A system is disclosed to control operation of a vehicle based on a blood alcohol content of a driver. A detector includes a sensor configured to measure an alcohol content of air in a predetermined three-dimensional zone within a vehicle. The three-dimensional zone is proximal to a driver seat side of the vehicle. The sensor is configured to measure the alcohol content of the air independent of interaction of a driver with the detector. The sensor is configured to produce an electrical signal representative of a blood alcohol content of the driver. A controller is electrically coupled to the detector. The controller is configured to determine a tamper event. Optionally, the controller is configured to detect a presence of the driver within the vehicle. A method for preventing operation of a vehicle by an intoxicated person also is disclosed.

A system may include a first radio comprising a first radio processor, a first radio modem, and a first radio transmitter configured to transmit non-hopping transmissions and hopping transmissions. The system may further include a second radio comprising a second radio processor, a second radio modem, and a second radio hopping receiver, wherein the second radio hopping receiver is a non-staring second radio receiver. The first radio may be configured to: receive a message and a destination for the message, the destination being the second radio; upon a determination that the destination has a non-staring receiver, store the message; determine a time interval start time for a cyclical hop pattern associated with the second radio; output the message from the memory to the first radio modem; output the message from the first radio modem to the first radio transmitter; and/or transmit the message to the second radio.

Disclosed herein is a method and system for detecting, monitoring and/or controlling one or more of mobile services for a mobile communication device (also referred to herein as a Controllable Mobile Device or CMD), and in particular, when the device is being used and the vehicle, operated by the user of the device, is moving. In addition, one aspect of the invention generally relates to a method and system for modifying a user's driving behaviors, in particular to a system and method for modifying a user's unsafe driving behaviors, e.g., using one or more services of a controllable mobile device while driving.

A high-power electromagnetic source for HPEM pulses in a desired radiation direction includes at least three antennas fixed in relation to one another for pulse components, wherein at least two groups of antennas with a respective main direction are present, and a control unit for the activation and phase position of the pulse components for the superimposition for the HPEM pulse, wherein the current radiation direction of said pulse is selectable in an angle range around the main direction. A vehicle with an HPEM source has the antennas mounted in a fixed position or a support for the antennas is pivotably mounted on the vehicle. In a method for emitting the HPEM pulse, all antennas are controlled in order to select the radiation direction in the angle range of less than 360°.

Disclosed is an anti-eavesdropping method for the Internet of Vehicles (IoV) based on intermittent cooperative jamming. The method comprises: on the premise of effectively preventing an illegitimate user V.sub.e from information eavesdropping, first establishing optimization problems for the purpose of minimizing an energy consumption of a cooperative jamming user V.sub.j; analyzing unique communication characteristics of the IoV based on the Wireless Access in Vehicular Environments (WAVE) protocol, to obtain time structures of physical-layer data packets in the IoV and physical-layer data packet duration; and calculating the shortest physical-layer data packet duration in the IoV; then solving an optimal cooperative jamming scheme for any available power range for the cooperative jamming user V.sub.j; and finally, conducting, by the cooperative jamming user V.sub.j, periodic repetition according to the solved optimal cooperative jamming schemes in a period of data transmission between legitimate users, until transmission between the legitimate users ends.

An unmanned aerial vehicle (UAV) includes a sensor configured to detect an indicator of a geo-fencing device; and a flight controller configured to generate one or more signals that cause the UAV to operate in accordance with a set of flight regulations that are generated based on the detected indicator of the geo-fencing device.

A system comprises a computer including a processor. The processor receives from each of a plurality of vehicles within a region, a respective plurality of messages and identifies for each of the plurality of vehicles, a respective communications discontinuity during which an expected message fails to be received from the respective vehicle. The processor determines, for each communications discontinuity, discontinuity edge locations at each of a beginning of the communications discontinuity and an end of the communications discontinuity. The processor further determines an interference node location based on the discontinuity edge locations.

Disclosed is a low-altitude unmanned aerial vehicle surveillance system. According to an embodiment, monitoring is performed using a balloon main body filled with gas and staying in the air; radar; camera units being provided outside the balloon main body, and including a camera taking an image of a subject; radio frequency detectors; and sound detectors and correspondingly, interceptor means is included. As interceptor means, a jammer, a jamming gun, and a spoofing device corresponding to jamming are disclosed.

An anti-drone integrated management device includes a drone detection unit that detects at least one drone invading a restricted area, a drone ID identification unit that requests drone unique information to the at least one detected drone, and receives drone unique information from the at least one detected drone, a drone ID identification information storage/management unit that stores and updates the drone unique information received by the drone ID identification unit, an anti-drone integrated controller that determines whether to neutralize the at least one detected drone based on the drone unique information stored in the drone ID identification information storage/management unit, and a drone neutralization unit that neutralizes the at least one detected drone under control of the anti-drone integrated controller.

Communication with a key fob of a vehicle can be controlled based on a key fob jamming condition. One or more sensors can be configured to detect the key fob jamming condition. In response to the key fob jamming condition being detected, a jamming device can be activated to cause one or more jamming signals to be emitted. The one or more jamming signals can prevent the key fob from receiving and responding to other signals.
