  • Publication number: 20190170614
    Abstract: An analysis cartridge the includes a main body portion and a filter assembly. The main body portion includes an upper portion that defines an upper chamber and a lower portion that defines a fluid chamber. The filter assembly is movable along a filter assembly path between a first position and a second position. The filter assembly has an opening defined therethrough. In the first position, the opening partially defines the upper chamber and in the second position the opening partially defines the fluid chamber.

  • Publication number: 20190163992
    Abstract: A retroreflectivity measurement system comprises a light source arranged to project light across a traffic lane during a measurement run, the light being limited to a particular portion of the visible light spectrum. A camera is selectively sensitive to this light to provide first filtered images and separately selectively sensitive to light at a portion of the spectrum not including the particular portion to provide second filtered images. A controller obtains sequences of first and second filtered images during the measurement run, and identifies within the sequences of images an illuminated road marking; determines a first intensity of the marking from a first filtered image, and a further intensity of the marking from the second filtered images; estimates an ambient intensity of the marking, by applying a scaling factor to the further intensity; and determines a retroreflectivity of the marking as a function of the first and estimated ambient intensities.

  • Patent number: 10162363
    Abstract: A system and method is provided for identifying an object along a road, where the object may be represented by a bounding box, and projecting a set of obstacle points within the bounding box corresponding to the identified object. In one aspect, a two-dimensional plane oriented perpendicular to a direction of the movement of the vehicle may be identified. In another aspect, the areas of the plane that may be occupied based on the set of obstacle points may be determined to generate a contour of the identified object. Thereafter, the height profiles of the identified object and the vehicle may be determined and identified, respectively. Based on the height profiles, a minimum clearance may be determined.

  • Patent number: 9196164
    Abstract: Aspects of the disclosure relate generally to notifying a pedestrian of the intent of a self-driving vehicle. For example, the vehicle may include sensors which detect an object such as a pedestrian attempting or about to cross the roadway in front of the vehicle. The vehicle's computer may then determine the correct way to respond to the pedestrian. For example, the computer may determine that the vehicle should stop or slow down, yield, or stop if it is safe to do so. The vehicle may then provide a notification to the pedestrian of what the vehicle is going to or is currently doing. For example, the vehicle may include a physical signaling device, an electronic sign or lights, a speaker for providing audible notifications, etc.

  • Patent number: 7702547
    Abstract: Systems, methods, and computer program products for presenting, on a statement associated with a financial transaction instrument, an amount of interest avoided during a statement period. A first interest amount is computed for the statement period according to a first interest calculation method, the first interest amount being an interest amount actually billed to the transaction instrument account holder. A second interest amount is computed for the statement period according to a second interest calculation method. An amount of interest avoided for the statement period is computed by taking a difference of the first interest amount and the second interest amount. The amount of interest avoided for the statement period is displayed on the statement, whereby the holder of the transaction instrument is informed as to the amount of interest avoided by use of the first interest calculation method, rather than the second interest calculation method.

  • Publication number: 20070290695
    Abstract: Current testing/measuring apparatus 10 comprises a flexible member 12 having a first end 14 and a second end 16. In use, the flexible member 12 is arranged to locate around a conductor 11 carrying a current to be measured. In particular, the current measuring apparatus 10 comprises a Rogowski coil. The ends of the flexible member 12 are coupled together in use but a gap is created between the ends. This distance can generate errors in the current measurement and the present invention provides compensation means 28 in the form of a compensation windings. The compensation windings comprise a planar spiral conductor provided on a printed circuit board to compensate for the separation distance between the first end and the second end.

  • Publication number: 20070237388
    Abstract: A classification system or classifying images of solder joints has a two-sided classifier to which query cases are presented. It can operate in an environment without task-specific counter-concept cases (“bad examples”) because it filters a library of general counter-concept cases to provide a refined set of counter-concept cases. The filtering is performed by a one-sided classifier, which uses a base of task-specific concept cases to perform the filtration.

  • Publication number: 20070177789
    Abstract: A solder paste inspection machine carries out the steps of automatically generating inspection data for solder paste deposits, automatically determining a squeegee direction of travel for said paste deposits. It associates the squeegee direction with the inspection data, and feeds the inspection data back to a solder paste printer with an indication of squeegee direction. The direction is determined from three-dimensional range maps, the direction of squeegee travel being in the direction of upward slope.

  • Publication number: 20070043722
    Abstract: A classification system automatically generates an indication that a training feature vector case is a pollutant based on a mis-labelled reference image. It excludes the case from the set, builds a k-nearest neighbour confidence classifier, and then classifies the case using this classifier. The case may be marked as suspect if its classification does not match what is determined, or if they do match, if the confidence level is below a threshold. The system can automatically remove or re-label all suspect cases.

  • Patent number: 7180606
    Abstract: A machine vision system (1) has two laser sources (2, 3) to illuminate a solder deposit from both sides for comprehensive coverage without occlusion. The camera (4) has an FGPA (32) programmed to define a subset of the sensor array (20) as a region of interest to be processed for each laser source (2, 3). This reduces the amount of data transfer and processing required. The image line (31) is dynamically maintained in the region of interest by adjustement of camara Z position according to warp of the substrate (S).

  • Patent number: 7171037
    Abstract: A display for use in a printed circuit board inspection system for inspecting objects on a printed circuit board is capable of displaying a greater-than-two dimensional image of the shape of the surface of an object resident on the printed circuit board in at least two dimensions. The image of the object is generated based on optical imaging of the object under different illumination configurations.

  • Publication number: 20060291715
    Abstract: Solder fillets are inspected post-reflow by illuminating firstly from one side only along a dimension through a row of components. Only pixels arising from light received normal to the joints on that side are analysed. There is then illumination from the opposite side and corresponding image analysis normal to the right side fillets only. This avoids noise arising from reflections from a fillet across to the opposite fillet of an adjacent component.

  • Publication number: 20060221406
    Abstract: Images are captured of linear illumination with improved identification of lines and elimination of noise. A most probable line of multiple lines is identified as the one which is widest, and two parallel lines in proximity are regarded as one if their separation is two or one dark pixels. There is an upper line width limit, to eliminate blooming.
