Biometric monitoring device with immersion sensor and swim stroke detection and related methods

This is a wearable device for your forearm that tracks swimming activity. It uses motion sensors, like a gyroscope, to detect swim strokes and laps, and an immersion sensor, such as a barometric altimeter or galvanic skin response sensor, to determine if it's in water. The device can then provide audio or vibration notifications.

Why it matters: Filed before advanced sensor fusion and on-device machine learning. These now simplify accurate stroke detection.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateSensors, electronics, software for motion and immersion.
