Frequently Asked Engineering Questions
Essential answers on on-skin neural compute, biopotential vector capture, and hardware fail-safes.
Operating across a 75 mm modified Lead II dipole captures primary depolarization (P-QRS-T) to quantify AFib burden, syncopal events, and post-ablation arrhythmias. When repolarization anomalies or wide-complex tachycardias are detected, the cloud workstation flags the record to order a confirmatory 12-lead ECG. Furthermore, the onboard TI ADS1293 incorporates expansion pads to accept a snap-on 3-lead satellite harness for inpatient multi-vector monitoring.
A dedicated 128 MHz application core runs continuous 2.0-second inference windows in under 18 ms for real-time QRS detection and arrhythmia triage, while an isolated 64 MHz network core handles BLE 5.2 streaming. The model footprint is under 65 KB Flash and 16 KB SRAM, allowing the device to spend >98% of its duty cycle in ultra-low-power sleep.
High-speed TVS diodes and dielectric isolation clamp external spikes within nanoseconds, shunting high voltage away from sensitive AFE silicon, preventing skin burns under electrodes, and resuming baseline ECG tracking immediately post-shock.
Upon phone reconnection, high-speed 2M PHY burst resynchronization flushes critical Tier 1 telemetry first with cryptographic HMAC-SHA256 verification before clearing locks.
