Appl. No.:

09/764772

Assignee:

Interland, Inc. - Atlanta GA

International Classification:

G06F017/00

US Classification:

7155011

Abstract:

The present invention comprises a novel system for authoring and publishing hypermedia works. The present invention includes a scrollable contents map window in which a graphical representation of a hypermedia work is displayed. The contents map window contains graphical lexia symbols representing the lexia of the hypermedia work, empty space, and other graphical and text elements. Links between lexia are not ordinarily displayed. Selecting a lexia symbol causes the corresponding lexia to be displayed in a lexia display window. The lexia symbols representing lexia may be arranged in the window in any configuration. Freely movable text labels and other graphical elements may be placed anywhere in the contents map window. Additional special purpose graphical elements may be placed in the contents map window to create relationships among lexia. In one embodiment, a number of different modes of the contents map window can be displayed.

US Classification:

326 38, 326 39, 326 41

Abstract:

A method and system is provided for Network-on-Chip (NoC) and other integrated circuit architectures. A configurable fabric circuit (CFC) is interfaced with one or more core circuits and the CFC is responsive to an input signal and capable of reconfiguring the logic circuit in the CFC in accordance with an operational mode determined based on the received input signal to facilitate a core circuit interfaced therewith to carry out an operation consistent with the operational mode.

International Classification:

G01S 19/21
G01S 19/20

US Classification:

34235759, 34235758

Abstract:

Authentication of a signal, signal, that is provided as having been received from a source at a first global location by comparing it to a signal that is received from the source at a second global location, signal, where signalcontains an unknown signal that is unique to the source, and determining, that signalcontains the same unknown signal that is contained in signal.

G01S 19/32

US Classification:

3423574, 34235746, 34235772

Abstract:

A receiver that receives a plurality of signals that are modulated with a common carrier, where each signal of said signals originates at a different source and experiences a transit delay and Doppler frequency shift before reaching the receiver, and where the transit delay and Doppler frequency shift are related to position and movement of each of the respective sources. The receiver includes means, such as a directional antenna, to ensure that the received signals are bona fide, or at least not subject to the same bogus signal or signals to which a second receiver may be subjected.

International Classification:

H04B 1/00

US Classification:

375147

Abstract:

A module for receiving a plurality of signals that are modulated with a common carrier, where each of the signals includes information that enables a determination of a distance from said receiver to a source that transmits the signal, and outputs to outside the module a digital representation of a downshifted replica of the received signals or, alternatively, outputs a stored and delayed version of the downshifted replica of the received signals together with information about the delay.

US Classification:

715501100

Abstract:

The present invention comprises a novel system for authoring and publishing hypermedia works. The present invention includes a scrollable contents map window in which a graphical representation of a hypermedia work is displayed. The contents map window contains graphical lexia symbols representing the lexia of the hypermedia work, empty space, and other graphical and text elements. Links between lexia are not ordinarily displayed. Selecting a lexia symbol causes the corresponding lexia to be displayed in a lexia display window. The lexia symbols representing lexia may be arranged in the window in any configuration. Freely movable text labels and other graphical elements may be placed anywhere in the contents map window. Additional special purpose graphical elements may be placed in the contents map window to create relationships among lexia. In one embodiment, a number of different modes of the contents map window can be displayed. One mode is a caricature mode. In caricature mode, lexia are represented by novel, information rich, dynamic lexia symbols with enhanced mnemonic features and visual cues called “caricatures”. The mnemonic features and visual cues of a caricature, together with its position with respect to other elements in the contents map, provide means for uniquely visually identifying the underlying lexia. One embodiment of the invention includes a search function that allows an author or a reader to search some or all of the lexia of a work for specific words, phrases, or other items such as links. Lexia symbols of each lexia containing the searched for text are highlighted in the contents map window.

US Classification:

713323000

Abstract:

An autonomous on-chip power management system for managing power consumption of an functional block in an integrated circuit includes power management circuitry configured to monitor signals relevant to the function of the functional block for detecting a predetermined condition associated with the signals, and, in response to the detection of the predetermined condition, to set the functional block to a power saving mode, and, in response to the detection of a predetermined reactivating condition associated with the signals, to set the functional block to a normal operational mode.
