Abstract: The builder's square aids in cutting sheet material, such as full sheets of plywood, and in particular reduces the time required for cutting. The square comprises a short leg and a long leg connected in an L-shape. The short leg is of greater height than the long leg so that it can bear against one edge of the sheet of plywood to be cut. There is a clamping member at the distal end of the long leg so that the square can be clamped to the plywood. The builder's square also provides improved accuracy and safety for the user.

Abstract: A method and apparatus for surveying a three dimensional sub-surface geological structure having seismic scatterers includes establishing an acquisition system (19) having at least two substantially vertical arrays of sensors (20) disposed within the geological structure. Each array (20) includes multiple directional sensing receivers 30 adapted to receive seismic energy (28, 97) produced from the seismic scatterers (24) in response to at least one seismic disturbance (27).

A recorder records the measurements of the received seismic energy for producing a complete vector field response of the seismic scatterers to the at least one seismic disturbance. Lastly, a processor processes the complete vector field to generate a three-dimensional image.

Abstract: An audio controller circuit to generate audible sounds for use on a computer system comprising a digital audio controller that generates digital audio signals reproducible by a digital audio device. The digital controller also operates in conjunction with a mixed-signal codec to generate analog audio signals reproducible by an analog audio device. The controller circuit is capable of delivering audio signals to a plurality of audio output connectors, each configured to accept a mating connector coupled to an external audio device. The audio controller circuit transmits audio signals to one output at a time. The circuit detects whether the external audio device coupled to an output connector is an analog or digital device and transmits the appropriate analog or digital audio signals to the output device.

Access to the legal information is provided to a client via the network.

Abstract: An air mattress includes a top sheet made of woven textile material laminated to an inner sheet of PVC and welded to bottom sheet made of PVC. Oval beams are welded to the inner and bottom sheets which are joined by lap seams. Support strips are provided for securing the lap seams at each corner.

Abstract: A computing system includes a memory bus, an input/output bus, a main memory, and an input/output adapter. The memory bus provides information transfer. The input/output bus also provides information transfer. For example the input/output bus is an input/output bus onto which is connected input/output devices. The main memory is connected to the memory bus. The main memory includes a page directory. The page directory stores translations. Each translation in the page directory includes a portion of an address for data transferred over the input/output bus, for example, the page address portion of I/O bus address. Each translation in the page directory also is indexed by a portion of an address for a memory location within the main memory, for example, the page address portion of the address for the memory location. The input/output adapter is connected to the memory bus and the input/output bus. The input/output adapter includes an input/output translation look-aside buffer.

Abstract: A computing system is presented which includes a memory, an input/output adapter and a processor. The processor includes a write back cache in which dirty data may be stored. When performing a coherent write from the input/output adapter to the memory, a block of data is written from the input/output adapter to a memory location within the memory. The block of data contains less data than a full cache line in the write back cache. The write back cache is searched to determine whether the write back cache contains data for the memory location. When the search determines that the write back cache contains data for the memory location a full cache line which contains the data for the memory location is purged.

Abstract: A wave reduction system for a water mattress having a plurality of buoyant chambers sealed on a separation sheet used to divide the mattress interior between an upper and lower water containing chambers. The separation sheet is connected by a welded seam to a top and a bottom sheet of the mattress, and has cut-out portions at corners of the mattress to relieve stress on the welded seam. Passages are located in the separation sheet for communicating with each chamber.

Abstract: A computing system includes a main memory and an input/output adapter. The input/output adapter accesses a translation map. The translation map maps input/output page numbers to memory address page numbers. Entries to the translation map are generated so that each entry includes an address of a data page in the main memory and transaction configuration information. The transaction configuration information is utilized by the input/output adapter during data transactions to and from the data page.

Abstract: A method for nondestructive examination of an object of type having localized permeability variations therein and varying surface conditions and grain structures comprises the steps of AC flux saturating a localized surface area of the object so as to magnetically saturate the surface area to quiet localized permeability variations therein and to set up a stabilized high level primary field on the surface substantially unalterable by the varying surface conditions and grain structures in the object and detecting eddy currents in the surface area. Coil structure and apparatus for implementing the method are also defined. Further, the method is disclosed as being implemented in part by the use of components of a pre-existing object evaluation device.

Abstract: Chemical preparation techniques involving co-precipitation of metals are used to provide micro-structural characteristics necessary in order to produce ZnO varistors and their precursors for high field applications. The varistors produced have homogeneous and/or uniform dopant distributions and a submicron average grain size with a narrow size distribution. Precursor powders are prepared via chemical precipitation techniques and varistors made by sintering uniaxially and/or isostatically pressed pellets.
