  • Publication number: 20250060450
    Abstract: The present disclosure describes a system and a method for object detection and counter measures. A signal reflected by an object in an environment is conditioned to improve various parameters such as signal to noise ratio, spectral resolution, color mapping, or the like. A determination whether the object is unmanned aerial vehicle is based on an output of a trained AI model. The trained AI model classifies the detected object into a category based on the conditioned signal. Additionally, a jammer and spoofer are orchestrated based on determination that the object is an unmanned aerial vehicle. A control of the object is achieved based on the orchestration to perform counter measures such as jamming and spoofing.

  • Patent number: 9219616
    Abstract: In one embodiment, a network device, such as a router, receives a frame containing a message from a first terminal unit. The network device modifies the received frame by replacing an original value of an originator identifier field in the frame with a new value that is locally unique on a particular data link. The network device than forwards the modified frame to a selected second terminal unit selected from a plurality of terminal units.

  • Patent number: 8891538
    Abstract: In one embodiment, a router maintains a communication session between a local terminal unit and a remote terminal unit, the local terminal unit interconnected to the router over a local serial data link, and the remote terminal unit interconnected to the router over an Internet Protocol (IP) session via a remote router and a corresponding remote serial data link. The router may then monitor a state of the local serial data link, and communicates this state with the remote router over the IP session, as well as a remote state of the remote serial data link. The router may then correspondingly control the state of the local serial data link to match the remote state of the remote serial data link.

  • Patent number: 6609910
    Abstract: A flossing tip for a power dental flossing device. The tip is elongated and includes a base portion, a central portion having a generally rectangular cross-section, and an enlarged end portion including a disk shape. The tip is compressible. The base portion supports the tip when the tip is coupled to the dental flossing device. The central portion couples the base portion to the end portion. The end portion is inserted between a pair of adjacent teeth of a user, and helps guide and orient the tip between the adjacent teeth. When in use, the rectangular cross-section of the tip provides multiple points of contact against a tooth for cleaning, and also helps maintain the tip in proper orientation with respect to the teeth. The enlarged end portion assists in positioning the tip, provides additional cleaning edges, and helps prevent trauma to the gums.
