Surface-micromachined microfluidic devices

Microfluidic devices are disclosed which can be manufactured using surface-micromachining. These devices utilize an electroosmotic force or an electromagnetic field to generate a flow of a fluid in a microchannel that is lined, at least in part, with silicon nitride. Additional electrodes can be provided within or about the microchannel for separating particular constituents in the fluid during the flow based on charge state or magnetic moment. The fluid can also be pressurized in the channel. The present invention has many different applications including electrokinetic pumping, chemical and biochemical analysis (e.g. based on electrophoresis or chromatography), conducting chemical reactions on a microscopic scale, and forming hydraulic actuators.

Fluid-borne contaminant protection using a filter assembly with a leading edge guide surface

Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is supported, the disc having a data recording surface and an outermost perimeter. A filter assembly includes a first filter adjacent to the data recording surface and a second filter disposed beyond the outermost perimeter of the disc. During disc rotation, fluidic currents are generated and impinge a leading edge guide surface of the first filter. A first portion of the currents passes into a gap between the first filter and the data recording surface. A second portion of the currents passes along the leading edge guide surface to the second filter. The first filter is preferably characterized as a chemical adsorbent filter which adsorbs vapor phase (gaseous) contaminants, and the second filter is preferably characterized as a pass-through recirculation filter which captures particulate contaminants.

Pressure control system for sealed enclosures

A pressure control system for a sealed enclosure may include opposing one-way valves to limit the differential pressure between the atmospheres internal and external to the sealed enclosure. The pressure control system may allow the internal atmosphere to vent out of a first one-way valve if the internal pressure exceeds the external pressure by a first predetermined pressure. The pressure control system may allow the external atmosphere to be drawn in through a second one-way valve if the external pressure exceeds the internal pressure by a second predetermined pressure. By allowing the exchange of gasses only when the differential pressure falls outside of a predetermined range, overall contamination may be reduced. By reducing the ingress of contaminants, such as dust, water, smog, and outgassed substances, performance may be improved and service life of components housed within the sealed enclosure may be extended.

Gimbaled micromechanical rotation system

The present invention is directed towards apparatuses for rotating a gimbaled platform with rotatable actuators. Gimbal springs comprised of component springs with compliant axes that intersect at a nonzero angle are coupled to the gimbaled platform.

Disc drive turbulent wind management

The disc drive housing encloses a spindle motor carrying a disc having a data surface. An actuator assembly includes an actuator arm carrying a head. The housing includes a first surface portion adjacent to the data surface of the disc. The housing also includes a plurality of surface portions that define a recess, which allows the actuator arm to move over the data surface of the disc. The plurality of surface portions include a sloped surface portion sloping away from the data surface and preventing wind generated by the disc rotating about an axis from separating from the sloped surface portion. Alternatively, a disc drive includes a housing that defines a recess. The housing encloses a disc mounted on a spindle motor that rotates the disc about an axis and thereby generates wind within the housing. An upstream surface portion and a downstream surface portion of the housing both face toward a data surface of the disc. A discontinuity, such as a step, between the upstream surface portion and the downstream surface portion causes a wind recirculation region within the recess. The disc drive also includes an actuator arm that carries a head, which the recess allows to move over the data surface of the disc. An actuator limiting device prevents the actuator arm from entering the wind recirculation region.

Financial transaction processing system

The automated method of the present invention provides an efficient arrangement for setting certain financial transactions using a debit point of sale transaction network, as opposed to routing over a credit network. The method and arrangement uses an onsite database of bank identification numbers to conduct a preliminary assessment of whether a particular card is debit capable, and appropriately processes the transaction information based on the preliminary assessment. The system preferably is also updated when a financial transaction is successfully completed as a debit transaction which the database did not initially identify as being debit capable. In this way, the database is continuously updated and over time, a more accurate database is achieved. The system can also be networked, such that information between databases is shard and improved, based on the network experience.
