In Cross Stitch it is important that the top leg of the stitch always runs in the same direction. This gives an attractive surface to reflect the light. If you stitch a row of the bottom legs, completing the crosses with the top legs on the return it is called 'Danish' Cross Stitch. Partial stitches come in three kinds half-stitch, quarter-stitch, and three-quarter-stitch. They're very handy for detail work, shading, and rounding shapes to avoid the stair-step look.
Brake Assist System. Brake Assist measures the speed and force of brake application to determine whether the driver is attempting an emergency stop. If such an emergency is determined, the system applies additional brake pressure to allow the driver to take full advantage of the Antilock Braking System (ABS) which prevents wheel lock up.
Driver-assist systems provide audible or visual (and sometimes physical) alerts if they sense a potentially dangerous situation, and some can even take action such as applying the brakes to avoid a collision or steering a car back into its lane.
