  • Publication number: 20180262327
    Abstract: A method for operation of a communication network reduces leakage of data to an adversary that can observe signals transmitted through the communication network. The method includes generating a ranking to order operation of a plurality of nodes that exchange data in a group cryptographic key exchange process based on a leakage map of the nodes. The ranking minimizes leakage of data through a shared communication medium during the group cryptographic key exchange process. The method includes transmitting the ranking to the plurality of nodes through the shared communication medium, and performing, with the plurality of nodes, the group cryptographic key exchange process in an order of operation specified in the ranking to enable the plurality of nodes to exchange a shared cryptographic key through the shared communication medium while minimizing leakage of data.

  • Patent number: 10035023
    Abstract: A method of utilizing automatic external defibrillators (AEDs) includes receiving a cardiac emergency alert including a position of the alert at an AED deployment coordinating system connected to an AED network. The deployment coordinating system communicates AED network interface devices and client devices via the AED network and identifies for deployment to the position of the cardiac emergency. The cardiac emergency alert is transmitted to the AED network interface devices associated with the identified AEDs. Information pertaining to the cardiac emergency alert is then displayed on a display of the AED network interface device including the position of the cardiac emergency.

  • Publication number: 20170364766
    Abstract: A method is disclosed of discriminating detected objects in an area with a vision apparatus. The method includes generating image data of a portion of the area using an imaging device of the object detection device, and processing the image data to classify the image data as an imaged scene type selected from a plurality of scene types stored as scene type data in the memory. The method further includes processing the image data using the object identification data to generate object detection data for each object of the plurality of objects located in the portion of the area, each object detection data having a corresponding scene type of the plurality of scene types obtained from the object identification data, and generating user a sensible output only for the object detection data having a corresponding scene type that is the same as the imaged scene type.

  • Patent number: 9668073
    Abstract: A method of operating an audio monitoring system includes generating with a sound sensor audio data corresponding to a sound event generated by an object in a scene around the sound sensor, identifying with a processor a type and action of the object in the scene that generated the sound with reference to the audio data, generating with the processor a timestamp corresponding to a time of the detection of the sound event, and updating a scene state model corresponding to sound events generated by a plurality of objects in the scene with reference to the identified type of object, action taken by the object, and the timestamp. The method further includes identifying a sound event in the scene with reference to the scene state model and a predetermined scene grammar stored in a memory, and generating with the processor an output corresponding to the sound event.
