Abstract: A chromatograph is provided for identifying components of a mixture. Components are identified by different rates of adsorption and/or desorption with a material phase. In one embodiment, an electrical lead is connected to the material phase for supplying an electrical charge to the material phase. The electrical charge alters the rate of adsorption/desorption of the components with the material phase. In another embodiment, the material phase is disposed between two conductors with electrical leads connected to each of the conductors. A charge differential between the two conductors alters the rate of adsorption and/or desorption of components with the material phase.

Abstract: A system includes a gearbox having an external surface; a fan or impeller constructed to generate a first cooling airflow when rotated; a shroud operative to guide and discharge the first cooling airflow over the external surface and cool the gearbox, wherein at least a portion of the shroud is spaced apart from the gearbox and disposed radially outward of the external surface; and a flow entrainment structure coupled to the gearbox and/or the shroud, wherein the flow entrainment structure is constructed to entrain a second cooling airflow and combine the second cooling airflow with the first cooling airflow to form a combined cooling airflow directed across the external surface to cool the gearbox.

Abstract: A light emitting diode (LED) sensor including a first LED device disposed on a support and configured to emit a radiation, and a second LED device disposed on the support and configured to receive the emitted radiation. A structure is formed on the support, the first LED device, and the second LED device. The structure defines a contoured surface. A material is located adjacently to the contoured surface, wherein the material includes a property adapted to reflect the emitted radiation from the first LED to the second LED. The structure includes an ellipsoid and the contoured surface defines an ellipsoidal surface. First and second foci are defined by the ellipsoid, wherein emitted radiation from the first LED device converges at the first foci and the second foci and is reflected to the second LED device. The device is configured to determine a temperature or a chemical property of an analyte.
