  • Patent number: 10923903
    Abstract: The invention provides a low phase surge protection device including a voltage converter, a low phase delay detector and an output control switch. The voltage converter receives an alternate current (AC) input voltage, and converts the AC input voltage into a direct current (DC) input voltage. The low phase delay detector receives the DC input voltage to be a power source, enables a phase detection scheme by detecting whether the AC input voltage is in a stable state, and generates an enable signal by detecting a phase of the AC input voltage after the phase detection scheme is enabled. The output control switch receives the AC input voltage, and determines whether to transmit the AC input voltage to be an output voltage according to the enable signal.

  • Publication number: 20180318148
    Abstract: A feminine care absorbent article (e.g., feminine care pad, sanitary napkin, incontinence article, pantiliner, etc.) that employs a color changing indicator graphic for signaling to the wearer an appropriate time to remove and/or replace the feminine care absorbent article following a liquid insult. This can be particularly useful in warm environments in which a wearer may secrete a significant amount of perspiration which may act as a carrier for microorganisms. In this manner, the wearer can wear the article without fear of a bacterial infection and/or the generation of an odor. After a time period of usage, the wearer can visually inspect the color of the color changing indicator graphic for an indication of whether it is time to remove and/or replace the feminine care absorbent article.

  • Publication number: 20150283852
    Abstract: A cushioning wheel member has an annular body, an axis and multiple cushioning spokes. The annular body has a through hole defined axially through the annular body. The axis is mounted axially and located centrally in the through hole of the annular body. The cushioning spokes are curved and resilient, are deformed to decentralize the axis with external force applied to the cushioning spokes and recover to centralize the axis with removal of the external force. Each cushioning spoke has two ends, and one end of the cushioning spoke is connected to an inner annular surface of the annular body and the other end is connected to the axis. The cushioning spokes are structurally simple and light and may be deformed when encountering external force or impact and therefore provide excellent press-engaging effect and cushioning effect when installed in an ink ribbon cassette and a light duty carrier.

  • Patent number: 8130232
    Abstract: A drawing control method, a drawing control apparatus, and a drawing control system for embedded system are provided. The present invention adopts an independent drawing control apparatus to control a drawing unit to draw a frame, and move the drawn frame to an external frame buffer in advance, and therefore the number of lines that can be drawn is not restricted by the capacity of the memory of the drawing unit. Further, the present invention employs a counter to accumulate a counting number upon each time completion of drawing frame or moving frame. Whenever the counting number is accumulated, the drawing unit is controlled to perform a next stage of frame drawing or frame moving. In this concern, the present invention eliminates the time for external accessing, and thus achieving parallel processing, and instant displaying.
