Touch-sensitive input screen having regional sensitivity and resolution properties

Abstract: A touch screen panel having varied region-specific combinations of resolution and touch sensitivity may also incorporate display functionality. For a first embodiment of the invention, the majority of the screen area exhibits low resolution, high touch force characteristics. A smaller area of the screen exhibits low touch force and high resolution properties. For a second embodiment of the invention, at least a portion of the peripheral regions (i.e., regions near the circumferential edge) of the screen are provided with regions of low touch force high resolution properties. These regions may be programmed to act as scroll bars, which would allow the user to change locations in a document of which only a portion is displayed on the screen. In the central regions of the screen, higher touch force and lower resolution provide palm rejection and coarse marking or movement capability with low bandwidth utilization. Either the varied screen properties may be incorporated into the screen during its manufacture, or the screen may be designed so that different resolution and touch sensitivity properties can be assigned to different regions of the screen to suit the user's needs.

Three-dimensional computer environment

Abstract: A method for displaying information about computer files to a user on a display in an environment simulating three dimensional space includes displaying a category of files as a container having a size related to its distance from a predefined portion of the display.

Technology Independent Large Signal Non Quasi-Static FET Models by Direct Construction from Automatically Characterized Device Data

Abstract: This paper describes a new, general and accurate, large signal GaAs FET model for nonlinear (e.g. harmonic balance) circuit simulation, its fast and unambiguous construction (model generation) by explicit calculations applied to the raw device data, and the adaptive, automated data acquisition system used to characterize the device. The model implementation in a harmonic balance simulator, the model generation procedure, and the automated data acquisition system form an efficient, practical, commercially available package. for state-of-the-art nonlinear circuit design.

Methods and system for using web browser to search large collections of documents

Abstract: A system for rapidly and easily searching large collections of documents using standard web browser programs as the user interface. The present invention parses a collection of text documents to identify symbols therein and builds a database file which identifies the file and line locations of each symbol identified. The database file is constructed to permit rapid searching for symbols to permit interactive use of the present invention as a search tool. A database client process interacts with the web browser via standard CGI techniques to convert browser commands and queries into appropriate server process requests. A server process receives such requests and manipulates the database files in response to the requests. Query results returned to the client process are then reformatted by the client process to return a document with hypertext links in place of search keys located in the database (e.g., an HTML page). The system of the present invention thereby provides for rapid searching of large collections of text documents which is not coupled to a specific toolset used to create any one of the documents and which uses a simple and well-known user interface, namely: web browsers.

USB virtual devices

Abstract: A management sub-system connects via a USB bus to a server or computer being managed. The management sub-system also couples to a management console, which has a number of conventional peripherals, including CD-ROM, floppy drive, hard disk, keyboard, mouse, and the like. These peripherals are emulated as USB peripherals coupled to the server by the management sub-system. The management sub-system includes a Composite USB function logic device that connects to the USB controller in the server. The Composite USB function logic device emulates the various peripherals available at the management console, and provides configuration data to the USB controller consistent with the emulation. Consequently, the server sends and receives data from these peripherals at the management console, as if the peripherals were locally connected by the USB bus to the server. The management sub-system monitors the operation of the server and publishes a web page that can be viewed by a web browser at the management console. In addition to viewing this status information, the management console can operate as a virtual terminal, capable of downloading files and programs from any of the emulated peripherals to the server, and of receiving input signals from the emulated input devices.
