The present invention relates to multifilament crimped yarn comprising an aliphatic polyester and methods for producing thereof, and to carpets that are manufactured by using the crimped yarn. Various implementations are discussed, including raster scan, line scan, and compressive sampling version. The method includes registering a bit plane containing a plurality of bits in a register module, wherein each bit represents whether a corresponding element of the data matrix equals zero. , J-rods on a fixed pedestal support or a marching drum carrier, and another part of the hinge connectable to the shell of a drum or to the tension rods on a drum or to other supporting hardware installed on the drum. The polyarylene polymers are suitable for use as engineering polymers.
