For years, emergency medical service providers conducted patient care by manually measuring vital signs, documenting assessments on paper, and communicating over handheld radios. When disasters occurred, the large numbers of casualties quickly and easily overwhelmed the responders. Collaboration with EMS and hospitals in the Baltimore Washington Metropolitan region prompted us to develop miTag (medical information tag), a cost- effective wireless sensor platform that automatically track patients throughout each step of the disaster response process, from disaster scenes, to ambulances, to hospitals. The miTag is a highly extensible platform that supports a variety of sensor add-ons - GPS, pulse oximetry, blood pressure, temperature, ECG - and relays data over a self-organizing wireless mesh network Scalability is the distinguishing characteristic of miTag: its wireless network scales across a wide range of network densities, from sparse hospital network deployments to very densely populated mass casualty sites. The miTag system is out-of-the-box operational and includes the following key technologies: 1) cost-effective sensor hardware, 2) self-organizing wireless network and 3) scalable server software that analyzes sensor data and delivers real-time updates to handheld devices and web portals. The system has evolved through multiple iterations of development and pilot deployments to become an effective patient monitoring solution. A pilot conducted with the Department of Homeland Security indicates miTags can increase the patient care capacity of responders in the field A pilot at Washington Hospital showed miTags are capable of reliably transmitting data inside radio-interference-rich critical care settings.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127105292","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}

A special attention is paid to the ion mobility spectrometry, its improved version, field compensated ion mobility spectrometry (known also as FIS, FAIMS, microDMxtrade, and DMS), and mass spectrometry. Sampling and analysis scenarios are discussed with special emphasis on the ways to prevent positive and negative false alarms, like through 'doping', for example. Possible explanations of false negatives and ways of their prevention as well as the detection of well hidden explosives are discussed. Reasons for the X-ray screening being the primary and the trace chemical detection-the secondary screening methodology at airports are explained. Sampling; pyrolysis/ volatilization of sample; transfer of volatilized sample, and its ionization; transfer of ions, their separation, and detection are discussed, and the ways of improvement proposed. Advantages and disadvantages of multipeak detection are presented. A comeback of mass spectrometry is observed with instruments being miniaturized and equipped with innovative ionization sources which should make sampling easier and detection more specific. Importance of the miniaturization of the transportation security instrumentation is stressed. A confirmational analysis is suggested as another important tool in the prevention of false negatives and positives, especially when the multipeak detection is not possible. A new detection system, consisting of the miniaturized FAIMS and mass spectrometer is proposed as the sensitive, specific, portable and rapid response trace chemical detection system for Homeland Security applications.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123778370","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}

For government and military applications, it is crucial to conduct effective and efficient testing of security properties for newly developed systems, which are to be integrated into existing information system. Yet little progress has been made in the technology advancement of rigorous and automated security testing. In this contribution we present virtual cyber security testing capability (VCSTC) - a DoD funded project-for developing an automated testing capability that can assess the operational functions and security impact of a target system without physically integrating it into an intended network infrastructure. VCSTC first synthesizes a model to emulate the real network infrastructure; then it automatically generates and executes test cases with guaranteed coverage of the features and security properties under test. This report presents the architecture of VCSTC, its key techniques and experimental results on real systems.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126394406","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}

Determination of the detector's energy calibration using one or more known radioisotopes is generally required for all applications. We are developing an algorithm that automatically finds the best energy calibration using one or more identified (standard) gamma spectra as input, with no effort on the part of the user other than qualitatively identifying the isotopes present in the spectrum. Instruments that suffer significant energy calibration drift, such as Nal handheld identifiers, also require some type of real time gain stabilization to keep their calibration steady. We have developed two approaches for stabilizing the energy calibration for MIMBS analyses, (1) a standard peak-based gain stabilization algorithm for use when seeded or background gamma peaks are known to be present and (2) a peak-free stabilization algorithm based on a non-linear gain optimization. In this report, we describe the calibration algorithms and evaluate their effectiveness on real and simulated gamma-ray spectra under varying measurement conditions.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133992048","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}
