  • Patent number: 10391543
    Abstract: A single piece pulsed flow wing assembly method providing for horizontal wing manufacture is accomplished using synchronized automated vehicles guided in a predetermined manner to move and, locate wing structure in a plurality of assembly positions. Multi-axis assembly positioning systems (MAPS) are used at each assembly position to support and index components in the wing structure and determinant assembly techniques are used for indexing of the components. Modular automated manufacturing processes employing magnetic assembly clamping, drilling, fastener insertion, and sealant application are employed.

  • Patent number: 6776619
    Abstract: Apparatus and method for refreshable tactile display are disclosed, the apparatus being preferably embodied as a rotating-wheel refreshable Braille reader. The reader includes a housing having a reading aperture with a rotatable wheel assembly maintained therein so that a display surface of a rotating wheel passes the reading aperture. The wheel has endless rows of openings defined therethrough to the display surface, a pin held in each opening and freely movable therein. Actuators, at least equal in number to the rows of openings but substantially fewer in number than the openings, are held at a static location relative to the wheel for selectively moving pins in the rows so that Braille characters are arrayed at the display surface after passing the static location. Braille characters are thus streamed across the reading aperture of the housing.

  • Patent number: 6692255
    Abstract: A refreshable Braille reader apparatus and method are disclosed, the apparatus preferably utilizing a rotating cylinder having endless rows of openings defined therethrough to a display surface with a pin held in each opening and freely movable therein. Static actuators at least equal in number to the rows of openings through the cylinder are maintained at a station adjacent to the surface of the cylinder, and are configured and positioned so that the pins are selectively contactable at either of their ends by different ones of the actuators during cylinder rotation in either forward or reverse direction thereby selectively positioning first ends of the pins relative to the surface of the cylinder to allow streaming of Braille text across a display area in either forward or backward order depending upon selected direction of cylinder rotation.

  • Patent number: 5999519
    Abstract: A millimeter wave link provides a means for easily transporting multiple high speed data channels, in excess of 100 Mb/s, a distance of up to 10 km, without requiring elaborate modulators and demodulators. This invention also provides fast setup, versatility, and is portable, which makes it desirable for field use. In addition, it can be set up for long term high speed data collection in a virtually permanent environment. The unidirectional link of the present invention is intended for use in experimental data collection systems, where portability, ease of setup and high speed data transfer are required. University environments as well as independent research and development institutions can benefit significantly from its use.

  • Patent number: 4934220
    Abstract: A ratchet mechanism in a reversible ratchet wrench is sealed by novel means. The sealed reversible ratchet wrench includes a ratchet body having a head portion and a handle portion. The head portion has a head cavity formed therein, which cavity receives the ratchet mechanism. The ratchet mechanism communicates exteriorly of the head cavity via at least two journal bearings which respectively receive journal pins associated with the ratchet mechanism. The novel sealing means comprises a pair of annular lip seals, each of which includes an opening that receives one of the journal pins. The annular lip seals bridge the gap between the exteriorly communicating journal bearings and journal pins, thereby facilitating the retention of lubricant and hindering the entry of foreign particles in the head cavity and ratchet mechanism housed therein.

  • Patent number: 4728608
    Abstract: A tetrazolium-based system for testing for the presence of organisms or cells in a specimen includes in one embodiment a mixture of a substrate and an indicator system, wherein the overall system is buffered to a pH above 8.0, and in a preferred embodiment at about a pH of 9.0 when mixed. The substrate solution and indicator solution are not mixed until shortly before use. The indicator solution is buffered at a pH of approximately 3.3, thereby enhancing the shelf life. The substrate may consist of glucose with at least one amino acid in a buffered solution formulated such that, by mixing equal parts with the indicator solution, a pH above 8, preferably 9.0 results.

  • Patent number: 4554248
    Abstract: A composition is used as a reagent in a method for measuring Antistreptolysin O (ASO) in a blood sample. The composition contains Streptolysin O (SO) at a pH outside the range of its hemolytic activity, e.g., outside the pH range of 5-9. At that pH the SO is reversibly inactivated while maintaining its hemolytic capacity. The composition is employed to measure ASO by mixing one or more samples of non-hemolyzed blood or serum with one or more known quantities of the composition with a known hemolytic capacity, incubating each mixture to allow reaction of any ASO in the sample with the SO, restoring the hemolytic activity of the SO by adjustment of pH to permit lysis and detecting the presence or absence of lysis in each sample.
