The network of spin oscillators can have only local, cellular interconnections because of the underlying physics: the interaction between the oscillators happens through the magnetic field. In this paper we describe the dynamics of weakly coupled spin-torque oscillator networks and how the dynamics of these cellular arrays can be used for problem solving. We will describe how the phase shift in a synchronized array can be calculated between the elements and we will also show a simple example how the dynamics of a cellular array can be used to solve simple tasks.","PeriodicalId":387536,"journal":{"name":"2012 13th International Workshop on Cellular Nanoscale Networks and their Applications","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114276240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The infrared information of the surrounding area are used mainly for two different purposes: Navigation and Search & Track-While-Scan. Navigation functions, commonly identified with the name of Imaging Modes, are devoted to aid pilots in conjunction with advanced human machine interfaces such as Head Up Display (HUD) and Helmet Mounted Display (HMD). The availability of IR images generated from airborne opto-electronics equipment can support the pilot during navigation in adverse weather conditions, providing important information about external threats (i.e. obstacles), otherwise not detectable by human eye. Search & Track-While-Scan, is a functionality related to surveillance. It includes combination of automatic detection and tracking functions within a wide search volume. These features are typically executed in automatic way and generate the position of possible threats present in the flight path. In general Search & Track-While-Scan outputs are not displayed together with the IR image because the main purpose is to provide the estimated positions of the detected targets; nevertheless, if the Imaging Modes and Tracking capabilities are operated simultaneously in an integrated framework, the overall scenario representation can be improved and the situation awareness increased. This paper will focus on the airborne navigation by means of Infrared Sensors by considering the benefits but also possible limits and areas of improvements.","PeriodicalId":387536,"journal":{"name":"2012 13th International Workshop on Cellular Nanoscale Networks and their Applications","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116593173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
