The objective of this paper is to propose an energy-aware and gait corrected pedestrian dead reckoning (PDR) approach using foot-mounted magnetic, angular rate gravity (MARG) sensors. Compared with existing algorithms PDR, the proposed method aims solve three main problems for real applications. First, avoid limitations off-line calibration personal step length parameters, we utilize zero-veloc...

The objective of this study is to develop a post-impact vehicle stability control system that regulates both heading angle and lateral deviation from the original driving path, so that the severity of possible subsequent (secondary) crashes can be reduced. To characterize the vehicle motion after a crash event, an impact force estimation method and a vehicle motion prediction scheme are propose...

To meet the challenges of making low-cost MEMS yaw rate gyros for the precise self-localization of indoor mobile robots, this paper examines a practical and effective method of minimizing drift on the heading angle that relies solely on integration of rate signals from a gyro. The main idea of the proposed approach is consists of two parts; 1) self-identification of calibration coefficients tha...

Forest mapping, one of the main components of performing a forest inventory, is an important driving force in the development of laser scanning. Mobile laser scanning (MLS), in which laser scanners are installed on moving platforms, has been studied as a convenient measurement method for forest mapping in the past several years. Positioning and attitude accuracies are important for forest mappi...

Heading direction is determined from visual and vestibular cues. Both sensory modalities have been shown to have better direction discrimination for headings near straight ahead. Previous studies of visual heading estimation have not used the full range of stimuli, and vestibular heading estimation has not previously been reported. The current experiments measure human heading estimation in the...

Previously, we have looked at the stability augmentation system. This system can be seen as the inner loop of the aircraft control system. In this chapter, we focus on the outer loop: the control augmentation system. When we want to keep a certain pitch angle, velocity, roll angle, heading, or something similar, then we use the CAS. In this way, the pilot workload can be reduced significantly. ...
