  • Patent number: 10688907
    Abstract: An automatic multi-air bag pneumatic inflation system for a trailer is also disclosed. The inflation system includes a system control unit coupleable to an air supply for controlling the flow of pressurized air in the pneumatic inflation system. The system control unit comprises an inlet for coupling to the air supply with an on/off valve for providing a flow of air, a primary regulator in communication with the flow of air and the on/off valve, an inflation pressure tank in communication with the flow of air and the primary regulator, a control valve in communication with the inflation pressure tank and/or primary regulator, and used to control the air flow, a function selection valve for selecting between inflation and deflation, and an outlet. A plurality of fill stations are fluidly coupled to the system control unit. One or more fill stations of said plurality of fill stations are fluidly coupled to an air bag for inflation and deflation thereof.

  • Publication number: 20080088835
    Abstract: Packaged fluid receptacles include: a plurality of fluid receptacles arranged one next to the other to form a composite structure having a top surface, bottom surface and end walls at a first end and a second end and having a longitudinal axis which extends through the end walls; and a removable support which contacts at least the top surface, bottom surface and end walls, the removable support including an attachment for applying a force to remove the support, preferably in a direction along the longitudinal axis. In a preferred embodiment, the support is one-piece and has a single attachment. Preferably, the packaged fluid receptacles are cuvettes usable in a clinical analyzer.

  • Publication number: 20050185176
    Abstract: A method for measuring the presence or concentration of an analyte in a sample by spectrophotometry: providing an open top cuvette having a sample with an analyte to be measured; providing a light source and a detector for detecting emitted light; taking at least two measurements that includes: (i) directing at least two beams of light from the light source to different locations on the cuvette; (ii) passing the at least two beams through the cuvette at their respective locations and through the sample to be measured; and (iii) measuring at least two respective emitted light beams with the detector; and comparing the at least two emitted light beams to determine if: all the emitted light beams should be disregarded; one or more of the emitted light beams should be disregarded; or the sample absorbances should be averaged. In a preferred embodiment, the method includes taking at least three measurements.
