Abstract
A system for the programmed flashing of a plurality of highway warning lights includes a plurality of slave receivers each associated with a warning light to be mounted on respective barricades along with one or more master transmitters associated with certain receivers and warning lights. The master transmitter provides a coded signal which causes the warning lights to flash either in synchronization or in a predetermined sequence. Fail safe operation is provided by the use of a substitute master if the original master is disabled. The programmed flashing provides for greater depth perception by the approaching driver.
Claims12
In a system for operating warning lights disposed along a street or highway traveled by a motorist, a plurality of spaced barricades, a plurality of warning lights respectively carried by said barricades and positioned along the street or highway to provide a warning to a motorist, said lights to be controlled in a pattern as to give an impression of depth to the motorist along the lane of travel by the motorist, each of said warning lights having a power supply, a lens assembly and a lamp mounted in the lens assembly, master transmitter means for providing an electromagnetic signal which is transmitted through the air;
- receiving means associated with said warning lights for receiving said transmitted signal and for intermittently connecting said lamp to said power supply so that the warning lights are flashed to give a perception of depth along the line of travel by the motorist.
A system for the programmed flashing of a plurality of temporarily positioned highway warning lights controlled in a pattern to give a perception of depth to a motorist comprising:
- receiving means mounted with each of said warning lights for receiving and decoding a frequency coded electromagnetic signal said receiving means including energizing means responsive to said receipt of said electromagnetic signal for energizing said warning lights;
- master transmitter means for providing said electromagnetic signal for continuously actuating directly said energizing means and being in a stationary position with respect to said receiving means and being sufficiently close to said plurality of warning lights so that said flashing of said lights is controlled concurrently and continuously by said master transmitter in accordance with said code.
