  • Publication number: 20060235502
    Abstract: An intravascular delivery catheter includes a middle member or manipulator to ameliorate the effect of buckling of the graft cover during the tracking or positioning of the delivery device within a body flow lumen to deploy an exclusion device, such a stent graft. The delivery device/catheter includes a region or regions of lower resistance to bending than other portions of the delivery device, which are positioned, within the delivery device, to preferentially bend the delivery system at locations where buckling will have minimal effect upon the deployment of the exclusion device from the delivery system.

  • Publication number: 20060214025
    Abstract: A shower kit and apparatus includes a showerhead coupler and a sealed flexible water chamber, which are placed in line between in a shower stall between the shower arm and the showerhead. The showerhead coupler has a water source outlet for discharging water under pressure into the flexible water chamber and a water source inlet for receiving water under pressure from the flexible water chamber. The flexible water chamber has a sufficient volume capacity to absorb and smooth out momentary fluctuations or changes in water pressure by breaking up the mass of air that would otherwise fill the shower arm into small bubbles within the volume of water contained within the flexible water chamber, which mixture of water and bubbles is then sent out to the shower head and evacuated unnoticed.

  • Publication number: 20060175565
    Abstract: An electrically driven stepmotor valve assembly including separable annular stator and rotor-valve assemblies. The rotor-like assembly having a cylindrical housing adapted to slip fit inside a central, domed, stator cavity, with alignable locking members on these assemblies permitting rotary interlocking upon the slip fit assembly thereof. A sealing arrangement, in the vicinity of the open end of the stator assembly, peripherally seals the stator and rotor-valve assemblies relative to each other, when assembled, with the rotor housing having a locating plate ring portion which, in turn, supports an elastic sealing member that fits into a groove in a bottom wall of the stator housing. A plurality of differing sealing arrangement designs and structures, including sealing member reinforcing structures, are set forth for the sealing of the interlocked stator and rotor-valve assemblies relative to each other.

  • Publication number: 20060178157
    Abstract: Signals propagating on an aggressor communication channel can cause interference in a victim communication channel. A sensor coupled to the aggressor channel can obtain a sample of the aggressor signal. The sensor can be integrated with or embedded in a system, such as a flex circuit or a circuit board, that comprises the aggressor channel. The sensor can comprise a dedicated conductor or circuit trace that is near an aggressor conductor, a victim conductor, or an EM field associated with the interference. An interference compensation circuit can receive the sample from the sensor. The interference compensation circuit can have at least two operational modes of operation. In the first mode, the circuit can actively generate or output a compensation signal that cancels, corrects, or suppresses the interference. The second mode can be a standby, idle, power-saving, passive, or sleep mode.

  • Publication number: 20060159002
    Abstract: Signals propagating in one communication channel can generate crosstalk interference in another communication channel. A crosstalk cancellation device can process the signals causing the crosstalk interference and generate a crosstalk cancellation signal that can compensate for the crosstalk when applied to the channel receiving crosstalk interference. The crosstalk cancellation device can include a model of the crosstalk effect that generates a signal emulating the actual crosstalk both in form an in timing. The crosstalk cancellation device can include a controller that monitors crosstalk-compensated communication signals and adjusts the model to enhance crosstalk cancellation performance. The crosstalk cancellation device can have a mode of self configuration or calibration in which defined test signals can be transmitted on the crosstalk-generating channel and the crosstalk-receiving channel.

  • Publication number: 20050226353
    Abstract: A wireless communication system can comprise two or more antennas that interfere with one another via free space coupling, surface wave crosstalk, dielectric leakage, or other interference effect. The interference effect can produce an interference signal on one of the antennas. A cancellation device can suppress antenna interference by generating an estimate of the interference signal and subtracting the estimate from the interference signal. The cancellation device can generate the estimate based on sampling signals on an antenna that generates the interference or on an antenna that receives the interference. The cancellation device can comprise a model of the crosstalk effect. Transmitting test signals on the communication system can define or refine the model.

  • Publication number: 20050188271
    Abstract: A general rule-based technique is provided for generating a test case from an abstract internal test case representation. The abstract internal test case representation is based on a test case representation model that includes application states (state information), external interaction sequences (control flow information) and input data. The abstract representation in essence provides a platform independent representation of test cases. An application object model provides the representational capabilities required for capturing structural and behavioral properties of the application under test. Rules can be specified to define which application states (state information), external interaction sequences (control information) and input data sets should be used in the generation of the test case. Multiple data sets can be created and applied to support data-driven test case generation.

  • Publication number: 20050160322
    Abstract: A general technique using semantic analysis is provided that can be used for converting a specific automation test script (and its underlying test case), generated from generally available or proprietary test automation tools, into an abstract test case representation. The abstract test case representation is based on a test case representation model that includes application states (state information), external interaction sequences (control flow information) and input data. The abstract representation in essence provides a platform independent representation of test cases. An application object model provides the representational capabilities required for capturing structural and behavioral properties of the application under test. The abstract test case representation can be validated against and further enriched by specific object information from an application metadata repository.

  • Publication number: 20050081959
    Abstract: Disclosed is a method of preparing a micro-structured powder for bonded magnets having high coercivity, which is advantageous in terms of low preparation costs by recycling magnet scraps, simplified mass production, minimal environmental contamination by such a recycling process, and the preparation of stable anisotropic powders having high coercivity. Further, a magnet powder prepared by the above method is provided. The current method is characterized in that R—Fe—B type anisotropic sintered magnets or scraps thereof are crushed to prepare 50-500 ?m sized magnet powders, which are then mixed with 1-10 wt % of rare earth fluoride (RF3) powders and thermally treated at high temperatures (500-1100° C.) in a vacuum or an inert gas, to cause the change of matrix-near surface and grain boundary of the powders.
