Abstract: A power conditioning circuit for conditioning power supplied by a power source at a nominal frequency over conductors in a polyphase system includes first and second phase conductors. First and second inductors are connected in series between the first and second phase conductors and first and second phase output lines, wherein all of the power supplied by the power source to the first and second phase output lines flows through the first and second inductors. An inductance of each of the first and second inductors increases when power at frequencies greater than the nominal frequency flows through the first and second phase conductors, thereby blocking power at frequencies greater than the nominal frequency from reaching the first and second phase output lines.

Abstract: A method and apparatus for distributing the data error correction and compression processing load between a modem (DCE) and a host data terminal equipment (DTE) enables modem implementation with minimal cost, power dissipation, and size. The DTE has a CPU and an associated memory. The memory contains a data transmission program for execution by the CPU to produce output data for transmitting, and at least a data compression algorithm and a data error checking algorithm for execution by the CPU under control of the data transmission program to asynchronously deliver data according to the data transmission program to a modem for synchronous transmission. The modem included in the DCE asynchronously received the data from the DTE and synchronously transmits it as output data. Due to the distribution of the data processing algorithms into the memory of the DTE, the DCE can be operated simultaneously in communication and control modes.

Abstract: Three technologies realize monocrystalline three-dimensional (3-D) integrated circuits: (1) silicon sputter epitaxy permitting fast growth at low temperature; (2) real-time pattern generation using a pixel-by-pixel programmable device to create a patterned beam of energetic radiation; and (3) flash diffusion focuses through a projector barrel the patterned beam on a silicon sample, causing localized dopant diffusion from a heavily doped region at the surface into the underlying region. Removing the heavily doped layer leaves a 2-D doping pattern. Creating additional 2-D patterns on top of it through process repetition produces a buried 3-D doping pattern. One configuration places projector barrel and sample in fixed positions inside the sputtering chamber and a ring of targets around the barrel facing the sample with targets of a given kind symmetrically positioned in the ring. Cobalt can be substituted for the doping layer and can be driven in creating silicide conductive patterns.

Abstract: Three technologies are brought together to realize monocrystalline three-dimensional (3-D) integrated circuits. They are silicon sputter epitaxy, which permits fast growth at low temperatures, and can be switched instantaneously to a material-removal mode by a bias change; (2) real-time pattern generation, which uses a Digital Micromirror Device, or one of similar properties, to create a beam of energetic radiation that is patterned on a pixel-by-pixel basis; and (3) flash diffusion, which focuses the patterned beam on a silicon surface, causing localized heating, and localized dopant diffusion from a heavily doped region at the surface into the underlying region. By removing the heavily doped layer, one is left with a 2-D doping pattern, and by creating additional 2-D patterns on top of it through process repetition, one arrives at a buried 3-D doping pattern.

The method stores a plurality of executable functions, scheduling functions, and data types. A data flow diagram is assembled in response to the user input utilizing icons which correspond to the respective executable functions, scheduling functions, and data types which are interconnected by arcs on the screen. A panel, representative of an instrument fron panel having input and output formats is likewise assembled for the data flow diagram. An executable program is generated in response to the data flow diagram and the panel utilizing the executable functions, scheduling functions, and data types stored in the memory. Furthermore, the executable functions may include user defined functions that have been generated using the method for programming. In this manner, a hierarchy of procedures is implemented, each represented by a data flow diagram.

Abstract: A computer system is programmed by a user to perform dataflow computations by constructing a dataflow block diagram that utilizes function icons. At least a subset of the function icons are polymorphic with respect to data type and with respect to data aggregation. A polymorphic function icon is executed by performing a single mathematical operation when its inputs are scalars, while the same icon is executed on an element when its inputs are arrays or a scalar and an array. With cluster inputs, the polymorphic function icon is executed on a component by component basis. Output types of polymorphic function icons are determined by their input types prior to executing the diagram. The system automatically constructs a connection diagram consisting of an icon with connection points that are labelled with the names of associated front panel controls and indicators. A front panel control can be hidden to make the associated control value a constant.

Abstract: A graphical system for executing a process or for programming a computer to execute the process is based on graphical programming techniques. Techniques include composing a graphical front panel of an instrument which provides a means for the user to provide input and monitor outputs of the process, composing a data flow diagram using graphical representations of data flow structures, and in response to the data flow diagram and the panel diagram, composing a sequence of execution instructions to carry out the diagrammed process in response to inputs provided by the panel to supply outputs displayed by the panel. The system is based on libraries of executable functions and variable types having corrresponding icons. The user selects icons which have corresponding entries in the libraries to assemble the diagrams.

Abstract: A data compression system for increasing the speed of data transmission system over a communication channel with a predefined data transmission rate. The system has two data compression units--one on each end of the channel, coupled to first and second data processing systems. Input data from either data processing system is encoded using a selected one of a plurality of encoding tables, each of which defines a method of encoding data using codes whose length varies inversely with the frequency of units of data in a predefined set of data. Whenever an analysis of the encoded data indicates that the data is not being efficiently compressed, the system invokes a table changer for selecting from among the encoding tables the one which minimizes the bit length of the encoded data for a preselected sample of the input data. If a new table is selected, a table change code which corresponds to the selected table is added to the encoded data.
