The design of a moderate gain embroidered antenna using the resonant cavity concept is presented. The patch as the main radiator and the partially reflective surface (PRS) structure as the superstrate are realized using an industrial embroidery machine. The PRS consists of periodic cross-slots (9 × 9 unit cells) in order to have a durable embroidered structure. The groundplane is made of a conductive woven fabric. The fabricated antenna has a relatively broad 1 dB-gain-bandwidth (10%) and a directive pattern (3 dB beam-width of 40° at the center frequency). Despite the higher losses in the conductive thread due to the resonant cavity effect, this antenna has a maximum realized gain of 6.8 dBi, which is typically 3 to 6 dB more than other embroidered single patch antennas.
 
Sewing Machines are arranged dependent on their usefulness, and they have likewise been ordered relying upon their highlights like sewing, knitting and weaving.

Based on stitch filling of patterns of embroidery machines, we divide images into blocks according to colours, i.e. quantify the three components of H, S and I under the HIS coloured model. There are two sorts of quantification methods at present: uniformly-spaced quantification and non-uniformly-spaced quantification. Uniformly-spaced quantification makes uniformly- spaced partition of each component in its own domain. For example, tone H (0-360) can be divided equally into 6 portions and every 60 consist of one portion which can be divided into 6 categories, i.e. six-dimensional characteristic quantity. Because people have uneven perception of tone when seeing them, capturing characteristic quantity by non-uniformly-spaced quantification is a common method.
 
The spark and crackle typically associated with new consumer electronics were subdued during 1975. Though the spotlight played briefly on video disks, little hardware is yet available — excitement dissipated quickly, awaiting the “big push” still scheduled for late this year when MCA/Philips and RCA start marketing players in the United States. Calculators were personal, portabl, and plentiful this past year, with new entries by Hewlett-Packard and Texas Instruments leading the pack. And jewelers, accustomed to the familiar tick of mechanical timepieces, had to adjust to the silence of the digital watch-which, as prices tumble, is showing up in chain store windows as well as posh display cases. Here, the technology tug-of-war revolves around readouts: light-emitting diodes (LEDs) vs. liquid crystal displays (LCDs).
