Stretchable and elastic interconnects

The present invention relates to stretchable interconnects which can be made in various geometric configurations, depending on the intended application. The stretchable interconnects can be formed of an electrically conducting film or an elastomer material to provide elastic properties in which the interconnects can be reversibly stretched in order to stretch and relax the elastomer material to its original configuration. Alternatively, stretchable interconnects can be formed of an electrically conducting film or a plastic material to provide stretching of the material to a stretched position and retaining the stretched configuration. The stretchable interconnect can be formed of a flat 2-dimensional conductive film covering an elastomeric or plastic substrate. When this structure is stretched in one or two dimensions, it retains electrical conduction in both dimensions. Alternatively, the stretchable and / or elastic interconnects can be formed of a film or stripe that is formed on an elastomeric or plastic substrate such that it is buckled randomly, or organized in waves with long-range periodicity. The buckling or waves can be induced by various techniques, including: release of built-in stress of the conductive film or conductive stripe; pre-stretching the substrate prior to the fabrication of the conductive film or conductive stripe; and patterning of the surface of the substrate prior to the fabrication of the metal film. The stretchable interconnect can be formed of a plurality of conductive films or conductive stripes embedded between a plurality of layers of a substrate formed of an elastomer or plastic.

Airfoil shape for a turbine bucket

First stage turbine buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X and Y values are in inches and the Z values are non-dimensional values from 0 to 1 convertible to Z distances in inches by multiplying the Z values by the height of the airfoil in inches. The X and Y values are distances which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape. The X, Y and Z distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of ±0.055 inches in directions normal to the surface of the airfoil.

Shape memory alloy actuation apparatus

A miniature camera lens actuation apparatus employs an SMA actuator comprising SMA wire to move a camera lens element. To provide autofocus, the SMA actuator is heated across its range of contraction and the resistance at which the focus is at an acceptable level is stored. To combat hysteresis, there is performed a flyback in which the SMA actuator is cooled, before heating the SMA actuator to the stored resistance. The stored resistance is adjusted to combat creep caused by non-linear heating of the SMA actuator. The SMA wire has conductive material extending along on a portion of the SMA wire which extends from a member connected to the SMA wire and being in electrical connection with the SMA wire in order to short out that portion of the SMA wire to reduce creep. Additional material is applied over the SMA wire and the member to reduce fatigue.

Control of an induction motor is carried out to limit damaging arcing stress and mechanical stresses placed on the control contactor assembly and the induction motor resulting from the simultaneous or synchronous breaking and making of contactors employed to connect the windings of the motor to a power supply. Asynchronously connecting the windings to the power supply via the asynchronous or non-simultaneous closing of the contactors of a modular contactor assembly reduces the potentially damaging transient current, the associated torque oscillations, and mechanical stresses. The present invention is particularly applicable to delta motors that are started with its windings in a star or wye configuration followed by the reconnection of the windings in a delta configuration when the motor is at normal running speed.
