Abstract: A fail-safe circuitry for a vehicle barrier security system prevents accidental raising of the barrier due to inadvertent closing of an activation relay causing power to be provided to an activation mechanism raising the barrier. A latching relay, having a latched state and reset state, is placed in series between the activation relay and the activation mechanism. The latching relay is reset whenever the OPEN switch is pressed for lowering the barrier or an automatic reset relay is energized by a controller whenever passage of a vehicle is sensed. Prior to raising the barrier, the latching relay must be reset, which can occur by pressing the OPEN switch or by the controller detecting passage of a prior vehicle and activating a automatic reset relay. Accidental raising of the barrier due to malfunctions of the activation relay due to vibrations is prevented by latching and resetting the latching relay.

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.
