An analyte detection system for non-invasively determining the concentration of an analyte in a sample is described. The detection system includes a window assembly consisting of a main layer adapted to allow electromagnetic radiation to pass therethrough, and a heater layer adapted to exchange heat to the sample. The system also includes a detector adapted to detect electromagnetic radiation emitted by the sample and passed through the window assembly. The analyte detection system also includes a control system in electrical communication with the heater layer and adapted to cause the heater layer to exchange heat to the sample. The main layer of the window assembly may be made from a variety of materials such as germanium, silicon, and chemical vapor deposited diamond.

A sample element includes first and second substantially parallel faces separated by an intermediate member. The parallel faces and the intermediate member at least partially define a sample chamber configured to hold a volume of fluid. The sample element further includes an optical path extending through the parallel faces and the intermediate member, such that electromagnetic radiation can propagate through the sample chamber. The sample element further includes an identifying compound disposed within or on at least one of the parallel faces. The identifying compound has at least one indexed optical absorbance feature, such that spectral analysis of electromagnetic radiation propagated through the sample chamber yields the indexed optical absorbance feature. Detection of the indexed optical absorbance feature in electromagnetic radiation propagated through the sample chamber indicates to an analyte detection system whether the sample element is configured for use with the analyte detection system.

Disclosed is a sample element for use in analyzing a concentration of an analyte in a material sample. The sample element comprises a sample chamber having at least one window, and a supply passage extending from the sample chamber. The supply passage defines a supply axis. The sample element further comprises a vent opening in fluid communication with the sample chamber. The vent opening is offset from the supply axis as the sample element is viewed orthogonal to the window.

356440000

A sample element configured to hold a material sample for determining a concentration of an analyte in the material sample. The sample element comprises a first window, a sample chamber partially defined by the first window, and a second, moveable window substantially aligned with the first window and the sample chamber. The second window is moveable from a first position in which the second window is spaced from the sample chamber, to a second position in which the second window covers and at least partially encloses the sample chamber.

A macrocell for use in a programmable logic device (PLD) providing for enhanced logic capability and reduced setup time. The preferred embodiment of the macrocell includes two look-up tables, for increased fan-in, and two flip-flops that increase fan-out, thereby doubling logic capability of the PLD without unacceptably increasing device size. Doubling the register count makes this PLD particularly suitable for applications employing high density sequential logic. Furthermore, a second register can be used for receiving fast input signals form an input to the PLD to reduce setup time.

A fluid handling system for use in bodily fluid analysis. The system comprises a first fluid handling module configured to interface with a main instrument. The first fluid handling module has a first fluid handling network and the first fluid handling network includes an infusate passage and an infusion fluid pressure member suitable for moving fluid within the infusate passage. The fluid handling system also has a second fluid handling module separate from the first module which is configured to interface with the main instrument. The second fluid handling module has a second fluid handling network and at least one sample analysis cell which is accessible via the second fluid handling network. The first and second modules are configured to interconnect and provide fluid communication between the first and second fluid handling network and the sample cells.
