Common Display System (CDS) at the NAVAIRWD Ranges

Karr, Bill, Maxel, Matt, Watson, Errol 10 1900 (has links)
ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Common Display System (CDS) will provide all NAVAIRWD sites with a flexible Range real-time situational awareness and telemetry display/processing capability. CDS will have an extensible framework enabling all sites to quickly and conveniently develop Range unique plugins to accommodate new requirements or functionality not presently found in the applications common core plug-ins. Range unique plug-ins are separate and distinct from the application's common core engine.

A Situational Awareness Enhancing System for Minimally Invasive Surgery Training

Feng, Chuan January 2007 (has links)
Minimally Invasive Surgery (MIS) is a surgical technique involving small incisions performed by an endoscope and several long, thin instruments. Because of its minimally invasive nature, MIS minimizes complications and speeds up recovery time compared to the traditional surgery. Unfortunately, from a surgeon's perspective, MIS is much more challenging than conventional surgery. Because the limited vision and sensing feedbacks, MIS a difficult skill for medical students and residents to master.There has been some research on the effectiveness of different kinds of training and guidance. Surgical simulation is increasingly perceived as a valuable addition to traditional medical training methods, although most existing simulators have limitations stemming from either a lack of objective performance assessment or an insufficient relation to the operating room reality.The objective of this research is to design and realize a novel prototype that advances the state of the art in surgical training, assessment, and guidance for MIS. The prototype features micro-sensors embedded into the instruments employed for simulation training. The system provides multiple training scenarios, a high fidelity training environment, repeatable, structured exercises, and objective performance assessment capabilities.The proposed Situational Awareness Enhancing System (SAES) uses a unified framework incorporating perception, comprehension, and projection software modules that provide feedback during the exercises and enable evaluation of the training procedure.A multiple sensor data fusion method was developed to help surgeons efficiently acquire information in real time. The output, "Hybridview", is produced by fusing the information from digital camera and magnetic position sensors, and shows an overlay of the positions of organs and objects with the trajectory of instruments. An intelligent inference engine was designed to formulate an objective standard based on the expertise of senior surgeons and to provide an accurate scoring method. A multi-level fuzzy inference engine and new performance metrics were implemented.To demonstrate the feasibility of the proposed training system, numerous experiments were conducted. The results show that the situational awareness training system for MIS is useful and efficient.

Operation of long-haul non-LOS wireless tactical networks

Zachariadis, Christoforos P. 03 1900 (has links)
The IEEE 802.16-2004 wireless standard is a robust, wireless, longhaul solution for connecting remotely located, forward operating bases. Proof of concept for this capability is the NPS OFDM testbed for the research and support of the communications and collaborative processes between tactical operators within a wireless network. This thesis will attempt to develop strategies for implementing network management, establish a performance baseline for the NPS testbed and define the acceptable metrics for QoS. Field experimentation scenarios, network performance management tools and modeling tools are the techniques that we are using to assess the operation of 802.16 NPS testbed for its quality requirements. A baseline is conducted to record the state of the network operation and investigate the operational guidelines and conditions for the network to support collaborative applications. The baseline provides good organization, status monitoring and planning capabilities that will help in troubleshooting future failures. Using OPNET Modeler ACE we examine the network traffic flow and diagnose performance issues for critical applications. Finally, we develop appropriate policies to fine-tune network behavior within a holistic ad hoc collaborative environment.
