    摘要: A multi-terminal logic device. The device includes a phase change material having crystalline and amorphous states in electrical communication with three or more electrical terminals. The phase change material is able to undergo reversible transformations between amorphous and crystalline states in response to applied electrical energy where the amorphous and crystalline states show measurably distinct electrical resistances. Electrical energy in the form of current or voltage pulses applied between a pair of terminals influences the structural state and measured electrical resistance between the terminals. In the instant devices, independent input signals are provided between different pairs of terminals and the output is measured as the resistance between yet another pair of terminals. Logic functionality is achieved through relationships between the applied input signals and the measured output resistance where the relationship is governed by the effect of the input signals on the structural state and electrical resistance of the phase change material. Logic values may be associated with the crystalline and amorphous states of the phase change material or the measured resistance between a pair of terminals.

    摘要: Multi-terminal electronic switching devices comprising a chalcogenide material switchable between a resistive state and a conductive state. The devices include a first terminal, a second terminal and a control terminal. Application of a control signal to the control terminal modulates the conductivity of the chalcogenide material between the first and second terminals and/or the threshold voltage required to switch the chalcogenide material between the first and second terminals from a resistive state to a conductive state. The devices may be used as interconnection devices or signal providing devices in circuits and networks.

    摘要: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. The fluid-cooled battery pack includes; 1) a battery-pack case having coolant inlet and outlet; 2) battery modules within the case such that the battery module is spaced from the case walls and from other battery modules to form coolant flow channels along at least one surface of the bundled batteries; and 3) at least one coolant transport means. The width of the coolant flow channels allows for maximum heat transfer. Finally the batteries, modules and packs can also include means for providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to said ambient thermal condition, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

    摘要: Electrochemical and thermal hydrogen storage alloy compositions that provide superior performance, including an electrochemical hydrogen storage alloy that provides superior low temperature discharge characteristics. The alloy compositions include microstructures in the interface region that are highly porous and that include catalytic metallic particles. The microstructures include a large volume fraction of voids having spherical or channel-like shapes and are sufficiently open structurally to facilitate greater mobility of reactive species within the microstructure and in the vicinity of catalytic metallic particles. Greater accessibility to reactive sites accordingly results. The greater mobility of reactive species and/or the greater density of catalytic particles lead to faster kinetics and improved performance (e.g. higher power), especially at low operating temperatures. The microstructures may be formed through inclusion of a microstructure tuning element in the alloy composition, through control of processing conditions and/or through inclusion of etching steps in the post-formation processing of hydrogen storage alloys.
