Abstract: Heat exchanger assemblies for electronic devices are disclosed. A heat exchanger assembly may include a heat transfer body that has a face that forms open passageways. A cover structure may be attached to the heat transfer body in a manner to enclose the open passageways, thereby forming a heat exchanger assembly that includes enclosed fluid conduits. In this regard, the enclosed fluid conduits may form complex and intricate patterns within the heat exchanger assembly that are tailored to the heat requirements of a particular application. Heat exchanger assemblies as described herein may be thermally coupled to a center waveguide section of a spatial power-combining device. The enclosed fluid conduits may be tailored based on locations of amplifiers within the center waveguide section to provide improved thermal operation of the spatial power-combining device.

Abstract: A ventriculoperitoneal shunt includes a proximal catheter, a distal catheter, a shunt valve operably coupling the proximal catheter to the distal catheter, and a contrast container containing contrast material configured to change acoustic impedance proportionally to a change in pressure applied to the contrast container.

Abstract: A method for encoding domain name information into flow records includes receiving a flow record. The flow record includes initial network flow information in a standard flow record format including at least a source address and a destination address. Domain name information associated with each of the source address and destination address is retrieved from a database. The domain name information is encoded into the received flow record while maintaining the initial network flow information to yield an enhanced flow record.

Abstract: A system for pari-mutuel wagering on actual past events includes, in one embodiment, game terminals and a game server, all couplable to a network. The game terminals are configured to receive respective initial pari-mutuel wagers on a historic gaming event from respective players. The game terminals are further configured to receive respective winner selections for the historic gaming event for respective players. The game server is configured to randomly select the historical gaming event from a database and determine respective payouts for the game terminals based on results of the historical gaming event and the respective winner selections. The game server is further configured to admit at least one of the respective players to a bonus game, provide a bonus pool for the bonus game, and determine bonus payouts from the bonus pool to the at least one of the respective players based on bonus game results.

Abstract: Systems and methods relate to indexing of performance and cost of workloads in a computing environment. The computing environment may include a virtualized computing environment. According to some embodiments, a performance index relating to a plurality of workloads executing in the computing environment may be generated, where the performance index is based at least in part on performance and cost of use of one or more resources in the computing environment by the plurality of workloads. The index may be normalized. If the performance or cost of a particular workload departs from an expected performance or cost determined from the average performance and/or cost in the computing environment, resources may be reallocated to the workloads such that the performance or cost of the workload is closer to its expected performance or cost based on the performance index.

Abstract: A micro bubble generating system includes a shell having a well for retaining a first liquid to immerse an object. A micro bubble apparatus is provide to the shell for providing a pressurized mixture of a second liquid and a dissolved gas into the well so as to create a plurality of micro bubbles within the first liquid for engaging the object.

Abstract: A method to mitigate attack by an upstream service provider using cloud mitigation services. An edge detection device, which located at the subscriber's network edge, is able to communicate information via status messages about attacks to an upstream service provider. The service provider is then able to mitigate attacks based on the status messages. There is a feedback loop whereby the amount of dropped traffic by the service provider is added to the network traffic to keep the mitigation request open and prevent flapping. Likewise, the detection device includes time-to-engage and time-to-disengage timers to further prevent flapping.

Abstract: Novel subsea excavation apparatus and methods that exert force between a subsea anchor point and an excavator using a subsea actuator. In some examples the subsea actuator is attached to an anchor point on the seabed and the excavator directly. In other examples, a guide frame is anchored to the seabed to provide anchor points fixed relative to the seabed and the subsea actuators are attached to the guide frame and the excavator. In further examples, the subsea actuators can be attached to the excavator through a carrier frame or other excavator guides rather than directly to the excavator.

Abstract: A downhole logging tool and method of use for analysing portions of a seafloor borehole in seafloor drilling operations are provided. The downhole logging tool h an underwater chassis housing a power system and sensors including at least a conductivity sensor and a magnetic susceptibility sensor which, preferably, analyse the walls of the borehole. An automatically actuated switch, preferably actuated magnetically, provides power to the sensors from the power system when the downhole logging tool is not located in a designated portion of a seafloor drilling rig (e.g. when the tool is in use traversing a borehole) and removes power when the downhole logging tool is located in the designated portion of the seafloor drilling rig (e.g. when the downhole tool is not in use).

Abstract: Methods and systems for efficient query rewriting and the like are described here. One such described method comprises: offline mapping frequently-seen search queries to rewritten queries that may be better for searching; offline caching the mapping in a cache memory; and upon receiving a search query from a user similar to one of the mapped search queries, obtaining a corresponding rewritten query from the mapping in the cache memory based on predetermined conditions, and issuing a search of the rewritten query to the backend data system in order to avoid having to issue a search query to the backend data system twice while the user is online.
