An apparatus for manufacturing a display device, the apparatus comprising: a droplet discharger comprising a nozzle configured to discharge a droplet; a first detector on a falling path of the droplet that falls from the droplet discharger and configured to detect a shape of the droplet; a second detector spaced apart from the first detector and configured to detect the shape of the droplet that falls from the droplet discharger; and a controller configured to calculate at least one of a volume of the droplet, a falling speed of the droplet, the falling path of the droplet, or a discharge angle, at which the droplet is discharged from the nozzle, based on results detected by the first detector and the second detector.

The present application provides a method for analyzing droplets on the basis of volume distribution including obtaining a total volume V of a sample containing target molecules based on a system prepared using the sample. The system is emulsified into droplets. A droplet system is obtained when the droplets obtaining the sample executes an amplification reaction. A droplet image of the droplet system is obtained. A total number n of droplets included in the droplet system is obtained based on the droplet image. A droplet volume distribution of the droplet system is obtained based on the droplet image. A number j of negative droplets among the n droplets is counted. A quantitative analysis is performed for the target molecules according to the total volume V of the sample, the total number n of droplets, the droplet volume distribution information, and the number j of negative droplets.

Provided is a sample manufacturing method that includes: a step of forming a hanging drop consisting of a liquid drop of a medium solution in a hanging state while causing at least one cell aggregate to be encapsulated in the liquid drop of the medium solution, the medium solution becoming substantially transparent upon gelling or solidifying; and a step of causing the hanging drop to gel or solidify by causing a promoting factor that promotes gelling or solidification of the medium solution to act on the hanging drop.

The present disclosure discloses an apparatus and a method for detecting first and subsequent drops of follicle fluid falling into a test tube during an aspiration process. A pair of optical devices (emitter and detector) is positioned at opposite side of the test tube. The emitter emits a beam of light towards the detector. As soon as a drop of the follicle fluid falls into the test tube, a signal processing circuitry detects a change in intensity of the light received by the detector. Further, the intensity of beam is compared with a pre-defined intensity. Based on the comparison, if the difference between the pre-defined intensity and intensity is greater than a pre-defined threshold value, the signal processing circuitry generates an electrical signal indicating the detection of the first drop of the follicle fluid falling into the test tube.

There is provided a urine analysis device for bed side monitoring of a patient, comprising: an inlet sized and shaped for fluid communication with a urine collecting tube that receives urine from a patient; a drip chamber through which the urine flows towards an outlet; at least one sensor that analyzes each drop of urine and estimates a respective volume of each drop; a timing element that measures a reference time for each drop; a program store storing code; and at least one processing unit coupled to the program store for implementing the stored code, the code comprising: code to calculate a urine output flow rate of the urine output flowing through the chamber according to the estimated volume of each drop of the urine and the reference time for each drop; and code to output the urine output flow rate.
