    摘要: A system and method for a pulsed light source used in detecting fluorescence from a plurality of samples of biological material discretely, continuously or intermittently during thermal cycling of DNA to accomplish a polymerase chain reaction (PCR). An apparatus for sampling at least one sample of a biological material comprises a light source that emits a pulsed excitation light that interacts with the sample and a detector sensitive to fluorescence emitted from the sample. A method of sampling at least one sample to detect fluorescence comprises generating a pulsed excitation light with a pulsed light source; directing the pulsed excitation light into the sample; illuminating a sample with the pulsed excitation light to generate an emission light; and detecting the optical characteristics of the emission light.

    摘要: The invention relates to an apparatus and methods for preventing condensation on the interior surfaces of sample tubes which are being exposed to temperature cycles, such as during a PCR amplification reaction. In particular, the invention relates to apparatus comprising a sample block comprising a plurality of sample wells for receiving sample tubes and heating elements disposed in the sample wells for heating at least a portion of the sides of sample tubes (e.g., at least the portion which forms the head space after a tube is filled with a PCR reaction mixture). In a preferred aspect, the sample block is part of a thermocycling device for performing PCR and the side-wall heater is used to enhance uniformity and speed of amplification reactions. For example, by decreasing or eliminating condensation, signal strength jumps in a real-time PCR assay can be minimized as can reaction non-homogeneity.

    摘要: A baseball batting practice device is disclosed as a bat having a recess formed at the large end to nestingly receive a spinning reel. The reel is oriented to pay-out a fishing line at a right angle to the bat axis, the fishing line is secured to a baseball and serves as a tether to retrieve the ball using the reel. With the tether payed out at a right angle to the bat axis, minimum resistance to the flight of the ball is observed and the distance traveled by the ball replicates that of an untethered ball.

    摘要: A variable-incline ramp system guides a vehicle through the incline between a first site and a second site while at all times maintaining the vehicle in its natural horizontal orientation. The ramp system includes a separate set of rails for guiding the front and the rear wheels of the vehicle. In profile, the two sets of rails form a parallelogram having one pair of sides of a length equal to the wheelbase of the vehicle. So long as these parallelogram sides are horizontally oriented, the vehicle traveling along the rails will maintain its normal orientation because its wheelbase axis will be parallel to the horizontal sides of the parallelogram. In one embodiment suited for use in marine settings, the rails are movably connected to the first and second sites such that as the site elevations change, the parallelogram is free to skew while still remaining a parallelogram with the same length sides.
