    摘要: Paired bones are individually secured in an anatomically relevant manner onto independent, parallel positioned platforms, and configured into motorized models for the purpose of teaching and assessing clinicians' ability to identify and compare the relative positions of bony landmarks within the coronal and sagittal planes. One platform can be powered by two motors to generate precise landmark asymmetries, moving the platforms in the coronal plane and around a horizontal axis. As the platform shears upward or rotates forward, the landmarks on the bone attached to that platform can be moved superiorly compared to the other side. A central computer can instruct the motors of a plurality of models to move predetermined amounts via a two-way wireless communications link. The model can communicate back to the computer once the movement is completed, assuring a high level of precision in obtaining the intended positional asymmetry or informing the user that the move exceeds the limits of the model.

    摘要: A chemical sensor for detecting the presence of one or more analytes. The sensor comprises at least one electrode pair and a photopolymerized electrically conducting polymer composition disposed in contact between each of the electrode pairs. Each polymer composition may include an organic polymer capable of interacting with one or more analytes. The sensor also comprises a means for delivering an analyte to each polymer composition, and a means for processing the resultant electronic signal from each polymer composition and electrode pair. Preferably, the sensor comprises a plurality of different polymer compositions, each with a dedicated electrode pair, to generate a collection of signals that provide a fingerprint unique to a particular analyte.

    摘要: Hydrogen gas production includes supplying a hydrocarbon fluid to a gap between a pair of electrodes, applying a voltage across the electrodes to induce an electrical arc, wherein the electrical arc contacts the hydrocarbon to form a plasma and produces a gaseous product comprising hydrogen gas and a solid product comprising carbon, and dynamically adjusting the gap length to control at least one parameter of the plasma. Preferably, the gap length is decreased during plasma initiation or reformation and increased to increase the hydrogen gas production rate. The method preferably includes dynamically adjusting the spatial separation of the electrodes and rotating at least one electrode while generating hydrogen gas to reduce adherence of solids to the electrodes. Furthermore, the polarity of the electrodes may be periodically reversed, primarily to reduce adherence of solids. If the hydrocarbon fluid is a liquid, the method may include controlling the level of the hydrocarbon liquid relative to the pair of electrodes.
