A library that reads/writes INI files in LabVIEW. It is also the demo code for adopting LabVIEW Object Oriented Programming.

Maintained the the numeric controls and numerical calculations related LabVIEW source code.

A library that edits LabVIEW function palettes.

A library that reads/writes Windows Registry in LabVIEW.

A software platform for calibrating all NI hardware. Developed in LabVIEW and TestStand.

A set of LabVIEW template code, upon which developers can quick create a wizard UI style application.
Adopted several Object Oriented Programming design pattern in this project. (There is a significant difference between LabVIEW OOP and other languages': the objects in LabVIEW are passed by value from function to function, while the objects in other languages are mainly passed by reference. Thus, the common design patterns for Java and C# are not suitable for LabVIEW.)

A code generation tool. It automatically generates instrument drivers for LabVIEW.

A simple search engine.

Implemented the Support Vector Machine algorithm to recognize human faces.

Key technologies and tools: Machine Learning, Machine Learning, SVM, Convex Optimization.

Implemented a Convolutional Neural Network to recognize hand-written characters with high accuracy.

Key technologies and tools: Data Mining, Machine Learning, ANN, CNN

Designed and implemented three applications (in C# and LabVIEW):
A back-end service to dig out the frequent patterns from LabVIEW (a programming language) source code files, and save the results into a database.
A recommendation program to boost highly correlated functions(VIs), and code snippets to the users.
A static code analysis tool to analyze LabVIEW projects, and give suggestions of optimization.

Maintained the LabVIEW Find&Replace feature. Fixed bugs and optimized the code.

Established a framework plugin system to search information in LabVIEW and other NI software products.
Searched from both structured data (e.g. function library, UI components) and unstructured data (e.g. documents, on-line helps, web pages).
Developed the earlier version of this product in C++, then ported it to C#.

Key technologies and tools: .NET, WPF, MEF, Silverlight, Lucene, Qt

This project includes three parts:
1. Xerces and Xalan libraries wrappers in LabVIEW.
2. Porting Xerces and Xalan libraries to real-time operating systems, PharLap and VxWorks
3. A lightweight XML parser for LabVIEW imbedded applications.

This utility parses the Shared Libraries (*.dll file on Windows; *.so file on Linux; *.framework file on Mac OS), and wraps the functions in the Shared Libraries into VIs (LabVIEW functions). With the wrappers, LabVIEW users can call DLL functions in LabVIEW directly with LabVIEW native data types.

Key technologies and tools: Yacc, Bison

The calibration software for NI RF modular instruments.

A library of common data structures and generic containers for LabVIEW developers. Similar to the STL library in C++.

Windows installers for NI software products.

C and LabVIEW drivers for general instruments (eg. Oscilloscope, Spectrum Analyzer) that followed the IVI (Interchangeable Virtual Instruments) specifications and VXIpnp specifications.

The low level module that provides the interchangeability of instrument drivers. Developed in C++.

A higher level instruments driver. One Class Driver controls a class of instruments, while the specific driver only controls one instrument model. Developed in C++.

An application that simulate the behavior of general instruments on desktop computers. This project is developed in C.
