A solenoid coil inverted within a flux casing has at least one lead wire extending through a flux ring mounted in an end of the flux casing. The coil is coupled to a circuit board or overmolded lead frame which is positioned adjacent to a valve body with a solenoid valve sleeve extending through the circuit board or lead frame into the coil. A flexible coupling allows the coil to move relative to the circuit board or lead frame.

A hydraulic valve body for an electro-hydraulic control unit forms a heat sink for the control unit electronic components. The control unit can be included in an anti-lock brake system.

A virtual image display management system using a head-up display that improves the ability of an operator of an automobile, or other equipment, to focus on primary functions, such as vehicle operation, while providing secondary information within the operator's primary visual field without requiring the operator to refocus. The present virtual image display management system integrates one or more secondary function displays into one reconfigurable virtual image head-up display. Several secondary functions are displayed sequentially using analog/digital symbology, icon representation, alphanumeric text or static/motion picture format. The operator may select secondary functions to be monitored, the display format, and the data acquisition intervals. A reconfigurable virtual image display processor accommodates more sophisticated sensor and communication functionality without penalizing efficiency and safety of the operator's primary functions. The present system integrates, interprets, selects and displays data derived from multiple sensors and communications systems at an optimum visual location within the operator's primary field of view. By displaying data in this fashion, an operator can vigilantly perform critical system functions while being kept well-informed of vehicle performance data, communication data and other useful functions and information.

A multilayer flexible circuit for sensing physical properties of a structural surface 12 capable of surviving exposure in harsh environments through the use of isolation materials 70 disposed within the flexible circuit 10.

Conformal circuit with harsh environment isolation materials

A strain, crack and acoustic emission conformal structural health monitoring circuit with integral preprocessor and provisions for connectorization to a central processing system includes a strain gauge (11) having crack sensing traces (21), (23), and (25) sandwiched between a bottom layer (13) and a top layer (39). Strain gauge (11) is attached to an aircraft structural surface (51) to be monitored. Successive alternating layers of interconnecting sheet layers (61) and dielectric layers (63) joined by successive layers of non-structural adhesive (65) are added sufficient to effectively attenuate any stress forces, and forces directly from the strain and cracks, from traveling upward from the aircraft structural surface (51). A metalization layer (47) tops the successive layers and supports an integrated circuit (43) which may be multi-chip hybrid package, discretely packaged components or conformally coated chip/circuit assemblies, and provides a means of interconnect to and protection from the ambient environment.
