An analog to digital (A/D) converter system and method which provides improved resolution and reduced noise for integrating-type ADCs, including dual slope, multi slope, and sigma-delta type A/D converters. After the ramp-up interval of either a dual slope or multi slope integrating A/D converter, the ramp-down interval occurs, wherein a reference signal is then applied to the integrator to return the integrator to its original value. The clock cycles are counted while the reference voltage is applied to determine a primary slope count value. During the ramp-down interval, while the reference voltage is applied, two or more integrator voltages are measured. In one embodiment, a first integrator voltage is measured before the original value and a second integrator voltage is measured after the original value, e.g., before and after the zero crossing. The method then determines a fractional slope count based on the measured two or more integrator voltages, i.e., the fractional slope count occurring before the return of the integrator to its original value. The fractional slope count is determined by extrapolating or interpolating the return of the integrator to its original value using the measured two or more integrator voltages. The total slope count is then calculated using the primary and fractional slope counts, and the output digital value is determined using the total slope count value.

The present disclosure describes a method and apparatus for ensuring the unique zoning membership representation in a network environment. In one aspect, the members of a container may be evaluated to determine whether any are subordinate to or children of a target member of the same container. The subordinate or child members may be removed from the container's configuration. Generally following the removal of any subordinate or child members of the target member, a determination may be made as to whether the target member is a child of or subordinate to any container members remaining in the container's configuration. If the target member is determined to be subordinate to or a child of a remaining container member, the target member may be removed from the container's configuration. Consequently, redundant member entries, unintentional communication paths and the complexities associated with creating a zoning configuration may be avoided.

An aircraft flight control surface has an actuator that employs a magneto-rheological (MR) fluid for dynamically adjusting the responsiveness of the control surface. The MR fluid may be used as a primary or secondary control in the event that a primary control actuator fails. In the event of system failures associated with the primary control, an alternate level of performance may be provided by the secondary control and communicated to the overall flight control system. This permits the control surface actuator to reactively and proactively respond to changes associated with the flight control system. If the design fails, it also permits a safe mode of operation should the ability to dynamically adjust the viscosity of the MR fluid be negatively impacted. The safe mode of operation may involve a reduced level of performance.
