I. Introduction
The ANR problem is a common and troublesome problem in Android. It is difficult to analyze the cause in many cases.
Ii. ANR Definition
Next let's take a lookBaidu encyclopediaDefinition for ANR:
ANR problems are often caused by complex and time-consuming operations in the main (main thread) thread, such as file IO, network access, and infinite loops. Finally, ANR is throttled by the system.

If the module is normal, but more bad, you can start from level 02 automatic calibration (self-test).
Risk: ATA module will be lost, (K8k9k10 will also lose the app module) after running, to write back the original disk ATA firmware and app module.
If the bad way is not much, you can start the calibration from Age26 or Age30, Age31, and not destroy the ATA
Run normal to AGE=50 will stop (many are abnormal end, more is at age=4f end), the calibration process can be a point semicolon at any tim
in the three-dimensional point cloud. But the realization is not very ideal, if the disparity map of the quality is not high, not detect the contour, not trigger this function, let alone distance. So in my program, the way to get distance is to use the mouse point parallax map of a point, it will show the distance of this point, but so far information is not very accurate, there may be some parameters are not done.
It is important to note that for two cameras, there is only one parameter matrix
you determine if the cable that you have installed exceeds the specified length? Microscanner Pro uses TDR technology to obtain accurate length measurement results to make it easier to determine whether the cable length meets the standard.
1th step, insert the network cable. Plug one end of the twisted pair (or known length) into the "MAIN" port on the micro-scanner, and the other end is vacant.
The 2nd step is to calibrate the NVP value. NVP (nomina

management function of touch screen. Boff: True indicates power off, and false indicates power on. It only calls the ddsitouchpanelpowerhandler () function, which is generated when the function enters or exits the poweroff state.
Touchpanelcalibrationapoint ()
This function is used to calibrate the input touch screen coordinates and convert the touch screen coordinates to the display coordinates, the formula SX = A1 * Tx + B1 * ty + C and SY = a2 * T
1. Touch Screen calibration principle
For more information, see http://blog.sina.com.cn/wyw1976.
2. General Method of touch screen Calibration
The following formula is used to implement touch screen correction. XL, yl are the display coordinate, XT, and yt are the touch screen coordinate,
XL = XT * A + yt * B + C;
YL = yt * D + yt * E + F; formula (1)
Because the specific calculation is to be an integer operation, the abcdef actually saved is an integer, and a parameter div is added, which is
developer, can use to sample and calibrate the screen with the touch screen DRIVER:
Call the touchpanelenable function to start the screen sampling.
Call the touchpanelgetdevicecaps function to request the number of sampling points.
For every calibration point, perform the following steps:
Call touchpanelgetdevicecaps to get a calibration coordinate.
Draw a crosshair at the returned coordinate.
Call the touchpanelreadcalibrationpoint

This function is used to calibrate the input touch screen coordinates and convert the touch screen coordinates to the display coordinate
, you can use the QT plug-in system to add it to QT and set the qws_mouse_proto environment variable. You can use the following method to set the qws_mouse_proto environment variable:
Export qws_mouse_proto = "tslib:/dev/ts"
The parameters are separated by:. The first parameter tslib specifies the mouse driver to be used, and the second parameter specifies the name of the mouse device corresponding to the driver.

Automatic parallelism in Oracle 11gR2
In Oracle 11.2.0.2, automatic parallelism can be used only when I/O statistics are collected. When parallel_degree_policy is set to auto, the Oracle database determines whether to use Parallelism Based on the cost and hardware features of the operation in the execution plan. When parallel or parallel (auto) is used at the statement level) it indicates that automatic parallelism is used regardless of the value set by parallel_degree_policy.

tolerances. This is the first level measurement. All connectors should be cleaned before each measurement. To avoid measurement errors, two instruments (generator and receiver) should use the same measurement cable (such as 3 meters long ). These cables should have the same characteristics as the optical fiber core.
The test can be carried out in two ways: one tester performs the test, the two instruments are placed in the same place, but can form a loop with the other; the two testers, there i

Camera calibration methods are divided into three categories: traditional camera calibration method, active Vision camera calibration method, camera self-calibration method.Traditional camera Calibration Method: Features: The use of known scene structure information, commonly used to the calibration block; Advantages: can be used for any camera model, calibration accuracy is high; insufficient: The calibration process is complex and requires high precision known structure
