    摘要: An event visualization system. The system uses a digital video capture array. The array is synchronized into a composited video feed file. The composited video feed file has a number of unit perspective video files. Each unit perspective video file has a coordinate location, a unit frame height, and a unit frame width. The unit perspective video files can be played simultaneously for individual display in a digital event player. The digital event player is operated on a client.

    摘要: An apparatus and method for generating a two-dimensional back-projected image of a slice of an object. In accordance with the invention there is provided a carrier means having a plurality of substantially parallel elongated projections thereon, each projection having an optical characteristic (transmissivity or reflectivity) representing the density characteristic of said slice of the object as measured at a particular relative rotational angle. Means are provided for imaging successive sinusoidal patterns on the carrier means, the successive sinusoidal patterns being imaged at a predetermined rate. Photodetector means are responsive to the imaged sinusoidal patterns. Finally, a display or recording means, synchronized at the predetermined rate, is responsive to the output of the photodetector for displaying the back-projected image. In a preferred embodiment of the invention the carrier means is a cylindrical film having projections thereon with transmissivities that represent the density characteristic of the slice of the object under consideration. In this embodiment, means are provided for uniformly illuminating the projections and optical mask means are provided in spaced relation to the cylindrical film and operative to image portions of the projections on the cylindrical film. Means are provided for rotating the cylindrical film on its axis so that the mask means continuously images different groups of projections on the film. Means are also provided for effecting relative angular motion between the mask means and the axis of the cylindrical film, whereby the mask means continuously images varying portions of the cylindrical film, the variation being along the axial direction thereof. In this embodiment the display means is synchronized with the rotational rate of the cylindrical film and with the effective angular displacement rate between the mask means and the axis of the cylindrical film.

    摘要: A method of drilling a gas or oil well consists of use of a water-based drilling fluids containing high molecular weight crosslinked polyacrylic acid as viscosifying agent. The drilling fluid may further contain a lubricant, weighting agent and/or a wetting agent as well as a synthetic silicate or smectite clay. The aqueous based drilling fluid exhibits a coefficient of friction which is substantially close to the coefficient of friction of oil based drilling muds. The drilling fluid exhibits stability at well temperatures in excess of 150° C.

    摘要: For baby strollers, particularly umbrella strollers, a device to prevent tipping comprising a pair of rearward extension bars. Each bar is adapted to extend rearwardly over or nearly over one of the rear wheels of the stroller. Each curves downwards so as to clear the wheel over or near which it extends and then curves to present a distal end section at least approximately parallel to the surface on which the stroller sits. Each bar is provided with a clamp by which it may be attached to the stroller. The clamp is adjustable to optimize tip prevention and loosenable so that the extension may be folded transversely for storage or transport.
