According to a first aspect of the present invention, there is provided a reconnaissance and communication assembly, adapted to be launched from a gun barrel into the air. The assembly comprises a carrier (with a cavity) and a payload (within the cavity). The payload is arranged to be controllably expelled from the carrier and once expelled from the carrier, the payload transmits a signal.

A wireless sound-emitting device includes a housing adapted to be coupled to a wall at a source of electric power, a loudspeaker positioned at a periphery of the housing, a control module outputting an electric audio signal to the at least one loudspeaker, and a wireless communications module in electrical communication with the control module. The loudspeaker emits acoustic signals in a direction parallel to the wall, when the housing is coupled to the wall, with the acoustic signals reflecting off the wall. The device may produce a sound masking noise or play a sound recorded on an internal memory. The device may include an electric plug or be adapted to replace an electric outlet faceplate. The device may have electric pass-through outlets and may be powered by the source of electric power. The device may be controlled remotely, for example via an Internet of Things (IoT) platform.

This disclosure describes systems, methods, and devices related to an invalid location measurement report (LMR) indication.

Aspects of the present invention disclose a method for identifying indications of an attack on a cellular network. The method includes one or more processors scanning a geographic area of a cellular network, wherein the geographic area includes a plurality of transceivers of the cellular network. The method further includes identifying a symptom that impacts a transceiver of the cellular network based at least in part on connectivity between a computing device and the plurality transceivers of the cellular network. The method further includes performing one or more assessments on the transceiver of the cellular network impacted by the symptom. The method further includes determining whether the symptom of the cellular network is associated with an attack on the cellular network based at least in part on the one or more assessments.

This application relates to a jamming signal generating apparatus. In one aspect, the jamming signal generating apparatus includes a signal analyzer configured to perform measurement and analysis of a radar reception signal, and a radio frequency (RF) source signal output device configured to receive the radar reception signal and to output a video signal by reflecting the measurement and the analysis.

A radio frequency (RF) jamming device includes a differential segmented aperture (DSA), a jammer source outputting a jamming signal at one or more frequencies or frequency bands to be jammed, and RF electronics that amplify and feed the jamming signal to the DSA so as to emit a jamming beam. The DSA includes an array of electrically conductive tapered projections, and the RF electronics comprise power splitters configured to split the jamming signal to aperture pixels of the DSA. The aperture pixels comprise pairs of electrically conductive tapered projections of the array of electrically conductive tapered projections. The RF electronics further comprise pixel power amplifiers, each connected to amplify the jamming signal fed to a single corresponding aperture pixel of the DSA. The RF jamming device may include a rifle-shaped housing, with the DSA mounted at a distal end of the barrel of the rifle-shaped housing.

A computer-implementable method employs network signal metadata to train a cognitive learning and inference system to produce an inferred function, wherein the metadata comprises a syntactic structure of at least one network communication protocol. The inferred function is used to map metadata of a detected network signal to a cognitive profile of a transmitter of the detected network signal. The mapping effects intelligent discrimination of the transmitter from at least one other transmitter through corroborative or negating evidentiary observation of properties associated with the metadata of the detected network signal. Information content in the network signal can be determined from the inferred function or the cognitive profile without demodulating the network signal.

An apparatus, system, and method for determining the presence of a mobile device located in a predetermined detection zone within a vehicle are disclosed. A detection module receives a communication signal, determines that the communication signal was transmitted by a mobile device located within a predetermined detection zone within a vehicle, and a control module transmits a control signal to the mobile device located within the predetermined detection zone. The system further includes a monitoring logic to monitor a functional system of the vehicle activating the transmission of the control signal by the control module when the monitored functional system is activated and the detection module determines that the communication signal was transmitted by the mobile device located within the predetermined detection zone.
