Abstract:
A laptop computer carrying case (10) transforms into a desktop (Fig. 1) for use of a laptop (26) or similar electronic device having a keyboard (28) and a hingeably openable display (30). The laptop key board (28) is held by bands (32, 34) in the bottom section (12) of the case and the display is held in the top section (14) of the case. Hinge structures (40, 50, 140, 150) are provided on the left and right sidewalls of the bottom section of the case. When the hinge structures (40, 50, 140, 150) are pivotally angularly separated, the bottom section (12) containing the keyboard (28) will be substantially horizontal enabling use of the laptop in a standing or mobile position (Fig. 1). When the laptop is not being used, the case may be closed and the hinge structures (40, 50, 140, 150) closed with the laptop being carried by the strap over the shoulder (Fig.2). The hinge structure is provided with structure (46, 48, 49, 148, 149) for limiting the amount by which the arms of the hinge may be pivotally angularly separated thereby providing stability to the laptop case in the desk top position. Detent means (70, 170) is provided to hold the arms (42, 44, 142, 144) of the hinge structure in aligned position when the case is being used to carry the laptop (Fig. 2).

Abstract:
Apparatus and methods for providing a pre-rasterized print job for variable data printing are disclosed. In one embodiment, a set of printer characteristics may be determined and then transferred to a typesetting system. The typesetting system may then pre-rasterize objects of the print job based in part on the received printer characteristics. A pre-rasterized print job, including the pre-rasterized objects and print layout instructions may then be generated, such as in the form of a PostScript file, which may then be transferred to a raster image processor (RIP) for generation of printed output. In another embodiment, a printer characterization file may be used for execution on a printing system to determine the set of printer characteristics, that may include native resolution, rotation angle, compression data and/or other data or information characterizing the printing system.
Abstract:
Discloses methods to perform magnetic testing of tensioning elements in a pre-stressed concrete cylinder, such as a pipe or water reservoir and testing apparatus. The apparatus includes magnetic flux production means and detector means disposed proximal to a surface of the cylinder in a plane in common with the magnetic flux production means that is orthogonal to an axis of the cylinder. The apparatus operates over a range of low frequency signals, for example, between 20 and 300 hertz or a pulse. Output of the inspection apparatus includes a signal and distance plot showing the results of testing a cylinder at one or more frequencies. In accordance with another method of analysis, a characteristic of the phase of the output over distance is plotted, including the phase or representations of the in-phase or quadrature components of the received signal in relation to the driving signal.
