TMLE-D5 series embroidery machines, with a pair arrangement of lock-stitch-handle embroidery heads, which were capable of sewing multiple threads. Brother Industries entered the embroidery industry after several computerized embroidery companies contracted it to provide sewing heads. Pulse Microsystems developed software for them called PG1. PG1 had tight integration with the embroidery machine using high-level protocol, enabling the machine to pull designs from software, rather than having the software push designs to the machine. This approach is still used today. Melco was acquired by Saurer in 1989. The early 1990s were quiet for machine embroidery, but Tajima introduced a 12 needle machine into their series along with a noise reduction mechanism. In 1995, Tajima added a multi-color (6-color) type to chenille embroidery machines and announced the ability to mix embroidery machines with plain chenille embroidery. They also began sales of the TLFD Series Laser-cut Embroidery Machines. In 1996, Pulse Microsystems introduced the computational geometry-based simulation of hand-created chenille using a spiral effect. Following this in 1997, Tajima introduced 15-needle machines, in response to the "multi-color-age". In the late 1990s, Pulse Microsystems introduced networking to embroidery machines. It added a box, which allowed them to network and then pulls designs from a central server. It also provided machine feedback and allowed machines to be optically isolated to protect machines in an industrial environment. Since then, computerized machine embroidery has grown in popularity as costs have fallen for computers, software, and embroidery machines. In the year 2000, Pulse Microsystems introduced Stitchport, which is a server-based embroidery engine for embroidery in a browser. This allowed for the factory automation of letter creation. Although they were not yet ready for it, this transformed the apparel industry by allowing manufacturers, stores, and end-users access to customized versions of the mass-produced garments and goods they had been buying throughout their lives, with no margin of error. In 2001, Tajima created heater-wire sewing machines, which were innovative, combination machines. In an environment that was finally ready for the individuality that mass customization allowed, the principles developed for Stitchport were adapted in 2008 for the creation of PulseID. PulseID allows for the automation of personalization, even on the largest industrial scale. In 2013, Tajima released the TMAR-KC Series Multi-Head Embroidery Machine, equipped with a digitally controlled presser foot. The major embroidery machine companies and software developers are continuing to adapt their commercial systems to market them for home use,
