  • Publication number: 20240426782
    Abstract: The ultrasonic quality sensor includes a probe assembly, a control module, an ultrasonic probe base, a probe filter, a temperature sensor, and a probe top cover; The probe assembly consists of a transmitting and a receiving transducer to form a face-to-face layout and the ultrasonic flight distance h, h?(V0*V50)*T0/(V50?V0), where T0 is the pulse width, V0 is the ultrasonic speed at 4° C. in water, V50 is the ultrasonic speed at 50% urea and 70° C. Sampling timing tb?[t0, t0+C], where C=(N+1)*T0, t0=h/V0, N is the number of ultrasonic actuating pulses. tr and td are first rising edge trigger timing and first falling edge trigger timing; As long as td?tr exceeds a certain percentage of T0, the chip can catch timing tf after tb of wave rising edge crosses zero. The cylindrical ring has small holes to carry away bubbles during high-temperature stages.

  • Patent number: 11143622
    Abstract: Provided is an ultrasonic liquid concentration detecting device including a vibrating structure, a bubble removing structure, and an ultrasonic detecting main body. The vibrating structure is disposed at the bottom of the ultrasonic detecting main body and is configured to buffer a shock received by the ultrasonic detecting main body. The bubble removing structure is disposed on the ultrasonic detecting main body and is configured to accelerate the flow rate of a liquid. The ultrasonic detecting main body is configured to detect a concentration of the liquid. Further provided are a bubble removing device and a vibrating structure for an ultrasonic liquid concentration detecting device.

  • Patent number: 10836030
    Abstract: A bionic robot and a spine apparatus thereof. Magnetorheological fluids are filled in the cavity, the first tube and the second tube to actuate the first end of the piston rod, so that the piston rod is actuated to move along the axial direction of the cavity. The excitation coil is wound around the first tube. When the controller provides a variable current for the excitation coil, the excitation coil produces a variable magnetic field at the first tube, thereby causing a magnetorheological effect that the magnetorheological fluid is in low liquidity and high viscosity. Then, the transmission speed of the piston rod is changed, which is presented as a damping characteristic, reducing the pause and transition in the spine apparatus, and improving the flexibility and the bionic performance of the robot.
