A first-of-its-kind rehab robot! NSF Science Now 34

The video covers four main studies: a University of Illinois study on teen driving behavior, showing reduced risky decisions when a parent is present; the development of Harmony, a robotic exoskeleton for rehabilitation by the University of Texas; Oregon State University's WIFO technology, which enhances Wi-Fi bandwidth using LED lights; and the University of Washington's Apnea App, a smartphone application for detecting sleep apnea at home. Each study highlights innovative approaches to improving safety, health, and technology.

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

• It has no effect on driving behavior.

• It decreases the likelihood of risky driving.

• It increases the likelihood of risky driving.

• It makes teens drive faster.

What is the primary purpose of the Harmony robotic exoskeleton?

• To assist in daily household chores.

• To provide physical therapy for neurological disorders.

• To enhance athletic performance.

• To improve military training.

What is the expected outcome of using Harmony for physical therapy?

• Increased therapy costs

• Longer recovery times

• No change in recovery times

• Reduced recovery times

How does WIFO technology improve Wi-Fi bandwidth?

• By using multiple antennas.

• By employing LED lights to transmit data.

• By increasing the number of routers.

• By reducing the number of connected devices.

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

• 50 megabytes per second

• 200 megabytes per second

• 100 megabytes per second

• 10 megabytes per second

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

• It provides instant treatment.

• It is non-invasive and can be used at home.

• It requires hospital visits.

• It is more expensive.

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

• Visual monitoring

• Inaudible sound waves

• Infrared sensors

• Temperature sensors
