Patent application numberDescriptionPublished
20090309465INFUSION SYSTEM CONFIGURATIONS - Infusion system configurations and assemblies facilitate routing of infusion circuit tubing lines. Tubing lines are routed into and out from compartments of a shielding assembly for the infusion system, at locations which prevent kinking and/or crushing of the lines, and/or provide for ease in assembling the circuit. A plurality of the lines may be held together by a support frame to form a disposable infusion circuit subassembly, that can further facilitate routing of the lines.12-17-2009
20090318745SHIELDING ASSEMBLIES FOR INFUSION SYSTEMS - A shielding assembly for an infusion system includes a plurality of compartments and a door for each compartment, and provides a radioactive radiation barrier for the compartments. One of the compartments contains a radioisotope generator of the infusion system and another of the compartments may contain a waste bottle of the infusion system. An opening into each of the generator and waste bottle compartments may be oriented upward, and the opening into the latter may be at a higher elevation than the opening into the former, for example, to facilitate independent removal and replacement of each. A door of at least one of the compartments, other than the generator compartment, when closed, may prevent the door of the generator compartment from being opened. A cabinet structure for the infusion system may enclose the shielding assembly and secure the generator.12-24-2009
20110071392INFUSION SYSTEMS CONFIGURATIONS - Shielding assemblies for systems that generate and infuse radiopharmaceuticals. The shielding assemblies include a sidewall that defines several compartments and provides a radiation barrier for the compartments and provides a passageway sized to accommodate routing of an eluate line from a radioisotope generator. One compartment is sized to contain the radioisotope generator. A second compartment is sized to hold a portion of an infusion circuit that may be an extension of the eluate line and may include a waste line and a patient line.03-24-2011
20110150579CONTINUOUS CHAMBER MASS CONFINEMENT CELLS AND METHODS OF USE THEREOF - The present invention relates to mass confinement cells that may be used in retaining walls and earth retention systems that has a natural earthen appearance or other aesthetic design and is resistant to damage and wear caused by the environment. The mass confinement cells are generally light-weight and include a continuous chamber that at least partially aligns with confinement cells positioned above and below, thereby allowing the intermingling of fill material between adjacent cells. The mass confinement cells are capable of accepting and retaining any type of filling material. The filling material provides weight, stability and security to a retaining wall constructed of such mass confinement cells.06-23-2011
20110162221LASER MEASUREMENT OF A VEHICLE FRAME - A laser measurement system operates to measure portions of a vehicle, such as a vehicle frame. The measurements are used, for example, to determine if the portions of the vehicle are bent or damaged. The measurement system includes a laser scanner and at least one target assembly that can be connected to a point of the vehicle. The laser scanner emits a laser beam that is detected by the target. Time and laser position information detected by the target are used to determine the location of the target, as well as the location of the point of the vehicle. The location of the point is then compared to an original location of the point to determine if damage has occurred.07-07-2011
