  • Patent number: 8239520
    Abstract: Network service operational status monitoring methods and apparatus are disclosed. Responsive to a service status request associated with a network service, an operational status of the network service is determined by an intermediary between a service status requester and the network service. The operational status is a service-specific operational status of the network service in some embodiments. Operational status may be determined through a multi-level procedure in which subsequent levels after a first level of the multi-level procedure are or are not performed depending on a result of a preceding level of the procedure. A multi-level procedure may involve a service connectivity check and a service operational check, for instance.

  • Patent number: 8228510
    Abstract: An improved dimensional detection system is portable and can be used to characterize a workpiece. The dimensional detection system employs as few as a single focused light source and as few as a single camera along with a calibration data set to convert the illuminated pixels of an image of a beam on the workpiece into a cloud of real world points in space on an outer surface of the workpiece. The cloud of points can be processed to characterize the workpiece, such as by determining the right hexahedron that would encompass all of the real world points in space and which could be used to determine a dimensional weight of the workpiece.

  • Patent number: 8228194
    Abstract: An energy harvesting circuit has an active automatic tuning circuit to search for broadcast frequencies in a band of interest and selecting only those broadcast signals received with sufficient RF strength to be used in energy harvesting. This circuit would provide power storage devices with a circuit that has a means to select the ambient RF that can maximize or enhance the performance of an RFID circuit by increasing the amount of energy for harvesting. This automatic tuning would enable a power storage devices charger circuit to move from location to location without manual tuning of the circuit and increase the effective range of an RFID circuit.

  • Patent number: 8222555
    Abstract: An improved circuit breaker and arc chute has a shield apparatus that includes a number of plate-like shield members that have elongated openings formed therein to receive portions of arc plates therethrough. The portions of the arc plates that pass through the shield member are received in receptacles of a support apparatus that supports the arc plates. The arc plates are themselves configured to retain the shield members against the support apparatus to protect the support apparatus from damage in the event of an electrical arc. Advantageously, the retention of the shield members between portions of the arc plates and portions of the support apparatus enables the shield members to be held in place without the use of adhesives or separate fastening systems.

  • Patent number: 8214451
    Abstract: Network service version management techniques are disclosed. Service access information, which is associated with access to a network service by a network service user, may be destined for a particular version of the network service. A determination is made as to whether a different version of the network service is accessible by the network service user. If so, then a further determination is made as to whether to select the different version of the network service to process the service access information. Any inconsistency between versions of the network service, such as different information requirements, can be handled by transforming received service access information. A replay function may also be provided, to have service access information again processed by the same or a different version of a network service. This function may be useful, for example, where a version of a service is rolled back or for debugging.

  • Patent number: 8212646
    Abstract: The present invention relates to a fuse assembly for rapid interruption of a prospective fault current. The fuse assembly includes a plurality of splitter plates. A plurality of foil elements extend between a pair of terminals and are physically supported by the splitter plates. A pair of parallel busbars are in series with the foil elements and generate a magnetic field that is substantially perpendicular to the current flowing in the foil elements. In the presence of a prospective fault current, the foil elements will melt and at arcing inception an electromagnetic force developed as a result of interaction between the magnetic field and the arc current will push the molten foil elements into the splitter plates. This increases the arc length and hence the arc voltage. At least the foil elements and the splitter plates are preferably located in flowing liquid dielectric such as MIDEL 7131, for example.

  • Patent number: 8214043
    Abstract: An electronic medical monitoring and treatment apparatus allows a person access to a medical professional (MP) who can monitor, diagnose and treat the person from a remote site. The apparatus includes a medical monitoring and treatment device (MMTD) coupled to an electronic adapter designed to communicate with a local, first transmitting/receiving (T/R) device which, in turn, is adapted to electronically communicate with a remote, second transmitting/receiving (T/R) device used by the MP. The MMTD may comprise a cardiac treatment circuit for effecting cardiac pacing and/or defibrillation and a cardiac signal circuit for receiving cardiac signals. The cardiac signals are (1) transmitted from the signal circuit to the second T/R device for evaluation by the MP, (2) the MP may transmit a control signal to the treatment circuit, and (3), in response thereto, the treatment circuit may generate one or more electrical pulses for treatment of the person.

  • Patent number: 8205694
    Abstract: The method and apparatus consist of a robot body having at least two, but preferably six appendages. The appendages are organized into appendage groups of one to six appendages. The appendages are linked mechanically into groups of two or more and each group is actuated using a single drive actuator. A selective engagement mechanism is used to selectively engaged and disengage one or more appendages at a time in a way that allows for at least one appendage and at most all but one appendage per group to be engaged to a group's drive actuator. When the appendage is disengaged it is preferably locked in place to resist a reasonable force applied to them externally, such as the force equivalent to the weight of the robot.

  • Patent number: 8204720
    Abstract: Graph-based modeling apparatus and techniques are disclosed. Based on a model including model nodes that represent components of a modeled system, operational dependencies between model nodes, and model edges that interconnect the nodes and represent relationships between the components in the modeled system, subset computations are performed to compute subsets of the model nodes that can impact operational dependencies between other model nodes. When the model changes, a determination is made as to whether an incremental subset computation should be performed for one or more particular operational dependencies between model nodes in the changed model, and if so, an incremental subset computation is performed. Otherwise, a full subset computation or no subset computation might be performed. In this manner, model changes are considered on a case-by-case basis to determine an extent, if any, to which subsets should be re-computed.
