Abstract: A preliminary guidance data is determined for the vehicle during an evaluation time window. A vision module collects vision data from a vision module during the evaluation time window. Vision guidance data is determined from the collected vision data. A vision quality estimator estimates vision quality data for at least one of the vision data and the vision guidance data during the evaluation time window. The vision quality data is based on a cross correlations and an r-squared value. An adjuster adjusts the preliminary guidance data to a revised guidance data based on the vision guidance data such that the revised guidance data is registered with or generally coextensive with the vision guidance data, if the vision quality data exceeds a minimum threshold.

Abstract: A system, program product and method for automatically adjusting the traffic light of a traffic light controlled intersection. Personal data relative to a pedestrian cross walking the intersection, including walking speed, and the current speed of a vehicle approaching the intersection are simultaneously acquired. Both the personal data and the vehicle current speed are processed to generate cross walk control signals, such as indicators of risk of collision between vehicle and pedestrian. Where the risk warrants action, the “stop” condition of the traffic light is enable to warn the vehicle to stop. Traffic control signals are also generated to control the duration of the “walk” condition for slow moving pedestrians.

Abstract: System and method alerting drivers approaching a pedestrian crossing and notifying them of the presence of a pedestrian on the pedestrian crossing or any other accidents-prone road sections. By this, an additional traffic safety measure is provided. The presence of the pedestrian crossing marking is not always sufficient. Thus, the proposed system and method are also directed at providing a forgiving infrastructure for both inattentive drivers and jaywalking pedestrians. The system and method utilize movement and weight sensors to detect a movement upon a pedestrian crossing and its vicinity. After negating a possibility that this movement is caused by a passing vehicle, the system invokes illuminating indicators directed at approaching drivers, alerting them to the presence of a pedestrian on the pedestrian crossing. The system may be calibrated to optimize the detection rate, minimizing false alarm and no detection.

Abstract: A gait waveform feature extracting method and an individual identification system extract features of the gait waveform. A one-step waveform corresponding to one step of a walking movement is specified using, as an index, a peak amplitude corresponding to a state where substantially a whole bottom surface of one foot is in contact with the ground and a toe of the other foot is just after leaving the ground among the electric field displacement formed on the human body in accordance with the human body's walking movements. Based on the specified one-step waveform, the features of the one-step waveform are extracted, so that the peak amplitude appears without influence from electric-charge interference between the right and left legs. Accordingly, the one-step waveform reflects the actual one step of the walking movement, and therefore, the features of the one-step waveform can be precisely extracted.
