  • Patent number: 9303853
    Abstract: A collapsible lighting device has a main body surrounded by a collar whose position is adjustable along the longitudinal axis of the main body. Pivotally connected or hinged legs are attached to the collar and to the main body with struts. When the collar is on one position, the legs deploy outward from the main body to the extent permitted by the struts, thereby allowing the legs to support the collapsible lighting device upright. A lamp head is attached to a member which telescope from the main body. When deployed, the lamp head can be switched on to provide illumination. When the collar is another position, the legs are drawn in toward the main body to form a cylindrical shape. The lam head can be positioned so that when the telescoping member is retracted into the main body, the collar surrounds the exterior of the lamp head, thus protecting the lamp head for transport.

    Abstract: An automated gate system (AGS) for processing vehicles entering and exiting a controlled access facility via a single common traffic flow. The AGS provides a single portal receiving both ingress and egress vehicle traffic as a common traffic flow sharing a same access road. The access road feeds a multi-lane gated sub-system having associated kiosks providing an interface for obtaining vehicle and driver related information and which have a combined inbound/outbound gate for controlling ingress and egress movement of vehicles of the common traffic flow in and out from the controlled access facility. A computer system receives signals from the portal and the kiosks representing a status of the vehicles alone or in combination with driver information for controlling gate operation of each of the gates. Thereby, both ingress and egress routes are controlled, and both ingress and egress movement of the vehicles regarding the access facility is controlled.

  • Patent number: 8711004
    Abstract: One estimate indicates that rubbernecking and congestion consumes about 4% of this country's fuel. Two approaches are presented to help solve this problem. The first uses shields to block the view of a car accident. Rubbernecking is reduced since the visibility of the car accident is reduced. A second approach uses mobile flat units that can be remotely controlled to enter a roadway that is carrying active traffic. The traffic runs over these units that are being moved until the master processor indicates that the mobile flat units are in position. A post is extended from the flat unit that issues commands to the motorists so the master processor can begin to control and reduce congestion. Both approaches can be used to help decrease fuel waste in the US.

Further, the road markers may be controlled such that they are commanded to emit the light based upon a timing sequence associated with a desired speed so that the road markers emit light in a strobe pattern. In this way, if a vehicle is traveling at the desired speed, then the strobe pattern appears static to a driver of the vehicle. Additionally, a message may be transmitted from a traffic authority to increase or decrease the timing sequence of the strobe pattern to increase or decrease the speed to the desired speed.

The VLS improves visibility at night for viewers or motorists thereby reducing accidents and damage costs, saves energy, and improves the environment and enhances quality of life by reducing light pollution and light trespass.

  • Publication number: 20110163893
    Abstract: One estimate indicates that rubbernecking and congestion consumes about 4% of this country's fuel. Two approaches are presented to help solve this problem. The first uses shields to block the view of a car accident. Rubbernecking is reduced since the visibility of the car accident is reduced. A second approach uses mobile flat units that can be remotely controlled to enter a roadway that is carrying active traffic. The traffic runs over these units that are being moved until the master processor indicates that the mobile flat units are in position. A post is extended from the flat unit that issues commands to the motorists so the master processor can begin to control and reduce congestion. Both approaches can be used to help decrease fuel waste in the US.

  • Patent number: 7973675
    Abstract: A system includes a plurality of sensors that provide information regarding instantaneous traffic conditions incident to an intersection. An inference engine of the system receives the sensor information and processes user-defined traffic control algorithms and weighted management parameters. Control signals are derived in accordance with the processing. Multi-state signaling devices are driven in accordance with the control signals so as to manage vehicular and pedestrian traffic flow at the intersection. Playback of historic traffic information permits analysis and verification of the traffic management strategies implemented by the system.

  • Patent number: 7889093
    Abstract: A system for displaying safety information—particularly for pedestrian crosswalks and vehicle brake lights—that permits an operator located at a hub to upload and transmit at least one image to select traffic signals or brake light display screen connected within the network. The at least one image depicts a display of regional, local or even neighborhood significance. The operator, or user, can pinpoint which traffic signals will ultimately display these images. The images are locally significant, informative and whimsical.

  • Patent number: 7768428
    Abstract: A Safety Warning Device which when the visual tape and laser mechanisms are components of vertical posts (both primary and corresponding), can be mounted to a base (permanent or portable) or customized to fit on a flatbed trailer, which when the visual tape is extended and the laser mechanism is activated provides both an audible and visual warning, notifying person(s) when they are in danger or in a restricted/unauthorized area. The tape is a visual warning which is high enough to be seen by person(s). The height can be adjusted on both the primary and corresponding posts. The laser is both a visual warning (as the light/laser beam is visible) and an audible warning when the laser connection is disturbed or interrupted. This can be an immediate warning as well as a signal sent to an alternative warning mechanism.

    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.
