Opportunistic Sensing with Recreational Hot-Air Balloon Flights

Hot-air balloon explosion in the heart.

A 16-year old girl experiencing palpitations underwent elective transthoracic echocardiographic examination at a nearby clinic, which showed a 3-cm balloon-like, cystic structure, with inhomogeneous content, adherent to the atrial septum and anchored above the anteroseptal commissure of the tricuspid valve without evidence of flow from the aorta to the right atrium (Figure 1 A). On examination,...

Factors associated with fatalities and injuries from hot-air balloon crashes.

CONTEXT Despite the increased popularity of hot-air balloon flight, data on injuries and fatalities associated with hot-air balloon crashes are limited. OBJECTIVE To determine factors associated with injury and death in hot-air balloon crashes. DESIGN Retrospective review of data collected from reports and investigations by the Civil Aeronautics Board and the National Transportation Safety ...

Goal Oriented Opportunistic Sensing

Today’s activity and context recognition system have the drawback to use a static sensing infrastructure that has to be defined at the design time of the system. The predefined sensing infrastructure needed to work properly, as well as the fixed recognition purpose limits the flexibility of such a system as it can’t react on changes in the sensing infrastructure nor it can address a change in i...

Hot-air balloon tours: crash epidemiology in the United States, 2000-2011.

INTRODUCTION Hot-air balloon tours are FAR Part 91-governed balloon rides conducted for compensation or hire. Part 91, General Aviation, in general involves the least strict federal regulations and accounts for the majority of aviation crashes and fatalities. METHODS National Transportation Safety Board reports of hot-air balloon tour crashes in the United States from 2000 through 2011 were r...
