Patent attributes
The arm motion sensor system includes at least one sensor attached to the body and positioned to detect arm motions, a control system for detecting when the arm motion is characteristic of a bad habit or activity that may spread infectious disease, and an alert system warning the user to refrain from such activity. In one embodiment, the sensor attached to the wrist and includes a 3-degree of freedom, 9-axis inertial measurement unit and an Edge TPU (Tensor Processing Unit). The wrist sensor communicates with a control system in the Cloud that includes an Artificial Intelligence (AI) unit that is trained to recognize undesirable motions. The wrist sensor includes an alarm system (tactile, auditory, or visual that warns the user to refrain from undesirable arm movements. Optionally, this system may also include an infrared sensor and WiFi MCU (microcontroller unit) positioned near the neck to screen out acceptable arm movements.
