20110214511 | FLUID ANALYSIS SYSTEM AND METHOD FOR OPERATION OF AN ANALYSIS SYSTEM - A fluid analysis system ( | 09-08-2011 |
20110308328 | SENSOR FOR DETECTING BUBBLES IN A LIQUID FLOWING THROUGH A FLOW PATH - The invention relates to a sensor ( | 12-22-2011 |
20120152032 | Drip Monitor - A low power, low cost system and method for the detection of flow disturbances in a fluid dripping system is disclosed. In one embodiment, a light source and a light detector configured to monitor the amount of light passing through a droplet while the droplet is suspended and later falls from the tip of a tube. In another embodiment, dripping fluid is monitored from a system maintained part of the time in a sleep mode to conserve power, the system waking up at predetermined times to determine from detected light whether the monitored system is functioning properly. | 06-21-2012 |
20130081478 | ENVIRONMENT PROVIDING DEVICE, ENVIRONMENT PROVIDING METHOD, AND PARTICLE DETECTING DEVICE EVALUATING METHOD - An environment providing device having a test chamber; a spraying device for receiving the supply of a gas flow to spray, into the test chamber, a fluid that contains particles; a flow meter for measuring a measured value for the flow rate of the gas flow that is supplied to the spraying device; a flow rate controlling device for controlling to a prescribed value, based on the measured value, the flow rate of the gas flow that is supplied to the spraying device; a timer for measuring a time interval over which the fluid that includes the particles has been sprayed into the test chamber; and a spraying-device-controlling device for stopping the spraying of the fluid that contains the particles after spraying a prescribed quantity of particles into the test chamber. | 04-04-2013 |
20140283620 | DEVICE, METHOD, AND SYSTEM FOR MONITORING THE DELIVERY OF FLUIDS THROUGH A DRIP CHAMBER - A device, method, and system are provided for monitoring the delivery of fluids through a drip chamber. The device includes an electromagnetic radiation (EMR) source and an EMR detector. A device body is employed to position the source and detector about the drip chamber so that the source and detector define an optical path across the drip chamber. A processor device is employed to detect fluid drops from differences between detector signal values separated by a lag time. The flow rate is determined from a drip factor and the detection of multiple drops. In the context of delivering intravenous (IV) fluids, a battery powered handheld monitoring device that includes the source, detector, device body, and processor device may be affixed to a drip chamber included in an infusion set. The device includes a user interface, including buttons, a display, and an audio speaker, for the input and output of information. | 09-25-2014 |

20160061641 | FLOW METER HAVING A BACKGROUND PATTERN WITH FIRST AND SECOND PORTIONS - A flow meter includes a first image sensor, a background pattern, and at least one processor. The first image sensor has a first field of view and is positioned to view a drip chamber within the first field of view. The background pattern is positioned within the field of view of the first image sensor, and the background pattern includes first and second portions. The processor is operatively coupled to the first image sensor and configured to: receive a first image from the first image sensor, and estimate at least one parameter of liquid within the drip chamber in accordance with a distortion of the background pattern caused by the liquid as indicated by the first image. | 03-03-2016 |
