Disclosed is a device and method for measuring the magnitude of a seepage force and its influence on effective stress of a formation. The measuring device includes a lower bearing platform having a pressure testing device fixed on an upper part thereof, and a water storage chamber mounted with a seepage water discharge pipe. A confining pressure loading chamber is mounted on the upper part of the lower bearing platform, and the lower bearing platform is used for placing a sample which has 11 measuring points distributed at equal intervals on an outer wall thereof. An upper and a lower permeable pressure-bearing steel sheet are placed on an upper and a lower end surface of the sample, respectively. The invention can improve the validity and accuracy of measurement and make the calculation result of the test more accurate.

A system and method including a weighing scale configured to measure a starting weight at a start time of a vaporizer chamber with a vaporizable liquid, the weighing scale configured to measure an ending weight at an end time and a controller configured to determine a vapor flow rate out of the vaporizer chamber based on a difference between the start time and the end time.

A fluid collection and measurement container includes a first wall and a second wall disposed opposite the first wall. The second wall is secured to the first wall and the first wall and the second wall define an expandable volume therebetween. A first electrolytic element is disposed on the first wall and a second electrolytic element is disposed on the second wall. A first terminal is connected to the first electrolytic element and a second terminal is connected to the second electrolytic element.

A weigh belt assembly includes a weigh belt that has first and second spaced apart rollers and an endless belt trained around the rollers to present a belt run configured to support particulate material. The rollers each have a rotational axis. The assembly also includes a belt drive operably coupled with at least one of the rollers for rotation thereof in order to move the belt run in a direction toward the second roller. The assembly also includes apparatus for delivery of quantities of particulate material onto the moving belt run at a position between the first and second rollers. The assembly further comprises a pivot assembly including a shiftable component operably coupled with the weigh belt in order to permit pivoting and downward deflection of the weigh belt under the load of the particulate material deposited on the belt run. A device for measuring the load experienced by the weigh belt during the deflection thereof is provided. A method of determining the flow rate of a particulate material and/or the total weight of material delivered using a weigh belt is also disclosed.

A bottle according to an exemplary aspect of the present disclosure includes, among other things, a sidewall, at least one cap removably attached to the sidewall, and a control unit. The control unit is configured to determine whether fluid expelled from the bottle is consumed by a user.

Disclosed herein is a cell harvesting instrument suitable for concentrating cells from a source suspension of cells and/or washing said cells, the instrument comprising: a housing for accommodating mechanical elements including at least one fluid pump, at least one valve; and a processing kit removably insertable into the housing, said kit including a generally flat frame having or supporting plural sealed fluid paths arranged in a generally flat plane and such that fluids in the paths do not contact said mechanical elements, wherein at least portions of the fluid paths comprise flexible tubes, the outer surfaces of which are manipulateable by the or each fluid pump, to provide fluid flow in one or more of the paths and/or by the or each valve to restrict fluid flow in one or more of the paths. In an embodiment, the kit comprises also a fluid processing reservoir and a filter suitable for separating cells from fluid in said paths. A transfer mechanism for moving and weighing the fluid processing reservoir is disclosed also.

Embodiments are described that relate to flow rate measuring systems that may be used in cell expansion systems (CES) and in methods for controlling fluid input into systems such as a CES.

To accurately calibrate fluid control equipment. A flow rate calculation system includes: a container in which gas is enclosed; a weight measurement part on which the container is disposed; a gas line which connects the container and fluid control equipment and in which the gas flows; and an enclosing line for enclosing the gas in the container disposed on the weight measurement part, thereby allowing the gas to flow from the container to the fluid control equipment or from the fluid control equipment to the container in a state that the container is disposed on the weighing measurement part, and calculating a flow rate of the gas flowing to the fluid control equipment based on an output value outputted from the weight measurement part, and the container and the weight measurement part are adapted to be placed in a decompressed decompression chamber.

A method of displaying a predicted state of a medical apparatus, and a medical apparatus employing the method are disclosed. The method comprises receiving a sensor signal from a sensor of the medical apparatus, filtering the sensor signal by an adaptive filter such that a predicted signal is achieved, determining a state from the predicted signal, and displaying an indication through a user interface of the medical apparatus based on the determined state.
