با پیشرفت و همگانی شدن کامپیوترها، نیاز برای انتقال داده به کامپیوترها افزایش پیدا کرد. پورت ها وسیله ای برای ارتباط با device های جانبی متنوع از جمله کیبورد، میکروفون و ... هستند. با گذشت زمان پورتها به منظور پشتیبانی از گستره وسیعی از device ها، پیشرفته تر و کابردی تر شدند. با روی کار آمدن پورت usb دراواسط دهه 1990، این پورت توانست جایگزین سایر پورت های موجود شود چراکه این پورت ها به تنوع نا...

A substrate-triggered technique is proposed to improve electrostatic discharge (ESD) protection efficiency of ESD protection circuits without extra salicide blocking and ESD-implantation process modifications in a salicided shallow-trench-isolation CMOS process. By using the layout technique, the whole ESD protection circuit can be merged into a compact device structure to enhance the substrate...

Co-design strategy with low-capacitance (low-C) consideration for on-chip ESD protection in RF ICs is a solution to mitigate RF performance degradations caused by ESD protection device. A low-C design on ESD protection device was presented in this paper. An RF power amplifier (PA) codesigned with the low-C ESD protection device was also presented in this paper. Before ESD stress, RF performance...

The rapid growth in mobile technology makes the delivery of healthcare data and services on mobile phones a reality. However, the healthcare data is very sensitive and has to be protected against unauthorized access. While most of the development work on security of mobile healthcare today focuses on the data encryption and secure authentication in remote servers, protection of data on the mobi...

OBJECTIVE To report the feasibility, safety, and 1-month results of performing stent placement for vertebral origin stenosis with the use of a distal protection device. Distal protection devices have been shown to reduce the number of cerebral emboli and subsequent ischemic events when used as adjuncts to percutaneous carotid intervention; however, one case of the use of a distal protection dev...

We propose an input protection scheme composed of thyristor devices only without using a clamp NMOS device in order to minimize the area consumed by a pad structure in CMOS RF ICs. For this purpose, we suggest low-voltage triggering thyristor protection device structures assuming usage of standard CMOS processes, and attempt an in-depth comparison study with a conventional thyristor protection ...

BACKGROUND Stents provide effective treatment for stenotic saphenous venous aorto-coronary bypass grafts, but their placement carries a 20% incidence of procedure-related complications, which potentially are related to the distal embolization of atherosclerotic debris. We report the first multicenter randomized trial to evaluate use of a distal embolic protection device during stenting of such ...

AIMS Adjunctive thrombectomy and embolic protection devices in acute myocardial infarction have been extensively studied, although outcomes have mainly focused on surrogate markers of reperfusion. Therefore, the effect of adjunctive devices on clinical outcomes is unknown. This study sought to determine whether the use of a thrombectomy or embolic protection device during revascularization for ...
