摘要： An apparatus for testing digital logic circuits without a computer and associated software employs a pseudorandom stream of input data to produce an unstructured output data stream which is analyzed by an efficient data collector and analyzer. Test signal generation is implemented by a pseudorandom number generator (13) and a pseudorandom clock/reset generator (14) (15) while the resulting test data at the output terminals of the device under test (16) is analyzed by a cycle redundancy code checker (23). Fault localization is realized, with selectable localization and manual probe modes and circuitry is provided for an efficient self-test mode.

摘要： The present invention is an inertial rate of turn sensor of the vibratory type employing force feed back techniques for maintaining the free end of a cantilever (16) in a nulled lineal path (z), constant with respect to the casing (5) of the instrument. A piezoelectric transducer (25) provides the driving force. The current, applied to the piezoelectric transducer (25) required to maintain the constant lineal path is then a measure of the amplitude of the rate of turn of the case (5); and the phase sense of that current defines the sense of rotation of the case (5) and therefore of the object to which it is attached.

摘要： A complete frame of radar data is stored in real time in the memory (20) addressed by the converter (21) in accordance with antenna azimuth. PPI display (43) includes a rapid non-real radar time rotating scan by deflecting the beam along the azimuth sweeps thereof under control of X-rate and Y-rate signals provided for each sweep. Additionally, concatenated straight line strokes for synthetic symbology are displayed on the PPI display (43) under control of X-rate and Y-rate signals. The X-rate and Y-rate signals are applied sequentially to X and Y binary multipliers (49, 50) under control of the pattern memory (42) in order to generate clock signals at a frequency proportional to the rate signals. The clock signals are then applied to X and Y position counters (53, 54) respectively for generating the X and Y deflection signals via the digital-to analog converters (55, 57).

摘要： The test device is an electrolytic apparatus for the simultaneous non-destructive testing of the integrity of pluralities of circuit boards for continuity and anti-continuity or short circuits, including such circuit boards (23, 23a) as employ multi-layer or multi-level interconnection wiring, whether it be printed wiring or screen printed or thermally deposited circuits. Transient electro-deposition of one ion from an alkali halide water solution temporarily modifies the optical reflectivity of exposed circuit terminals (100) or metal parts of the circuit boards under test in a characteristic and easily recognized manner according to the continuity status of the associated circuit paths (104, 106).

摘要： Symbology is written on a radar plan position indicator display (202) with a rotating beam deflection field generated, for example, by a rotating yoke (201). The symbology is written in radar real time as the system generates the radially oriented range sweeps (10). The displayed radar range is quantized into a predetermined number of range increments and digital data representative of the symbology to be written are inserted into a shift register (33) which is clocked in synchronism with the range sweeps to provide interleaved digital data to the video input of the display thereby writing the desired symbology in real time as the range sweeps provide the normal radar display. The normal radar video data is combined (39) with the symbology data so that the symbology and normal radar returns are simultaneously written in real time. A portion of the symbology generating apparatus (Fig. 2) provides a manual acquisition marker comprising a range ring (12) and an azimuth geometric figure (13). The symbology writing apparatus also includes a portion (Fig. 4) for providing alpha-numeric or other localized symbology (Fig. 3).

摘要： L'etat binaire de chaque cycle d'un signal d'entree module biphase est detecte par une bascule 'D' (17) lorsqu'elle est synchronisee par un signal de reference genere localement. Lorsque l'etat binaire du signal d'entree possede une premiere valeur a la synchronisation, le signal de reference passe par une premiere porte OU exclusif (5) inchangee. Lorsque l'etat binaire du signal d'entree possede la valeur opposee, le signal de reference est inverse par la meme porte OU (5). La sortie de la premiere porte OU (5) et le signal d'entree sont appliques sur une seconde porte OU exclusif (1) pour produire un train d'impulsions ayant un cycle de travail indiquant l'erreur de phase entre le signal d'entree et le signal de reference. Ce train d'impulsions est filtre et utilise pour ajuster la phase de l'oscillateur de reference (13) jusqu'a ce que l'erreur de phase soit eliminee et le circuit en equilibre. L'etat binaire de la bascule (17) indique l'etat binaire du signal d'entree.

摘要： Guidance system used in laying undersea pipe or cable (3) from a pipe-laying vessel (1) when radio transmissions are unreliable. The system processes parameters derived from sensors (80, 88) normally aboard a pipe-laying vessel and sensors (83) cooperating with active winches (52) applying tension to the several anchor lines (12). The vessel's pitch, roll and heading angles are supplied from gyrocompass (88) and vertical gyroscopic instruments (80). Anchor line (12) elevation and azimuth angles with respect to deck coordinates are yielded by conventional angle pick offs (56, 60) associated with fairlead devices, as are the line axial tension and the length of anchor line paid out. Initial conditions, including the initial position of the vessel (1), are easily obtained in the usual manner (106). From certain of these parameters, the invention derives intermediate anchor line parameters for use in computing fairlead motion (93). The intermediate data is used to compute compensated fairlead motion data by first computing apparent fairlead motion from anchor line tension changes (110). This version of fairlead motion contains undesired terms due to apparent fairlead motion caused by anchor line length changes and also due to actual fairlead motion caused by vessel attitude changes. Therefore, second and third computations (112, 117) are made of the contributions of the latter effects. This is done so that apparent fairlead motion due to anchor line length change and actual fairlead motion due to vessel attitude change may be subtracted (114) from the measure of apparent fairlead motion as calculated from anchor line tension change, yielding the desired compensated fairlead motion value free of significant disturbing components (115). An estimated value of vessel position change is then obtained by a least squares estimation (130) involving these fairlead motion terms. Correction of vessel position (133) then follows by cooperative operation of the winch and thruster assemblies (52).
