Abstract: An object-based locking mechanism is disclosed in which the requesting and granting of access to data is decoupled by the use of methods to regulate the data access. In one embodiment, a client object calls a request lock method of a server object when it desires access to data regulated by the server object. When the server object decides to grant access, it calls a lock granted method of the client object. Within the scope of the lock granted method, the client object has access to the data; when the client object returns the lock granted method, access is released. An object queue to manage data access with respect to a number of client objects for a server object is also disclosed.

Abstract: A method and system are provided for defining a search space of a community in which a client may search for resources. A client providing a resource registers the resource with a core. The core then lists the resource with an advertising service, which serves multiple cores. A client searching for a resource can search in the client's core and within the advertising service serving the clients core. In addition, a client searching for resources can define a community of advertising services remote to the client's core, then designate the community when sending an attribute-based search for computer resources to the client's core. In some embodiments, once a community is defined, a client can subscribe to an events within the community by searching for an event distributor within the community. The client is then notified of events occurring within the community that match the client's event subscription.

Abstract: A three dimensional structure is precisely positioned at a desired location. A viral model of the structure of interest is created and stored in a computer memory. Some time later, remote sensors are placed in selected positions on the structure of interest. The sensors are configured so as to provide real time location, attitude and orientation information regarding the structure and may consist of GPS remote units, tilt meters, gyro compasses, and pressure sensor. The position of each the remote sensors on the actual structure is also recorded in the computer memory so that the virtual model accurately reflects the configuration of the structure. As the structure is being positioned, the real-time location, attitude and orientation information produced by the remote sensors is monitored at a base station and used to update the virtual model. In this way, the virtual model accurately reflects the current location, attitude and orientation of the structure.

Abstract: A system enables a consumer to generate a filtering program based on criteria set forth by a system operator during run time. During system operation, the operator selects appropriate filtering criteria from a display screen associated with a respective consumer. Each consumer implements filtering criteria in a filtering program that is registered with a distributor. The filtering program may include simple true or false tests, or more complex tests. The distributor compiles each filtering program during registration and thereafter dynamically loads the compiled program before executing filtering queries.

Abstract: Identification information is extracted from a current broadcast of a piece or music or other type of information of interest to a user, and stored in a memory or other storage device, in response to a user command. The identification information includes sufficient information to identify at least one deliverable information item associated with the current broadcast, e.g., a CD or MP3 file which contains the particular piece of music. When the user later has access to a wired or wireless network connection, the extracted identification information is delivered over a network connection to a server which processes the delivered information to identify the deliverable information item associated with the broadcast. The user can then purchase the deliverable information item by appropriate interaction with the server. The extracted identification information may be stored in a removable memory device associated with a receiver which receives the broadcast.
