  • Patent number: 9939624
    Abstract: An inspection system that is effective to collect images of a part under inspection. This inspection system includes (a) a three axis linear motion stage; (b) a rotary fourth axis stage configured to hold and rotate an object to be inspected. This rotary fourth axis stage is mounted on the three axis linear stage; (c) a fifth axis camera and optical system mounted to one of the axes of the three axis linear motion stage. This fifth axis camera has an optical axis substantially parallel to the axis of linear motion; (d) a 45 degree mirror configured to bend the optical axis of the fifth axis camera by 90° to point towards the object; and (e) a motor configured to rotate the mirror over a range of angles to obtain a fifth axis of viewing orientation.

  • Patent number: 9823101
    Abstract: A method for the rapid optical inspection of stents is described wherein a stent is mounted on a mandrel with optical properties suitable for machine vision inspection of the stent is conveyed to a first inspection station containing a camera and illumination light source. A driving member securely contacts the mandrel and the stent is rotated in view of the inspection camera. The stent is then transferred to a second location for further operations. A unique identification tag is associated with each mandrel and tracks the location of the stent through the inspection process.

  • Publication number: 20160231555
    Abstract: A first borescope for viewing an interior surface of a cylindrical article has an image conducting tube with a beamsplitter cube adjacent a distal end of the image conducting tube. When the article allows light to pass through it, the borescope has a light source effective to provide light illuminating the inner surface from an opposing second side of the beamsplitter cube. A second borescope, useful when the article does not permit light to pass through has an image conducting tube with a reflector. A plurality of optical fibers form a light conduit mounted to optics effective to transmit light from a proximal end of the image conducting tube to the distal end, whereby the light exits through an annulus at the distal end.

  • Patent number: 7474984
    Abstract: A combination of a racecourse and a plurality of racing vehicles where the racecourse has a predefined path defined by at least one gate. This gate further includes a unique identifier. Each of the plurality of racing vehicles has a sensor capable of detecting the unique identifier and the sensor is further coupled to a logic circuit and to a transmitter. A scoreboard has receiver to receive information from the transmitter and display that information, such as lap speed and ranking, according to a desired format. Alternatively, the unique identifier is mounted to the racing vehicle and the sensor to the gate.

  • Patent number: 6879403
    Abstract: A system for measuring the spatial dimensions of a three-dimensional object employs a lens and at least two detectors. The combination of which defines two or more object planes. The combination of the lens and the detectors define an optical axis that is normal to the object planes and passes through a focal point of the lens. At least a first and a second photodetector are optically aligned with the object through the lens. The first and second photodetectors or array of detectors are further parallel with the surface but have differing elevations relative to that surface. In addition, the first and second photodetectors are capable of motion relative to said object. Electrical output from the first and from the second photodetectors is provided to a processor that determines a distance of the object from the lens and thereby a height of the object. This system is particularly suited for measuring the spatial dimensions of solder balls mounted to a surface of a ball grid array (BGA) electronic package.
