Patent EP-0409310-A2 (EP)
Inventor: IMME MARTIN WALTER
IPC: G06T7/181
Filed: 1990-07-09
Abstract: Conventional methods for determining edges in images operate with linear or non-linear but in any case two-dimensional operators in a filtered image. During this process, however, some edges or edge sections are not detected so that the edges have gaps and due to the filtering, the edge found is frequently offset by a certain amount compared with the actual edge in the unfiltered image. According to the invention, the image matrix of the filtered image is therefore scanned in four different directions, namely column-by-column and line-by-line and in both diagonals, and local maxima and minima are determined in all these scanned pixel sequences. Between these maxima and minima, the actual grey scale variation in the unfiltered image is then approximated by a function having a turning point, for example a sine function, for example in accordance with the method of least error squares, and the turning point then specifies a point of an edge. Thus, interruptions in the edges and displacements compared with the actual image are avoided.

Abstract: An acoustic borehole logging tool traverses a fluid-filled cased well with an acoustic energy transmitter. Pressure waves created in the well fluid by the transmitter generate tube waves in the well casing. A closely spaced receiver detects tube waves that have travelled along the cased wellbore and been reflected by fracture interfaces. These reflected tube waves are recorded and used to identify the top and bottom of any fracture interval in the formation behind the well casing. This method can also be appoied to determination of the effectiveness of a hydraulic fracturing operation in a subsurface formation behind a well casing.

Abstract: Novel polyester molding compositions are disclosed which exhibit unexpected water absorption properties. The compositions of the invention include a polyester base resin (which preferably is a linear poly(alkylene) terephthalate, e.g., poly(butylene) terephthalate, or a copolyester elastomer having long chain ester units derived from corresponding long chain glycols of molecular weight 600-6000 and a carbon to oxygen ratio of greater than 2.5), and a copolyester elastomer having a multiplicity of long and short chain ester units, wherein the long chain ester units are derived from corresponding long chain glycols of molecular height 400-3500 and a carbon to oxygen ratio of between about 2.0 to 2.4. Since the polyester molding compositions of this invention exhibit less water absorption, they may satisfactorily be employed to form parts where low swelling is a desireable physical attribute (e.g. as movable parts of a component having critical spatial tolerances).

Abstract: An automatic method and apparatus for the repair of circuit shorts and near-shorts present in narrow bridges (6, 13) or remnants of bridges between circuit lines (5). By applying a voltage across a pair of lines, certain electrical phenomena take place at the area of the short or near-short. The electrical phenomena thus generated induce a localized etching in either a gas-phase or liquid-phase medium depending upon which embodiment is used. The circuit lines are classified into four groups so that no adjacent lines belong to the same group. All lines in a group are connected to one of four separate electrical conductors. Each conductor is connected to one phase of a four phase ac source (7a). All the shorts and near shorts on a circuit are repaired simultaneously and automatically in a single operation without having to locate the shorts and near shorts.

Abstract: A reference delay generator includes a delay unit (VCD) having a plurality of delay elements (E) which are cascaded and respectively have variable delay times. The delay unit receives a reference signal (ECK) and generates a delayed signal (DCK) which is a delayed version of the reference signal. A control part (PDD, CT; PLL) detects a phase difference between the reference signal and the delayed signal and generates a control signal (Vc) which sets the phase difference to an integer multiple of 90°. The control signal is applied to the delay elements, so that the delay times of the delay elements are changed on the basis of the control signal. The control signal is used for, for example, controlling a delay circuit (DLC) which includes a plurality of delay elements identical to those of the delay unit.

Abstract: A non-intrusive vibration monitoring apparatus and method uses ultrasonic transducer means (46, 50) to transmit and receive ultrasonic pulses to and from a vibrating internal part (22, 66) of a body (20, 72). A record of pulse emission and reception times is made by recording means (16, 18), and the recorded data is digitally filtered to provide a visual display (62) from which quantitative measurements may be made. Commercial ultrasonic instruments may be used together with digital signal filtering and analysis techniques to enable quantitative detection of vibrations as small as 1 x 10⁻³m (0.04 inch) peak-to-peak. The system may be used for in-service vibration monitoring of internal components of check valves, pumps, nuclear reactors, steam generators and heat exchangers, especially when the vibration frequency is too low for quantitative analysis by accelerometers and when the strain induced is too low for strain gauge analysis.

Abstract: Disclosed is a method and apparatus for generating a test sequence to test a fault in a digital circuit. According to this method and apparatus, when a fault propagation process for a fault, for which a test sequence is generated is not successful, at least a segment of a path to propagate the effects of the fault is memorized as illegal information. And the fault propagation process is restarted for the same fault without selecting the illegal information. Hence, the chance of a successful fault propagation process is increased, which leads to the improvement of the fault coverage. 
     In addition, according to the apparatus and method, it is detected whether a state transition goes into a loop (i.e., two identical states exist) in the state initialization process and then the process is restarted by defining the state caused the loop as an illegal state. Hence, the chance of a successful state initialization process is increased, which leads to the improvement of the fault coverage.

Abstract: A computer-controlled graphics display system using object-based representations of the displayed objects (47,48,49), and cooperating with a user-operated motion-sensitive input device. A powerful user interface technique called "wiping" is described. This allows selection by the user of target objects to be acted on by accessing an applicator and sweeping the applicator over the display (11). Selected objects are determined by selection criteria including spatial intersection of the applicator sweep stroke (50) with the displayed object, and time of object creation. The effect on the selected objects is on the entire object and is determined by an operator associated by the user with the applicator, such as object grouping, deletion, coloring, uncoloring, thickening, or object size relocation.

Structural defects in inorganic objects under test are identified in real time during the manufacturing process are corrected when feedback signals are generated from the electronic image data generated during the nondestructive test process.
