sin (THETA/2)
Sin (THETA/2) is the order of magnitude of the RV

When you don't need to get the registry data type and as long as the value is very simple: you can use Get-itemproperty:
Copy Code code as follows:
Get-itemproperty-path Hklm:\software\microsoft\windows\currentversion\run
If you need to get the data type, you need only a few more steps:
Copy Code code as follows:
$key = Get-item-path Hklm:\software\microsoft\windows\currentversion\run
$key. GetValueNames () |Foreach-object {$ValueName = $_
