WARNING LIGHT ASSEMBLY WITH ORIENTATION SENSOR, AND RAILWAY CROSSING INSTALLATION INCLUDING THE SAME
Publication number: 20230118555Abstract: A warning light assembly and railway crossing including such an assembly are disclosed. An example warning light assembly includes a housing, an illumination device at least partially positioned within the housing, and a movement detection circuit positioned within the housing in a fixed position relative to the illumination device. The movement detection circuit can include a plurality of sensors of different types, and is configured to detect a change in position or orientation of the warning light assembly relative to an initial position, and, in response to detecting the change in position or orientation, generate an alert.Type: ApplicationFiled: October 20, 2022Publication date: April 20, 2023Applicant: Railway Equipment Company, Inc.Inventors: David K. FOX, Jason L. HONECK -
Publication number: 20230093221Abstract: A method of operating a warning light assembly at a railway crossing, as well as a warning light assembly operable in accordance with such a method, are disclosed. An example method includes receiving a voltage signal at the warning light assembly that corresponds to a railway crossing event. The method includes initiating a warning light flashing sequence that includes, during a first time period, illuminating the warning light during receipt of the voltage signal in a flashing pattern having a flashing frequency. The warning light flashing sequence also includes, during a second time period after the first time period, discontinuing the flashing pattern and illuminating the warning light in accordance with the voltage signal. Upon determining that receipt of the voltage signal at the warning light assembly is discontinued for at least for a predetermined time, the warning light flashing sequence is reinitialized for a next railway crossing event.Type: ApplicationFiled: September 23, 2022Publication date: March 23, 2023Applicant: Railway Equipment Company, Inc.Inventors: David K. FOX, Jason HONECK

Publication number: 20210086811Abstract: A railroad crossing light detector system is disclosed. The system includes determining a first signal indicative of the amount of light emitted from an illuminated railroad crossing light source and determining a second signal indicative of the orientation of the crossing light. The first and second signals are transmitted to a signal determination module that compares the first and second signals to predetermined stored values. The compared signals are then provided to a railroad crossing controller for relaying to a central/remote monitoring location. In the event that at least one of the signals is out of range relative to the stored value, then an inspection request signal together with information on the location of the crossing light is provided to the central monitoring location. In this manner, the number of in-person inspections to the crossing light may be significantly reduced.Type: ApplicationFiled: September 11, 2020Publication date: March 25, 2021Inventors: David K. FOX, Randall G. HONECK

Publication number: 20200305236Abstract: An electric heater fault detector for a rail of a railroad track is disclosed. The detector includes a power resistor electrically connected to the rail and a voltage breakdown device connected in series with the resistor to ground. The voltage breakdown device has resistance characteristics of high resistance at low voltages and low resistance at high voltages, and is preferably a metal-oxide varistor. In the event that an electric heater case applies a high voltage from a short in the electric heater to the rail, then the voltage breakdown device conducts and the power resistor and voltage breakdown device provide a path to ground for the rail. The electric heater fault detector may further include a ground fault circuit interrupt attached to the heater, whereby the ground fault circuit interrupts the application of voltage to the heater when it detects a difference in the current to the heater.Type: ApplicationFiled: March 20, 2020Publication date: September 24, 2020Inventors: David K. Fox, John C. Unze
