  • Publication number: 20060206200
    Abstract: A vascular occluding device for modifying blood flow in a vessel, while maintaining blood flow to the surrounding tissue. The occluding device includes a flexible, easily compressible and bendable occluding device that is particularly suited for treating aneurysms in the brain. The neurovascular occluding device can be deployed using a micro-catheter. The occluding device can be formed by braiding wires in a helical fashion and can have varying lattice densities along the length of the occluding device. The occluding device could also have different lattice densities for surfaces on the same radial plane.

  • Publication number: 20050274384
    Abstract: Devices, such as medical devices for inhibiting conception, and methods of using and/or making these devices. In one aspect of the disclosure, a medical device has a delivery system and a first insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a first fallopian tube, and a second insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a second fallopian tube.

  • Publication number: 20050071143
    Abstract: Methods, computer systems, and computer readable medium for testing a plurality of models in order to classify a biological specimen. A determination is made as to whether a model precondition associated with a model in the plurality of models has been satisfied. The model is skipped when the model precondition has not been satisfied. When the model precondition has been satisfied, the first model is tested by selecting a calculation from the first model. The selected calculation is computed using cellular constituent abundance values from the biological specimen in accordance with a calculation algorithm set forth in the selected model. This selecting and computing is repeated for one or more calculations in the selected model. Then, each of these calculations is aggregated in accordance with an aggregation algorithm associated with the selected model. These steps are repeated for at least one other model in the plurality of models.

  • Publication number: 20050061329
    Abstract: Catheters for intrafallopian contraceptive delivery generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. One or more coils disposed along the catheter near its distal end enhance the ability of the catheter through a tortuous lumen, such as a fallopian tube, without significant kinking or narrowing of the inner diameter of the catheter. A coil also helps maintain the inner diameter of the catheter when it elongates during removal, thus facilitating delivery of a contraceptive device from the catheter. A variable-flexibility distal portion in some embodiments further enhances maneuverability and pushability.

  • Publication number: 20040221978
    Abstract: A web making machine is monitored to identify at least one cross-machine direction (CD) actuator that is developing local mapping problems. The identified CD actuator and a segment of surrounding actuators are probed to determine a performance curve for the actuator. The center of an insensitivity region of the performance curve is selected as an optimal mapping alignment setting for the identified actuator with the setting for the actuator being updated. Global smoothing may also be accomplished by probing a global smoothness factor to generate a corresponding performance curve that is then similarly used to select an optimal value for the smoothness factor.

  • Patent number: 6594283
    Abstract: A network communications device is arranged to have a fast throughput of data packets. This is achieved by recognising that, in protocols such as Ethernet, the first symbols in a data packet do not carry any data and therefore do not necessarily require to be properly carried through a communications hub. Rather, a known number of symbols are discarded from the start of a packet on receipt and replaced on re-transmission. This discarding reduces the reception delays particularly in bussed-architecture repeaters where bus arbitration must take place for each received packet.

  • Patent number: 6564117
    Abstract: The CD profile of a web of material being produced is monitored and controlled to update CD control settings on-line so that changes in the operation of a machine manufacturing the web can be corrected before significant profile deviations from a desired CD profile target result. Detected variances in the profile that satisfy a search criteria initiate searches for improved CD control settings. The CD control of the present application recognizes CD actuator mapping misalignments, determines improved CD control settings and applies the improved CD control settings to fine tune a CD controller and thereby improve upon or correct mapping misalignments. The CD control of the present application also recognizes non-smoothness of the setpoints of the CD actuators and controls the smoothness of the setpoints. Recognition and correction of either CD actuator mapping misalignments or CD actuator setpoint smoothness or both can be performed by the automated optimization of the present application.

  • Patent number: 6453916
    Abstract: An edge bead removal system and method is provided that employs a nozzle for applying edge bead removal solvent to an edge bead of a photoresist material layer disposed on a wafer. The nozzle eliminates solvent splash by lowering the angle of dispense to less than 20° as well as providing more degrees of freedom to the nozzle arm adjustments. Adjustment screws and a built-in protractor provide precision in setting the application angle. The nozzle includes a clamp design having a nozzle body clamp which holds the nozzle and a main shaft with a protractor assembly for up and down angle adjustments. A support bracket is coupled to the protractor assembly and allows for pivoting and side to side movement of the protractor assembly and the support bracket with respect to one another. A clamp connects a main arm structure that moves the entire edge bead removal nozzle assembly over the wafer.

  • Patent number: 6108217
    Abstract: A backup power circuit provides reserve power to a terminal device in the event of loss of power from the main power source. In the terminal device, the main power source is connected to a power circuit which generates two different voltage signals used by different circuits therein. The backup power circuit selectively stores energy from the higher voltage signal and supplies the stored energy to the power circuit when the main power fails, thereby allowing the power circuit to generate the lower voltage signal.
