Title: Robotic Eye Inside Pipe (REIP) - View Into Unreachable Place
Home-grown small pipeline inspection system to inspect pipeline interiors welding quality for pharmaceutical industry and food industry, diameter range from 12 mm to 75 mm. Non-destructive video inspection is required from recent government law enforcement to above industry to increase safety standard and environmental contamination control on above industry facility pipe line and sewage system. Video evident of the interiors of pipelines for welding defects such as surface discontinuity, corrosion fatigue cracking, creep of dissimilar weld joints and piping conditions such as leakage and blockage is done yearly by pipe line inspection service's consultant company.

Title: TE 8000 - Wafer Bumping Stencil Inspection System
This invention of the first industrial scanning technology to inspection 12 inches wafer bump stencil (300mm) diameter with more than 1 million apertures, which aperture size is 75 micron in diameter with single pass scan :
- Single pass scan for 8x8 inches wafer bumping stencil, by 3200dpi resolution and its optical accuracy achieved 7 micron
- Single pass scan 12x12 inches wafer disk, by 2400dpi, resolution and its accuracy achieve 11 micron
Green color spot show dust / stain appear on wafer stencil, red color spot shows missing apeature detected. Due to the wafer stencil surface is dirty, system detect a lot of stain from the image captured. Further research and implementation on hardware and software are required to reduce the errors in detection.
* This project has awarded with entrepreneurship (CIP) grant by CRADLE in year 2008

Title: ASIS PCB, Advance Stencil Inspection System
Automatic human eye independent QC tool for stencil inspection
Capability:
Check missing, extra, position offset and area defective aperture
ASISTM is a fully integrated, stand-alone measurement and inspection workstation for stencil and screen fabrication or other machined, etched or laser cut eform operations.
ASISTM uses a PC Windows based software package integrated with a high-resolution, calibrated, A3 size flatbed scanner. This combination allows inspection of both stencils and screens for accuracy and the ability to inspect and measure 100% for absence/presence and correct size of apertures.
* Awarded with pre-seed entrepreneurship grant by MDEC.

Title: Electronic Machine Inspection and Verification System
Software and hardware design in optical inspection technology effectively prevent human error in product labeling process in a manufacturing system. This technology consists of camera, video card, computer and image processing software to replace human eye and mental comparison process(brain), which is known as not reliable and error prone when dealing with repetitive tasks.
This proprietary solution prevent human mistake happen at the source, verify the source input data in text form against with machine first output unit. Therefore, it totally eliminate possibility of catastrophic product scrap cost, quality and reputation loss. Other competitors system provide solution in the area of verify the 'first output actual unit' against subsequence units. This comparison method only good for solving mix device and product segregation after mass production.

Title: Dual Camera AOI Reject System
This solution is using the capability of vision inspection system to check front and back label to eliminate wrong filling bottle send to customer. Innovation solution proposed to customer in using 2 cameras, each camera was fixed to view each site of the bottle during production. The image content from 1 site of a bottle will be compared to the image content from the other site of the bottle. The image content from each site of the bottle is captured and send to computer for further process. Propietary algorithm has been used to perform comparison between these 2 image content. For content that not match, a reject signal will be sent to a 'Pusher', whcih conntected with a PLC and sensor, from computer to eliminate the bottle from further process.
