According to a list published by the United States Trademark and Patent Office (USPTO), Apple today acquired the rights to a technology involving the Apple Watch. Apple wants to introduce radar sensors in the Apple Watch to monitor human breathing and cardiovascular biometrics.
The radar system outlined in Apple’s patent has two components, a transmitter that emits signals to a target object and a receiver that receives reflected signals from the target object. The radar system can detect the movement or vibration of the target object based on the reflected signal.
The patent, the radar system can “refine” the displacement movement or vibration, and divided into:
- 0.5 mm and below
- 1 mm and below
- 2 mm and below
- 5 mm and below
- 1 cm and below
- 2cm and below
- 5 cm and below
The different “refinement” levels allow for the detection of the wearer’s breathing rate, heart rate, coughing, sneezing, trembling, seizures and/or other movements or vibrations of the body.
