Abstract: Quiet, lightweight, well-balanced, forgiving, and accurate compound archery bows which have significantly reduced vibration and bow jump. The limbs and cams of these bows can be removed and replaced without a bow press, and the limbs of the bows are functional (active) over essentially their entire length and allow one to obtain equivalent performance from a more compact and lighter bow. The bow limbs may be leverage locked in articulated limb pockets. The limb butts extend forward well beyond the front of the riser. This eliminates limb length and limb angle as major factors in determining brace height, allowing one to choose a riser style and limb length which optimize arrow speed and bow stabilization. Novel adjustment mechanisms allow one to easily adjust the poundage or poundage and brace height of the bow. Vibration isolation systems may be employed to isolate the bow riser from the limb pockets.

Abstract: A device and method for sampling a fluid, especially a fluid of varying densities, are provided. The device includes a retention tube configured to receive a sample of the fluid, and can include a support jacket to support the retention tube. A control member is positioned within the retention tube with a plug attached to the distal end. The plug is movable away from the opening to facilitate laminar flow of the fluid into the retention tube. The plug can sealably engage the retention tube by affixing a portion of the control member. The device can be jolted to cause the control member to stretch, which disengages the plug temporarily, thereby releasing a lab sample portion from the retention tube. The rest of the sample of fluid can be released by completely releasing the plug from sealing contact.

Abstract: A riser formed from a plurality of curved cylindrical segments with vertical side edges having mating vertically tapered projections and slots brought into interlocking engagement to pull confronting surfaces together as the tapered elements become increasingly mechanically engaged. The segments are assembled by a sliding engagement of the protruding mating element of one segment into the vertically tapered slot of an adjacent segment. When sufficient segments are joined together horizontally to complete a ring except for a last adjacent pair of vertical side edges, the ring is warped to align the protruding mating element of the last adjacent pair of vertical side edges with an opposite end of the adjacent tapered slot. Thus aligned, the final protruding mating element and tapered slot are then slipped together while un-warping the joined segments forming the remainder of the ring until the top and bottom ends of all the segments are aligned.

Abstract: The invention relates to a method and/or apparatus to improve the visual perception of an image displayed on a liquid crystal (LCD) panel, said method comprising steps for generating an adjusting signal (PE,i+1) of a rear-lighting lamp of said panel depending on an target power value (PT) and for generating a control signal (CE,i+1) of the image contrast depending on said adjusting signal (PE,i+1) of the rear-lighting lamp so as to increase/decrease the contrast of the displayed image when said adjusting signal (PE,i+1) of the rear-lighting lamp decreases/increases.

Abstract: Ball bats comprising a stem and a handle surrounding the stem. An elastomeric decoupler system installed in the handle sharply reduces the transmission of shocks and vibrations from the stem to the handle, mitigating stinging and other unpleasant sensations experienced by the batter when a ball is struck. Unpleasant sensations can be further reduced by installing a DTMS damping device in the knob of the bat and by installing an elastomeric grip on the handle of the bat; and the unpleasant sound made when a bat strikes the ground or the like can be materially reduced by a device attached to the stem of the bat intermediate the ends of the handle. The present inventions are particularly adaptable to hollow, metal bats; and provision is made for venting the knob of the bat when it is welded in place so hot gases will not be forced into, and reduce the integrity of, the weld. Appropriate ones of the devices described above may also advantageously be employed in wood, composite, and other bats.
