A navigation system includes a communication port in a vehicle, a hand held portable unit, and a wireless communication between the portable unit and the communication port when the portable unit is in the vehicle. The portable unit has a position locator and is capable of establishing a geographical position of the portable unit. The portable unit is removable from the vehicle by an occupant of the vehicle. An information display may be disposed on, at or within an interior rearview mirror assembly of the vehicle, and may display navigational information for viewing by a driver of the vehicle. The navigational information may be derived from the wireless communication between the portable unit and the communication port. |

A vehicle-based navigation system is described including a position locator that establishes the geographic position of the vehicle and a map database located external to and remote from the vehicle. The system determines at least one of a vehicle parameter and a personal parameter, and transfers data from the remote map database to the vehicle and displays the data in the vehicle at a resolution that is a function of at least one of a vehicle parameter and a personal parameter. |

A danger proximity warning system and method are disclosed that utilize ultra wideband (UWB) technology to effectively warn a person when there is a potentially dangerous situation in their vicinity. In one embodiment, the danger proximity warning system includes a transmitting UWB radio coupled to a first object and a receiving impulse radio unit coupled to a second object. The transmitting impulse radio unit operates to transmit an UWB signal towards the second object when the first object is a predetermined distance away. Upon receiving the UWB signal, the receiving UWB radio makes sure a person associated with the second object is informed about the potentially dangerous situation. Several embodiments of the danger proximity warning system and method are disclosed all of which operate to warn a person when there is a potentially dangerous situation in their vicinity. |

A first vehicle includes a first device for receiving global positioning system (GPS) signals, generating at least one of a first time, position and velocity signal based on the received GPS signals, generating at least one of a second time, position and velocity signal based upon the motion of the first vehicle, comparing the first and second signals, generating a corrected first vehicle signal, and transmitting the corrected first vehicle signal. A second vehicle includes a second device for receiving GPS signals, generating at least one of a third time, position and velocity based on the received GPS signals, generating at least one of a fourth time, position and velocity based on the motion of the second vehicle, comparing the third and fourth signals, generating a corrected second vehicle signal, receiving the corrected first signal, and calculating from the corrected first and second vehicle signals the likelihood that the positions of the first and second vehicles will coincide at some time. |

A method and system for automatically activating a train warning device that uses a positioning system such as a global positioning system (GPS) receiver or an inertial navigation system (INS) to determine the train's position. The system further includes a database containing locations of grade crossings and other locations at which a train is required to give a warning signal and what regulations govern activation of the warning device at such locations. |

A traffic warning system which alerts approaching vehicle traffic to the presence of a pedestrian in a crosswalk. The system includes a plurality of surface mounted lights partially embedded in and placed across a roadway. The lights are activated by the pedestrian, either by manual switch or by a sensor, before he enters the crosswalk. Once activated, the flashing lights warn drivers of approaching vehicles that the pedestrian may have entered the crosswalk, and that caution should be exercised. |

A warning light having a switching system where the behavior of a warning light can be altered by actuation of a switching mechanism by rotary actuation of a connector plug. A rotary pin base located adjacent to a connector plug receptor port is rotated by an engaging connector plug to rotationally position pins in the rotary pin base for the purpose of contacting stationary switch pins in a stationary pin base to provide electrical current of different natures and attributes to a warning lamp. |

A railroad crossing gate arm electrical lamp system provides two flashing lamps and one continuously operated lamp. Each of the lamps has an internal electrical circuit with the internal electrical circuits being identical for each lamp. This permits the lamps to be interchanged in position with the lamp positions determining the function of the lamp. Each lamp electricl circuit has a three-wire input connection and a three-wire output connection. There are identical and reversible three-wire cables connecting the first flashing lamp with the second flashing lamp and the second flashing lamp with the continuously operated lamp. The input for the first flashing lamp includes two power supply terminals and a third common terminal. The lamps are connected in series across the power supply and a relay alternately shunts the lamps to obtain flashing of two of the lamps. The third lamp is connected across the power supply for steady light. |

A safety transmitting device for warning a motor vehicle at a railroad crossing of the approach of a train includes a tuning fork mechanically communicating with the tracks, wherein the vibrations of the tracks causes the fork to transmit sound waves. The sound waves are converted to the electro-magnetic waves by a transmitter unit. The fork and transmitter unit are positioned at a predetermined distance from the crossing. The electromagnetic waves are picked up by a receiver unit in the motor vehicle and converted to the electrical energy which causes activation of a sound device and flashing light unit in the interior of the motor vehicle as well as activation of an electrical pump in the brake line assembly of the vehicle which causes automatic slow application of the brakes. |
