International Classification:

G01R 29/12
G01R 27/26

US Classification:

324457, 324658

Abstract:

A sensor for sensing an electric field includes a movable sensor probe including one or more pair, typically three pair, of electrically conductive electrodes, and may include one or more pair of selectively switchable auxiliary electrodes. The probe is movable and may be mounted on a vehicle or trailer. A processor may process electric field signals from the probe for providing a human perceivable indication of the electric field. The processor may perform a Fast Fourier Transform of the electric field signals to produce an indication of the magnitude of the electric field, and may perform unweighted and/or weighted averaging in relation to processing electric field data, setting a comparison threshold, providing a human perceivable indication, or a combination of the foregoing. A speed at which the sensor probe is moving may be utilized in processing the data.

G01R 23/16

US Classification:

324686, 324457, 702 77

Abstract:

A method for sensing an electric field includes processing digitized electric field signals, e. g. , from an electric field sensing probe. The processing may include performing a Fast Fourier Transform of the digitized electric field signals to provide an indication of the magnitude of the electric field, and may include processing the digitized electric field signals at a rate that is related to the speed at which a movable sensing probe is moving. The method may include performing unweighted and/or weighted averaging in relation to processing electric field data, setting a comparison threshold, providing a human perceivable indication, or a combination of the foregoing.

International Classification:

G06K 9/00
H04N 7/167
H04L 9/00

US Classification:

382100, 380201, 705 57, 713176

Abstract:

A method and apparatus for providing an improved workflow for digital watermarking during a production process. The invention provides a content tracking authority facility that forms a centralized location for storing and distributing watermarks and locations within a payload to place the watermarks. All post-production facilities that are involved in processing a particular payload (e. g. , any content that can be watermarked, including video content) connect to the content tracking authority facility to receive watermarks for the content they are processing as well as locations within the content to use to place the watermark.

International Classification:

G06K 9/00

US Classification:

382100, 382288, 380205

Abstract:

A method and apparatus for inserting a low frequency watermark into a compressed data stream carrying compressed content is disclosed. A portion of the compressed data stream is decoded to generate decoded content. The decoded content is analyzed to generate watermark insertion information. The compressed content is embedded with a low frequency watermark using the watermark insertion information.
