Abstract: 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.

Abstract: An electrical load balanced heating system and method. The load balanced heating system and method is configured to facilitate smooth electrical operation as well as energy savings. The system is configured to group the heating elements based on load characteristics of the heating elements and turn the groups on and off sequentially in a matter that promote efficient and smooth operations.
