Goals
• CPU bootloader (zboot2) is now digitally signed and optionally encrypted • xos, starting with version Ma6, will enforce the verification of the digital signature • OS kernel is also digitally signed and optionally encrypted • zboot2, by using xos functions, will enforce the verification of the digital signature of the OS. • The process does not require a secure manufacturing line

Signal strength and Modulator Gap
The smaller the modulator gap the larger the amplitude of the generated wave.
Criteria to chose gap size:
Flowrate Depth LCM Mud type Mud solids content

Data Modulation/Demodulation
Data from the MWD tool is sent from downhole as a stream of binary bits. 1’s and 0’s.
Sensors at surface send the signal to the logging unit.

Signal Power
Signal Strength is related to the amplitude of the signal
SS = rms amplitude of signal e.g sine wave = A/2

在点/线数据已经加载进来以后，用户可以在 任何时间将其转换为线/点数据。
加载
1- 从文件菜单中选择“打开参考工区 ”
从其它工区中获取数据
2- 从一个工区里拖住一个数据，放进另 一个工区，实现工区间的数据传递。

• 存放所有的模型，包括含 有断层，zone和属性的 3D网格。
断开polygon边线
用“Edit polygon lines”( 编辑多边形边线)来编辑 polygon边线
编辑输入数据
操作和运算器
1。 右键点击文件名并选择设 置 2。 进入操作窗口
典型的数据文件类型包括， 线，点或者2D网格。
运算器中所有的操作也存在 于操作窗口下。
3。 选择合适的操作
• Polygon Operations 是用来对已经存在的 polygons以及属于polygon的点进行操作。 • Make/Edit polygons process：对 plolygon的各种操作，包括： 创建新polygons ， 在合适的位置将其分开，通过点击和移动对每 一个点或者线进行编辑。交互编辑。
