  • Publication number: 20250244252
    Abstract: The present disclosure discloses an inspection device and an inspection method. The inspection device includes a first light source, a second light source, a light source controller and a sensor. The light source controller is configured to enable the first light source to irradiate an object under inspection in a first period of an inspection phase, and to enable the second light source to irradiate the object under inspection in a second period of the inspection phase. The sensor continuously senses the reflected light of the object under inspection in an exposure period of the inspection phase so as to obtain image data of the object under inspection. The exposure period includes the first period and the second period.

  • Patent number: 12375948
    Abstract: Examples provide new roaming test systems for network deployments that can be implemented remotely using a single physical AP. Examples achieve this elegant system by emulating a physical network deployment using a group of VAPs provisioned on the single physical AP (a VAP may refer to a logical or a virtual AP instance on a physical AP). Each VAP of CAP group may be configured to represent a physical AP of the physical network deployment (such a network deployment may be a prospective deployment or, an actual/set-up deployment). Examples can simulate/emulate a wireless client physically moving between physical APs of the network deployment by varying transmission power associated with each VAP as a function of time in a manner that mirrors how a wireless client would perceive transmission power varying for physical APs of the network deployment (represented by the VAPs) as the wireless client moves across the geographical site of the network deployment.
