In modern society, people increasingly lack social interaction, even though it is beneficial to professional and personal life. <i>Airhockey Over a Distance</i> aims to work against this trend by recreating the social experience and rapport facilitated by physical, casual game play in a distributed environment. We networked two airhockey tables and(More)
Variation in the assessment of basic clinical data gathered by emergency medical technicians and emergency department nurses was studied. Prior to testing, precise definitions, categories and procedures were developed and tolerance limits for the quantitative variables were created. Each participant evaluated four consecutive patients simultaneously with(More)
This paper proposes the use of optical flow from a moving robot to provide force feedback to an operator’s joystick to facilitate collision free teleoperation. Optical flow is measured by a pair of wide angle cameras on board the vehicle and used to generate a virtual environmental force that is reflected to the user through the joystick, as well as feeding(More)
In modern society, people increasingly lack social interaction, although beneficial to work and personal life. Airhockey Over a Distance addresses this issue by recreating the social experience facilitated by physical game play in a distributed environment. We networked two airhockey tables and augmented them with a videoconference. Concealed mechanics on(More)
Algorithms for the prehospital management of cardiac arrhythmias were developed and their use by and value to paramedics evaluated. The algorithms, in booklet form, were distributed to half of the Philadelphia paramedic platoons; paramedics in the other platoons followed a narrative protocol that reflected identical contents. An arrhythmia recognition test(More)
Insect behaviour has been a rich source of inspiration for the field of robotics as the perception and navigation problems encountered by autonomous robots are faced also by insects. In this paper, we introduce a research platform, the Insectbot, that was built as a testbed for new biologically-inspired, vision-based algorithms and systems. The Insectbot is(More)
A methodology for evaluating the quality of emergency department care in the form of a retrospective process audit for emergent and urgent cases was developed and tested in the Philadelphia General Hospital Emergency Department. A physician panel develped criteria against which the management of six "chief complaints," as indicated on the medical record,(More)
