  • Patent number: 11374529
    Abstract: The present invention provides a fan speed control method for avoiding inaccurate control caused by sudden changes in a power supply output state, including the steps of: acquiring an output current value of a power supply device; and then, determining a change of the output current value in a sampling timeframe, if a slope representing the change is positive, controlling the control signal generating unit to gradually replace the fan control signal currently output to the fan with another fan control signal on the basis of a first latency, and if the slope representing the change is negative, controlling the control signal generating unit to gradually replace the fan control signal currently output to the fan with another fan control signal on the basis of a second latency. The first latency and the second latency are determined by the output current value, respectively.

  • Publication number: 20220192376
    Abstract: A slide rail assembly and a slide rail kit are provided. The slide rail assembly includes a first rail, a second rail, a blocking member, and an operating member. The blocking member is movably mounted on the second rail. When the second rail is positioned at an extending position relative to the first rail, a blocking feature of the first rail blocks the blocking member at a first state, so as to prevent the second rail from being moved from the extending position in a retracting direction. The operating member is operated to be positioned at a position that moves the blocking member from the first state to a second state, such that the blocking feature is unable to block the blocking member at the second state. The operating member is engaged with the predetermined portion of the second rail to be retained at the position.
