Appl. No.:

09/421574

Inventors:

Donald W. Moses - Eagan MN

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 1700

US Classification:

700 94, 381 56, 380236, 380238

Abstract:

The foregoing problems are solved and a technical advance is achieved by a computer-implemented system for providing a digital watermark in an audio signal. In a preferred embodiment, a audio file, such as a. WAV file, representing an audio signal to be watermarked is preprocessed using an algorithm of the present invention herein referred to as the âPAWS algorithmâ to determine and log the location and number of opportunities that exist for inserting a watermark into the audio signal such that it will be masked by the audio signal. The user can adjust certain parameters of the PAWS algorithm before the audio file is processed. A/B/X testing between the original and watermarked files is also supported to allow the user to undo or re-encode the watermark, if desired.

International Classification:

H04B 704

US Classification:

375347

Abstract:

A frequency diversity digital wireless transmission system and method according to which a number of relatively narrow bands are established, each using multiple averaging interpolators. The serial data bits are divided by a predetermined pattern among the frequency bands providing frequency diversity. In response to one or more of the bands being lost to multipath fading or interference, the interpolated signals of the remaining bands are used.

US Classification:

343770, 343700 MS, 343795

Abstract:

Provided is an antenna system for operating in clear line of sight and obscured line of sight conditions. The antenna system includes multiple antenna elements arranged to provide both space and angle diversity characteristics. The elements are spaced apart so as to provide independence but may have overlapping radiation patterns. Each element includes a main radiation lobe and the elements are arranged so that the main radiation lobes are oriented at diverse angles.

US Classification:

340870130

Abstract:

The data telemetry system disclosed is a complete data communications systems suitable for use by utilities such as electric companies, gas companies and water companies which can be used for meter reading and load management at individual subscribers premises. Elements of the system can also be used as a power load carrier in a premise specific local area network (LAN). With the system is disclosed, all 10,000 subscribers per exchange can be serviced. It will be understood that data can be multiplexed between a central office location and remote subscribers for any suitable purpose with the data system as disclosed. A packet switching structure is disclosed having eight to thirty-two bytes in the data message. This packet is routed between the utility and remote subscriber with routing headers being added and deleted as required by the network modules. Each successive layer of the multiplexing and switching hierarchy submultiplies the aggregate 10,000 channel capacity into fewer channels.

International Classification:

H04K 110

US Classification:

375202

Abstract:

A communication system for simultaneously transmitting data and audio signals via a conventional audio communications channel using perceptual coding techniques Is disclosed. In a preferred embodiment, a first artificial neural network (NN) at an encoder monitors an audio channel to detect "opportunities" to insert the data signal such that the inserted signals are masked by the audio signal, as defined by the "perceptual entropy envelope" of the audio signal. Under the control of the first NN a data signal containing, for example, an ID or serial number, is encoded as one or more whitened direct sequence spread spectrum signals and/or a narrowband FSK data signal and transmitted at the time, frequency and level determined by the first NN such that the data signal is masked by the audio signal. The audio signal is combined with the spread spectrum and/or the FSK data signal(s) to form a composite signal, which is transmitted to one or more receiving locations via the audio channel. A decoder at each of the receiving locations comprises preprocessing circuitry, receiver sync circuitry and FSK decoder circuitry, as well as a second NN, which NN uses pattern and signature recognition techniques to perform block decoding, bit deinterleaving and acquisition confirm functions to recover the encoded ID or serial number.

International Classification:

G06F 1531

US Classification:

36472410

Abstract:

A method and system is provided for a digital audio system to reconstruct a digital audio signal using time domain interpolation and direct power digital-to-analog conversion. A signal processor performs the time domain interpolation on an original digital audio signal to allow for the proper recreation of the original audio signal and a direct power output digital-to-analog converter generates an analog power audio output signal from the interpolated digital audio signal that can directly drive a speaker to produce the sound waves represented by the audio output signal. The signal processor and direct power output digital-to-analog converter allow a digital audio system to more precisely reconstruct an analog power output audio signal from a digital audio signal such that there is no need for further amplification of the audio output signal and such that there will be no perceptible difference between the reconstructed digital signal and the original analog signal.

International Classification:

H03F 2100

US Classification:

341144

Abstract:

A direct power output digital to analog conversion of digital audio signals operates to directly convert digital audio signals into an analog power audio output signal capable of driving a speaker, such that there is no need for further amplification or modification of the audio output signal after the direct power output digital to analog conversion of the digital audio signals. The direct power output digital to analog conversion incorporates a digital-to-analog converter within the same feedback circuit as a current-to-voltage power amplifier by using a single resistive feedback network to supply the feedback signal from the output terminal of the current-to-voltage power amplifier to the summing junction of the same current-to-voltage power amplifier.
