  • Patent number: 6259374
    Abstract: Systems and methods are described for passive pavement-mounted acoustical alert of the occupants of a vehicle. A method of notifying a vehicle occupant includes providing a driving medium upon which a vehicle is to be driven; and texturing a portion of the driving medium such that the textured portion interacts with the vehicle to produce audible signals, the textured portion pattern such that a linguistic message is encoded into the audible signals. The systems and methods provide advantages because information can be conveyed to the occupants of the vehicle based on the location of the vehicle relative to the textured surface.

  • Patent number: 6100797
    Abstract: To assure that the safety device is triggered at the right time in the event of a lateral collision of the vehicle with a curb, a first comparing device (1) compares a rotation rate (.omega.x) measured relative to the longitudinal axis of the vehicle, or a variable derived from this rotation rate, with a rotation rate threshold value. A second comparing device (2) compares an acceleration (ay), measured in the direction of the transverse axis of the vehicle, with a lateral acceleration threshold value. If both threshold comparing device (1, 2) simultaneously signal that their threshold values are being exceeded, a trigger signal (as1) for the safety device is output.

  • Patent number: 5701122
    Abstract: An electronic curb feeler system uses two pairs of optical sensor units to detect an object located near the front end of a vehicle during parking. One pair of optical sensor units detects an object directly in front of a left portion of the front end of the vehicle while another pair of optical sensors detects an object directly in front of a right portion of the front end of the vehicle. By supplying the operator of the vehicle with the location of the object as well as the exact distance the object is from the front end of the vehicle the operator can avoid hitting the object while parking very close to the object.

  • Patent number: 5682136
    Abstract: A system which provides an alarm indicative of a presence of an obstacle in a vicinity of a vehicle. The system operates by electromagnetic detection, and generates an oscillating radiofrequency signal. A transmitter transmits the generated oscillated radiofrequency signal to create, all around the transmitter, an electromagnetic radiofrequency near field. A receiver receives the electromagnetic radiofrequency near field. A detector is connected to the receiver and detects a perturbation resulting in a reduction of an oscillation amplitude of the electromagnetic radiofrequency near field, and an indicator indicates the detected perturbation of the received electromagnetic radiofrequency near field. Based on this operation, an obstacle in a vicinity of the vehicle can be detected.

  • Patent number: 5629681
    Abstract: The displacement sensor of this invention comprises a tube combined with a sonic transmitter and receiver. The tube acts as a waveguide for the sonic waves and a processor determines whether the tube has changed in length or has been constricted which, in either case, changes the pattern of sonic waves traveling from the transmitter to the receiver. In some applications, the transmitter and receiver are at different ends of the tube. In these cases, the attenuation in sound energy reaching the receiver, caused by the tube being squeezed at at least one point, is measured and the amount of cross action area reduction is determined. In other applications, the transmitter and receiver are at the same end of the tube and, in some of these cases, the transmitter and receiver are the same transducer.
