  • Patent number: 11917717
    Abstract: The present invention discloses a wireless network detection apparatus. A storage circuit stores virtual wireless communication apparatus information. A wireless signal transmission circuit communicates using a wireless communication protocol. A processing circuit executes software or firmware executable commands to perform a wireless network detection method including the steps outlined below. Whether a wireless signal including non-predetermined electronic apparatus identification information being received is determined. When the wireless signal is received, an existence signal is broadcasted accordingly. A first-time pairing information that is transmitted from a non-predetermined electronic apparatus based on the existence signal is received to perform the first-time pairing and store the non-predetermined electronic apparatus identification information in the storage circuit.

  • Patent number: 11410465
    Abstract: The present disclosure discloses a face identification system that includes an image-retrieving circuit, an invisible light source and a processing circuit. The image-retrieving circuit includes light-sensing elements each including a plurality of visible light sensors and an invisible light sensor. The processing circuit executes software and firmware executable commands to execute a face identification method that includes the steps outlined below. An invisible light is emitted to an object to be identified by the invisible light source. A visible light sensed frame and an invisible light sensed frame are retrieved by using the visible and invisible light sensors. Determine whether a light reflection related parameter of the invisible light sensed frame is within a predetermined range is determined only according to the invisible light sensed frame. When the light reflection related parameter is within the predetermined range, the object to be identified is determined to be a real face.

  • Patent number: 11184587
    Abstract: The present disclosure discloses an image surveillance system that includes an image recording host and IP cameras. Each of the IP cameras includes a storage circuit that stores identification information including identification codes, a communication circuit that performs network communication and a processing circuit. The processing circuit executes software and firmware executable commands to execute an image surveillance system establishing method that includes the steps outlined below. The other IP cameras are identified according to the identification information by using the communication circuit to perform network connection thereto to form a local area network that only includes the IP cameras. Within the local area network, a connection path is set to connect the image recording host either indirectly through at least one of the other IP cameras or directly. An image stream is transmitted to the image recording host through the connection path by using the communication circuit.
