  • Publication number: 20240136760
    Abstract: A waterproof electrical connector includes a connector body and a waterproof cap. The connector body includes a mating island surrounded by a ring groove. The mating island defines a mating face and plural passageways. The passageways receive conductive terminals and penetrate through the mating face. A soft cushion is set inside the waterproof cap. The connector body includes a collar portion. The collar portion is higher than the mating face and forms an entrance cavity around the ring groove. When the cap covers the connector body, the soft cushion penetrates into the entrance cavity to press and seal the mating face.

  • Patent number: 7881515
    Abstract: An automated cephalogram image analysis method is disclosed. In this method, a step is first performed for building a reference database in which a set of tracing feature curve models respectively representing a set of reference cephalometric patterns are established based on a set of tracing records. Then, a step of pattern comparison and analysis is performed. In this step, at least one cephalogram is first input, and then a step is performed for comparing the image of the cephalogram with the tracing feature curve models, thereby selecting at least one cephalometric pattern and at least one feature curve model belonging to the cephalometric pattern from the reference cephalometric patterns and the tracing feature curve models. Thereafter, the feature curve model is fitted to the image of the cephalogram so as to obtain at least one tracing of the at least one cephalogram.
