  • Publication number: 20230083055
    Abstract: A driving circuit for driving a light source and a projection device are provided. The driving circuit includes a power converter, a detection circuit, and a control circuit. The power converter provides a driving power to the light source. The detection circuit provides a feedback signal according to a current value of the light source. The control circuit receives an operation command and the feedback signal. The control circuit determines whether the driving circuit enters a light-load state according to at least one of the operation command and the feedback signal. When the driving circuit is determined to enter the light-load state, the control circuit controls the power converter to decrease a current value of the driving power and controls the power converter to increase a switching frequency of the driving power. The driving circuit and the projection device may prevent the light source from flickering under the light-load state.

  • Publication number: 20210368692
    Abstract: A system for suspending and self-balancing containers of crops includes first and second support rods and two cables tensioned between them. The two cables are connected to each other to form a closed-loop cable system. Support members for supporting the closed-loop cable system are coupled to the first and second support rods. Each support member includes a first arc-shaped surface. The closed-loop cable system is tensioned against the first arc-shaped surfaces. When the closed-loop cable system is under stress, it can facilitate the self-adjustment of the height of the cables by a relative sliding motion between the closed-loop cable system and the first arc-shaped surfaces.

    Abstract: The present disclosure is related to a method, a system, a non-transitory computer-readable medium and a computer program product for calibrating time of a physiological data. The method includes providing a physiological monitoring device for storing a physiological data with a first measurement time, and the physiological monitoring device has a first counting time. A wireless communication channel is established between the physiological monitoring device and a time calibration device having a second counting time. The first counting time and the second counting time are compared to obtain a counting time deviation value, and the counting time deviation value is compared with a predetermined time deviation value. If the counting time deviation value exceeds the predetermined time deviation value, the first measurement time and the counting time deviation value are computed to obtain a calibrated measurement time of the physiological data.
