    Abstract: The present invention is a suspension unit having active and passive modes, for a vehicle suspension system, having a fluid source for providing a pressurized fluid. The suspension unit comprises a fluid actuator, a fluid spring, and fluid connecting means for coupling the fluid source to the fluid actuator. The suspension unit further includes mode selection means coupled to the fluid connecting means for responsively selecting the mode of the suspension unit, first valve means coupled to the mode selection means for providing fluid communication between the fluid spring and the fluid actuator in the active mode, and second valve means coupled to the fluid connecting means between the fluid spring and the fluid actuator in the active mode for providing fluid communication between the fluid spring and the fluid actuator in the passive mode.

    Abstract: A technique for and structures for camouflaging an integrated circuit structure and strengthen its resistance to reverse engineering. A plurality of transistors are formed in a semiconductor substrate, at least some of the transistors being of the type having sidewall spacers with LDD regions formed under the sidewall spacers. Transistors are programmably interconnected with ambiguous interconnection features, the ambiguous interconnection features each comprising a channel formed in the semiconductor substrate with preferably the same dopant density as the LDD regions, with selected ones of the channels being formed of a conductivity type supporting electrical communication between interconnected active regions and with other selected ones of the channels being formed of a conductivity type inhibiting electrical communication but ambiguously appearing to a reverse engineer as supporting electrical communication.

    Abstract: An ionic flame monitor. The flame monitor has a flame rod that produces an ionization current when the flame rod is immersed in a flame and excited by a voltage. The ionization current has a DC component and an AC component each dependent on the intensity of the flame, and a flicker frequency. The flame monitor also has a computing device that is responsive to signals representative of the flicker frequency, and the AC and DC components of the ionization current for determining the existence of the flame.
