Abstract: A number of program modules (32, 34, 36) are sequentially controlled by a procedural user interface (PUI) (38) and an operating system (40) to perform tasks. Transfer of files or other data entities between the modules (32, 34, 36) and a storage (13) is seamlessly integrated by a sequential information integration service (SIIS) (50). For reading a file from the storage (13), the PUI (38) or the operating system (40) generates a read command including a filename designation which can include a pathname, complete filename or wildcard characters. The read command can also include one or more arguments such as a user or group access code and an error message to display if the required file is not found. In an automatic mode, the service (50) automatically selects the most recent file corresponding to the filename designation and arguments, or displays the error message if a file meeting these criteria is not found. In a manual mode, the read command includes a manual selection argument which controls the service (50) to display a list of files (64) corresponding to the filename designation and arguments in a dialog box or window (60) for manual selection. The read command can further include a prompt message (62) for display in the window (60) together with the list of files (64).

Abstract: An integrated circuit assembly includes a silicon thin film circuit bonded to a substrate of a material selected to provide the assembly with an effective thermal expansion characteristic that approximately matches that of another device, such as HgCdTe detector. The assembly, when bump bonded with the device, is resistant to failure when subjected to thermal cycling. A first method for manufacturing the assembly includes the steps of forming a desired circuit in a thin layer (12) of silicon on a silicon substrate of a bonded silicon wafer. The thin silicon layer including the circuit is then bonded to the selected substrate material (24). Thereafter the silicon substrate is removed and the resulting assembly may be mated to the device (36). A second method employs a two stage transfer technique wherein the processed thin silicon layer is bonded to a first, temporary substrate; the silicon substrate is removed; a second, permanent substrate is attached; and the first substrate is removed. The second substrate is comprised of a material selected for providing the assembly with a coefficient of thermal expansion that is matched to the material of the device.

Abstract: A radar system including a Kalman filter that processes radar return signals to produce position, velocity, acceleration, gain and residual error output signals, and a post-processor that processes these signals in accordance with a track filter bias estimation procedure. The procedure computes bias estimates and revised position, velocity and acceleration output signals that are corrected for bias error. The revised output signals are coupled to the radar system to track a target. The track filter bias estimation method computes bias estimates in accordance with relationship (I) where Res, K1/K2, R and T denote the residual, gains, range, and filter cycle time, respectively, and the tilde indicates a sample averaging. The present invention also provides for improved maneuver detection by implementing an acceleration estimation algorithm used to track a maneuvering target. The present invention is applicable in all fields and areas where estimation using Kalman filters is used.

Abstract: Overhead head-up display systems that has an image display source located above the operator of a vehicle. The display source may be mounted off-axis or in-line with the operator's forward viewing direction depending on the vehicle passenger compartment configuration. The image display source and a spherical (or aspheric) optical combiner are used to display sensor and communications data at an optimum viewing location. A roof mounted overhead head-up display is ideal for retrofitting a vehicle passenger compartment with a virtual image display because of the simplicity and flexibility of its design. The present invention is particularly useful as a head-up virtual image display for use in a vehicle that displays instrumentation information, and provides a vehicle head-up dynamic instrument display that provides for a virtual image instrument display at or ahead of the windshield of the vehicle. The present invention requires no mirrors and uses an optimized optical combiner surface for improved image clarity and brightness. The image display source location is ideal because there is generally ample room in the overhead area of the passenger compartment to mount equipment without interfering with an operator's field of view in any direction or his or her freedom of movement. The overhead mounted configuration requires minimal modification to the existing passenger compartment of any vehicle. The optical combiner may be roof, dashboard or windshield mounted whichever is most convenient.

Abstract: A method of tracking an object in the Doppler dimension that provides for improved imaging. The method tracks the centroid of the object's Doppler and smooths out noisy estimates of its phase history. The tracking and smoothing combine to improve tracking performance and image quality. Doppler signals are generated by a coarse Doppler tracker that removes translational motion of the object. Pulse pair processing produces an estimate of the Doppler centroid of the object. For each pair of adjacent pulses, pulse pair processing is applied to individual range bins, and the outputs are combined to estimate the Doppler centroid of the object at that particular time. A low pass filter is used after pulse pair processing to smooth out phase increments. Phase increment smoothing then filters the output signals from the filter with a smooth curve, such as a second-degree polynomial. Phase recursion then produces a phase history. The recursive phase history is differenced with updated, appropriately delayed phases. The difference phases are compensated from the radar return from the coarse Doppler tracker. Fast Fourier transform processing then produces a Fourier transformed image. The output from the filter is also processed to update the phase and the phase updated signals are fed back to the coarse Doppler tracker. The phase updating integrates the output of the filter to update the phase history of the object based on phase increments derived from the filter. The phase update is also delayed in order to match these phases in timing with those from the phase recursion step.

Abstract: An analog system (100) of measuring the difference in time of occurrence of events is described. The method uses two coherent oscillators (110, 116) of the same frequency which start with predetermined phase when each of the events are detected. The phase difference of the oscillators (110, 116) is a measure of the difference in the time of occurrence of the two events.

Abstract: A munition incorporating a miniature transmitter (25) and a piezoelectric power supply (45) which converts a portion of the kinetic energy of the projectile (20), upon impact, into radio frequency energy and radiates that energy into space. The transmitter (25) can be made in suitable sizes to fit various calibers of ammunition. Different caliber ammunition can be made to radiate different frequencies. The transmitted RF energy allows the point of impact of the projectiles to be located with a high degree of precision. This type of munition may be used in the scoring of air to ground gunnery in training environments by receiving the RF energy at several known locations and determining the point of impact using time of arrival or angle of arrival techniques. Frequency discrimination allows simultaneous scoring of multiple weapons from the same aircraft or from multiple aircrafts. The munition may be employed in tactical applications by allowing the fall of fire to be located and adjusted.

Abstract: A waveguide filter (22, 24) is incorporated into a cavity resonator (20) for a free-electron laser or the like by coating a material layer (24) on the inner peripheral surface of a hollow waveguide member (22). A high pass filter configuration is provided when the conductivity of the material layer (24) is higher than that of the waveguide member (22), such that electromagnetic signals having wavelengths longer than the skin depth of the material layer (24) pass into and are affected by the lower conductivity waveguide member (22). Reversing the conductivities produces a low pass filter configuration in which signals having wavelengths shorter than the skin depth are affected by the material layer (24). A bandpass filter configuration is provided by adding an additional material layer (32) of low conductivity to a high pass filter, whereas a band exclusion filter configuration is produced by adding an additional material layer (32) of high conductivity to a low pass filter.
