Radar and the REST Bedside Device

The word “radar” might call to mind those dish-shaped antennas that receive or transmit satellite signals via radio waves or maybe the powerful marine radar that fishermen use to detect schools of fish. But more and more, radar is used for everyday technologies to improve our quality of life.

Full Sleep uses a small bedside companion called REST (Radar-Enabled Sensing Technology) to collect sleep data and guide you through the program. Using radar sensing, REST picks up your movements, temperature, and sound, keeping tabs on your sleep cycles and times awake. 

When it’s time to get to sleep, REST guides you through wind down and relaxation techniques. In keeping with the CBT-I principles that empower the Full Sleep program, the REST device alerts you when you’ve been lying in bed awake for too long, encouraging you to get up until your body feels ready to sleep. 

Because REST is not a wearable device, it won’t make you uncomfortable or conflict with your sleep. Instead, REST uses non-invasive radar to accurately, safely, and reliably gather data that gives you an in-depth picture of how you sleep. The elegant design helps it maintain a low profile on your nightstand until you need it. 

What is radar technology? 

The term radar stands for “radio detection and ranging.” Radar operates by transmitting radio frequency (RF) energy, and then measuring the energy that’s reflected back to the receiver. 

The word “radar” might call to mind those dish-shaped antennas that receive or transmit satellite signals via radio waves or maybe the powerful marine radar that fishermen use to detect schools of fish. But more and more, radar is used for everyday technologies to improve our quality of life. Radar sensors are exceedingly helpful for smart devices for several reasons:

  • Size: They have a small footprint and can be used on a number of devices. For instance, radar technology is integrated into smartphones to read hand gestures. 
  • Dependability: Radar sensing technology isn’t reliant on optimal conditions. The data is reliable regardless of variations in temperature or lighting.
  • Sensitivity: Radar can pick up the slightest motions. That’s why it can detect changes in breathing or heartbeats. 
  • Efficiency: Very little power is consumed by radar, so it doesn’t place a significant drain on battery life. 
  • Safety: Radar is more reliable than other sensor technologies and because the radio frequencies transmitted and received by radar are not harmful, it’s completely safe for humans and animals. 

Common radar applications

Radar technology has greatly improved the functionality of many smart devices. While you may not realize it, you’re likely already interacting with at least one radar-enabled device on a daily basis.The accuracy and low energy consumption of radar sensors makes them useful in many fields and applications. . 

Smart car technology

Radar has become an integral part of newer cars. With radar, they let us know when someone is in our blindspot. They assist us in parking. They lift the hatchback when our hands are full of groceries. Going forward, radar will play a considerable role in autonomous vehicle designs allowing vehicles to recognize other drivers and obstacles.

Elder care

Radar-empowered devices are often used to alert nursing staff if someone falls, gets out of bed without returning, or remains in their chair for too long.  

Home security

Radar allows video doorbells to gather info using ultra-precise detection of people coming toward it, so non-specific movements from traffic or pedestrians don’t trigger it. It also allows you to collect sensitive information without being too invasive. For instance, an Airbnb host could see how many people are in a room without actually seeing them, allowing them to monitor their space for unsanctioned parties without invading anyone’s privacy. 

Energy efficiency 

Radar sensors can determine if someone isn’t in a room after some time, and respond accordingly, turning off lights, putting electronics to sleep, turning off dangerous appliances like stovetops, or adjusting the thermostat. 

Medical devices

Soon people with various conditions will rely on radar sensing technology to keep them safe. For example, this technology can detect deviations in heartbeats or respiratory problems and issue the appropriate alerts. 

Radar is already playing a big role in our everyday lives. And the advantages that come with it—form factor, dependability, sensitivity, efficiency, and safety—also make it the best option for tracking sleep in the home. 

Safety of radar technology in the REST device 

Radar technology used by devices like REST is perfectly safe for use in the home.

Radar emits a form of RF (radio frequency) radiation. The word “radiation” may sound concerning (largely thanks to its use in entertainment media), but it is simply the emission or transmission of energy in the form of waves or particles. The spectrum for radiation goes from extremely low-energy (frequency) to high-energy (frequency). This is called the electromagnetic spectrum. 

Unlike x-rays and gamma rays, radiofrequency (RF) radiation exists at the lower end of the electromagnetic spectrum. It’s a type of non-ionizing radiation, meaning that it doesn’t have enough energy to separate electrons from an atom. We’re surrounded by this kind of electromagnetic energy all the time. It makes up visible light and is part of earth’s natural field that makes a compass point north.

Since the creation of the radio and television, we’ve been surrounded by man-made sources of RF radiation as well. Consumer products like computers, smartphones, and products relying on radar technology (like REST) operate on this low-energy, non-ionizing area of the electromagnetic spectrum. 

The Federal Communications Commission (FCC) closely regulates radiofrequency devices used in electronic products capable of emitting RF energy by radiation, conduction, or other means. And the frequency/power range allowed by consumer products like security cameras or the REST device ensures that the signal is partly reflected and partly absorbed by the moisture of our skin, unable to penetrate deeper. 

As it explains on the FDA website, “Scientific consensus shows that non-ionizing radiation is not a carcinogen and, at or below the radio frequency exposure limits set by the FCC, non-ionizing radiation has not been shown to cause any harm to people.”

The bedside REST device

The REST device sets Full Sleep apart from competitors. Radar is used to monitor your heart rate and breathing, sensing when you’re awake or asleep.This information is used to track your sleep patterns and the times you’re awake and provide real-time guidance when you need it. 

With radar, REST can capture far more accurate data than a phone or other device placed under your pillow, in a much less intrusive manner than a wearable device. When coupled with the Full Sleep app and one-on-one coaching, REST gives you the guidance and insights you need to address serious sleep issues.
