20080198360 | Transmission Spectroscopy System for Use in the Determination of Analytes In Body Fluid - A total transmission spectroscopy system for use in determining the analyte concentration in a fluid sample comprises a sample cell receiving area, a light source, a collimating lens, a first lens, a second lens, and a detector. The sample cell receiving area is adapted to receive a sample to be analyzed. The sample cell receiving area is constructed of a substantially optically clear material. The collimating lens is adapted to receive light from the light source and adapted to illuminate the sample cell receiving area with a substantially collimated beam of light. The first lens is adapted to receive regular and scattered light transmitted through the sample at a first angle of divergence. The first lens receives light having a first angle of acceptance. The first lens outputs light having a second angle of divergence. The second angle of divergence is less than the first angle of divergence. The second lens is adapted to receive light from the first lens and adapted to output a substantially collimated beam of light. The detector is adapted to measure the light output by the second lens. | 08-21-2008 |
20090021743 | Coaxial Diffuse Reflectance Read Head - Improved performance in reflectance photometry is obtained by employing an optical fiber to direct collimated light to a test area and to return both diffuse and specular light from the test area. Specular light is prevented from reaching a light detector by a spatial filter, while diffuse light is collected and measured. | 01-22-2009 |
20100009455 | Test Sensor with Under-Fill Protection - A test sensor for testing an analyte concentration in a fluid sample includes a pre-fill capillary, formed by a base and a lid of the test sensor, and a sensing capillary. The pre-fill capillary is in fluid communication with the sensing capillary. The pre-fill capillary is first filled with the fluid sample and a portion of the fluid sample then moves by capillary action to the sensing capillary for testing of the analyte concentration. | 01-14-2010 |
20100178703 | SINGLE-SENSOR METER SYSTEM WITH NO SENSOR HANDLING AND METHOD OF USING THE SAME - A single-sensor meter system for dispensing sensors for testing of an analyte concentration in a fluid comprises a container assembly and a single-sensor meter. The container assembly includes inner and outer cartridges. The inner cartridge includes a plurality of test sensors and a mechanical mechanism. The container assembly forms exactly one opening for dispensing the test sensors one at a time. The opening is covered by an end cap so as to assist in preventing or inhibiting moisture from entering the interior of the container assembly. The mechanical mechanism is adapted to advance the plurality of test sensors. The single-sensor meter is adapted to align with and operatively connects to the container assembly. The single-sensor meter includes a test-sensor extraction mechanism adapted to grip a test sensor and pull the test sensor through the opening to a dispensed position. | 07-15-2010 |
