Abstract: In a system for applying sprayed droplets from a nozzle located in an environment with changing conditions affecting droplet size, a method of controlling droplet size comprising locating a droplet size measurement system at a location downstream from an outlet of the nozzle; receiving at a processor data describing droplets measured by the droplet size measurement system; determining at the processor a measured droplet size distribution from the data; inputting the measured droplet size distribution to a control algorithm in the processor; comparing the measured droplet size distribution to a target droplet size distribution; and outputting from the control algorithm a at least one signal corresponding to a parameter of the system for effecting a change in the droplet size distribution.

Abstract: An intravenous line lifter system for supporting one or more IV lines that extend between a patient and patient care equipment is disclosed. The system can include a first elongated support member couplable to a support for the patient care equipment, a second elongated support member coupled to the first elongated support member, a first line retention device coupled to the first elongated support member, and a second line retention device coupled to the second elongated support member proximate the second end of the second elongated support member.

Abstract: A method of measuring fluid flow including the steps of providing a light source including at least one LED, providing an image detecting element and defining an illuminated measurement space with an optical element located between the measurement space and the image detecting element. The measurement space is located optically in-line between the light source and the image detecting element. The method further includes the steps of providing a fluid flow through the measurement space, the fluid flow including particles, and illuminating the measurement space with the light source to induce light extinction from the particles comprising shadow markers of the position of the particles within the fluid flow. The image detecting element is used to detect the shadow markers produced by the particles to record displacement of the particles as a function of time corresponding to movement of the fluid flow. In a further aspect, the light source includes plural LEDs emitting different colors.
