Technical Examples
- The present invention relates to a method of setting up a call matching a predetermined set of requested services and/or characteristics over a network, optionally a network that is composite and multi-component. The method is characterized in that it consists in subdividing said network into a plurality of domains, with a negotiator unit being associated with each domain, in sending to at least one negotiator unit a call setup request together with a set of parameters defining the services and/or characteristics associated with the call to be set up, and, where appropriate, in setting up the call after determining the appropriate available resources in the various domains concerned and selecting resources providing the best possible match with said set of services and/or characteristics.
- Application services gateways that execute electronic application programs/services allows the application programs/services to be managed and administered out of a network rather than locally. The application services gateways are elements in a services delivery system that execute application programs/services that control or otherwise interact with systems and devices of a home or business such as a heating and cooling system or a security system. The application services gateways have a LAN connection to a communication gateway that in turn communicates over a WAN to a remote services gateway. The remote services gateway channels data from a remote service platform to provide application programs/services and management services over the WAN to the communications gateway where it is then channeled to the application services gateways. The installation and management of the application programs/services residing and/or being executed at the local site on the application services gateways relieves the consumer of such responsibilities.
- A method of and an apparatus for enhancing digital image quality. Input color data are transformed to obtain brightness data and chrominance data. The transformed brightness data is compared with predetermined brightness levels X1 and X2 on a pixel by pixel basis and the brightness data of each concerned pixel is reset or output without change according to the comparison. The comparison identifies the concerned pixel as belonging to one of a dark area and a light area requiring contrast enhancement and the brightness level of the concerned pixel is adjusted to provide the enhanced contrast. The obtained chrominance data and the reset brightness data are inversely transformed into corresponding color data. The predetermined brightness levels X1 and X2 are adaptively recomputed after a last pixel in a concerned line is considered for contrast enhancement.
- An electronic services modeling tool for composite e-services and functionality, where a composite e-service is an e-service defined by composing other basic or composite e-services. Implementation of an e-service for composing e-services into a composite e-service. Characteristics of composite e-services and of their differences with respect to traditional workflow-like composition. Definition of a composition model suitable for e-services. Description of a prototype implementation, showing an approach that can be reused for implementing composition on top of any E-Services Platform. Providing composition functionality as an e-service, to be used not only by the owner of the ESP, but also by any designer-user. A specific type of e-service, meta-service, called Composition E-Service, allows the definition, execution, management, and monitoring of composite e-services. A language used for specifying the composition. Architecture and implementation of the CES to deliver the service on top of an ESP.
- In an image forming device management system and method of the present invention, a data communication device is connected to one or a plurality of image forming devices and a central control system is connected to the data communication device via a public switched telephone network and provides a remote maintenance of the one or the plurality of image forming devices through the telephone network and the data communication device. A communication request signal is transmitted from the data communication device to the image forming device concerned. When the request signal is received by the image forming device concerned, a supplying of a power from a main power source to the image forming device concerned is automatically turned on. The supplying of the power from the main power source to the image forming device concerned is automatically turned off after a communication between the data communication device and the image forming device concerned ends.
