Abstract: Provided is a cable connector, a cable assembly, and a method of manufacturing the cable assembly, in which electric characteristics are stabilized by suppressing elastic deformation of a cable for differential signal transmission, and besides, which is easily connectable by reducing the number of parts. In a ground contact, an outer-conductor adhering portion which is protruded from a side wall portion of a connector main body and which is adhered with an outer conductor by a conductive adhesive is provided. In this manner, elastic deformation of a cable for differential signal transmission is suppressed, so that electric characteristics can be stabilized. Also, connecting work between the outer conductor and the ground contact can be simplified as reducing the number of parts. Further, the cable for differential signal transmission is not exposed to a high temperature of soldering or others, and therefore, thermal deformation thereof does not occur, either.

Abstract: An electromechanical device for simulation of physical exercises with legs and arms includes two pedals assembled in two contiguous pantographs, each with a parallel suspension arm predominantly vertical, one junction orthogonal and parallel arms predominantly horizontally articulated in the frame of the device. The pantographs act always in opposition to the movement of the left and right throw traverses articulated in axis respectively vertical and horizontal, connected to vertical and horizontal parallel bars by holders, and the movements are angular of the traverses transmitted to electromagnetic breaks with a belt system. Pulleys and ratchets transform the angular alternative movement into a one way circular movement in the flywheels that have electromagnetic breaks. A control panel of braking and interpretation of sensors of angular movement of the traverses provides information to the user and feed of a display with recent stride of the pedal.
