On-road driving studies to understand why drivers behave as they do at regional rail level crossings [PDF]
, 2013 Improving safety at rail level crossings is an important part of both road and rail safety strategies. While low in number, crashes between vehicles and trains at level crossings are catastrophic events typically involving multiple fatalities and serious

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices
International Journal of Circuit Theory and Applications, EarlyView.A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented
