    Abstract: A zero velocity bead dispenser is provided for a paint striping vehicle. The dispenser includes an electric motor which rotates a pair of rollers. A bead gun directs reflective particles into the nip point between the rollers, which discharge the particles or beads with a rearward velocity substantially matching the forward velocity of the vehicle. Therefore, the beads are discharged into the wet paint on the road with a net zero velocity so as to minimize or eliminate rolling of the beads in the paint, thereby maximizing the reflective properties of the beads. A speed sensor continuously monitors the vehicle speed and automatically adjusts the motor speed, and thus the roller speed, so as to maintain the relative zero velocity of the discharged beads.

    Abstract: A recessed snowplowable reflective pavement marker is mounted in a shallow elongated groove in a highway surface to expose the marker to headlights of oncoming motor vehicles. The marker has a plastic housing with a pocket for holding the reflector and two sidewalls that support positioning tabs to overlie the uncut pavement. These tabs maintain markers at a fixed depth below the pavement. Two other upstanding sidewalls extend laterally in the groove and terminate at the lower edge of the reflective area of the reflector. These sidewalls prevent adhesive from entering the reflector pocket. The function of the positioning tabs and lateral sidewalls plus the requirement that headlights need only illuminate this reflective area and not the reflector's non reflective base serve to reduce groove depth by 50% less than prior art. This lightweight plastic housing and shallower groove reduce installation costs and enhance marker safety and performance.

  • Publication number: 20080101859
    Abstract: A warning apparatus is provided, whose main body includes a monolithically formed transparent tempered material with a thickness. The top of the main body includes at least two injections units. The injection units are upward bumps. The injection units are less than 10 mm in height. The curvature on the surface of injection unit bumps changes at different height of the bumps. The bottom of the main body includes at least two reflection units. The reflection units are downward bumps. The bottom of the main body also includes a reflective layer attached to the outer surface of the reflection units so that the light entering the main body can be reflected by the reflective layer to provide warning. The durable, low-height injection unit bumps will minimize the impact on the driving safety when the tires run over, while providing effective visual warning.

  • Patent number: 7333631
    Abstract: A landmark used to effectively determine the location of an autonomous vehicle, and a self-localization apparatus and method using the landmark are provided. In the self-localization method, first, first and second outer line information and shape information are extracted from a landmark image received from a camera. Next, a projective invariant is calculated from the shape information and stored in a hash table. Thereafter, the calculated projective invariant is compared with reference projective invariants for a plurality of landmarks stored in a predetermined data storage area in the form of a hash table, thereby determining which landmark corresponds to the landmark image. Then, information on the distance and orientation of the determined landmark with respect to the autonomous vehicle is analyzed in response to the first and second outer line information.

  • Patent number: 7140803
    Abstract: A system and process for detecting a traffic lane boundary before it is potentially violated by a moving vehicle traveling in the lane. Passive RF tags or labels are embedded in a paint stripe running along pavement. A sensor in the vehicle emits an RF signal at a frequency to which the tags or labels are responsive. When the emitted signal is incident on a tag or label with strength indicative of straying of the vehicle from the lane toward incipient violation of the lane boundary defined by the stripe, the tag or label issues a return signal that is received by the sensor for on-board signaling of the potential violation to alter the driver so that corrective action can be taken.

  • Patent number: 7077600
    Abstract: A roadway marking system, comprising a roadway marking tape and a plurality of spaced reflective roadway markers having a white reflective front surface, a red reflective rear surface and a elevated crest, is applied to an upper surface of a roadway. The roadway marking tape has a lower surface with an expandable adhesive material and a plurality of contoured roadway spikes, projecting from the reflective roadway markers which are exposed from the lower surface through the adhesive material. When downward pressure is applied to the upper surface of the roadway marking tape and the elevated crest of the reflective roadway markers, the roadway marking system becomes permanently attached to the upper surface of the roadway with the adhesive material providing a permanent adhesive seal between the marking tape and the roadway surface. Once attached to the roadway, the roadway marking system provides an audible, tactile and visual warning to a driver traveling on the roadway over the roadway marking system.
