A new overground body-weight support system called ZeroG has been developed that allows patients with severe gait impairments to practice gait and balance activities in a safe, controlled manner. The unloading system is capable of providing up to 300 lb of static support and 150 lb of dynamic (or constant force) support using a custom-series elastic actuator. The unloading system is mounted to ...

One might despair of ever arriving at a principle adequate to capturing and accommodating our intuitions about the full range of cases that have come to be known as “trolley problems” (roughly speaking, cases where one must choose whether to kill some to save others). But suppose there were such a principle, as indeed I imagine there probably is. For the moment, just call it Q. Is there such a ...

This paper discusses automation of maintenance of belt conveyor systems, in particular of idler rolls. Automation of maintenance is a promising alternative for outsourcing maintenance, in particular when looking at the efficiency, accuracy, and costs. In order to optimise maintenance efforts, the concept of intelligent maintenance is introduced. The powered maintenance trolley that can travel a...

Pada penelitian ini dilakukan analisa daya Motor Hoist dan Trolley pada Container Crane (CC) dengan menggunakan beban peti kemas yang fluktuaktif. Analisa dibagi menjadi dua yaitu motor saat proses hoist-up trolley trolley-reverse. Penelitian mengacu pengukuran berdasarkan parameter sudah ada sistem di PELINDO. digunakan untuk mengetahui rata-rata sehingga dasar melakukan pengembangan lebih lan...

A process employing a computer controlled crane system for controlling the motion of a movable trolley from which a load is suspended at a variable hoist length therefrom to meet a selected arbitrary horizontal velocity reference while preventing sway of the load involves the steps of first, determining a lateral acceleration to reduce by a factor of one-half the sway energy contributed by (1) ...
