Challenges of passive infrared indoor localization

2008 5th Workshop on Positioning, Navigation and Communication, 2008
In this paper a new approach for locating people indoors is proposed. Since location based services become relevant for an increasing number of people, e. g. the location dependent automatic control of lighting, there is a need for unobtrusive and easy to use location systems.

Device-Free Passive Localization based on Narrowband Channel Impulse Responses

International Radar Symposium, 2020
Device-Free Passive Localization (DFPL) is capable of detecting and locating an object without requiring the object to hold any device, nor to participate actively in the localization process.

QoI for passive acoustic gunfire localization

2008 5th IEEE International Conference on Mobile Ad Hoc and Sensor Systems, 2008
A network of acoustic arrays can localize a shooter. Each array can determine the direction of arrival (DOA) of the muzzle blast. Some arrays can also see the shockwave generated by the bullet as it travels at supersonic speeds. These arrays can also estimate the range to the shooter as a nonlinear function of the DOA and time difference of arrival ...

Passivation and Localized Corrosion

1991
A review is made of the main models proposed for the passive state, and also for the breakdown of passivity leading to localized forms of corrosion like pitting and crevice corrosion. Some particular aspects of crevice corrosion are analysed and the use of electrochemical techniques for its study is illustrated, like potential and current monitoring ...

Passivity and localized corrosion

Anti-Corrosion Manual, 1988
Passivity and localized corrosion is discussed using iron, iron-chromium, iron-chromium-nickel alloys and aluminium as examples. A brief description is given of the prevailing ideas regarding the nature of the passive film and the processes by which its protective properties are lost when breakdown of passivity and localized corrosion occurs.
