This paper presents a novel technique to eliminate non-simultaneous triggering e ects in nger-type ESD protection transistor using SiGe heterojunction buried layer structures. It is con rmed that lower snapback voltage and maximum lattice temperature are obtainable in the new structure based on device simulation. As a result, current localization and lattice overheating of a nger-type protectio...

In order to reduce or eliminate the consequences of the electronic equipment malfunction, some important electronic equipment were installed protection devices. Failures of protection devices are of hidden feature, and can only be found by inspections. Protection device failing to system malfunctioning has a delay characteristic. According to this delay characteristic, an inspection policy was ...

Electrostatic discharge (ESD) protection devices can have an adverse effect on the performance of high frequency and RF circuits. This work presents for the first time, an s-parameter based analysis of the performance of RF circuits with various ESD protection designs. Additionally, a design methodology for distributed ESD protection using coplanar waveguides is developed to achieve a better im...

The complexity of today's distributed computing environment is such that the presence of bugs and security holes is statistically unavoidable. A very promising approach to the present issue is to implement a self-protected system. Self-protection refers to the ability for a system to detect illegal behaviors. This article demonstrates the implementation of self-protection manager which targets ...

We describe how an open computing device can be extended to allow individual programs and operating systems to have exclusive access to cryptographic keys. This problem is of fundamental importance in areas such as virus protection, protection of servers from network attacks, network administration and copy protection. We seek a system that can be unconditionally robust against software attacks...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

Original scientific paper Memristors will surely have application in secondary lightning protection as well. This paper proposes a combined over-voltage protecting device consisting of a memristor connected in series with a spark gap. Operation of this combined device has been simulated with circuit simulation software on a model proposed in this paper. The memristor is applied for dissipating ...

We present the case of a 49-year-old woman with neurological symptoms and severe atherosclerosis of aortic arch branches affecting subclavian and carotid arteries. Our patient has a history of transient ischemic attack and recurrent paresthesias of her right arm. We present a double access intervention using a distal embolic neuroprotection device during ostial right subclavian artery recanaliz...

Schirmer Engineering Corporation (Schirmer Engineering) was retained by The Fire Protection Research Foundation (FPRF) as a Project Consultant for the project titled “Data Needs for NFPA Automatic Sprinkler Committees.” This report investigates the NFPA 13, Standard for the Installation of Sprinkler Systems (2007 Edition) requirements for dry pipe systems having a maximum volume of 500 gallons ...
