  • Publication number: 20260041625
    Abstract: Disclosed is the use of an Ixeris chinensis extract for delaying UV-induced skin photoaging, a method for preparing Ixeris chinensis extract, and an Ixeris chinensis extract. The preparation method involves preparing Ixeris chinensis coarse material and performing emulsification microwave extraction. The resulting Ixeris chinensis extract has a total flavonoid content of 30000-37000 ppm as measured by an aluminum chloride flavonoid method. This extract can absorb UV light, promote skin fibroblast activity, protect cells from UVA-induced oxidative and DNA damage, and reduce melanin production in cells, thereby preventing or delaying the UV-induced photoaging.

  • Patent number: 12429592
    Abstract: A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.

  • Patent number: 12177233
    Abstract: The present invention provides an information security incident diagnosis system for assisting in detecting whether a target network system has been hacked. First, a plurality of activities records of one or more computing devices in a target network system are collected. Then, a discrete space metric tree is generated according to the plurality of activities records, and a clustering operation is performed on the discrete space metric tree to generate one or more event clusters associated with one or more suspicious event categories. Each event cluster may form a guide tree corresponding to the event cluster through single linkage clustering analysis to indicate a merging order from high to low similarity. The merging order is used for recursively performing a graph generating operation to convert a plurality of activities records corresponding to the one or more event clusters into a hierarchical directed acyclic graph (HDAG).

  • Patent number: 12086241
    Abstract: The present invention provides an event visualization device configured to generate one or more directed acyclic graphs (DAGs) that can be used as a basis for diagnosing whether a target network system has been hacked according to a plurality of activities records. The plurality of activities records pertain to an event cluster associated with a suspicious event category. The event visualization device performs a graph generating operation on the plurality of activities records in a recursive manner to generate a hierarchical directed acyclic graph (HDAG). The graph generating operation includes: interpreting an activities record into a target DAG, and performing a hierarchical partial order alignment (HPOA) operation on the target DAG and a reference DAG to obtain a merging condition of each node; and merging the target DAG and the reference DAG into the HDAG according to the merging condition.
