Subject: Re: FCC ID: A3LAT67L6D Attachments: DMD04.pdf; DMD03.pdf; DMD05.pdf Dear Gregory, Regarding to your requests, I send you technical description of subject equipment as attached. But, I couldn't see the ferrite core even though you have seen 2 ferrite cores on the D-sub cable in test set-up photos. Could you let me know which page's photos of test report include 2 ferrite core. As I confirmation with engineers in korea today, this equipment did not used any ferrite core. Please verifiy it, then reply me.

Mankind’s early fascination with the viewing of life- like moving images led to the development of a vari- ety of optical gadgets in the 19 th century. One of the earliest was the phenakistoscope, a set of phased drawings mounted on a twirling disk (circa 1832). With the invention of the positive photographic process in 1839 by Daguerre, the drawings were replaced with a succession of phased photographs. These optical toys were based on the understand- ing that a closely spaced series of images could be used to portray a sense of time and motion. This entertainment curiosity was intriguing enough to become a popular and rather sizeable niche business, although the subject or content of the flipping images was of little creative value. Revenues were limited by the fact that only one person could view the images at a time by peering into an eyehole. It was not until the invention of the motion-picture camera, or “Kinetograph,” in 1887 by Thomas Alva Edison, (or his assistant Dickson, as some would argue) that a continuous set of photographic images could be generated. An adjunct to the Kinetograph was a single-viewer apparatus called the “Kinetoscope.” During an exhibition in Paris, a Kinetoscope demonstration inspired the Lumiere brothers, Auguste and Louis, to invent the first com- mercially viable film projector, the “cinematographe.” The first public screening using this new technology was in Paris on December 28, 1895. This event is gen- erally regarded as the birth of the “cinema.” Film projection technology enabled a new business model based on a large (paying) audience who could simultaneously view the same content, thereby allowing higher revenue potential than the early sin- gle-viewer novelties. This fueled the creative passions of the early movie moguls, who founded the movie entertainment business, using photographic film as their capture and display medium. Beyond the increased profit potential, projection technology enabled a large audience to view a motion picture together as a “shared experience,” enhancing the enjoyment in much the same way as when people experience a symphony, play, sports or other group entertainment. JULY–SEPTEMBER19987 DIGITAL LIGHT PROCESSING—INTRODUCTION From cathode rays to digital micromirrors: A history of electronic projection display technology Abstract:In the late 1800s it was called “distant electric vision” or the “electric telescope,” words to describe mankind’s dream to see instantaneously beyond the hori- zon with electric technology. Today we use the word televi- sion. The early window for seeing beyond the horizon was the cathode ray tube or CRT, first demonstrated in crude form in 1897 and developed as a “practical” window in 1929. In the late 1940s following World War II, motion picture studios in concert with the fledgling television industry sought to bring live programming to the movie theater audience. This was the birth of “big-screen” elec- tronic projection display technology. Projection CRTs led the way, but soon, the forerunner of the modern laser dis- play as well as the first spatial light modulator or “light valve” made their commercial debuts. Over the following 50 years, the display industry has searched for the ultimate big-screen technology, not only for the theater, but also for the trade show, classroom, boardroom and living room. An ingenious and sometimes bewildering array of projection technologies has been developed, with the goal of producing brighter, higher fidelity images with displays having lower weight and cost. This article describes those technologies as they evolved, beginning with the early ones based on the CRT and e-beam addressed oil films and continuing to the pre- sent day technologies of improved CRTs, scanned laser beams, the liquid crystal display (LCD), and culminating with the all-digital technology Digital Light Processing™ (DLP™) based on the Digital Micromirror Device™ (DMD™). Larry J. Hornbeck Film-based projection technology has its limita- tions, however, including its inability to provide live content to the audience, the expense of the film prints (including transportation costs) and their inexorable deterioration with repeated screenings. Electronic projection display technology provides an answer to these shortcomings, but the stimulus for its develop- ment had to await the age of commercial television. The grandfather of electronic displays, the CRT or cathode-ray tube, was invented more than 100 years ago. In spite of its age, the CRT is still the dominant display technology today. In the 1940s motion picture studios and the youthful television industry sought to bring live television programming to the theater by using electronic projection technology, but the CRT lacked the necessary brightness. The so-called “light-valve” technologies were developed primarily for sports-driven display venues. In other, less demanding applications, the CRT remained domi- nant because light-valve technologies were too expensive, bulky and heavy. But recently, new light-valve technologies are replacing both the CRT and the older first- and second-generation light valves in high-brightness dis- play venues. And because these new light-valve tech- nologies can be designed into more compact prod- ucts, their availability has opened up new market opportunities where low weight and portability are required. Perhaps soon, the CRT will be replaced in high-end consumer projection display products for the home as well. The projection CRT’s longevity can be attributed to several factors. First, although the projection CRT is considered a “mature” technology, it has been steadily improved over a long period and incremen- tal improvements are even being made today. And second, until recently light-valve technologies were unable to take full advantage of the economies and stability offered by the digital electronics revolution. This digital age has brought us such advanced ser- vices and products as the Intern…
