A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...

A shared lane keeping assistance system supports the driver in the steering task. In contrast to an autonomous system, the shared system works in parallel with the driver by applying an additional torque on the steering wheel. This means the system and the driver perform the steering task in cooperation. As the driver is still part of the control loop a driver model is required to predict the s...

This paper presents a new approach to closed-loop control of optical jitter with a new liquid crystal beam steering device. In contrast to conventional fast steering mirrors, where the laser beam is reflected of the controlled mirror surface, the transmissive liquid crystal beam steering device optically redirects the laser beam. The new device has no moving parts and requires low operating pow...

In spite of the presence of powered wheelchairs, some of the users still experience steering challenges and manoeuvring difficulties that limit their capacity of navigating effectively. For such users, steering support and assistive systems may be very necessary. To appreciate the assistance, there is need that the assistive control is adaptable to the user's steering behaviour. This paper cont...

Optical phased arrays are versatile components enabling rapid and precise beam steering. An integrated approach is followed in which a 1D optical phased array is fabricated on silicon-on-insulator. The optical phased array consists of 16 parallel grating couplers spaced 2 mum apart. Steering in one direction is done thermo-optically by means of a titanium electrode on top of the structure using...

This paper describes a conceptual model for computational program steering. By exploiting previous results attained in program monitoring, debugging, and connguration, the abstractions and mechanisms derived from this model are shown suitable for both algorithmic and human interactive steering. A characterization of existing systems for computational steering using the model's abstractions demo...

In this paper, we extend our previous model circuit for steering in C. elegans to control a more realistic biomechanical model of forward locomotion. We show that the identified steering circuit is sufficient to steer the full body during forward locomotion while only innervating a few of the anterior most neck muscles. Analysis of the sensorimotor transformation and phasic stimulation experime...

Steering behaviors are a set of motion based reactive procedures used for navigating autonomous agents in their environment. Combinations of steering behaviors can be used to create complex behaviors. One problem inherent to existing approaches to arbitrating between single behaviors is that their combination may lead to suboptimal, undesired, or even catastrophic results in certain situations....

Steer-by-wire (SBW) systems, which have no mechanical linkage between the steering wheel and front wheels, are expected to improve vehicle safety through better steering capability. SBW system failures, however, can cause hazardous driving situations. This paper introduces fault-tolerant architecture based on diversified steering mechanisms consisting of SBW backed up with steering by braking a...

This paper deals with the optimization analysis of Steering Rack. Steering Rack Bending CAE analysis technology is indispensable for developing and mass-producing the Steering Gear assembly. By using Finite Element method, a stress analysis has been carried out. Steering Rack Deflection and Bending stresses are found. Various CAE iterations shows rack weight reduction by keeping Stress constant...
