Abstract:
A device for measuring the relative placement of two terminal animate links separated by at least two animate joints of at least one animate kinematic chain using a device kinematic chain extending over said animate kinematic chain, said device comprising:individual attachments for attaching to each of said two terminal animate links;at least four sensing device joints in said device chain displaced from said animate joints, wherein two sensing device joints are situated on opposite ends of the same device link in said device kinematic chain, the number of said sensing device joints being at least sufficient to determine the relative placement of said two terminal animate links;each said sensing device joint comprising means for producing electrical signals related to the angle of said sensing device joint;five device links in series joined by said four sensing device joints as members of said device kinematic chain, with individual device links connected to each of said attachments and displaced from said animate links; andsignal transmission means for transmitting said electrical signals to a signal processing means to determine the relative placement of said two terminal animate links.
