Publication number: 20080067074Abstract: A device and method for increasing the mass transport rate of a chemical or electrochemical process at the solid and fluid interface in a fluid cell. The device includes a membrane in close contact with surface of the work piece, to separate the process cell into two chambers, so that fluid velocity at the work piece is controlled separately from the main cell flow. Thus the diffusion boundary layer is controlled and minimized by the rate that fluid is withdrawn from the work piece chamber.Type: ApplicationFiled: October 30, 2007Publication date: March 20, 2008Inventors: Qunwei Wu, Craig Brodeur, John Pillion, Jieh Shyu

Publication number: 20080033901Abstract: Embodiments disclosed herein provide restrictive-flow flow measurement devices, valve improvements and signal control devices and processes that control the flow of liquids, including control processes for single-liquid calibration. In some embodiments, a valve can be adjusted by application of fuzzy logic which involves quantizing input variables into the degree to which a small set of logical values is true. In one embodiment, variables related to flow rate and change in flow rate over time can be compared to membership functions to generate fuzzy inputs, based upon which fuzzy outputs can be generated.Type: ApplicationFiled: August 31, 2007Publication date: February 7, 2008Inventors: Christopher Wargo, J. Niermeyer, Jieh-Hwa Shyu, Craig Brodeur, William Basser

Publication number: 20060052904Abstract: One embodiment of the present invention can include a flow control device comprising an inlet, an outlet, a pressure loss element between the inlet and outlet, a pressure sensor located upstream from the constriction configured to measure a first pressure of a fluid flowing through the flow control device, a pressure sensor located downstream from the constriction, configured to measure a second pressure of the fluid flowing through the flow control device; and a controller coupled to the first pressure sensor and the second pressure sensor to generate a valve drive signal. The controller can generate a valve control signal based on a differential between the first pressure and the second pressure during a first mode of operation. The controller can also generate a valve control signal based on a measured pressure at a particular pressure sensor during a second mode of operation. The mode of operation can automatically switch.Type: ApplicationFiled: September 19, 2005Publication date: March 9, 2006Inventors: Craig Brodeur, Marc Laverdiere, Robert McLoughlin, J.

Publication number: 20030135159Abstract: A drug delivery device having a housing having an internal reservoir in communication with a drug delivery outlet via a fluid path. An expandable chamber disposed adjacent to the reservoir forces drug from the reservoir to the outlet when supplied with a gas. A flow regulating chamber, in communication with the fluid path, is capable of volumetric changes in response to temperature and/or pressure changes. An increase in the volume of the flow regulating chamber increases flow resistance to the outlet and thereby counteracts the corresponding increase in delivery rate resulting from the expansion of the expandable chamber due to the same volumetric changes in response to temperature and/or pressure. In a preferred embodiment, an electrical circuit has a current stabilizing element in electrical communication with an electrolytic cell which supplies the gas. A throttling device maintains a higher pressure in the device to reduce possible clogging of the fluid path.Type: ApplicationFiled: January 3, 2003Publication date: July 17, 2003Applicant: Elan Pharma International LimitedInventors: David Daily, Oz Cabiri, Mario Rozanowich, Miki Sahar, Jacob Stern, Diana Davidson, Izrail Tsals, Gilad Lavi, Avi Azoulay, Eran Shor, Craig Brodeur

Patent number: 6585707Abstract: A system adapted to be disposed between a rigid or semi-rigid device and human skin for reliably attaching the device to the skin for an extended period of time. The system includes a skin-contacting surface for adhering to human skin, and an opposed surface for attachment to a rigid or semi-rigid device. The system is attached along its opposed surface to a portion of the total area of the adjacent surface of the device. When the device is subjected to external stress, the stress is transmitted through the area of attachment and distributed to the unattached area. This minimises stress on the skin and reduces the chance of detachment from the skin.Type: GrantFiled: May 20, 1999Date of Patent: July 1, 2003Assignee: Elan Pharma International LimitedInventors: Oz Cabiri, David Katz, Mario Rozanowich, Haim Danon, Joseph Gross, Izrail Tsals, Craig Brodeur, Robert Etheredge

The stopper has a body having a perimeter for slidable engagement with the interior of a drug receptacle; an outer surface; and an inner surface facing the bottom of the drug receptacle, the inner surface shaped so as to trap any volume of gas located within the drug receptacle when the body is slidably engaged therein. The invention is further directed to a drug container having a hollow body for holding a liquid. The body has an open end and a closed end. The container also has a stopper slidably received in the hollow body, and a feature for entrapping any volume of gas within the container.Type: GrantFiled: October 12, 1999Date of Patent: February 18, 2003Inventors: Kevin Durand, Izrail Tsals, Craig Brodeur
