The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

函數分庫函數和用戶自定義函數兩類： 庫函數（又稱系統函數）是高級語言軟家中提供基礎功能的函數。庫函數文件以h為文件后綴，如C語言的stdio.h文件包括了printf(), scanf (),open(),close()。C語言中主函數要使用某庫函數：#include<庫函數文件名>

這是一個用線程實現的圖形動畫實例，每當鼠標點擊一次“Start”按鈕，屏幕上將產生一個隨機顏色的小圓球，該圓球將在屏幕上發生碰撞跳動，直到點擊“close”按鈕為止。該實例由5個類構成，分別放在以下4個文件中：Ball.java、BallCanvas.java、BallThread.java、BounceFrame.java。主類是BounceFrame。

SENTINEL 的加密狗lic生成工具方法如下 1.copy a870.sentinel to windows\system32 folder. 2.run Emulator Utility and then press install button and close the utility. 3.run wechoid.exe, selector must be 1e or 1c 4.then run LicGen and use selector and code from wechoid.exe w/o 0x, it will make a license for that pc

pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of an audio, video, or image file that is mathematically based on the audio or visual content contained within. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the inputs are visually or auditorily similar. As a result, perceptual hashes must also be robust enough to take into account transformations that could have been performed on the input.

Linux系統中，設備驅動程序是操作系統內核的重要組成部分，在 與硬件設備之間建立了標準的抽象接口。通過這個接口，用戶可以像處理普通文件一樣，對硬件設備進行打開(open)、關閉(close)、讀寫(read/write)等操作。通過分析和設計設備驅動程序，可以深入理解Linux系統和進行系統開發。本文通過一個簡單的例子來說明設備驅動程序的設計。
