  • Publication number: 20070036972
    Abstract: Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.

  • Publication number: 20070006206
    Abstract: When a user interface of a parent software application is modified such that user interface components of an add-in application are not compatible with the parent application user interface, user interface components associated with functionalities of the add-in application are added to the modified parent application user interface. A prior user interface of the parent application to which the add-in application user interface components are added is run in a background of the parent application and is not visible to users. User interface components in the parent application user interface are linked to corresponding add-in application user interface components in the prior user interface. Selection of a user interface component from the present user interface that is associated with an add-in application functionality causes selection of a corresponding user interface component in the background user interface, and the associated add-in functionality is executed.

  • Publication number: 20060199931
    Abstract: A fiber is obtainable from or comprises an ethylene/?-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481?1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers.

  • Publication number: 20060002474
    Abstract: A novel method, system, and apparatus for efficient multi-block motion estimation in a digital signal compression and coding scheme. This invention selects only a few representative block sizes for motion estimation when certain favourable conditions occur, rather than using all available block sizes. This invention produces significantly reduced computational costs with virtually no sacrifice in visual quality and in bit-rate.

  • Patent number: 5070752
    Abstract: A driving mechanism for a scroll sawing machine, which comprises a motor set in parallel with two suspension arms which have a scroll saw blade retained therebetween, and sector-shaped counter weight mounted on the shaft of such a motor and coupled with an universal link which has an opposite end secured to the suspension arms. The rotation of the motor drive the universal link to carry the suspension arms and the scroll saw blade to make a sawing motion for cutting something. Because the motor is set in parallel with the suspension arms, the saw bench is permitted to incline leftward and rightward during sawing operation.

  • Patent number: 5022157
    Abstract: A transmission mechanism for a scroll sawing machine is disclosed. An upper counter weight and a horizontal counter weight are secured to the lower end of a rocker arm, which has its top end secured to the scroll saw blade upper driving arm, and carried to move by the transmission shaft of a motor. The rotation of the transmission shaft of the motor drives the upper counter weight to rotate so as to eliminate any possible vertical shock waves, and simultaneously drives the rocker arm to move up and down so as to eliminate any possible horizontal shock waves.
