Abstract: Authentication of a signal, signalA, 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, signalB, where signalB contains an unknown signal that is unique to the source, and determining that signalA contains the same unknown signal that is contained in signalB.

Abstract: An arrangement including a receiver that receives a plurality of signals from different source that are modulated with a common carrier, where each signal of the signals experiences a transit delay and Doppler frequency shift before reaching the receiver. 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. The arrangement further includes means for processing a signal derived from the signals received by the receiver with signals provided by a supplicant module to reach a conclusion about the bona fide of the signals provided by the supplicant module.

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.

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.

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.

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.

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.

Abstract: An engine muffler and spark arrester includes an oval shaped outer tube extending along an axis and having an inlet end and an outlet end. A plurality of substantially identical nested oval shaped disks are disposed coaxially adjacent the outlet end. Each of the disks has an oval shaped centrally located aperture. An inner tube is disposed coaxially within the outer tube. The inner tube has a circular inlet end and an oval-shaped outlet end. An oval end cap is disposed adjacent the disks. A sound absorbent material can be disposed in a cavity defined between the inner tube and the outer tube. An oval-shaped inlet cap is secured to the inlet end of the outer tube with the inlet cap having a circular centrally located aperture extending therethrough. An oval-shaped outlet cap is secured to the outlet end of the outer tube. The outlet cap has an oval-shaped centrally located aperture extending therethrough.
