The manipulator device includes a pedestal and a carrying mechanism which carries a platform and which forms an articulated triangle comprising: a first arm borne by a first carriage with a first pivot link whose axis forms a first vertex of the triangle, a second arm borne by a second carriage with a second pivot link whose axis forms a second vertex of the triangle, a seat situated at the intersection of the first arm and of the second arm, which forms a third pivot link whose axis is parallel to the first pivot axis and the second pivot axis and forms a third vertex of the triangle. A module is provided for servocontrolling the translational movements of the first carriage and the second carriage with respect to the pedestal. A yaw orientation interface comprises a fourth pivot link, by which the platform is articulated on the seat, both relative to the first arm and relative to the second arm, about a fourth pivot axis which is coaxial to the third pivot axis.

A reveal edge tile cutting apparatus is provided for. The reveal edge tile cutting apparatus has a tray with a top surface and a bottom surface, as well as a first set of tracks and a second set of tracks. Attached to these tracks is a vertical cutter featuring two cutting wheels, a horizontal cutter featuring a separate cutting wheel. A measuring device may be located on the top surface of the tray.

The cutting system is configured to cut a continuous strip which extends lengthwise in a longitudinal direction and widthwise between a first edge and a second edge into strips. The cutting system includes a drive device which imparts to the continuous strip a feed speed, a first cutting roller and a contrarotating second cutting roller that cooperate to cut the continuous strip across its full width. The first cutting roller is provided with a first helical blade and is driven in rotation A variable synchronizer makes it possible to select and to modify the synchronization ratio between the rotational speed of the first cutting roller and the non-zero forward speed of the continuous strip in such a way as to be able to adjust the cutting angle according to which the cross-section of the continuous strip is oriented with respect to the longitudinal direction of the continuous strip.

This application relates to an amplifier selectively operable in first or second modes. The first mode is a BTL mode with first and second output drivers (103p, 103n) both active to generate respective driving signals that vary with an input signal. The second mode is an SE mode, where the first output driver (103p) is active to generate a driving signal at and the output of the second driver (103n) is held constant. A controller (201) selectively controls the mode based on an indication of output signal amplitude. In the first mode, a ratio of magnitude of the two driving signals varies with the indication of output signal amplitude, i.e. the magnitudes of the two driving signals may vary so as to be not equal.
