摘要： An antenna structure, used for being fed with a signal, includes a grounding portion, a radiation portion, and a frequency adjusting portion. The radiation portion has a loop segment, a high frequency segment, and a low frequency segment. The loop segment has a feeding sub-segment adjacent to the grounding portion and used for being fed with the signal. The high and low frequency segments are extended from opposite ends of the loop segment away from each other. The frequency adjusting portion is connected to the loop segment and the grounding portion. A high frequency dual-path is formed from a feeding point of the feeding sub-segment and extends along the loop segment in two different directions to the high frequency segment. A low frequency dual-path is formed from the feeding point and extends along the loop segment in two different directions to the low frequency segment.

摘要： A method for minimizing color-image halftone dot-gain in the output of a multi-level halftone color-imaging output device. The method includes characterizing that device's halftone output, on a per-color basis, regarding pixel-pattern-specific dot gain which can be related to device pixel-infeed intensity levels, and from that characterizing, creating, and then applying to throughput color-image files, on a pixel-by-pixel basis, and for each output color producible by the device, a pixel-to-device infeed intensity correction value, thus to minimize device-output dot gain.

摘要： A method for controlling color bleed in relation to a system-invoked halftone color-image process which involves and includes the practice of error diffusion. The proposed method involves (a) selecting a location in the system which is downstream therein relative to where error diffusion takes place, (b) at that location, performing diffusion-accumulated error calculation, (c) at another location in the system which is downstream from where error calculation takes place, applying error filtering to define a numerically weighted pixel-neighbor distribution pattern for such calculated accumulated error, where the numbers associated with that pattern add to a defined distribution-weight totality number, and (d) then preparing, for use in a next-pixel error-diffusion event, a chosen distribution-weight totality number which is less than the defined distribution-weight totality number.

摘要： An improved vector error diffusion (VED) method employable in cycles with respect to a bi-tonal color printing engine which prints bi-tonal color images in a device output color space. The method includes (a) acquiring input color-image data which is characterized with an input color space, (b) processing, with available pre-established VED accumulated error data, such input data to produce a VED-processed input color-image data stream, (c) from such VED-processed input color-image data stream, creating, without employing interpolation, a VED-processed output color-image data stream which is characterized by the mentioned device output color space, and which is suitable for delivery to and use by the mentioned printing engine, and (d) changing, as appropriate for the next cycle, the VED accumulated error data which will be employed in that next cycle as pre-established VED accumulated error data. The step of creating includes employing, in addition to luminance-value thresholding to declare certain colors to be white, a color data palette which contains solely (1) a set of device output-color-space pixel values based upon spectrophotometric evaluated actual output print engine performance, and (2) three fictional device output-color-space values which lie intermediate the primary output-color-space values and white.

摘要： A radio frequency identification (RFID) device includes a metallic antenna plate, a first metallic tube, and a second metallic tube. The metallic antenna plate has a positioning portion and defines a central axis, a first hole, and a second hole. The positioning portion is formed in the path of the central axis and surrounds the second hole. The first and second metallic tubes are disposed on the metallic antenna plate. The first and second metallic tubes each has one end disposed on the positioning portion. The first and second metallic tubes extend across the first and second holes, respectively and are welded to the metallic antenna plate. The portion of the second metallic tube that extends across the second hole is approximately perpendicular to the portion of the first metallic tube that extends across the first hole.
