Abstract: A weather effects generator that generates weather data based on real-world weather data, and provides this data to a host simulator. The type of data provided and the spatial distribution of the data depend on the type of simulation. A real world database is accessed to obtain a dataspace of weather data elements, each having a location parameter and various weather-related parameters. For visual display simulators, the data elements are preprocessed to obtain color, transparency, and texture values for each data element. The preprocessed data elements are further processed to obtain a prioritized display list of those data elements that correspond to field-of-view data provided by the simulator. Each data element in this list is assigned a graphics primitive that can be rasterized in accordance with the color and transparency values. Simulators other than visual display simulators provide location data and receive data representing the weather effects at that location.

Abstract: A method and system for controlling transitions between attitude command/response and rate command/response in an aircraft control system wherein the transfer function for a generic second order system is developed at current operating conditions and a predetermined constant damping. During a transition, trim follow-up frequency is changed progressively to coincide with the desired bandwidth, thereby effecting a pole-zero cancellation and converting the transfer function to that of a rate command/response system. Actuators, responsive to signals produced by the control, change aircraft parameters by altering the position of the main rotor and tail rotor control system in accordance with pilot input signals.

Abstract: The assured-integrity monitored-extrapolation (AIME) navigation apparatus selectively utilizes measurements provided by ancillary sources at periodic intervals in determining the state of the platform on which the apparatus is mounted. The measurements have attributes which are measures of quality, quality being a measure of the usefulness of the measurement in accurately estimating the state of a platform. The AIME apparatus makes its selection of measurements for state determination on the basis of estimates of the values of these quality attributes. The determination of the quality of a time sequence of measured values of a particular quantity requires an evaluation time for its accomplishment. The AIME apparatus therefore determines the platform's state in two phases.

Abstract: A logic synthesis unit generates configuration data of a virtual logic circuit composed of virtual elements, or logic gates each of which carries only a functional definition, in order to realize a logic circuit functional description fed through an input unit. A logic transformation unit, referring to a standard cell library, performs the allocation of real elements for implementation to respective virtual elements to transform the virtual logic circuit into a real logic circuit having the same function as the virtual logic circuit. Then the logic transformation unit, referring to a timing analysis unit, selects a particular real element with a smallest driving capacity from among the real elements in the library performing the same function as an object virtual element and satisfying both fan-out restrictions and delay constraints, and allocates the real element thus selected to the virtual element.
