Abstract: A system includes an input to receive at least one electrophysiological signal representing cardiac electrical activity measured from a body surface of a patient. The system also includes a signal processor to analyze the at least one electrophysiological signal and compute a score having a value to indicate a likelihood of arrhythmogenic activity, the score being computed as a function of at least two of cycle length, amplitude and polarity of the at least one signal.

Abstract: Methods and systems for detecting a medical emergency related to the driver of a vehicle are described. Various data, such as in-situ biophysical data of the driver, a medical history of the driver, and in-situ motion data of the vehicle, are employed to determine a possible medical emergency. In an event that a medical emergency is detected, the system determines the severity of the emergency and takes appropriate control of the vehicle. If the medical emergency is not life-threatening, the system may drive the vehicle to a safe area, park the vehicle, and then request help from emergency service providers (e.g., ambulance and police). If the medical emergency is severe (e.g., life-threatening), the system may transition the vehicle to an EMS (Emergency Medical Service)-privileged vehicle and autonomously drive the vehicle to an emergency service provider.

Abstract: An alcohol consumption determination method includes detecting a plurality of effective frames of an input voice signal; detecting a difference in signal of within the original signal of each of the effective frames; detecting average energy of the original signal and average energy of the difference signal for each of the effective frames; and determining whether alcohol has been consumed based on a difference between the average energy of the original signal and the average energy of the difference between the signals for each effective frame. Accordingly, it is also possible to determine, from a remote location, whether a driver or an operator remote has consumed alcohol and the degree of inebriation by using a difference signal energy method using a voice signal, thus preventing an accident caused by a operation vehicles and machines under the influence of alcohol.

Abstract: A method of alerting a vehicle's driver. The method comprises receiving an azimuth value indicating a gazing direction of a head of the driver from a primary device placed on the driver, receiving a vehicle bearing value indicating a vehicle moving direction of the vehicle driven by the driver, calculating an angular difference between the azimuth value and the vehicle bearing value, generating an alert when the angular difference deviates from an angular threshold, and automatically presenting the alert to the driver in response to the angular difference.
