摘要:
A method for processing a low dielectric constant material includes dispersing an additive material in a porous low dielectric constant layer, fabricating a desired electronic structure, and then removing the additive material from the pores of the low dielectric constant layer. The removal of the additive material from the pores can be accomplished by sublimation, evaporation, and diffusion. Applications for the low dielectric constant layer include the use as an overlay layer for interconnecting a circuit chip supported by a substrate and the use as printed circuit board material.

In fabricating wafer scale integrated interconnects, a temporary or permanent dielectric layer and a pattern of electrical conductors are used to provide wafer scale integration or testing and burn-in. A resist can be used to cover the areas of IC pads on the wafer while the remainder of the pattern of electrical conductors is removed to provide for repair of the wafer scale integration structure. The pattern of electrical conductors may be configured so that the conductor lengths between at least some sub-circuits on a plurality of wafers are substantially electrically equal for signal propagation purposes; an additional wafer may be laminated to the wafer using an adhesive; controlled curfs may be cut into the wafer; and the wafer may be interconnected to an interface ring.

A control system includes a controller and an energy management system. The controller is onboard a vehicle that includes motors and an onboard energy storage device that powers the motors. The energy management system calculates estimated electric loads of powering the motors over one or more segments of a trip according to designated operational settings of a trip plan. The energy management system also determines a demanded amount of electric energy for powering the vehicle based on the estimated electric loads. The demanded amount of electric energy is based on a stored amount of electric energy in the onboard storage device. The energy management system communicates the demanded amount of electric energy to one or more of plural wayside stations disposed along the route so that the wayside stations have sufficient electric energy to charge the onboard energy storage device with the electric energy to meet the estimated electric loads.

A control system includes an onboard controller, a location determination system, and a speed sensor. The controller identifies a designated area along a route that includes a downhill section, an airflow restricted area, a banked section, a section to be cleaned, an adverse environmental area, an adverse vehicular condition area, and/or a section where travel is restricted. The designated area is associated with an operating rule that requires the vehicle to travel at least as fast as a lower speed limit. The location determination system monitors actual locations of the vehicle as the vehicle travels along the route. The speed sensor obtains speed data representative of an actual velocity of the vehicle. The controller restricts control of the vehicle such that the actual velocity of the vehicle is at least as fast as the lower speed limit of the designated area when the vehicle is in the designated area.

Methods and systems are provided for operating an engine, the engine coupled to a traction alternator for vehicle travelling. In one example, the method includes, in an off-highway vehicle running mode of operation, supplying current from the traction alternator to a traction motor via a traction inverter to propel the vehicle, and, in a starting mode of operation, supplying stored energy from a first energy source and a secondary energy source to the traction alternator to start the engine.

A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.
