20100074478 | METHOD AND APPARATUS FOR IRIS BIOMETRIC SYSTEMS FOR USE IN AN ENTRYWAY - A method and apparatus for designing an iris biometrics system that operates in minimally constrained settings. The image acquisition system has fewer constraints on subjects than traditional methods by extending standoff distance and capture volume. The method receives design parameters and provides derived quantities that are useful in designing an image acquisition system having a specific set of performance requirements. Exemplary scenarios of minimally constrained settings are provided, such as a high volume security checkpoint, an office, an aircraft boarding bridge, a wide corridor, and an automobile. | 03-25-2010 |
20110117673 | METHODS AND SYSTEMS TO COLLECT AND PREPARE SAMPLES, TO IMPLEMENT, INITIATE AND PERFORM ASSAYS, AND TO CONTROL AND MANAGE FLUID FLOW - Methods and systems to related to sample collection, assays, and fluid control and management. Methods and systems disclosed herein, and portions thereof, may be implemented alone and/or in various combinations with one another. | 05-19-2011 |
20110124129 | METHODS AND SYSTEMS TO CONTROL FLUID FLOW IN ACCORDANCE WITH A PREDETERMINED SEQUENCE - Methods and systems to perform sequential user-controlled fluidic assays, using substantially self-contained, portable, user-initiated fluidic assay systems, including user-initiated activation methods and systems. | 05-26-2011 |
20110143335 | METHODS AND SYTEMS TO CAPTURE COMPETITIVE MOLECULES - Methods and systems to capture competitive molecules, such as to reduce false positives in an assay. Competitive molecules may be captured in a fluid moving through a portable point-of-care diagnostic assay system. | 06-16-2011 |
20110151432 | METHODS AND SYSTEMS TO COLLECT AND PREPARE SAMPLES, TO IMPLEMENT, INITIATE AND PERFORM ASSAYS, AND TO CONTROL AND MANAGE FLUID FLOW - Methods and systems to related to sample collection, assays, and fluid control and management, including methods and systems to implement hand-held portable assays, to activate an assay system, to collect and prepare samples, to capture antibodies, and to trap or capture gas bubbles. Methods and systems disclosed herein, and portions thereof, may be implemented alone and/or in various combinations with one another. | 06-23-2011 |
20110151486 | METHODS AND SYSTEMS TO PREVENT GAS BUBBLES FROM INTERFERING WITH FLOW OF FLUID THROUGH A MEMBRANE REGION - Methods and systems to remove gas bubbles from liquids and to improve uniform fluid flow through a region of a membrane in a microfluidic device, including to reduce, remove, and/or prevent gas bubbles on a surface of a porous membrane. An example membrane bubble trap system may include a fluid channel connected to a bubble pathway that surrounds an opening sealed with a membrane. The bubble pathway may be configured to collect bubbles in fluid that passes through the membrane through buoyancy forces and through a directional feature of a curved surface placed above the membrane. | 06-23-2011 |
20110152720 | SAMPLE PREPARATION METHODS AND SYSTEMS - Methods and systems to prepare a sample, including a relatively small amount of a biological sample, and to mix the sample with preparation fluid stored in a device. The device may include multiple fluid chambers and a stepped plunger to force a fluid in at least one of the chambers into a sample receiving chamber and then to a storage chamber. Methods and systems disclosed herein may be implemented to collect and controllable mix a sample for analysis and/or storage. | 06-23-2011 |

20100015646 | PORTABLE, POINT-OF-CARE, USER-INITIATED FLUIDIC ASSAY METHODS AND SYSTEMS - Methods and systems to perform point-of-care, user-initiated fluidic assays, using substantially self-contained, portable, user-initiated fluidic assay systems. Exemplary assays include diagnostic assays and chemical detection assays. Diagnostic assays may include, without limitation, enzyme-linked immuno-sorbent assays (ELISA), and may include one or more sexually transmitted disease (STD) diagnostic assays. An exemplary assay system includes a housing having one or more fluid chambers, a fluid controller system to dispense fluid from the one or more fluid chambers, and a user-initiated actuator to control the fluid controller system. The actuator may be configured to move fluid controllers from functionally closed positions to functionally open positions, to control fluid flow from the fluid chambers. The fluid controller system may be configured to dispense fluids serially, and may be configured to mix a plurality of fluids. The housing may include one or more fluid paths amongst the fluid chambers and/or between the fluid chambers and an assay portion, and the fluid controller system may be configured to serially align fluid chamber outlets with corresponding fluid paths. The user-initiated actuator system may include an external user-operated trigger mechanism to initiate the actuator system. The actuator system may include a mechanical actuator system, and may include a compressible spring actuator system. The assay apparatus may include a display window to view assay results. Exemplary methods of preparing portable, user-initiated fluidic assay systems, and methods of using portable, user-initiated fluidic assay systems are disclosed. | 01-21-2010 |
