OBJECTIVE The aim of this study is to model occupant kinematics in an autonomous braking event by using a finite element (FE) human body model (HBM) with active muscles as a step toward HBMs that can be used for injury prediction in integrated precrash and crash simulations. METHODS Trunk and neck musculature was added to an existing FE HBM. Active muscle(More)
OBJECTIVE The aim of this study was to investigate the whole spine alignment in automotive seated postures for both genders and the effects of the spinal alignment patterns on cervical vertebral motion in rear impact using a human finite element (FE) model. METHODS Image data for 8 female and 7 male subjects in a seated posture acquired by an upright open(More)
Human body models (HBMs) for vehicle occupant simulations have recently been extended with active muscles and postural control strategies. Feedback control has been used to model occupant responses to autonomous braking interventions. However, driver postural responses during driver initiated braking differ greatly from autonomous braking. In the present(More)
We report new approach to stimulation of visual evoked potentials generating graphical shemes on display of personal computer. System is based on original research of authors. It permits a stimulation of individual types of retinal cells using either pattern reversal modus or movements, or their mutual combination. System is suitable for introduction into(More)
The study presents a methodical analysis and results of examinations of visual evoked potentials after stimulation by pattern reversion and motion in the visual field. The stimulus is generated on a PC monitor. In this manner selective stimulation of X and Y ganglionic cells is enabled by reversion, motion and their mutual combination. (Tab. 1, Fig. 2, Ref.(More)
