  • Publication number: 20190215695
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to detect attacks in V2X networks. An example apparatus includes a challenge handler to (a) transmit a first challenge packet to a first vehicle to request a transmission of a first response, (b) instruct a second challenge packet to be transmitted to a second vehicle to request a transmission of a second response, (c) increment a first counter when the first response is not obtained, (d) increment a second counter when the second response is not obtained, and (e) after repeating (a)-(d), determine that the first and second vehicles are phantom vehicles associated with an attacker with a half-duplex radio when at least one of the first or second counters satisfy a threshold, and a network interface to instruct a third vehicle associated with the V2X network to ignore future messages from the phantom vehicles based on the determination.

  • Patent number: 10026001
    Abstract: Systems and methods to generate maps or models of structures are disclosed. Features of the structure to be mapped may be determined for the purposes of generating the map or model based at least in part on images associated with the structure, sensor measurements associated with the structure, and phase data of communications signals that interact with the structure. The mapping or modeling processes may be performed at a mapping server that receives images, sensor data, and/or communications signal phase information from one or more user devices, such as mobile devices. The mapping servers may perform a simultaneous localization and mapping (SLAM) process and may enhance the generated maps using sensor and/or communications phase data to map one or more hidden features of the structure.

  • Patent number: 9287630
    Abstract: Embodiments of a folded meta-inspired antenna for dual-band operation and user equipment for dual-band operation in a wireless network are generally described herein. In some embodiments, the folded meta-inspired antenna may include first and second conductive layers disposed on opposite sides of a substrate to provide a wideband distributed structure comprising a plurality of high-Q resonances resulting from, at least in part, metamaterial-based loading. Conductive material on the first side of the substrate is arranged around a central longitudinal slot coupled with a plurality of perpendicular slots. For dual-band operation, the folded meta-inspired antenna may operate as a folded monopole at a higher frequency band and operate as a slot-type radiator at a lower frequency band. The plurality of resonances may cause the folded meta-inspired antenna to achieve broader bandwidth at both lower and higher frequency bands.

  • Patent number: 8706049
    Abstract: Disclosed are integration approaches for mm-wave planar phased array type architectures using multilayer substrate technologies. For instance, an apparatus may include a plurality of substrate layers, an integrated circuit, and a connector module. The plurality of substrate layers includes a first substrate layer having one or more phased array elements. The integrated circuit exchange one or more radio frequency (RF) signals (e.g., mm-wave signals) with the one or more phased array elements. The connector module exchange further signals with the integrated circuit that correspond to the one or more RF signals. For example, these further signals may be baseband or intermediate frequency (IF) signals.
