As a result of the unpredictable nature extreme environments (including temperature, humidity, impact, and other factors), micro-electro-mechanical systems (MEMS) solid-state fuze control modules have an urgent requirement for MEMS switch (MEMS-S3). In particular, this must remain stable without any energy input after state transition (i.e., it be bistable). paper, bistable (MEMS-bS3) is design...

Fingerprint enhancement algorithm is used to improve the clarity of ridges and valleys of input fingerprint images. These kind of algorithm make them more suitable for the minutiae extraction algorithm. The ultimate criterion for evaluating such an enhancement algorithm is the total amount of “quality” improvement when the algorithm is applied to the noisy input fingerprint images. There are va...

MEMS varactors are one of the important passive MEMS devices. Their applications include use in VCOs, tunable impedance matching networks, tunable filters, phase shifters, and true time delay lines. The shunt capacitive structure has been employed in most of the conventional MEMS varactor designs because of its simplicity. However, the capacitance ratio of this conventional shunt capacitive MEM...

ABB Automation is starting to experiment with Microelectrical Mechanical Systems (MEMS) as an enabling technology for their products. If ABB's implementation of MEMS is found successful, it will be able to create breakhrough products and services that will revolutionize the market in ABB's industrial sensors, instrumentation and analytical areas. The thesis begins with a description of ABB as a...

Zero-level packaging technology ensures dicing and handling compatibility of the MEMS device along with low cost by encapsulating the MEMS components using wafer level processing. It is also essential for providing the MEMS with a controlled ambient in a cost-effective way. In order to be compatible with a broad range of MEMS processes, IMEC developed sealing methods with a low temperature budg...

Existing fingerprint segmentation methods usually process fingerprint images captured by different sensors with the same feature or feature set. We propose to improve the fingerprint segmentation result in view of an important fact that images from different sensors have different characteristics for segmentation. Feature usability evaluation, which means to evaluate the usability of features t...

micro-electro-mechanical systems (mems) are combination of electrical and mechanical components in micron dimensions. in recent years, holding, actuating methods and handling of mems components such asmicrogripper, microsensors and etc. have been deeply studied. microgrippers for handling, positioning andassembling of micro components are very useful so that for clamping need actuation created ...

Fingerprint recognition technology has been widely used in criminal investigation, attendance system, security testing and other fields and has become one of the most mature biometric technologies. Since fingerprint image quality affects heavily the performance of fingerprint recognition system, accurate evaluation of fingerprint image quality has great value in improving the performance of aut...

Automated fingerprint identification system has an increasingly important role in modern times. This study presents the steps of the automated fingerprint identification system and presents an application for fingerprint identification and system's equal error rate evaluation. The algorithm for fingerprint image enhancement is a key element of the system. A fingerprint image can be damaged, dam...
