Extensible resource messaging between user applications and network elements in a communication network
InactiveUS20060075042A1Easily use new network resourceAvoid resourcesMultiple digital computer combinationsTransmissionXML schemaMessage passing
Extensible resource messaging in a communication network is provided through creation of a flexible, extensible, and secure messaging environment. A client-server architecture may be implemented in which user applications employ messaging clients to send resource requests for network information, allocation and other operations and receive resource responses, and in which network elements, through resource agents, may use messaging servers to accept resource requests and return resource responses. Resource agents in different network domains may interact through the messaging environment and work together to fulfill resource requests. An XML-based messaging mechanism may be built with a defined message format that can provide flexible message contexts. Network resource semantics may be specified using XML schemas so that network resources are expressed as resource-specific XML elements and network updates can be implemented by updating the XML resource schemas. Secure enhancements may be realized by secure transport, message verification and other means.

Classification of humans into multiple age categories from digital images
The present invention includes a method and system for automatically extracting the multi-class age category information of a person from digital images. The system detects the face of the person(s) in an image, extracts features from the face(s), and then classifies into one of the multiple age categories. Using appearance information from the entire face gives better results as compared to currently known techniques. Moreover, the described technique can be used to extract age category information in more robust manner than currently known methods, in environments with a high degree of variability in illumination, pose and presence of occlusion. Besides use as an automated data collection system wherein given the necessary facial information as the data, the age category of the person is determined automatically, the method could also be used for targeting certain age-groups in advertisements, surveillance, human computer interaction, security enhancements and immersive computer games.

Methods for road safety enhancement using mobile communication device
InactiveUS20130082874A1Sufficiently accurateQuick responseRegistering/indicating working of vehiclesDetection of traffic movementKinematic couplingSimulation
Methods for road safety enhancement use mobile communication device (MCD) onboard vehicle to share traveling data through inter-vehicle communication broadcasting, perform road hazard warning, enhance road navigation, and provide autonomous road assistance. The methods have a variety of vehicle status data, such as moving data, steering data, or indicator data, obtained through GPS or image capturing and recognition of instrument cluster of vehicle. The image capturing and recognition allows to get speed data from indication of speedometer, indication of left or right turn signal, steering action data corresponding to steering wheel rotation, and light-on indication of system status indicators. To facilitate that, the MCD may be placed in front of steering wheel, and, if applicable, also in coupling with movement of steering wheel. The MCD may perform relative positioning map-matching lane correlation and GPS-update-interval speed positioning to improve data quality regarding vehicle moving status.

Tamper-resistant authentication techniques for identification documents
The present invention provides techniques that are helpful in resolving the authentication of an identification document or banknote. The document or banknote includes a security enhancer. The enhancer can be a graphic or artwork design, or can be realized with line art. In the case of an identification document, the spatial characteristics of the security enhancer are preferably altered in accordance with information contained in the identification document. For example, if the ID document includes a photograph, a hashing algorithm will reduce the photograph to a number. The number is used to set a repeated spacing distance of elements in the security enhancer. The repeated spacing yields an identifiable frequency response that is related to the identification document photograph.

Electromagnetic safety enhancement circuit for universal serial bus systems
InactiveUS6101076ACircuit-breaking switches for excess currentsEmergency protective arrangement detailsControl signalElectromagnetic interference
An electromagnetic safety (EMS) enhancement circuit is provided for a USB (Universal Serial Bus) system, which can simulate an unplugging and replugging action so as to ensure continuous operation of the USB device after being disconnected from the USB interface due to electromagnetic interferences. The EMS enhancement circuit utilizes an EMS detection unit to detect the EMS condition of the data communication between the USB device and the USB interface; if abnormal, the EMS detection unit will output an overflow signal to a resume-control unit. The resume-control unit can output a pull-up control signal to a voltage pull-up circuit so as to control the voltage pull-up circuit in such a manner that, when the USB device is disconnected from the USB interface, the voltage pull-up circuit is first inhibited from outputting a voltage signal to one data line of the USB interface to thereby simulate an unplugging action and, after a preset time, be enabled again to output the voltage signal to thereby simulate a replugging action. The simulated unplugging and replugging action can then automatically reconnect the USB device to the USB interface for continuous operation of the USB device.

Aspects dynamically set enterprise-level security rules by assessing risk factors associated with a user. Risk values representing likelihoods of loss of enterprise secure data are determined for different attributes of a user, and added together to generate a user risk factor. If the risk factor does not meet one or more off-site access threshold value(s), additional security enhancements applicable to the user and not enabled within currently applied security are iteratively selected and used to revise the security settings, and the risk factor is revised by a risk abrogation value of each of the selected security enhancements, until either the revised risk factor meets the off-site access threshold value(s) (wherein access is granted to the secure data from the off-site location pursuant to the revised security settings), or until no additional applicable security enhancements are available (wherein user access to the secure data from the off-site location is denied).
