Intelligent boarding to ski lifts

A novel boarding solution for cabin-based transport systems — e.g., ski lifts, cable cars, subways — is being discussed in industry and has already been implemented in the Austrian skiing resort Bad Gastein: In order to avoid long queues at succeeding boarding stations, a display in the boarding area tells the guests how many of them are allowed to enter the next cabin. This form of access control guarantees spare…

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…

A year in the life of Lakeside Labs

By Christian Bettstetter, Scientific Director Did you observe that lately more and more tech products and business processes have features of self-organization? Almost every major car maker has been testing self-driving vehicles and is now introducing them to the market. The industry is crazy about “industry 4.0”—which promises self-organizing production with humans, machines, and products collaborating to make decentralized decisions. These are just two examples for the ongoing trend toward…

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…

Austrian robotics workshop

About 80 researchers from industry and academia met at the Austrian Robotics Workshop in Klagenfurt on May 7 and 8, 2015, giving talks and demonstrations on recent developments in robotics and autonomous systems. Among them, various Lakeside Labs scientists presented their research in unmanned aerial vehicle systems, namely on wireless communications, collision avoidance, path planning, and video streaming. Two highlights were keynote talks given by invited experts: Sabine Hauert from…

Achieving consensus in networks with disturbances

The problem of finding a consensus in a group of people occurs in many social contexts. In a similar way, distributed algorithms for consensus play an important role in networked computing and communication systems if centralized decision making is difficult or impossible. Each entity in such a system processes only local information obtained from its neighbors and ideally performs only simple computations. Despite this simplicity, the process of consensus building…
