  • Patent number: 4977529
    Abstract: A training simulator for the full-scope real-time dynamic operation of a nuclear power plant utilizes apparatus that includes control consoles having manual and automatic devices for operating simulated plant components and indicating devices for monitoring physical values in the simulated plant. A general purpose digital computer configuration is connected to the control consoles to accept input data indicative of the operated condition of the console control devices and perform dynamic real-time simulation calculations for providing output data to the monitoring devices. An instructor's console, which has control and indicating devices, is connected to the computer configuration to perform functions that include initializing and "replaying" selected operational states of the simulated plant. The majority of the control components of the simulated plant, such as valves, pumps and controllers, are simulated separately from the simulated system they control.

  • Patent number: 4648049
    Abstract: A circuit and method for a display controller especially adapted for display memories organized in arrays. The invention permits high speed modification of the contents of a display by generating the address signals of a selected linear pattern as the data block to be modified is retrieved from the display memory. For vectors, the addresses are generated in the same time as required for data block retrieval. The invention also permits calculation of the addresses of simple curves as the data block to be modified is retrieved, though calculation times typically are longer than for vectors. Modified Breshenham's algorithm is used for the address calculation.

  • Patent number: 4648042
    Abstract: The present invention is directed to a method of and and apparatus for continuously generating desired pulses during assumed successive desired pulse intervals with a very high time resolution by digitally predetermining the time values related to the start of the desired pulse intervals. These time values are divided into coarse and fine time rasters and coarse pulse intervals are generated from the assumed desired pulse intervals. The coarse pulses in the coarse time raster are generated from the desired pulses and each coarse pulse start and coarse pulse end, respectively is associated with a coarse pulse correction value. By adding the coarse pulse interval correction value to the coarse pulse correction value for the start and the end of the coarse pulse, respectively, a sum correction value is obtained and divided into a partial value associated with the fine time raster. The partial value of the sum correction value is used as a control value for a selected time delay for the coarse pulse edge shifted.

  • Patent number: 4646255
    Abstract: An aircraft gyro simulator is operable in a dynamic mode to produce simulated pitch, roll and azimuth signals as a function of control wheel commands, flight control system commands, control surface status and the stored equations of flight for the aircraft under test. In its manual mode, the simulator responds to manual control commands to individually vary pitch, roll or azimuth, thereby testing aircraft systems response. In addition, multiple channels of tracking gyro signals may be produced, with each channel having a manually controlled offset of one or more gyro signals to test aircraft employing multiple autopilot systems.

  • Patent number: 4646253
    Abstract: A method for high-precision imaging of electrical barrier layers (pn-junctions) in semiconductors by means of processing particle beam induced signals created during scanning with a corpuscular microscope, even when the electrical barrier layers are aligned perpendicularly or obliquely relative to a specimen surface. The path of the pn-junctions in cross-sections through semiconductor components may be identified with a high reliability such as within 0.1 .mu.m. Specific point (P(x,y), P(x+.DELTA.x, y+.DELTA.y), M(x,y), N(x,y), F(x,y)) is defined and particle beam induced signals generated along a scan line containing this specific point is compared with reference to particle beam induced signals generated along a further scanning line containing a point within a certain environment of the specific point first chosen with the comparison results being used to localize the electric barrier region profile.

  • Patent number: 4641246
    Abstract: A sampling digitizer system which may be expanded for the dynamic testing of high speed data conversion components is provided. The system includes latching comparators which are supplied with the waveform under test and the comparator digital output is integrated by an operational amplifier integrator and fed back to the reference input of the latching comparator to form a comparator-integrator loop. A circuit provides strobe pulses which repeatedly sample the latch enable input of the comparators at a selected time/point until the integrator feedback forces the comparator reference input to be equal to the sample value of the input signal. At this point, an equilibrium state is reached where the integrator output oscillates about the sampled value, and when the loop settles, an analog-to-digital converter reads the final value under computer command. The sample point is computer controlled through a programmable delay line.

  • Patent number: 4641253
    Abstract: A process for use of a low-cost personal computer to display video images which provide the effect of animation in synchronization with an audio program, such as voice or environmental sounds, originating independently of the computer. The computer is provided with a data base including intervals between recorded cue tones preceding the audio program, and intervals between video events to be synchronized with the audio program, all such original intervals corresponding to the original recording transport speed of the audio program. While consumer audio playback devices operate at a stable playback transport speed, it is seldom precisely the same as the original recording speed. During playback, the viewer indicates playback intervals between cue tones, for instance by tapping a key of the computer keyboard whenever a cue tone is played.
