  • Publication number: 20210188274
    Abstract: A method of controlling a vehicle includes sensing forward road conditions of a road surface of the road forwardly adjacent to the vehicle in a direction of vehicle travel. Responsive to the sensed road conditions, a forward road signal is generated. Adjacent-lane road conditions of an adjacent-lane road surface of the road lateral to the forward road surface are sensed. Responsive to the sensed adjacent-lane road conditions, an adjacent-lane road signal is generated. The forward road signal and the adjacent-lane road signal are received, and a recommended amelioration action is responsively determined. The recommended amelioration action is communicated to an operator of the vehicle, and/or an adjustment of at least one of a speed of the vehicle and a lateral position on the road of the vehicle is initiated, responsive to the recommended amelioration action. A system of controlling a vehicle is also provided.

  • Patent number: 6980151
    Abstract: A bi-static continuous wave radar system and related methods for detecting incoming threats from ballistic projectiles includes a remote source of RF illumination, and a local receiver installed in one or more target aircraft. A first receiving channel acquires direct path illumination from the source and provides a reference signal, and a second receiving channel acquires a scatter signal reflected by a projectile. A processor coupled to each receiver corrects scatter signal Doppler offset induced by relative source motion, isolates narrowband Doppler signals to derive signatures characteristic of the projectile, and by executing appropriate algorithms, compares the derived signatures to modeled signatures stored in memory. If the comparison yields a substantial similarity, the processor outputs a warning signal sufficient to initiate defensive countermeasures.

  • Patent number: 6894506
    Abstract: The spectral content of the interference response at a sensor array is taken into account and used to advantage in remote sensing or imaging an object or scene. The phase relationship between sensor elements is preserved, enabling the natural interference spectrum to be processed to generate a particular spatial response of the aggregate beam pattern. The method applies to diverse forms of broadband illumination or emissions including acoustic and electromagnetic radiation, and provides remote sensing capabilities linked to the sensor elements appropriate to the wavelength band of interest (e.g., acoustic, RF or optical). Since the relative geometry between the source, scene and sensing array is responsible for the generation of a desirable interference response, the source of illumination need only maintain a small degree of coherence (some finite correlation length), and can operate in a pulsed or continuous (CW) mode.

  • Patent number: 6657587
    Abstract: A tracking system uses a miniaturized geographic position determination and communications module, preferably in the form of a thin capsule, enabling the enclosure to be hidden in very small spaces, including personal concealment. Electronic circuitry and a thin, rechargeable battery are contained within the enclosure, the circuitry including a global positioning satellite receiver, a communications transceiver, and a controller. The controller causes the global positioning satellite receiver to receive and decode a signal relating to the geographic position of the module; cause the communications transmitter to communicate the geographic position information to a remote location; and disable the global positioning satellite receiver and communications transceiver when not in use so as to conserve power.
