Abstract: A cymbal spinner, preferably a stand-mountable cymbal spinner, includes a housing having a base and an extension generally perpendicular to the base and a roller ball bearing mounted in the housing base, the roller bearing being mountable on a cymbal stand, and the cymbal spinner housing being capable of supporting a cymbal such that the cymbal is adapted to spin.

Abstract: The result of a first calculation may be determined by one of two alternative calculations. Each of the alternative calculations has an error associated therewith (due to factors such as measurement imprecision, rounding, etc.), and these errors propagate to the first calculation. However, there may also be error in the first calculation due to uncertainty about which of the alternative calculations applies. Such error can be taken into account based on the respective probabilities that the first and second calculations will apply, as well as the difference in the results produced by the two calculations.

Abstract: Real-time, geo-targeted and context-sensitive alerts are provided based on a stated objective. Factual information is collected over time. When a user needs the information, the user registers an objective and a geographic location. The factual information is scored for relevance, based on how closely the information fits the user's geographic location, and how relevant the information is to the user's stated objective. The most relevant information, as determined based on score, is pushed to the user in real-time.

Abstract: An information seeker can graphically define a spatial sub-region of a geographic area and a predicate to be applied to objects and/or events in that sub-region. A system can then provide and/or evaluate information about entities that fall within the sub-region and that satisfy the predicate. The boundary of the sub-region may be defined as an arbitrary polygon. The information to be provided can be raw information about the entities, or information that is derived from analysis of those entities that satisfy the spatial predicate. The display of information about object and/or events that fall within a sub-region can be displayed on what may be referred to as a spatial dashboard.

Abstract: Context-based routing of requests in a service-oriented architecture (SOA) is achieved by using context information received from service providers to make routing decisions. Service providers publish information about their context on a publish-and-subscribe channel. A router (e.g., a JBI normalized message router) subscribes to the channel to receive the context information, and may store the context information in a context repository. A consumer issues a service request specifying a context, and the router uses the context information received from the service providers to select the service provider that best satisfies the context. The request is then routed to the selected service provider.

Abstract: An entity is made the target of a communication—such as instant messaging, E-mail, or VoIP—based on a specification of context that the entity satisfies. A user (or other type of entity) who wishes to communication with one or more entities that satisfy a particular context specifies that context at the time the communication is to be sent. A system resolves the context by ascertaining which one or more entities satisfy the context, and the communication is sent to the ascertained entities. In one example, a user can specify that a message is to be sent to an entity at a particular geographic location, and the system chooses the one or more entities that are nearest to the specified location.

Abstract: A method and apparatus for dynamically discovering and communicating data in a communications network are described. A broker in a communications network receives a communication from a first service provider over the communications network, the broker comprising a metabroker and a service broker. The metabroker communicates messages to the service broker within defined time intervals to provide the service broker with any updated information about topics including a first topic. The broker sends information about the first topic to a first service consumer over the communications network within a first time interval from receipt of the communication comprising data about the first topic, and establishes peer-to-peer communication between the first service provider and the first service. The broker receives further communications about topics from multiple service providers over the communications network, and sends further data about to the first topic to the first service consumer.

Abstract: A method and system or determining a flight path for an aircraft between an initial point and a destination point are described. An airspace is divide into a set of grid cells, and a flight path is established between the initial point and the destination point. A cumulative threat risk value for each of the grid cells is calculated, and an allowable threat risk per grid cell is established based on a rule set. An intermediate point from which to deviate the flight path is identified based upon an analysis of the cumulative threat risk values of the grid cells, if the threat risk value of any of the grid cells intersecting the flight path exceeds the allowable threat risk. A deviation from the intermediate point to a new intermediate point is determined such that the new intermediate point has a cumulative threat risk value lower than or equal to the allowable threat risk per grid cell.
