摘要： A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

摘要： An automated bioreactor system for decellularizing an organ includes a main chamber for containing the organ. The system further includes a reagent chamber containing a liquid phase reagent. A reagent conduit delivers the liquid phase reagent to the main chamber, and a perfusion conduit delivers the reagent from the reagent outlet in the main chamber into the organ. A perfusion pump drives the flow of the reagent. A perfusion pressure sensor detects a pressure of the flowing reagent. A control system controls the perfusion pump to drive the flow of the reagent based on a received input representative of a desired pressure and a received input of the detected pressure. The control system may automatically perform all of the steps of a decellularization protocol based on sensor input. An automated waste decontamination system may also be provided.

摘要： The present invention relates to a nutrient solution recycling plant cultivation system, which recycles and supplies a cultivation nutrient solution and measures in real time the composition of each nutrient component to be added to a waste nutrient solution through a so-called soft sensor using measured values of pH, EC, temperature, turbidity, and weight and a previously constructed estimation model instead of an expensive high-performance analyzer, thereby minimizing nutrient solution consumption while meeting a required level of accuracy.

摘要： A lacrimal tear flow measurement device, and methods of manufacture and use, are described that includes a polymer microcapillary tube or similar structure having at least one end coated on the outside with soft silicone rubber and one end treated on the inside to be hydrophobic. The hydrophobic end keeps liquid from escaping or entering that end while allowing air to pass. The rest of the tube's insides may be hydrophilic or a neutral hydrophobe. As a Schirmer's test strip replacement, the entrance end of the device can be touched to the lacrimal lake of a patient's eye to collect suck up, or merely collect, tear fluid within the collection tube for weighing, volume measurement, or other analysis. Long-term collection devices for wear between doctors' visits can have a bypass channel allowing liquid to flow back onto the eye.

摘要： A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.

摘要： A system for preparing and administering a prescribed fluidic pharmaceutical compound, such as a chemotherapy compound, includes a scale having a platen. The scale is in communication with a user display for displaying an output of the scale. An image capture device having a field of view for capturing at least one image of an object placed on the platen is provided in communication with the user display for displaying the captured image. The platen may include a visual identifier for identifying a portion of the field of view of the image capture device. The platen may also include a tackifier or absorbent material. The platen may be formed of a light-transmissible material.

摘要： Methods and systems for tracking an object comprise a horizontal surface upon which objects are to be placed, a weight sensor disposed on one side of the horizontal surface, and a processor in communication with the weight sensor. The processor is adapted to detect a change in weight measured by the weight sensor, to associate the detected weight change with an identified object and with a location on the horizontal surface, and to confirm whether a cause of the weight change at the location on the horizontal surface corresponds to a proper handling of the identified object.

摘要： Methods and a system are provided for assessing postpartum hemorrhage risk and postpartum hemorrhage stages in a clinical setting. Generally, a clinician may indicate that the mass of several bloody items, indicated in type and quantity, is to be measured using a scale. The mass of bloody items is compared to the known unused dry mass of such items in order to accurately determine the quantitative blood loss (QBL) of a patient at the bedside. The cumulative QBL can be updated by weighing additional items. Based on the cumulative QBL, the patient's vital signs, and other factors, a corresponding hemorrhage stage is identified and communicated to the clinician. Recommendations specific to the hemorrhage stage are provided to a clinician. Some recommendations are selectable actions that trigger automatic placement of medical orders and notifications to relevant medical services, such as a blood bank or anesthesia.
