  • Patent number: 6656158
    Abstract: A device for delivering fluid, such as insulin for example, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending towards an outlet connected to the exit port assembly. A threaded lead screw is received in the reservoir and a plunger has an outer periphery linearly slideable along the side wall of the reservoir and an inner periphery threadedly received on the lead screw. The plunger is non-rotatable with respect to the side wall such that rotating the lead screw causes the plunger to advance within the reservoir and force fluid through the outlet. The device also includes a dispenser having a return element for causes rotation of the lead screw, and a shape memory element. A changeable length of the shape memory element decreasing from an uncharged length to a charged length resets the return element.

  • Patent number: 6578607
    Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots.

  • Patent number: 6444173
    Abstract: A microfluidic device has a layer with a capillary break formed by a capillary sluice. The capillary sluice has a lower surface and an upper surface. A first electrode is disposed on the lower surface. The first electrode is coupled to the voltage source. A second electrode spaced a predetermined distance from the first electrode is coupled to the voltage source. A controller may be used to control the voltage applied to the electrodes. The controller may alter the operation of the microfluidic chip in response to fluid sensed at the electrodes.

  • Patent number: 6423273
    Abstract: A microfluidic device has a seal or other component between two adjacent layers. The seal or other component is formed of a sheet of material having a first thickness. The seal material has boss portions that have a second thickness greater than the first thickness. A plurality of holes are formed through the boss portion. A method for making the seal layer includes the step of thinning the seal material between a first film and a second film. Bosses are formed in the film. Holes are cut through the boss area. One film is removed from the seal material and the seal material is applied to a substrate. The seal material is cured to a substrate and the second film is removed from the seal material. Other components such as diaphragm may be formed using the above process without punching holes through the seal material.

  • Patent number: 5840256
    Abstract: The invention provides a plate having a plurality uniformly sized reaction cells formed in its upper surface, wherein the density of the reaction cells is at least about 10 cells per cm.sup.2. Preferably, the area of each of the openings of the reaction cells is no more than about 55% of the area defined by the multiplication product of (1) the pitch between reaction cells in separate rows and (2) the pitch between reaction cells in separate columns.

  • Patent number: 5677688
    Abstract: A full N-key rollover capability information entry device includes first and second sets of intersecting light guides oriented at an angle to one another which may comprise a mesh of waveguides that together form a self-supporting planar sheet of a substantially transparent material at the wavelength of light introduced into one end of at least one of the first and second sets of light guides. This permits each intersection to comprise a common portion of both a light guide of the first set and a light guide of the second set that intersect at that intersection. Detection of changes in the intensity of the light in at least one of the sets of light guides in response to key actuation that blocks a portion of the light at a certain intersection is indicative of that actuated key.
