International Classification:

G06K 900

US Classification:

382100, 713176, 348463

Abstract:

A data hiding system and method for providing a method of embedding multiple layers of hidden data into multimedia data. First, a media unit of the multimedia data is evaluated to determine an appropriate embedding procedure. Next during a first embedding pass, a ruling layer of primary hidden data is embedded into the media unit. In another embedding pass, a governing layer of secondary hidden data is embedded on top of the ruling layer. The secondary hidden data provides control information for controlling the primary hidden data and the host data. Control information such as error correction data, synchronization data, decoding data, and authentication data is embedded in the governing layer. Embedding schemes such as base domain and spectrum domain embedding are employed.

International Classification:

G06K 900

US Classification:

382100, 713176, 713179

Abstract:

A method and apparatus of hiding identification data in visual media. When image or video data is received, frequency masking is performed to divide the image or video data into blocks of smooth regions and blocks of non-smooth regions and to obtain preliminary just-noticeable-difference. Edge detection is performed to divide the non-smooth region of the image or video data into texture blocks and edge blocks. Then blocks of regions that are substantially proximate to blocks of smooth regions of the image or video data are determined. The image or video data is then adjusted by applying different strength of watermark in association with the type of each block.

US Classification:

370229, 370241, 7042701

Abstract:

A method for dynamically allocating network resources while transferring multimedia at variable bit-rates in a network extracts first content features from the multimedia to determine renegotiation points and observation periods. Second content features and traffic features are extracted from the multimedia bit stream during the observation periods. The second content features and the traffic features are combined in a neural network to predict the network resources to be allocated at the renegotiation points.

US Classification:

Abstract:

The digital air pressure gauge includes an error correction lookup table database stored within a memory device within the gauge. The database includes reference air pressure values and associated measured air pressure values, where the reference air pressure values and associated measured air pressure values are determined at identical discrete time intervals as pressurized air is input into the gauge. A transducer generates an electrical signal representative of air pressure within a device such as a pneumatic tire. A microprocessor compares the electrical signal with measured air pressure values within the database and determines a closest measured air pressure value. The microprocessor then determines the associated reference air pressure value of the closest measured air pressure value. The reference air pressure value is then displayed as the accurate pressure of the pressurized air within the device. The gauge may be disposed within a tire valve cap with an RF transmitter.

Inventors:

Min Wu - San Jose CA, US

International Classification:

E01C 23/00
B60C 23/02

US Classification:

73146

Abstract:

The pressure gauge is designed for operative engagement with a gas pressurized system such as a pneumatic tire. It includes a housing having a pressurized gas inlet orifice and a cylindrical bore formed within the housing. A pressure reactive piston is slidably engaged within the cylindrical bore, and a resistance means is disposed within the cylinder to provide a resistive force to the movement of the piston. A calibration rod is disposed proximate the piston, whereby movement of the piston will cause movement of the rod. A pressure indicator bar, which is threadably engaged to the rod, provides an indication of the pressure level of the gas. The calibration rod has a user accessible end, and rotation of the rod causes a calibration adjustment of the pressure indicator bar due to the threaded engagement of the rod with the pressure indicator bar.

Inventors:

Min Wu - San Jose CA, US

International Classification:

G01M 17/02

US Classification:

73146, 340442

Abstract:

A multiple-function valve cap is disclosed for mounting on a valve stem of a tire for indicating a safe pressure condition or a low pressure warning. The multiple-function valve cap includes a pressure indicator assembly having a piston including a safe pressure indicator, and an internal bore. A warning indicator is seated within the internal bore of the piston. A biasing spring is fitted between the low pressure warning indicator and the safe pressure indicator, and acts to urge them apart, such that the warning indicator is displayed when low pressure is applied to the piston. When a safe level of air pressure is applied to the piston, the piston is moved against the force of the biasing spring to surround the warning indicator, and the safe pressure indicator is displayed.

International Classification:

US Classification:

726 32, 382116, 713186

Abstract:

To identify participants in collusion directed to altering a digital fingerprint embedded in multimedia content, an ECC based fingerprinting technique establishes a code symbol for each of a plurality of segments of digital data forming the multimedia content. The code symbols are concatenated to form a fingerprint signal, which is subdivided into a plurality of subsegments for each segment in the digital data. The subsegments are permuted and embedded into the digital data. When a suspicious copy of the multimedia content is discovered, the permuted fingerprint signal is extracted from the content and inversely permuted to form a test fingerprint. The identity of one of the colluders is determined by correlation with characteristics of the codeword originally assigned to the user. The determination of identity may be enhanced by the addition of group data embedded as an additional fingerprint in the digital data. Joint consideration of coding and embedding provide benefits over previous fingerprinting techniques.
