OptiMon: Reliable wireless monitoring for industry

Condition and energy monitoring of industrial assets by means of sensor systems has become widespread in recent years. Current systems are mostly wired, and thus installation can be difficult, inflexible, and costly. In addition, wired condition monitoring is not feasible in some cases (e.g., with moving parts), and harsh environments pose a threat for present technologies (vulnerable cables and connectors). Wireless condition monitoring is flexible but has challenges with respect…

Communication manager for disaster management

The wireless standard for emergency services used by first responder organizations—TETRA (Terrestrial Trunked Radio)—provides robust and secure communication but offers limited data rates unsuited for multimedia data. Such multimedia data, however, would be beneficial in complex emergency situations. For example, in case of a large event, the police needs to keep an overview of various locations to monitor incidents (e.g., violence or mass panic). Real-time reports need to be available…

Communication demands of drone applications

Small drones become increasingly popular for civil applications, including production of movies and delivery of important goods. The wireless communications and networking of drones is an essential building block in such systems. Lakeside Labs researchers have been working in this domain for several years; now they wrote a comprehensive survey article on the characteristics and requirements of drone networks. Evsen Yanmaz, senior researcher and project manager, states: “Our survey quantifies…

UWB sensor networks in airplanes

Modern airplanes are equipped with hundreds of embedded sensors and actuators necessary for structural health monitoring, aircraft control, and passenger and crew assistance. These devices are typically interconnected by wires. Using wireless connections instead of wires improves flexibility of installations and reduces the airplane’s weight. Researchers from Airbus Group Innovations have been working on this topic for several years. An ongoing joint project with the University of Klagenfurt and Lakeside…

Research days on multi-UAV systems

The Sixth Research Days of Lakeside Labs und U Klagenfurt from July 8 — 12, 2013, hosted invited experts, professors, and young researchers to discuss ideas and exchange experiences on systems with multiple unmanned aerial vehicles (UAVs). Autonomous UAVs are used with increasing interest in civil and commercial applications and by the scientific research community. Recently, research and development efforts have shifted toward using teams of UAVs for monitoring, surveillance,…
