  • The Transition from Video Motion Detection to Intelligent Scene Discrimination and Target Tracking in Automated Video Surveillance Systems
    Security Journal, 2002
    Co-Authors: Layne Hesse
    Abstract:

    Closed circuit television (CCTV) has been in use by security and law enforcement for the last three decades. The CCTV industry and CCTV technology has evolved into a rapidly growing and technologically advanced component of the security field. Video motion detection (VMD) is a software or combined hardware device used in conjunction with video-imaging devices to detect intrusion and to generate an Alarm Condition, as set by the parameters of the security system.

    Abstract:

    Closed circuit television (CCTV) has been in use by security and law enforcement for the last three decades. The CCTV industry and CCTV technology has evolved into a rapidly growing and technologically advanced component of the security field. Video motion detection (VMD) is a software or combined hardware device used in conjunction with video-imaging devices to detect intrusion and to generate an Alarm Condition, as set by the parameters of the security system. The growth in the use of CCTV for law enforcement, private security, proprietary security and military applications has boomed in recent years. This growth and advances in computing technology are providing CCTV users with faster, more accurate and automated functions for CCTV systems. Developments in VMD technology continue to enhance existing and new CCTV systems. New advances are facilitating the transition of VMD to intelligent automated video surveillance systems.

  • LCN – A real-time kernel for wireless sensor networks employed in rescue scenarios
    2009 IEEE 34th Conference on Local Computer Networks, 2009
    Co-Authors: Heiko Will, Kaspar Schleiser, Jochen Schiller
    Abstract:

    In rescue scenarios, real-time requirements are one key issue when using wireless sensor networks (WSNs) for tracking and monitoring of rescue forces. If a node detects an Alarm Condition, the Alarm message must be delivered to the base station in time. To guarantee the timely delivery the whole system architecture has to fulfill real-time requirements. There are only a few real-time architectures which can be used for sensor networks. These architectures are too generic to comply with the other requirements of a WSN architecture, like RAM usage and energy awareness.

  • Transmission/reflection analysis for localization of loss-inducing perturbations in distributed fiber optic sensor based on Rayleigh backscattering
    Advanced Sensor Systems and Applications, 2002
    Co-Authors: Vasilii V. Spirin, Francisco J. Mendieta-jimenez, Pieter L. Swart
    Abstract:

    We present a simple method for the localization of a loss region for a fiber-optic AlarmCondition sensor based on the measurement of transmitted and Rayleigh backscattered power. Bending the sensing fiber affects both the transmitted and backscattered power of unmodulated continuous-wave light that is launched into the fiber. The position of the loss region is determined from unique relationships between normalized transmitted and backscattered powers for different locations of the disturbance along the test fiber. The localization of a strong disturbance with an estimated accuracy of few meters along a few km-length single-mode test fiber was demonstrated.

  • AlarmCondition detection and localization using Rayleigh scattering for a fiber-optic bending sensor with an unmodulated light source
    Optics Communications, 2002
    Co-Authors: Vasilii V. Spirin, Mikhail G. Shlyagin, Serguei V Miridonov, Pieter L. Swart
    Abstract:

    We present a simple method for the localization of a bending loss region for a fiber-optic AlarmCondition sensor based on the measurement of transmitted and Rayleigh backscattered power. Bending the sensing fiber affects both the transmitted and backscattered power of unmodulated continuous-wave (CW) light that is launched into the fiber. The position of the loss region is determined from unique relationships between normalized transmitted and backscattered powers for different locations of the disturbance along the fiber. The localization of a strong disturbance with an accuracy of 1 m at positions near the source-end and of 5 m at positions near the remote-end of a 4.04 km length single-mode fiber was demonstrated.

  • Localization of a loss-inducing perturbation for a fiber optic AlarmCondition sensor using an un-modulated light source
    2002 15th Optical Fiber Sensors Conference Technical Digest. OFS 2002(Cat. No.02EX533), 1
    Co-Authors: Vasilii V. Spirin, Mikhail G. Shlyagin, Serguei V Miridonov, R.m. López, Ileana Marquez Borbon, Pieter L. Swart
    Abstract:

    We present a new method for localization of a loss region for a distributed fiber optic Alarm Condition sensor based on transmission/reflection analysis. We have demonstrated that the proposed sensor, based on Rayleigh scattering, allows for the localization of one loss-inducing perturbation along a sensing fiber by measuring only transmitted and Rayleigh backscattered powers of unmodulated CW (continuous wave) light. Localization of a strong disturbance with an accuracy of 1 m close to the source-end and 5 m close to the output-end of a 4.04 km long single-mode sensing fiber was demonstrated. We believe the proposed technique should be very attractive for the eventual realization of a compact and inexpensive distributed Alarm fiber optic sensor.

  • Real time portable telemedicine system for cardiac patient
    2009 International Conference on Future BioMedical Information Engineering (FBIE), 2009
    Co-Authors: V. Thulasi Bai
    Abstract:

    Available conventional methods of cardiac patient monitoring mostly perform offline analysis and restrict the mobility of the patients within a hospital or room. Even if an analysis is made, the results are recorded only on a server, where the doctor has to go and make the analysis and then initiate a treatment. This is patently time consuming. Hence, this work proposes a portable telemedicine system that monitors, performs real time analysis with the hand held device constructed using an ARM based microcontroller AT9263EJ-S. This handheld device acquires and analyses the ECG signals from the patient continuously. If the portable system detects any arrhythmia, it automatically sends an Alarm Condition to the patient’s care taker and physician on a mobile phone by sending an SMS. The system was tested successfully and success rate of getting the alerting SMS during peak network traffic time was also conducted.
