Abstract:
A force reflection system comprising:a building structure; an electric power cable mounted to the building structure and carrying a voltage having a maximum supply voltage level; a power outlet mounted to the building structure and connected to the electric power cable so that the power outlet is substantially at the voltage level of the power cable; a support frame located in a stationary relationship relative to the building structure; a linkage mechanism having a first portion and a second portion being movable relative to the first portion, the first portion being mounted to the frame; a user interface device having a component secured to the second portion of the linkage mechanism, and having a surface shaped for contact by a body part of a person, movement of the second portion of the linkage mechanism relative to the first portion thereof causing movement of the user interface device relative to the frame; an electric motor having a motor body, an actuating component, an electric voltage supply terminal, wherein, when a current is applied to the supply terminal, the actuating component is caused to move relative to the motor body, the motor being connected between two components of the frame and the linkage mechanism such that movement of the actuating component causes movement of the second portion of the linkage mechanism relative to the first portion thereof with a corresponding movement of the user interface device relative to the frame and the holding structure; a connector connected to the power outlet; and an electric power supply link connecting the connector to the supply terminal so that the supply terminal is a at voltage level which is at least 70% of the maximum supply voltage level.
