  • Publication number: 20250004978
    Abstract: A device includes a signal-edge detector, an anomaly detector and a reset-interrupt generator. The signal-edge detector outputs a timing-start signal when detecting that a logic level of an SDA signal from an SDA line of an I2C bus changes from logical high to logical low, and outputs a timing-reset signal when detecting that the logic level changes from logical low to logical high. Upon receiving the timing-start signal, the anomaly detector starts to time a timing duration, and outputs an error signal when the timing duration reaches a preset time duration. Upon receiving the timing-reset signal, the anomaly detector resets the timing duration to zero. In response to receipt of the error signal, the reset-interrupt generator outputs an interrupt signal to a processor for removing an abnormal state, or outputs a pin-reset signal to an optical module to reset a pin connected to the SDA line.

  • Publication number: 20130256932
    Abstract: A method for preparing a hemisphere-shaped dosage form containing drug. A high molecular weight solution containing the drug is prepared, and the solution is then dropped onto a base material. The interface phenomenon between the solution and different base materials causes the solution to form a hemisphere-shaped liquid drop dosage. After solidifying by cross-link or evaporation, a hemisphere-shaped dosage form containing drug is obtained. The advantages of the preparation method are a simple and fast process, and simple operation. Applications of the preparation method to prepare a hemisphere-shaped dosage form containing drug are also provide.

  • Patent number: 7969563
    Abstract: A lens measuring device and method applied therein. The lens measuring device includes a light source, a first polarizer, a second polarizer, and an image analysis module. The method includes enabling the light source to orderly pass through the first polarizer, a lens to be measured, and the second polarizer to generate a light beam to be measured, and then enabling the image analysis module to analyze image-related information of the light beam to be measured, consequently deducing the structural center and energy distribution of the lens to be measured, and then further analyzing errors in polarity and skewness of the lens to be measured. By applying a common light source, the method is spared complicated correction that is otherwise required when a conventional collimating laser light source is applied, and the method can also easily and simultaneously test a plurality of lenses to be measured.
