  • Patent number: 10755370
    Abstract: A method for monitoring mobile communication and generating alerts associated with targeted content. A monitored user's mobile communication device forwards an incoming or outgoing communication to a monitoring user's mobile communication device. The monitored user's or monitoring user's mobile communication device generates an alert if it is determined that the incoming or outgoing communication contains targeted content, and an alert is provided on the monitoring user's mobile communication device.

  • Patent number: 10735127
    Abstract: A wavelength division multiplexing (WDM)-based photonic radar architecture is disclosed. The WDM-based photonic radar incorporates a WDM photonic input of N component wavelengths modulated by an IF-LFM input signal and its 90-degree phased counterpart. The modulated WDM photonic signal is split one branch sent to a photodetector for generation of an RF outbound signal and transmission of the signal, which is reflected by a target and received as an RF echo signal after a time delay. The other branch has each component wavelength time-adjusted by a second time delay for each wavelength. The resulting time-delayed WDM photonic signal is modulated again based on the received RF echo signal and split into wavelength selective channels. Filters in each channel extract two adjacent photonic signals converted to RF output signals by photodetectors. RF filters select a single RF signal for processing based on the closest difference between the two time delays.

  • Patent number: 10649825
    Abstract: Systems, methods, and devices for managing predetermined functions on a mobile device within a moving vehicle, the mobile device having an operating system (OS) that includes an event API installed therein that is configured for two-way communication with an external control device, the control device being installed within the vehicle and further configured to communicate with a software application installed and running in memory resident on the mobile device. In response to initiation of a predetermined function on the mobile device, a notification message is transmitted by the event API to the control device. The control device then communicates with the software application to determine a desired action for the mobile device to take with respect to the predetermined function. The control device then instructs the mobile device on the action to take on the predetermined function by transmitting an action message to the event API.

  • Patent number: 10587359
    Abstract: A method and system of reliably detecting a reactive jamming attack and estimating the jammer's listening interval for exploitation by a communication system comprises channelizing one or more signals of interest (SOI), channelizing one or more signals of unknown origin (SUO), identifying frequency support patterns for the SOI and SUO using Bayes thresholds, comparing SOI and SUO detection map histories, and determining a percent match, where a match percentage above a specified minimum indicates a reactive attack. Edge detection can be used to enhance jammer support. Embodiments further detect reactive jammer adaptation to changes in the SOI's frequency support. Embodiments include detectors that are insensitive to jammer modulation and/or signal type. A jammer reaction delay and/or size and periodicity of receive window can be detected. Embodiments determine if a jammer is copying and retransmitting the SOI's waveform(s), and/or if the jammer is anticipatory.

  • Patent number: 10554623
    Abstract: Provided is an on-board communication system that can prevent a communication line from being occupied due to repetitive transmission of an unauthorized message. The on-board communication system includes a plurality of interconnected ECUs and a monitoring device including: a determination processing unit to determine whether a message is an authorized message; a discard processing unit to perform processing for discarding an unauthorized message; a storage unit to store the ID of the discarded message; and a notification processing unit to perform processing for outputting, an ACK signal indicating that the reception of the message is complete. The discard processing unit does not discard a message with the same ID as that stored in the storage unit. Each of the ECUs stores the ID added to a message subjected to the discard processing, and prohibits processing of a message with the same ID as that stored in the storage unit.
