A near field communication system can include a near field generator configured to generate a near field detectable information signal. The near field generator and supporting circuitry also produces incidental electromagnetic radiation. A masking signal transmitter is used with the near field generator and radiates a masking electromagnetic signal. The masking electromagnetic signal may substantially mask the incidental electromagnetic radiation.

Systems, apparatuses, and methods are described for a privacy blocking device configured to prevent receipt, by a listening device, of video and/or audio data until a trigger occurs. A blocker may be configured to prevent receipt of video and/or audio data by one or more microphones and/or one or more cameras of a listening device. The blocker may use the one or more microphones, the one or more cameras, and/or one or more second microphones and/or one or more second cameras to monitor for a trigger. The blocker may process the data. Upon detecting the trigger, the blocker may transmit data to the listening device. For example, the blocker may transmit all or a part of a spoken phrase to the listening device.

An Unmanned Aerial Vehicle is disclosed. The Unmanned Aerial Vehicle includes a body, rotors attached to the body, one or more sensors, and an electromagnetic pulse transmitter. The electromagnetic pulse transmitter is configured to transmit an EMP and the Unmanned Aerial Vehicle is configured to track a target Unmanned Aerial Vehicle using the one or more sensors and direct the electromagnetic pulse transmitter at the target Unmanned Aerial Vehicle to disrupt the target Unmanned Aerial Vehicle.

A system, method and computer program product for controlled drone descent, and deactivation, including a drone deactivation system; and a location system. The drone deactivation system calculates positioning, signal reception, signal strength, and signal identification parameters of a target drone from the location system, and determines an attack method based on the calculated parameters. The drone deactivation system employs the determined attack method against the target drone for forcing at least one of controlled drone descent, and deactivation of the target drone.

A method is disclosed that includes obtaining one or more pieces of threat information indicative of a data set enabling positioning based on radio signals sent by a respective radio node. The data set is further indicative of one or more parameters based on which said positioning is performed and/or controlled and which is considered to be at least partially unexpected. The method also includes utilizing the one or more pieces of threat information in a positioning. In order to obtain the one or more pieces of threat information, the method includes at least one of: obtaining the one or more pieces of threat information by using an application programming interface; or obtaining the one or more pieces of spoofing information by using a push method. A corresponding apparatus, computer-readable storage medium and system are also disclosed.

Jamming systems uses wireless signals (e.g., radio waves) to deliberately prevent a target from accurately receiving desired wireless signals. The examples herein disclose an anti-jamming system that mitigates an effect that jamming signals have on a radio receiver. To do so, the anti-jamming system generates a plasma shield in a region of space between the target and the jamming system. Plasma is opaque to electromagnetic energy meaning that radio signals, lasers, microwave energy, and the like are unable to pass through the plasma, and instead, are absorbed by the plasma. As such, the jamming signals emitted by the jamming system are absorbed by the plasma shield and do not interfere with the target's radio receiver.

A system for near field communications is provided. The system can include a near field generator configured to generate a near field detectable signal comprising information. The system can include a near field detector configured to receive the near field detectable signal and output the information. The system can include an Electro-Magnetic (EM) shield surrounding the near field generator to block EM radio frequency (RF) signals in the vicinity of the near field generator from interfering with operations of the near field generator. The EM shield does not prevent communication of the near field detectable signal between the near field generator and the near field detector. The EM shield can be configured to reduce magnetic field loss from eddy currents in the EM shield as the near field detectable signal passes through the EM shield.

An airborne redirection unit (ARU), for deflecting an RF energy beam, the ARU comprising: A canopy comprising a surface for slowing the rate of descent, A beam director supported at the canopy, the ARU being configured to focus the RF energy beam.
