Abstract: A first and second integrated circuit contain respectively a first and second portion of a parallel port, the first portion includes control, configuration, data and status registers and the second portion includes parallel port input and output terminals. A bus couples the first and second integrated circuits and transfers parallel port control and data information between the first and second integrated circuits. The bus includes a clock line providing a clock signal. The bus also includes a data out line that serially transfers output control and data bits from the first to the second integrated circuit, the data and control bits to be provided to the parallel port output terminals on the second integrated circuit. The bus also includes a data in line providing input data and control information from the terminals of the parallel port to the first integrated circuit.

Abstract: A first and a second local interrupt controller are disposed on a single integrated circuit. The first and second local interrupt controllers are coupled to controllably provide at least one interrupt request signal, respectively, to a first and second processor. An input/output (I/O) interrupt controller is also on the integrated circuit and coupled to receive an interrupt request from at least one input/output device. A communication circuit on the integrated circuit is coupled to the input/output interrupt controller and the first and second local interrupt controllers. The communication circuit provides for transfer of interrupt information between the first local interrupt controller, the second local interrupt controller and the input/output interrupt controller.

Abstract: An improved natural language parser uses a directed search template set to identify problematic word sequences, thus reducing processing time while increasing accuracy. The directed search template set is used to identify problematic input spans or portions of input spans. A problematic input span is one that contains at least one word or phrase that can be constructed in alternative ways. Problematic input spans can reduce the efficiency of a natural language parser and can result in the production of an inaccurate parse tree. Once a problematic span has been identified, the improved parser generates alternative parses for the problematic portion of the input span. This on-the-fly alternative parse generation permits the parser to consider the alternatives as early in the parse process as possible, thus reducing the overall time needed to parse a problematic input span.

Abstract: A method and apparatus for accessing information on a host computer 106 from a client computer 104 utilizing an intermediate server computer 108 that is connected to the client computer by a network. The host computer transmits a presentation space data stream representing a host screen to the server computer. The server computer creates an HTML document based on the information received from the host computer and transmits the HTML document to the client computer. The client computer creates a Web page based on the HTML document. The Web page includes fields and controls that implement the functionality of the host screens while presenting an improved user interface. A user can create HTML templates that substitute for the automatically created HTML documents for any one or more of the host screens.

Abstract: This invention relates to high power linear amplifiers. A high power linear amplifier is disclosed for communications such as CDMA communication systems. Linear amplifiers as used in communication systems exhibit a linear characteristic where the amplifiers output power increases relative to an input power. After a certain input level, known as a gain saturation point, the amplifier then exhibits non-linear characteristics; the output power increases relatively little with respect to power input. This non-linear region is also known as the saturation region or the gain compression region.

Abstract: A method and apparatus for accessing information on a host computer (104) from a client computer (112) that are connected by a network. The information accessed by the client computer (112) is represented as a plurality of fields in a presentation space data stream (208). The fields and corresponding attribute information in the presentation space data stream (208), as received from the host computer (104), are extracted and stored in field objects contained within a Display control (202). A set of events is provided by the Display control to an application program (204), the events providing information to allow the application program (204) to manage the interaction between an operator and the host computer (104). A set of properties and methods provide the application program (204) with the ability to traverse the field objects and thereby obtain the field information sent from the host computer.

Abstract: Construction materials such as 4-foot by 8-foot sheets of plywood, drywall, and similar materials have fiducial markings for quick visual reference of the user. Imprinted lines of equal spacings indicate to the user the location of wall studs at 16-inch or 24-inch spacings, and the sheet of material can also include oblique lines and one or more circles, for reference of the user in quickly determining the size of remnants. Similar markings may also be applied to roll-stored materials such as carpeting.

Abstract: The present invention discloses a method, apparatus, and article of manufacture for version migration and fallback of software components in a computer system. The invention creates alternate boot environments that preserve the state of all original software components on a system before performing a software upgrade. The invention virtually eliminates the risks of migrating to upgraded system because users can quickly fall back to a previous operating environment, without extended downtime during and after upgrades.

Abstract: A method for preserving the existence of a control during the lifetime of its container application is provided. A naming control is specified in an HTML document prior to specifying the target control. The naming control receives as a parameter a control identifier, which is passed to the class factory of the target control prior to creation of the target control. The class factory maintains a control list, with an entry for each control identifier corresponding to a currently active control. When a Web page is exited, the control is not deleted. Upon returning to the Web page and prior to creating a new control, the control list is checked to determine whether a control with a desired identifier is currently active. If so, a pointer to the corresponding control is returned, rather than create a new control.

Abstract: A hydrogen and natural gas fuel mixture for internal combustion engines is provided for vehicle engines such as those used in standard production engines for automobiles, trains and lawn mowers. The gaseous fuel for operating a vehicle combustion engines includes approximately 21 to 50% Hydrogen and the rest natural gas constituents such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Iso Pentane, N-Pentane, and Hexanes Plus. A fuel mixture of approximately 28 to 36 percent Hydrogen and a air fuel equivalence ratio of approximately 0.625 is an extreme lean burn condition that yields hydrocarbon emission levels of less than approximately 104 ppm(0.84 hm/hp hr.). Current internal combustion engines that are in mass production can take this alternative fuel without any substantial modifications to their systems. This alternative fuel is lean burning and emits emissions that are below current legal standards.
