| 20090018416 | Analyte Concentration Measurement Device - A method for measuring concentration of an analyte in body fluid comprises acquiring a body fluid sample, emitting light into the body fluid sample, and detecting emitted light intensity on a plurality of optical paths through the body fluid sample. A plurality of optical filters are arranged in respective optical paths of the optical path plurality comprising at least a first optical filter with light absorption by an analyte and water and a second optical filter with light absorption to water alone. Light intensity passed through the first optical filter and passed through the second optical filter is measured and analyte concentration is determined based on a ratio of intensities detected at a detector in an optical path intersected by the first optical filter and detected at a detector in an optical path intersected by the second optical filter. | 01-15-2009 |
| 20090018483 | Infrared Sample Chamber - A body fluid analysis apparatus comprises a unitary housing containing a single-celled chamber and having an entry portal for communicating body fluid between a patient body and the chamber. A barrier coupled at the entry portal prevents selected components of the body fluid from entering the chamber. | 01-15-2009 |
| 20090047177 | LACTATE CONCENTRATION MEASUREMENT DEVICE - A lactate concentration measurement apparatus comprising a housing enclosing a sample chamber configured for holding a body fluid sample and measurement photo-optics that generate light and monitor light intensity along a plurality of optical paths in the sample chamber. The apparatus further comprises a plurality of optical filters aligned in respective optical paths of the optical path plurality comprising at least a first optical filter with light absorption by lactate and water and a second optical filter with light absorption to water alone. A logic determines lactate concentration based on a ratio of intensities detected at a first detector in an optical path intersected by the first optical filter and detected at a second detector in an optical path intersected by the second optical filter. | 02-19-2009 |

| 20090260846 | CABLE PROTECTOR WITH REMOVABLE DIVIDERS - A cable protector includes a channel recessed into, and extending along the upper surface of a base. A number of dividers can be removably inserted into the channel from above to divide the channel into a plurality of tracks for carrying cables that can be inserted from above. Alternatively, a removable tray with a desired number of dividers can be placed as a unit in the channel, instead of inserting individual dividers. A lid covers the channel and dividers to provide a surface for traffic over the cable protector. Sets of complementary fasteners, such a tabs and keyed slots, can be employed to removably secure the dividers in the channel of the cable protector. | 10-22-2009 |
