  • Solid ink stick with retrieval feature
    Patent number: 8366255
    Abstract: A solid ink stick for use in an imaging device, such as a phase change inkjet printer, is provided. The solid ink stick has a retrieval feature located on a top surface thereof. When the ink stick is incorrectly loaded through the insertion opening of a feed channel of the printer, the retrieval feature has a vertical dimension such that the ink stick can be grasped, such as by two fingers of a user, to remove the ink stick through the insertion opening. The retrieval feature generally includes two lower surfaces interconnected with at least one upper surface.

  • Solid ink stick with interface element
    Patent number: 8366256
    Abstract: An ink stick for use in a phase change ink imaging device has a protrusion with a predetermined height that is configured to enable a sensor in an ink loader of the imaging device to detect the height of the protrusion. The predetermined height of the protrusion corresponds to a control parameter for the imaging device.

  • Scalable Database Management Software on a Cluster of Nodes Using a Shared-Distributed Flash Memory
    Publication number: 20120259889
    Abstract: A distributed database system has multiple compute nodes each running an instance of a database management system (DBMS) program that accesses database records in a local buffer cache. Records are persistently stored in distributed flash memory on multiple storage nodes. A Sharing Data Fabric (SDF) is a middleware layer between the DBMS programs and the storage nodes and has API functions called by the DBMS programs when a requested record is not present in the local buffer cache. The SDF fetches the requested record from flash memory and loads a copy into the local buffer cache. The SDF has threads on a home storage node that locate database records using a node map. A global cache directory locks and pins records to local buffer caches for updating by a node's DBMS program. DBMS operations are grouped into transactions that are committed or aborted together as a unit.

  • Mechanized feed channel barrier in a solid ink printer
    Patent number: 8272727
    Abstract: A method is implemented to control movement of a solid ink stick from an insertion port to a corresponding feed channel to help ensure that each feed channel in a plurality of feed channels contains only ink sticks corresponding to the feed channel. The method includes receiving solid ink sticks in an insertion port located at one end of a feed channel in the solid ink printer, identifying each ink stick received in the insertion port, and removing a passage barrier from the feed channel in response to the ink stick being identified as corresponding to ink configured for passage through the feed channel.

  • Proxies for Actively Managed Funds
    Publication number: 20120143785
    Abstract: Among other things, receiving public information about an actively managed fund, selecting a group of financial assets, determining a group of weights corresponding to the group of financial assets thereby determining a weighted group of financial assets, the weights being determined based only on the public information, and publishing the contents of the weighted group of financial assets, wherein an expected valuation of the weighted group of financial assets is within a threshold percentage of an expected valuation of the actively managed fund.

  • System for maintaining temperature of a fluid in a conduit
    Patent number: 8186818
    Abstract: A fluid transport apparatus maintains temperature of a fluid transported through a conduit. The fluid transport apparatus includes a fluid transport conduit that is selectively deformed by a pressure within a compressor conduit and allowed to return to its original shape by venting the pressure through a venting valve. The alternating pressurization and release of pressure from the compressor conduit moves fluid through the fluid transport conduit. A thermal conductor is associated with the fluid transport conduit to maintain the temperature of the fluid in the fluid transport conduit within a predetermined range.

  • System and method for transporting fluid through a conduit
    Patent number: 8186817
    Abstract: A fluid transport apparatus facilitates flow of fluid from a source to a receptacle. The fluid transport apparatus includes a fluid transport conduit for transport of fluid through the conduit, the conduit being coupled between a fluid supply and a fluid receptacle, a compressor conduit proximate the fluid transport conduit along a portion of the fluid transport conduit between the fluid supply and the fluid receptacle, and a pump coupled to the compressor conduit for injecting fluid into the compressor conduit, and a vent that is operated to selectively enable pressurization and venting of the compressor conduit to compress and decompress the portion of the fluid transport conduit proximate the compressor conduit to pump fluid through the fluid transport conduit.
