Definition
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 form images during the day or night; in clear weather or in low- ....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

The solar house: passive heating and cooling


ABSTRACT:

Passive solar heating and passive cooling—approaches known as natural conditioning—provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved.

Abstract
A Gigabit Ethernet passive optical network (GE-PON)
The GE-PON includes an optical line terminal (OLT), a plurality of optical couplers, and a plurality of optical network units (ONUs). The OLT sets up an active page link and a standby page link in response to a registration request message received over an optical cable. Each of the ONUs is doubly connected with the OLT via the optical cable and is adapted to transmit the registration request message to the OLT, form the active page link with the OLT via the optical cable if it re ....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

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
