  • Patent number: 10210759
    Abstract: A method for enabling an interoperable vehicle safety network using wireless communication makes use of multiple traffic-monitoring devices that wirelessly communicate with each other. Each traffic-monitoring device records time-dependent inertial (TDI) data to determine a current trajectory. The TDI data includes current location, current velocity, and current orientation information. This information is used to monitor the current trajectory of each traffic-monitoring device and to predict the future position of each traffic-monitoring device. The trajectory of traffic-monitoring devices that are nearby to each other are analyzed to determine if there is a possibility of the devices colliding. If there is a possibility of the traffic-monitoring devices colliding, an alert is generated to prevent the collision. Additionally, the traffic-monitoring device sends out an emergency message if an accident actually occurs.

  • Patent number: 8347894
    Abstract: A fusion comb is a single comb which houses two separate and independent combs. Each independent comb has a manually operated plunger which forces a hair product through the comb and out of a set of outlets in the teeth of that comb. By withdrawing the plunger, liquid is suctioned through the teeth and into the comb.

  • Patent number: 7538688
    Abstract: Temporary safety zones are established by deploying a plurality of safety icons connected by extensible, brightly colored, retro-reflective tapes. The tapes are retracted within the housings of the safety icons. A plurality of modules having different functions are removably affixed to the base of the safety icons, the modules including sensors, beacons, transceivers, detection devices, and audio receivers and video cameras. Because the modules are manually interchangeable, the safety zones can be implemented for specific, interchangeable circumstances, e.g., a surveillance station, portable helipad, landing strip, and restricted area barriers.

  • Patent number: 6971329
    Abstract: A collapsible traffic control cone includes a lane marker for delineating lines of demarcation between lanes approved for traffic flow and areas where traffic is prohibited. When in use, the lane marker extends from a rotatable housing mounted on one of the cones and is releasably attached to an anchor on an adjacent cone. The lane marker is a flat, highly reflective web which lies flat on the roadway between the cones. In the event of a cone being tipped over from its base or when not in use, the lane marker retracts into its housing. A light responsive to oncoming traffic is also provided.
