This paper discuses sensor steering mechanism (SSM) for a laterally guided vehicle with a rear wheel steering mechanism. The authors have demonstrated the geometry of SSMs for front wheel steering type and reverse phase four-wheel steering type vehicles. SSMs allow stable lateral guiding performance for automated vehicles following a path with straight and curved portions created by a guideway....

Dynamic behaviour of motorcycles front wheel are not different to similar wheel suspensionmotion of airplanes and road vehicles. In every case self excited oscillations caused bythe tire occur. Only the different design of wheel suspension produces some differentcoupling. The deviation of a moving wheel on a horizontal plane from straight rolling iscaused by unstable lateral con...

An articulated lorry was instrumented in order to measure its performance in straight-line braking. The trailer was fitted with two interchangeable tandem axle sub–chassis, one with an air suspension and the other with a steel monoleaf 4–spring suspension. The brakes were only applied to the trailer axles, which were fitted with anti–lock braking systems (ABS), with the brake torque controlled ...

This paper discusses the mechanics of a rigid rimless spoked wheel, or regular polygon, ‘rolling’ downhill. By rolling, we mean motions in which the wheel pivots on one ‘support’ spoke until another spoke collides with the ground, followed by transfer of support to that spoke, and so on. We carry out three-dimensional numerical and analytical stability studies of steady motions of this system. ...

Objectives: Different chelators may be used during root canal treatment, offering various advantages including lubricant effect inside the canal and smear layer removal. However, chelator residues in narrow root canals can lead to apical microleakage. The aim of this in-vitro study was to compare apical microleakage following the use of three root canal chelators via fluid filtration method in ...

This paper presents the architecture of a software system able to assess the cognitive effort of a driver by monitoring the interaction between the driver and the steering wheel; this system is called WL Manager (WLM). The advantage of a Workload Manager System based on the steering dynamic is that of being not invasive in comparison to other workload measures, in particular physiological (hear...

A new hybrid wheelchair/bed system for assisting the bedridden has been developed and tested. The powered wheelchair docks with a stationary bed and reconfigures to a chair to provide full mobility assistance by eliminating the need to transfer the bedridden person from bed to chair. Furthermore, the chair can dock directly and automatically with a toilet to eliminate the need to change seating...
