Abstract.
Precise positioning in indoor environments faces different challenges than the outdoor ones. While indoor environments are limited in size to rooms and buildings, outdoor positioning capabilities require regional or even global coverage. Secondly, the difficulty of receipting satellite signals indoors has triggered the development of high sensitive and AGNSS receivers “ with many issues remaining unsolved. Thirdly, the accuracy requirements are dissimilar between indoor and outdoor environments “ typic ....etc

A dense gas is defined as any gas whose density is greater than the density of the ambient air through which it is being dispersed. This result can be due to a gas with a molecular weight greater than that of air or a gas with a low temperature due to auto-refrigeration during release, or other processes. The importance of dense gas dispersion has been recognized for some time. Early field experiments (Van Ulden, 1974; Puttock et al., 1982; Koopman et al., 1984) have confirmed that the mechanisms of dense gas dispersion differ markedly from neu ....etc

ABSTRACT

This seminar Indoor Positioning and Navigation with Camera Phones discuss about low-cost indoor navigation system runs on off-the-shelf camera phones. The system uses built-in cameras to determine user location in real time by detecting unobtrusive fiduciary markers. The required infrastructure is limited to paper markers and static digital maps, and common devices are used, facilitating quick deployment in new environments. marker-based navigation is easier to use than conventional mobile digital maps. the users' location awarenes ....etc

This seminar deals about working of Indoor Positioning Systems (IPS) and the application of Indoor Positioning Systems (IPS) like patients under care or equipment in a hospital. Indoor Positioning Systems (IPS) locates and track objects in buildings. Most system apply wireless concepts or optical tracking, ultrasound, phase-shift system. commonly The located objects shall be tagged with labels, tags, tokens or transponders to enable locating or positioning.Global navigation satellite systems (GPS or GNSS) are not s ....etc

The Carpet Loop II is an ideal step upward for the listener who wants something better than a random wire but doesn't want the expensive dice roll of an active antenna.

The Carpet Loop is made up of two components: A tuner, and the antenna cable itself; the cable can be either 5-conductor rotator cable or 4-conductor flat phone cable, both readily available from Radio Shack and elsewhere. The tuner couples the antenna to the radio, forming a (giant!) L-network. To tune the antenna, you turn a switch for best reception.

While NO antenna c ....etc

Indoor Geolocation

Recently, there is an increasing interest in accurate location finding techniques and location based applications for indoor areas. The Global Positioning System (GPS) and wireless enhanced 911(E-911) services also address the issue of location finding. However, these technologies cannot provide accurate indoor geolocation, which has its own independent market and unique technical challenges.

Despite extraordinary advances in global positioning system (GPS) technology, millions of square meters of indoor space are out o ....etc

Abstract:
Knowledge of ambient optical noise is essential for designers of free space optical links, for resilient designs. In this paper, a complete experimental
characterisation of the most common ambient optical radiation is presented. The study includes Tungsten filamen t sources, low and high frequency
fluorescent lights, IR headphones, TV remote controls, and daylight. Means to reduce their influence on the performance of the links are also given.
The results are valuable towards setting a standard way of comparing wireless IR links, ....etc

Indoor Positioning
by Kalid Azad

1 Introduction
1.1 The Problem of Indoor Positioning
Currently, there is no commonly agreed-upon way to determine position indoors. In contrast, GPS (Global Positioning System) works well outdoors and is almost universally used. However, its signals are weak enough to be blocked by the walls of a building, and thus is not available for indoor applications. Various methods exist for indoor positioning, but all must balance flexibility, cost, and accuracy.

The ....etc
