Embodiments of this disclosure relate to electronic information, and disclose a smart refrigerator based on big data analysis of a server, including a refrigerator body, a collector, and a communication circuit. The collector is disposed in the refrigerator body and is used to collect human body health parameter information. The communication circuit is disposed in the refrigerator body and is connected to the collector, and is used to: upload human body health parameter information to a server, obtain a diet solution that is returned by the server after the server performs big data analysis on the human body health parameter information, and push the diet solution. This disclosure further discloses a health management method based on a smart refrigerator and a health management system. The smart refrigerator based on big data analysis of a server, the health management method based on a smart refrigerator, and the health management system that are provided in the embodiments of this disclosure can help a user properly plan healthy diets.

A novel piezo-driven cell injection system with force feedback overcomes the unsatisfied force interaction between the pipette needle and embryos in conventional position control. By integrating semiconductor strain-gage sensors for detecting the cell penetration force and the micropipette relative position in real time, the developed cell microinjection system features high operation speed, confident success rate, and high survival rate. The effectiveness of the developed cell injection system is experimentally verified by penetrating zebrafish embryos. The injection of 100 embryos are conducted with separate position control and force control. Results indicate that the force control enables a survival rate of 86%, which is higher than the survival rate of 82% produced by the position control in the same control environment. The experimental results quantitatively demonstrate the superiority of force control over conventional position control for the first time.

Various embodiments illustrated herein disclose a method for monitoring disinfection of a device. The method includes receiving sensor data from a plurality of sensors positioned at a respective plurality of surfaces of the device. The sensor data indicates that a disinfecting agent is applied on one or more surfaces of the plurality of surfaces of the device. The method further includes determining at least one exposure characteristic based on the sensor data. The at least one exposure characteristic is associated with disinfection of the one or more surfaces of the device by the disinfecting agent. The method further includes comparing the at least one exposure characteristic to a threshold parameter associated with the at least one exposure characteristic. In response to the comparison, the method further includes generating a notification indicating that the one or more surfaces of the device are disinfected.

Systems and methods are disclosed herein that include providing an active torsion damper control system that includes a rotatable component (206) and a rotatable measurement interface (302) disposed on the rotatable component, the rotatable measurement interface having at least one torsional strain gauge configured to measure a strain of the rotatable component, a torque management (306) computer configured to determine a resonant frequency of the rotatable component and a corrective torque needed to be applied to the rotatable component to excite the resonant frequency as a function of the measured strain, and a correction motor (308) configured to impart the corrective torque on the rotatable component.
