摘要： Hand-held optical thromboelastographic sensor and method of using the same for simultaneous assessment of multiple parameters of blood coagulation at a point-of-care. The sensor includes an optical system registering laser speckle intensities associated with portions of a blood sample delivered through a fluid switch to analysis chambers of a cartridge of the sensor, and data-processing circuitry programmed to derive the multiple parameters from speckle intensity. The circuitry may be part of a mobile device configured to operate without communication with a central server and/or data storage.

The IoT system including a smart gas user platform, a smart gas service platform, a smart gas sensing network platform, a smart gas object platform, and a smart gas device management platform. The method may be performed by the smart gas device management platform. The method may include: transmitting at least two sound waves of different frequencies at at least two time-dividing points and receiving at least two echo signals by the gas ultrasonic meter. The at least two time-dividing points may be determined at least based on time-dividing point correlation data; determining, based on the at least two echo signals, a gas flow difference; determining, based on the gas flow difference, whether a noise interference exists; and in response to a determination that the noise interference exists, adjusting a gas metering strategy.

摘要： A thrombelastography device, a heating apparatus, a blood coagulation analysis system, and a rotational angle measurement method are disclosed. The thrombelastography device consists of a plurality of thrombelastography device splits (2) that are horizontally arranged in parallel. The thrombelastography device split (2) comprises a worktable (4), a rack (5), a test bar (6), a tester (8), and a processor (9). The thrombelastography device overcomes the defect in the prior art that the measurement result of a thrombelastography device is inaccurate. The amount of reflected light is used as a reference for thrombelastographic evaluation, and thus the result is more accurate.

摘要： An example self-priming microfluidic structure can include a microfluidic channel including a floor and a ceiling. A channel height is defined as a distance between the floor and the ceiling. A channel height step can be in the floor, or ceiling, or both. The channel height downstream of the channel height step can be greater than the channel height upstream of the channel height step. An interior pillar can be positioned in the microfluidic channel extending from the floor to the ceiling. The interior pillar can include a widening portion at an upstream end of the interior pillar and a tapering portion at a downstream end of the interior pillar. The interior pillar can overlap the channel height step so that the interior pillar is partially upstream of the channel height step and partially downstream of the channel height step.

摘要： A method for manufacturing a battery. According to the method, a combination of binder resin composition and organic solvent causing low dissolution of polymer may be selected before manufacturing a battery. The binder resin composition, organic solvent or both may be applied to the manufacture of a battery to prevent degradation of adhesion of battery devices, and an increase in resistance caused by an increase in viscosity of an electrolyte.

摘要： A smear staining machine and a smearing control method and device thereof. The viscosity of the test sample is used for guiding the configuration of at least on smearing parameter. Since the viscosity of the test sample presents multiple influences of many effecting parameters, it is more suitable for presenting the characteristics of the test sample. Therefore, better smearing effect could be acquired by referring the viscosity of the test sample to get the smearing parameter.

摘要： Viscosity and other properties are determined at desired temperatures in drilling mud and other fluids by using a versatile cavitation device which, operating in the cavitation mode, mixes and heats the fluid to a specified temperature, and, operating in the shear mode, acts as a spindle for application of Couette principles to determine viscosity as a function of shear stress and shear rate. The invention obviates the practice of adjusting rheology of a drilling fluid by passing it through the drill bit. Drilling fluid may be managed by a “straight-through” method to the well, or by placing the cavitation device in a loop which isolates an aliquot of known volume and circulating the fluid through the loop including the cavitation device. A controller may be programmed to manage the viscosity and other properties at various temperatures by controlling the power input and angular rotation of the “spindle” (which has cavities on its cylindrical surface), and feeding viscosity-adjusting agents and other additives to the fluid. Data may be collected from the loop and used in the “straight-through” mode until it is determined that conditions require a new set of data, or the loop may be used continuously. The system may be used with a supplemental viscometer, density meter, and other instruments.
