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, or outer surfaces of which are manipulateable by the or each fluid pump, to provide fluid flow in one or more of the pats 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.

The present invention relates to an urine specimen collection system in which the urine sample to be taken for the laboratory tests, can be collected without interrupting the patient while urinating. Present invention will transfer certain amount of urine into the specimen container by collecting the urine of the patient collected during the urination speed test. Thus, the specimen acquired from the urination speed test can be used in the laboratory tests. System will transfer the urine of the patient into a specimen container automatically by steps applied during the regular urination process and immediately after this process. System then will perform the cleaning of the urinated reservoir.

System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.

A substrate processing system includes: a measuring unit provided detachably with respect to a placement portion of a placement stage; a measuring jig for measuring a processing liquid; a liquid processing unit including a supplier which supplies the processing liquid to the measuring jig; a transfer mechanism for transferring the measuring jig between the measuring unit and the liquid processing unit; and a controller. The controller executes: a process of transferring the measuring jig in the measuring unit from the measuring unit to the liquid processing unit; a process of ejecting the processing liquid from the supplier to the measuring jig; a third process of transferring the measuring jig from the liquid processing unit to the measuring unit; and a fourth process of calculating an ejection amount of the processing liquid based on a measurement value in the measuring unit.

The nozzle is configured to dispense the powder selectively into the cylindrical hole, and the powder collector is configured to receive at least a portion of the powder from the discharge passage.

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.

A method of calibrating a mass flow sensor while harvesting grain includes sensing an accumulated mass of a portion of grain within the grain tank with a first sensor. A mass flow rate sensor is calibrated based at least in part on a signal of the first sensor.

Various embodiments of the present disclosure are directed to measuring methods for determining a flow rate of a process gas, contained in a gas pressure vessel charged with overpressure, escaping from the gas pressure vessel. In one example embodiment, the method includes: exerting a vessel weight force from the gas pressure vessel together with the contained process gas; compensating for the vessel weight force by means of a counterweight force exerted by a counterweight, or the counterweight force by means of the vessel weight force exerted by the counterweight, at least partially to a resultant measured weight force; determining the measured weight force at at least two points in time; and determining the flow rate of the process gas using the measured weight force determined at the at least two points in time.
