A directed graph of data includes nodes 10, properties 22 attached to nodes and resources 34. The nodes 10, properties 22 and resources 34 are classified as indexable or non indexable. At least one property 30 links a pair of nodes, one node being a parent and one being a child. An indexing algorithm indexes each indexable property pointing to a resource as related to any respective indexable nodes linked to the node to which the indexable property is attached through a chain of indexable links from child to parent through intermediate nodes, all of which are non-indexable.

A method of providing data from a data repository to a client application, comprises receiving an initial query from a client application and obtaining a first set of results from the data repository to the initial query. If the total number of results of the first set is greater than a predetermined number for provision as a single page, a second set of results is stored in memory and a page of results is provided. An indication of the total number of results to the initial query is provided as well as an indication of the position of the results of the page within the set of results, and an indication of the range of the results for which subsequent queries will return results consistent with the initial query. This provides a results paging model to allow a client application to page through a large set of query results, with transparent indication of the consistency between the pages of results.

A digital repository 20 includes data items. A user can add additional functionality or program routines to data item by including as a data item a data processing identifier pointing to at least one data processing routine. Such routines are accessed by a client 22 by sending from a client to the digital repository 20 a request to access a data item, wherein the repository provides an interface description document 32 from the digital repository 20 to the client 22 as the response to the request. The client 22 can then transmit a data processing request from the client to a service 26 identified by the data processing identifier of the interface description document 32, the data processing request including the identifier from the interface description document.

A database security structure that may be used for semistructured databases assigns each node 4 of a database to a collection. For each collection, create rights, retrieve rights, associate rights and dissassociate rights are provided to one or more users, the rights being assigned in common for all nodes of the collection. Users can only carry out the task if they have the appropriate rights. In this way, a flexible database security structure is provided that can deliver appropriate security for different elements of a semistructured database.

The present subject matter is directed to electronic circuitry and associated hardware configured to electronically control directional signals, i.e., neutral, forward and reverse signals, to the transmission of a watercraft. The circuitry provides for electronic control of the throttle position of the watercraft engine and electronic override of the transmission shifting circuitry to allow throttling up (i.e., revving) of the engine without placing the transmission into gear. In an alternative embodiment, directional control is effected by operation of a lever mechanism and override functionality is effected by manual disengagement of a drive mechanism for the directional control while maintaining operation of the electronic throttle control.

A computer processor and associated computer memory which has in the memory a number of existing content processing operations (CPOs) which include associated description of the type of content they can process, and which has installed, and runable on it, a content processing operation protocol software which is capable of identifying the input requirements of input pins of the CPOs, and which can enable the characteristics of outputs of the CPOs to be identified; and which processor also has installed and runable on it CPO binding software which is adapted to reserve the operation of one CPO and provide its output to another CPO, and which has the protocol necessary to promise the services of one CPO to another CPO, the CPO binding software being able to interpret and use the characteristics of the CPOs expressed in the CPO protocol to determine that it is appropriate to link the one CPO with the other CPO to produce a desired overall function.
摘要:
A antenna aperture having electromagnetic radiating elements embedded in structural wall portions of a honeycomb-like core. Independent wall sections each having a plurality electromagnetic radiating elements are formed into the honeycomb-like core. Feed portions of each radiating element form teeth that are copper plated before being assembled onto a back skin panel. Each of the teeth are then generally machined flush with a surface of the back skin to present electrical contact pads which enable electrical coupling to each of the radiating elements by an external antenna electronics board.

The present invention comprises systems and methods for preventing collisions between aircraft and ground vehicles. In one embodiment, a system includes a proximity detection unit and a transducer proximate to a selected structural portion of an aircraft, the proximity detection unit being operable to emit ranging signals through the transducer and to receive reflected signals through the transducer to determine the position of an object within a ranging area adjacent to the structural portion. The system further includes an alarm device coupled to the proximity detection unit that is responsive to a signal generated by the proximity detection unit. In another embodiment, a method includes determining a distance between the ground service vehicle and a selected structural portion of the aircraft when the vehicle is positioned in a ranging area about the aircraft. The method further includes generating a proximity alarm based upon the distance.

An internet-connected service system is provided for facilitating communication across the internet between image-sending and image-receiving systems that have dial-up internet access. The image-sending system, after connecting to the internet, sends a communication request to the service system and the latter is then responsible for waking up the image-receiving system. Upon being woken up, the image-receiving system connects to the internet and contacts the service system. The service system then transfers the current network address of at least one of the systems to the other thereby enabling direct communication to be established between the image-sending and image-receiving systems.

Metering of a data transfer operation between two end systems across a communications infrastructure is done by having at least one of the end systems send a metering message to a service system. Both end systems can be set to send respective metering messages to the service system at the conclusion of the transfer operation. Metering messages can also be sent on an on-going basis during the course of the transfer operation by one or both end systems; in this latter case, the end system or systems involved preferably maintain a connection with the service system throughout the transfer operation. Metering can be in terms of pages sent.
