Openability: producing design limits for consumer packaging

Openability of consumer packaging is becoming a major issue as the demographics of society are changing and society is getting older. Sadly, ageing brings with it many issues, not least a loss of strength and dexterity. In order to design effective packaging, understanding the ability of aged consumers is crucial. This paper outlines the development of a torque‐measuring device and the results obtained to date. Copyright © 2006 John Wiley & Sons, Ltd.

多次散射激光雷达接收信号的模拟

MonteCarlo方法模拟多次散射激光雷达接收信号是一种经典方法，但这种方法的最大缺点是计算时间很长．为提高计算效率，本文在传统的半解析MonteCarlo方法的基础上，使用Henyey－Greenstein函数的修正公式来表示散射相位函数，计算出每个散射点处光子不发生进一步散射而直接到达接收机的概率．模拟结果显示，一、二、三次散射起主要作用，但随着海水衰减系数和接收机视场角的增大，高次散射对激光雷达的接收信号的作用也越来越强．     

Flash memory architecture

Flash memories entered the nonvolatile memory scenario only a few years ago, and now these kind of memories are battling to substitute either EEPROM or EPROM. In fact, their peculiarities are becoming quite interesting in present day applications.In system updating, low power consumption, embedded algorithm for program and erase, high density, low cost packages are some of the items which are making the Flash grow in the nonvolatile memory market share.Some words must be spent in explaining what the market is asking of Flash, which are the main applications for these memories, and how their architecture is arranged.The Flash memory cell behaviour will be described, then the fundamental operations (read, program and erase) are explained and some words are used to introduce the redundancy and device testability concept.     

Localized CO2 laser bonding process for MEMS packaging

The packaging poses a critical challenge for commercialization of MEMS products. Major problems with the packaging process include degraded reliability caused by the excess stress due to thermal mismatch and altered performance of the MEMS device after packaging caused by thermal exposure. The localized laser bonding technique for ceramic MEMS packaging to address above-mentioned challenges was investigated. A continuous wave CO2 laser was used to locally heat sealing material for ceramic MEMS package lid to substrate bonding. To determine the laser power density and scanning speed, finite element analysis thermal models were constructed to simulate the localized laser bonding process. Further, the effect of external pressure at sealing ring on the bonding formation was studied. Pull testing results show that the scanning speed and external pressure have significant influence on the pull strength at the bonding interface. Cross-sectional microscopy of the bonding interface indicates that the packages bonded with relatively low scanning speed and external pressure conditions have higher bonding quality. This research demonstrates the potential of localized laser bonding process for ceramic MEMS packaging.
