摘要： An apparatus for determining blood clotting capacity comprises an actuator to cyclically move a member within a sample of blood received in a well in a tray and one of a deflection sensor and a position sensor to determine the position of the wetted member upon being acted upon by the actuator. The theoretical position of the wetted member, as determined using a known actuator force and wetted member physical data, is compared to the sensed deflection or position of the wetted member, and the resistance to movement of the wetted member caused by the blood is determined and correlated to a clotting capacity.

摘要： An analysis apparatus includes a detector and a determination unit. The detector detects, for a target particle, a direction of a surface that is in proximity to the target particle. The determination unit determines the target particle to be a surface particle in a case where the number of other particles within a predetermined region extending in the direction of the surface is smaller than a threshold.

摘要： A system and method for measuring physical properties of non-Newtonian fluids, such as fluids containing dispersed solid particulate material and having a yield stress. A fluid resistance member is moved through the non-Newtonian fluid sufficiently slowly that viscous drag on the member is negligible and fluid resistance is essentially due to the yield stress of the fluid. The torque required to maintain the movement of the member through the fluid is measured, and at least one physical property, other than apparent viscosity of the fluid, is determined by employing a known relationship between the measured torque and the physical property of interest.

摘要： A rotational viscometer contains a measuring shaft that can be rotated at a specified rotational speed, a measuring part that is carried by the measuring shaft and that can be lowered into a sample, and a detection unit for determining the angle of torsion of the measuring part relative to the driven part of the measuring shaft. Accordingly, a twistable element is inserted into the measuring shaft, preferably in the section of the measuring shaft close to a motor. The detection unit is moved along with the shaft and determines the relative twist or the angle of torsion (twist) between the shaft part located on the motor side relative to the twistable element and the shaft part located on the measuring-part side. The output signals of the detection unit are fed to an evaluation device as the basis for determining the viscosity of the sample.

The first end is fixedly located on the body region. The flexible element includes at least a first layer having a first coefficient of thermal expansion and a second layer having a second, different coefficient of thermal expansion.

The resistance of a first portion of the electrical heater element adjacent the first end can be greater than the resistance of a second portion of the electrical heater element further from the first end. The device can include a heater controller arranged to supply an electrical pulse having a duration less than 5 ms to the electrical heater. The device can include a second, reference flexible element having a first end and a second end, with the first end fixedly located on the body region.

摘要： An apparatus and method is shown for determining the pumpability limit, freeze point and/or pour point of liquids, particularly fuels, at sub-ambient temperatures. A sample is placed in a viscometer which viscometer is rapidly cooled by a chiller. During cooling, after some measurements of temperature and viscosity, further temperatures and viscosity are approximated using the least squares method, which temperature and viscosity are subsequently measured to determine the pumpability limit. Continuation of the method will also give the freeze point and pour point of the sample being tested.

摘要： The viscometer provides a viscosity value (Xη) which represents the viscosity of a fluid flowing in a pipe connected thereto. It comprises a vibratory transducer with at least one flow tube for conducting the fluid, which communicates with the pipe. Driven by an excitation assembly, the flow tube is vibrated so that friction forces are produced in the fluid. The viscometer further includes meter electronics which feed an excitation current (iexc) into the excitation assembly. By means of the meter electronics, a first internal intermediate value (X1) is formed, which corresponds with the excitation current (iexc) and thus represents the friction forces acting in the fluid. According to the invention, a second internal intermediate value (X2), representing inhomogeneities in the fluid, is generated in the meter electronics, which then determine the viscosity value (Xη) using the two intermediate values (X1, X2). The first internal intermediate value (X1) is preferably normalized by means of an amplitude control signal (yAM) for the excitation current (iexc), the amplitude control signal corresponding with the vibrations of the flow tube. As a result, the viscosity value (Xη) provided by the viscometer is highly accurate and robust, particularly independently of the position of installation of the flow tube.
