  • Patent number: 10228359
    Abstract: A method and an apparatus are presented for monitoring a concentration of a specific halogen in a body of water such as a spa or bathing unit for example. The apparatus comprises a housing in which is positioned an optical absorption analyzer for making first and second measurement of transmission of ultraviolet light from a light source emitting light at a specific wavelength. The second and first measurements are taken respectively before and after the ultraviolet light has travelled through a sample of water and are used to derive a concentration of the specific halogen. The derived concentration may then be communicated to a user using a display device and/or may be used to control operational components of a bathing unit for adjusting the concentration of halogen in the water.

  • Patent number: 8506799
    Abstract: A system for characterizing suspended particles in a water treatment facility is disclosed. The system uses an imaging array to take multiple images of the particles in a sample volume. These images are then processed to determine geometrical properties of individual particles in the sample. These geometric properties can then be used to identify properties of the sample volume such as particle volume concentration, particle number concentration, computed particle diameter, gravitational settling velocity, mass concentration, and computed particle volume.

  • Patent number: 8501015
    Abstract: A centrifuge for separating blood having a camera observing fluid flow, and a controller controlling the flow. The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct. “Final edge calculation” uses the points where the shade changes in the pseudo image, averages the radial displacement of these points for the interface position.

  • Publication number: 20130175000
    Abstract: A visual indicator device and method for determining the presence of oily contaminants in an aqueous stream are provided. The device includes a filtration status chamber for receiving and discharging the aqueous stream, and a transparent wall enabling viewing of the chamber interior. A fluid-pervious filtration media within the chamber is infused with an absorption composition at which the contaminant on contact with the media is immobilized. The media has a surface viewable through a transparent wall of the filtration status chamber, and the stream flow path causes the stream to impinge at the media via the surface, whereby the contaminants collect selectively at the media surface and are highly visible through the transparent wall.

  • Patent number: 8454895
    Abstract: This invention refers to continuous flow devices for detecting and/or removal of contaminants from a liquid stream. The device comprises a cartridge with an inlet and outlet for the liquid stream, a radiation incident and emerging wall portion and optically transparent support material packed in the cartridge such that a liquid stream can pass between voids or spaces formed within the optically transparent material, as well as a radiation source and detector. The support material comprises molecules for capturing at least one contaminant on the surface of the support material and each of the capture molecules comprises at least one reporter group which emits a signal upon binding of the contaminant. Another form of the invention refers to a rotatable support within the liquid stream.
