A driving assistance system and a driving assistance method are provided. The driving assistance system includes a physiological information sensing system, an external physical symptom detection system, and a processing device. The physiological information sensing system is configured to sense physiological information of a driver. The external physical symptom detection system is configured to detect an external physical symptom of the driver. The processing device is coupled to the physiological information sensing system and the external physical symptom detection system. When the physiological information of the driver and the external physical symptom of the driver are abnormal, the processing device initiates an emergency procedure.

The invention comprises providing electric stimuli, which are generated by forming the following ringing circuit: active electrode—inductive storage unit—passive electrode—interelectrode tissues—active electrode, the electric stimuli creating oscillations which are used as a test signal. In one variant of the method, the electrodes are successively applied (in another variant—moved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The invention allows for both combined and disjointed (i.e. separated) electrode placement. An optimal zone for electropulse therapy is identified by a minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of small asymmetry. The invention further provides for an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.

A physiological signal monitoring system includes a single set of sensing electrodes to provide conditioned physiological signals to a primary monitoring device and a secondary monitoring device. The monitoring system includes pre-processing circuitry configured to receive a raw physiological signal. The pre-processing circuitry is configured to produce a primary physiological signal and a secondary physiological signal. Each of the primary and secondary physiological signals are conditioned. The primary conditioned physiological signal is directed to a primary monitoring device such as a hospital wearable defibrillator device. The secondary conditioned physiological signal is directed to telemetry modeling circuitry where it is further processed to output one or more telemetry signals. The one or more telemetry signals are output to a secondary monitoring device such as a three lead ECG monitoring device. Thus, a single set of sensing electrodes can provide physiological signals to multiple monitoring devices.
