The document discusses various techniques for automated optical inspection (AOI), including 2D and 3D measurement methods. It covers topics like contour detection, parameter identification, image filtering, and classification of different material states. Experimental equipment and software are also mentioned. Examples are provided on measuring features like ball grid arrays, ferrules, and drill holes using AOI systems. Edge detection techniques with subpixel accuracy and circle fitting algorithms are summarized. 3D measurement techniques incorporating triangulation, moire, confocal microscopy, and interferometry principles are also briefly outlined.
Advantech has grown from a small Taiwan-based electronics exporter in the 1970s-1980s to a global leader in industrial computing and embedded systems. The company's CEO, KC Liu, outlined Advantech's history and future vision. [Advantech aims to reach $1B in revenue by focusing on customer-oriented business models and its 3-circle principle of tailored solutions. It also plans to build leadership in key vertical markets and achieve high customer satisfaction through localized, streamlined service globally.]
HSDPA (High Speed Downlink Packet Access) is an enhancement to 3G that improves downlink performance. It features Hybrid Automatic Repeat Request (HARQ) to reduce errors, fast cell selection to improve handovers, and Adaptive Modulation and Coding (AMC) to optimize data rates up to 10Mbps. New HSDPA terminals are required and initially offer download speeds of 3.6Mbps with later models reaching 14Mbps. HSDPA represents a significant step forward from 3G technologies.
