Meet HARMONY-a first-of-its-kind rehab robot-NSF Science Now 34

The video covers four innovative studies: a University of Illinois study on teen driving behavior influenced by parental presence, a robotic exoskeleton called Harmony for rehabilitation developed by the University of Texas, a new Wi-Fi technology called WIFO from Oregon State University that uses LED lights to enhance bandwidth, and a smartphone app from the University of Washington for detecting sleep apnea at home. Each project is funded by the National Science Foundation and aims to improve safety, health, or technology efficiency.

What effect does a mother's presence have on a teen's driving behavior according to the study?

• Has no effect on driving behavior

• Encourages faster driving

• Decreases risky driving decisions

• Increases risky driving decisions

What percentage of risky driving choices did teens make when alone, according to the study?

• 55%

• 75%

• 45%

• 65%

What is the primary purpose of the Harmony robotic exoskeleton?

• To assist in daily activities

• To provide physical therapy for neurological disorders

• To enhance athletic performance

• To improve cognitive functions

How does WIFO technology improve Wi-Fi bandwidth?

• By compressing data packets

• By utilizing LED lights to create data cones

• By using multiple antennas

• By increasing the number of routers

What is the potential data transmission speed of the WIFO system per user?

• 50 megabytes per second

• 10 megabytes per second

• 200 megabytes per second

• 100 megabytes per second

What is the main advantage of the Apnea App over traditional sleep apnea testing methods?

• It is noninvasive and can be used at home

• It provides instant treatment

• It is more expensive

• It requires hospital visits

What method does the Apnea App use to detect breathing patterns?

• Electromagnetic fields

• Inaudible sound waves

• Infrared sensors
