Abstract:

A system and method are provided for modifying the effective reading range of an radio frequency identification tag. The tag, a chip based tag, includes an antenna and a chip in communication with the antenna. The chip includes circuitry including field effect transistors that can modify the effective reading range of the tag by modifying characteristics of the tag including the modulation depth of the backscatter signal, the impedance characteristics of the tag front end electronics, the power consumption characteristics and the threshold power-on voltage of the tag. These characteristics are change either temporarily or permanently in response to commands communicated to the tag from a radio frequency identification reader.

International Classification:

G06F 3/00

US Classification:

719312

Abstract:

Embodiments of the invention relate to message queuing. In one embodiment, a request from an application for retrieving a message from a queue is received. The queue is stored across multiple nodes of a distributed storage system. A preference with respect to message order and message duplication associated with the queue is identified. A message sequence index associated with the queue is sampled based on the preference that has been identified. The message is selected in response to the sampling. The message that has been selected is made unavailable to other applications for a given interval of time, while maintaining the message in the queue. The message is sent to the application.

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

An event-driven computer system for simultaneous management and deployment of software onto an application platform comprises one or more computing solutions, the system comprising: a processor for executing computer code and processing information; a memory for storing the computer code and information, the computer code comprising software tools. The software tools comprise: a behavior model editor for constructing a system model that represents the behavior of the application platform; the behavior model editor comprises behavior components, each behavior component representing an aspect of the application platform. The software tools further comprise: a topology model editor for constructing a visual topology model. This topology model editor comprises: a top level of nodes and lower level nodes, and represents a logical topology of the application platform, where each top-level node in the topology model represents at least one computing solution. In addition, the software tools comprise: a mapping algorithm for transforming one or more deployment units into execution units and for mapping one or more execution units to at least one computing solution; and a deployment protocol for distributing the one or more execution units over a network to at least one computing solution.

International Classification:

G06F 15/177

US Classification:

709220

Abstract:

A mechanism for declarative service domain federation uses a declarative approach to both the visibility aspect and the management aspect of service domain federation. Instead of manually exporting services, that is, selecting individual services from source domains to be visible in the target domain, using the present system, a federation architect uses a federation console to specify federation intent. The federation intent may include federation rule, query-based service group, and quality-of-service (QoS) policy. Based on the declared federation intent, a planning engine resolves the individual services based on the group query, generates the service visibility configuration, and creates the necessary service proxies and/or mediation objects to satisfy the goal. At runtime, a service monitor collects the performance metrics of federated services and dynamically adjusts the mediation/proxy configurations to maintain the QoS objectives specified by the federation architect.
