Abstract: The invention refers to a “fishing lure and bait structure” that comprises a fishing lure and bait body of an arc-shaped bar, which is cracks easily and produces the vibrations at the area near its arc center when it is bitten by the fish; this produces biomimetic movements such as wiggling irregularly along the waves while floating on the water surface and sinking underwater by non-linearity; its core and periphery are made of materials of different densities and water absorbencies to achieve self-movements while being thrown out into the water or bitten by the fish; this can further resemble the characteristics of insect shells or fish bones to produce the vibration waves of shells crashing or bones cracking so as to attract the fish to pursue the bait.

Abstract: An ultraviolet detector/indicator comprises of a column, hemisphere, cake, or wire where a light receiving front and a light emitting front are respectively installed on the two ends with connections, and a light guide unit, which contains the material that strengthens the ultraviolet or adjusts the spectrum is installed between the two fronts. According to the foregoing structure, the ultraviolet detector/indicator installed in the enclosure of an ultraviolet sterilization apparatus is exempted from the external power source for transferring invisible ultraviolet into visible light. In addition, a calorimetric scale printed with various color shades is installed to assist the user in verifying the ultraviolet strengths should aging or damage of the ultraviolet lamp fail functions of the apparatus. Furthermore, an interface connecting to the enclosure is installed to facilitate the replacement of ultraviolet detector/indicator.

Abstract: A displayable lighter package includes a display stand including a circular upper deck having an upper receiving cavity, a circular lower deck having a lower receiving cavity, and a central supporting shaft detachably supported between the upper deck and the lower deck in a rotatably movable manner. A lighter holder arrangement for securely holding at least a lighter on the display stand includes an upper holder and a lower holder fittedly disposed in the upper and lower receiving cavities respectively, wherein a plurality of upper holding slots are radially formed on the upper and lower holders respectively and adapted for securely supporting bottom portions of lighters on the upper and lower holders respectively. A stand base is detachably mounted underneath said lower deck for enabling said display stand in a rotatably movable manner. A cover is detachably sheltered the display stand for protecting the lighters mounted thereon.

Abstract: A Doppler ultrasound clutter suppression system and method in which the clutter is first low-pass filtered (716) to suppress the flow component (4024) just before mean frequency estimation (718). The mean frequency is then estimated and mixed with the original clutter data which is positioned at DC. The low-pass filter bandwidth is predetermined based on the particular application and imaging parameters. The signal is then high-pass filtered (726) to remove the clutter component (4022).
