Abstract: A stand-alone assay system for POC IVD that is fast, easy to use, inexpensive and delivers laboratory quality results for one or more target analytes from a small volume of unprocessed aqueous sample is disclosed. The stand-alone assay system is a disposable digital device. The stand-alone assay system integrates a sampling system that relies on users swiping a lanced finger containing, an unprocessed aqueous sample such as whole blood across a sample inlet to transfer or deposit the unprocessed aqueous sample on to a membrane filter or into a capillary. The stand-alone assays system may have one or more wireless modules for wirelessly transmitting assay information. The wireless modules can receive or transmit user information like patient ID or assay information like time, location or calibration values. The stand-alone assay system can display and transmit the assay information simultaneously.

Abstract: An integrated magnetic field generation and detection platform is described that is capable of manipulating and detecting individual magnetic particles, such as spherical super-paramagnetic beads, and providing biosensing functionality. The platform is implemented in an integrated circuit, a portion of the surface of which is functionalized with one or more biochemical agents that binds tightly (i.e., specifically) with a target analyte. The magnetic beads are similarly functionalized with one or more biochemical agents that that bind specifically with the target analyte. When a sample is introduced, magnetic beads that specifically bind to the integrated circuit can be separated from non-specifically bound beads and detected.

Abstract: A low-leakage circuit includes first, second, and third transistors, which may be P-channel or N-channel FETs. The first transistor provides an output current when enabled and presents low leakage current when disabled. The second transistor enables or disables the first transistor. The third transistor connects or isolates the first transistor to/from a predetermined voltage (e.g., VDD or VSS). The circuit may further include a pass transistor that provides a reference voltage to the source of the first transistor when the first transistor is disabled. In an ON state, the first transistor provides the output current, and the second and third transistors do not impact performance. In an OFF state, the second and third transistors are used to provide appropriate voltages to the first transistor to place it in a low-leakage state. The first, second, and third transistors may be used for a low-leakage current source within a current mirror, an amplifier stage, and so on.

Abstract: A PLL includes a charge pump, a loop filter, a VCO, and a calibration unit. The calibration unit performs coarse tuning to select one or multiple frequency ranges, performs fine tuning to determine an initial control voltage that puts the VCO near a desired operating frequency, measures the VCO gain at different control voltages, and derives VCO gain compensation values for the different control voltages. The calibration unit also pre-charges the loop filter to the initial control voltage to shorten acquisition time, enables the loop filter to drive the VCO to lock to the desired operating frequency, and performs VCO gain compensation during normal operation. For VCO gain compensation, the calibration unit measures the control voltage, obtains the VCO gain compensation value for the measured control voltage, and adjusts the gain of at least one circuit block (e.g., the charge pump) to account for variation in the VCO gain.

Abstract: Provided are a method, system, and program for a model publishing framework. An intermediate data structure is generated from a model to include elements providing information on the model, wherein the model defines an object oriented program design. A publisher registry has a plurality of registered publishers. One registered publisher is selected from the publisher registry to use to publish the model. The publisher includes formatting information to generate model output. The selected publisher accesses the intermediate data structure and generates output from the elements in the intermediate data structure according to the formatting information to provide a visualization of the defined model.
