Patent number: 5751579Abstract: A vehicle traction control system is controlled in-part by a signal value indicative of estimated wheel torque. The estimated wheel torque value is produced within the vehicle's electronic engine control (EEC) module by summing a first value which indicated the estimated torque attributable to engine combustion and a second value which is proportional to engine acceleration/deceleration which indicates the amount of torque attributable to the inertial movement of engine and drive train masses. Before summing the two signal components, the signal which indicates combustion torque is delayed with respect to the signal indicating inertial torque by a delay interval whose duration varies with engine speed to take into account the delay between intake fuel rate changes and combustion forces as well as delays attributable to the timing of the calculations themselves.Type: GrantFiled: September 6, 1995Date of Patent: May 12, 1998Assignee: Ford Global Technologies, Inc.Inventors: Davorin David Hrovat, Daniel Scott Colvin, Michael Alan Weyburne, Ngoc Minh Tran, John Loring Yester

Patent number: 5738797Abstract: A three dimensional multi-layer circuit structure is formed by partially etching a foil having a coating. A pre-circuit is formed by providing a metal foil, applying a photodefinable photoresist to each side of the metal foil, selectively exposing and developing the photoresist leaving exposed areas and unexposed areas and, plating the unexposed areas with a second metal. The pre-circuit is placed in an etching solution and removed after the etching solution partially etches the metal foil to undercut the second metal.
