Abstract: An integrated thermal apparatus for improved electronic device performance has an energy storage device coupled with a thermoelectric management device for managing thermal energy generated by the electronic device. The thermoelectric management device can include a semiconductor thermoelectric device and phase change material, which can be integrated into a foam aluminum structure. The energy storage device can be a nanometallic device. The electrical load electrical efficiency is improved by co-locating it with thermoelectric management device directly on a composite substrate foundation to provide enhanced waste heat conversion to electrical energy. The apparatus manages the thermal and power issues at the substrate level in close proximity to the electrical load and incorporates the needed thermal mass into the support structure by way of a phase change material.

Abstract: A capacitive electrical energy storage structure is fabricated as a thin-film device comprising electrodes on opposite sides of a dielectric layer. In one approach, a high surface area metallic sponge can be incorporated into the structure. The energy storage structure can comprise either single or multiple layers of capacitors connected in series, parallel, or a combination of such arrangements. The multi-layer capacitor structure can be either applied directly to supporting structures of portable or transportable devices or can be fabricated as a film which is applied as a laminate to such structures. Further, a conformal energy storage structure can be produced which is shaped to fit in voids within devices, which voids would otherwise be little used or unused.

Abstract: A gas turbine engine of a ducted-fan bypass type includes a fan with a plurality of circumferentially spaced airfoils thereon each including first and second portions thereof defining a forward thrust airfoil having a chord to blade spacing ratio greater than one. Each of the first and second portions are rotatably supported on the fan hub and are movable from a forward thrust position when the trailing edge of the first portion is juxtaposed against the leading edge of the second portion to a reverse thrust position wherein the first and second portions are corotated so as to locate the leading edge of the first portion in juxtaposed relationship to the trailing edge of a second portion to define a reverse thrust airfoil for producing a reverse flow of air through the fan duct passage with a resultant reverse thrust action on the gas turbine engine.
