| 20090146635 | SYSTEM AND METHOD FOR IMPROVING INDUCTOR CURRENT SENSING ACCURACY OF A DC/DC VOLTAGE REGULATOR - The DC/DC voltage converter comprises at least one switching transistor. An inductor is connected to the at least one switching transistor. A pulse width modulation circuit generates control signals to at least one switching transistor responsive to a current control signal. A current sensor connected in parallel with the inductor senses current passing through the inductor. The sensor comprises a resistor and an NTC capacitor connected in series with the resistor. Circuitry for monitoring the voltage across the NTC capacitor generates the current control signal responsive to the monitored voltage. | 06-11-2009 |

| 20110111522 | NON-VISIBLE DETECTABLE MARKING FOR MEDICAL DIAGNOSTICS - Sample media for the analysis of analytes in a fluid test sample includes a carrier, at least one test field on the surface of the carrier including at least one reagent reactive with the analytes and capable of providing a detectable response. A non-visible bar code formed by at least two distinct non-visible marker fields is located on the carrier. The marker fields are configured to reflect electro-magnetic (EM) radiation within one or more ranges of non-visible wavelengths to form a coded sequence of reflectances correlated to identification of the sample media. | 05-12-2011 |

| 20100239137 | Two Dimensional Imaging of Reacted Areas On a Reagent - A system for reading an assay includes a camera and a processor. The assay is used as a test for the presence or absence of a reaction between a sample and a reagent. The assay is defined by a test area and a background area. The test area is, preferably, substantially circular with a diameter between about 0.1 mm and about 5 mm. The camera simultaneously captures a two-dimensional image of the test area and the background area. The processor determines a first color response from the background area and a second color response from the test area. The processor then calibrates the second color response according to the first color response and generates a result of the test according to the second color response. The system may also include a uniform field illuminator that provides a substantially uniform level of illumination across the assay. | 09-23-2010 |
