  • Patent number: 6313374
    Abstract: A process for effectively remediating soils contaminated with individual or mixture of metal ions is described. The process involves utilizing plants of the genus Pelargonium, particularly Pelargonium sp., to hyperaccumulate metal ions in their roots and shoots. These plants when grown on soils, which contain one or more of the metal ions, individually or in a complex mixture, will uptake the metal ions through their roots and translocate them to the shoots. This process thereby removes the metal ions from the soil. The harvested shoot and root biomass can be used for extraction of essential aromatic oils, and the residual oil-extracted biomass will be available for extraction and recycling of the metals. The process also describes the use of the above said plant(s) for remediating land-farming sites of petroleum industries, which are generally contaminated with a mixture of metal ions and organic contaminants.

The component includes a heat source, a microstructural heat sink; and a thermoelectric device disposed between the heat source and the microstructural heat sink. During operation, heat flows from the heat source to the heat sink through the thermoelectric device such that the thermoelectric device can convert a portion of the heat flow into electric power. In some of the preferred aspects of the invention, the heat sink is an ultra thin film desorber combustor, and the heat source is a microchannel combustor. The microstructural architecture can provide high rates of thermal transfer through the thermoelectric device, allowing for surprisingly high thermoelectric power generation from a compact and light weight component.

  • Patent number: 6313401
    Abstract: A singly or doubly encapsulated actuator/sensor package in which a ceramic actuator/sensor (10) may be first encapsulated in a primary encapsulating material (12) and is encapsulated in a fiber-reinforced composite material (20, 22). A combination of the material and ply angles (&thgr;) of the fiber-reinforced composite material (20, 22) are used to control selection of a composite coefficient of thermal expansion (CTE) and the stiffness or compliance of the package with respect to a selected axis. By optimal selection of the material and the ply angle, based upon a suitable actuation strength figure of merit, a CTE of zero or a CTE matching that of an underlying structural member (24) is obtained, while simultaneously maximizing the actuation strength in a selected actuation direction.

  • Patent number: 6313402
    Abstract: A metallic or an electrical trace having a terminus and a stress relief bend formed in the trace adjacent the terminus. The electrical trace may have a portion carried by a flexible substrate to form a flexible circuit. The stress relief bend may be free floating and extend from the flexible substrate or may be encapsulated by the flexible substrate. The electrical circuit and the flexible circuit each have a generally planar portion extending in the X and Y axis, with the stress relief bend projecting into the Z axis. This allows electrical traces to be spaced with a very narrow pitch because the stress relief bend does not consume any valuable real estate on the flexible circuit or the substrate to which the electrical trace is applied.
