Passive Millimeter-Wave


Passive millimeter-wave (PMMW) imaging is a method of forming images through the passive detection of naturally occurring millimeter-wave radiation from a scene. Although such imaging has been performed for decades (or more, if one includes microwave radiometric imaging), new sensor technology in the millimeter-wave regime has enabled the generation of PMMW imaging at video rates and has renewed interest in this area. This interest is, in part, driven by the ability to for ....etc

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc

ABSTRACT
Time and again the Formula 1 world has proved that the safest place on earth is inside an F1 car. The number one cause of racing related fatalities was the basilar skull fractures from excessive head motions and neck loading. With the introduction of the new Head And Neck Support (HANS) the drivers were able to overcome the only window for injury.
The fundamental purpose of the system is to effectively form a single Ëœbodyâ„¢ of the head and torso. HANS is intended to prevent driverâ„¢s head from being thr ....etc

Passive solar heating and cooling represents an important strategy for displacing traditional energy sources in buildings. Passive solar techniques make use of the steady supply of solar energy by means of building designs that carefully balance their energy requirements with the building's site and window orientation. The term passive indicates that no additional mechanical equipment is used, other than the normal building elements. In this approach, the building itself or some element of it takes advantage of natural energy characteristics in ....etc

INTRODUCTION

Miniaturization has been a key contributor to advances in electronic technology. Certainly, miniaturization has been made possible mostly through remarkable breakthroughs in reducing the size of active components. But as integrated circuits get smaller and more complex, there is an increasing need to also reduce the space required for the supporting passive components. If any of the electronic devices such as cellphone, camcorder, computer, or other consumer electronics system is opened, one or two circuit boards on which are mo ....etc

1. Abstract
The second harmonic inrush restraint function of transformerdifferential relays maintains security of the differential protectionduring transformer inrush events. The typical setpoint for thesecond harmonic restraint is the relay manufacturer’s defaultor recommended setting of 20% of fundamental current, withsome adjustment based on operating experience. However,some operating situations may result in levels of secondharmonic current lower than 20% during inrush, and levels maybe as low as 5%. This lower level of second h ....etc

Ethernet passive optical networks (EPON) are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site. EPONs build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PONs (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
The communications industry is on the cusp of a revolut ....etc
