Abstract: A method for maintaining measurement accuracy of a ring laser gyroscope is disclosed. The method involves periodically measuring a path length control voltage in the ring laser gyroscope over a prescribed temperature range. When a first path length controlled by the path length control voltage deviates at least one wavelength from a nominal path length, the method detects the change in the path length as a mode shift. For each mode shift, the method applies a path length correction to maintain the first path length at a target path length over the prescribed temperature range. The method can apply a correction to a measurement signal output of the ring laser gyroscope by adjusting a calibrated scale factor depending on an actual integer number of wavelengths achieved during a mode shift.

Abstract: An aircraft control system improves system flexibility, scalability, redundancy, and separation. The system uses a "virtual backplane" architecture which maximizes system flexibility and scalability and allows easy integration of new functions. The architecture comprises four major elements: processing modules; input and output modules (i.e. I/O modules); database modules; and an aircraft wide system network. Inter module communication occurs via the aircraft wide system network thereby eliminating the need for point to point communication and making modules independent of physical location or what modular units (MUs) they are in. Predetermined periodic and deterministic broadcast techniques improve the safety and communications efficiency of the system.

Abstract: The method of making the tool, for process system identification that is based on the general purpose learning capabilities of neural networks. The method can be used for a wide variety of system identification problems with little or no analytic effort. A neural network is trained using a process model to approximate a function which relates process input and output data to process parameter values. Once trained, the network can be used as a system identification tool. In principle, this approach can be used for linear or nonlinear processes, for open or closed loop identification, and for identifying any or all process parameters.

Abstract: A direct memory access (DMA) system with a single bus architecture for controlling data transfers and storage between plural digital processors and plural Input/Output devices. Limiters are included for disabling access to the bus of a processor whose access time exceeds a predetermined time interval. A time governor is included to suppress processor access to the bus when total processor access time in a data communication cycle has exceeded a predetermined time interval. The input and output devices are coupled to the bus through interface isolation circuits that prevent faults in the input and output devices from propagating to the system to cause total system failure. An input or output device fault can only result in erroneous data being provided to a location of the DMA memory reserved for the faulted device. The DMA memory is protected by a Write-Protect Decoding Circuit that prevents processor writing into prohibited areas of the memory.

Abstract: In a method for simulation of a field of view for battle training individual images of a terrain, targets, trajectories of projectiles and sights which are digitally stored in memories (10-16), after combining and digital/video conversion in an image synthesizing device (20), are displayed on a TV monitor (TVM). The images are stored as right and left half images, and they are displayed in a half image interlaced scanning. For simulation of a stereoscopic range meter preferably the sight memory (16) stores two half images of a stereoscopic index mark in addition. The image displacement of both half images is controlled as a function of range and a viewing unit (DO, BT1, BT2) serves to feed both half images on the TV monitor (TVM) to the eyes of the spectator (FIG. 4).

Abstract: A method of synchronizing a digital timer with the frequency of a source of A.C. power to provide long term temporal stability. The timer produces internal, fine resolution, synchronization and real time timing signals from a source of clock signals. The periods of all the timer produced timing signals are integral multiples of the period of its internal timing signal.A.C. reference timing signals which are a function of the frequency of the source of A.C. power are applied to the timer. The quotient of the period of the synchronization timing signals by that of the A.C. reference timing signals is an integer "n". Once n is determined, the number of fine resolution timing signals in each synchronization period for every n.sup.th A.C. timing signal is compared with a reference value. The timing of the fine resolution timing signals is adjusted to maintain the number of fine resolution timing signals in each synchronization period at which the n.sup.th A.C.
