Abstract: The present invention comprises an automated warning system for uncontrolled railway crossings. This system has elements which include a real-time communication low earth orbit satellite system in conjunction with mobile devices, a crossing satellite beacon, a crossing motion detection system, and a real-time situational monitoring system that establishes warning alerts to both the train operator and vehicle operator all on a real-time basis. The present invention's various elements together are meant to address the inherent dangers of uncontrolled railway crossings by providing cost-effective improvements that will reduce tragic accidents/loss of life, reduce lawsuits and damages.

Abstract: A container has at least one seam, the at least one seam having a joined portion and an unjoined portion. A seal seals the unjoined portion of the seam, the seal being operative to fail due to internal pressure before a remainder of the container. The container may be cylindrical, comprise metal and have at least one longitudinal seam. Generally, the joined portion comprises a weld. The seal may comprise one or more of a fluid adhesive, a gasket, a patch and an I-shaped gasket. A cover attached to the container with fasteners may at least partially cover the seal to protect it from damage.

Abstract: A waveform equalizing system includes a clock reproducing phase locked loop circuit for reproducing a clock signal from a television signal; a transversal filter; a first selector circuit for alternatively passing the television signal or an output of a first memory to the transversal filter; a CPU for extracting reference signals contained in the television signal from the input and output of the transversal filter through two second memories respectively and for performing a synchronous addition of the same; the first memory for storing a reference signal processed by the synchronous addition; and a second selector circuit for alternatively delivering the television signal or an output of the transversal filter in response to a control signal from the CPU.
