| A system for reliable detection of an approaching train and warning the roadway workers in proximity of the track is described. The system comprises at least one train detector cone (TDC) deployed along a side of an active railroad track and one or more personnel warning cones (PWC) placed near the work site, the cones configured in a wireless mesh network to provide redundant communication links. Detection of a train by the train detector cone is transmitted to the personnel warning cones which provide audible and visual warnings to nearby roadway workers. The system also includes a remote server for centralized tracking and monitoring of the train detector cones and personnel warning cones. | ||||||

| The present invention is directed to a vehicle barrier system and method of use. The vehicle barrier system includes a control system adapted to pivot a gate arm between a horizontal position and a vertical position to control the flow of vehicle or pedestrian traffic in control access areas such as parking lots, or parking garages. The gate arm includes inset channels that are disposed along the longitudinal axis of the gate arm and configured to each remove ably receive an array of light emitting diodes to increase visibility and alert drivers or pedestrians to the presence of a gate arm. | ||||||

| A system is provided for monitoring power consumption of a light emitting diode (LED) lamp. The system includes a first sensor, a second sensor and a processor. The first sensor is associated with a voltage level. The second sensor is associated with a current level light emitting diode and a monitoring module. Further, the processor is configured to receive a voltage signal from the first sensor and a current level signal from the second sensor and determine a power level consumption of the LED lamp. | ||||||

| There is provided a radar system that includes an emitter system (e.g., an antenna), configured to emit electromagnetic pulses and detect electromagnetic pulses, and a reflection target, placed opposite the emitter system. The emitter system and the reflection target define an area of interest. A controller is configured to identify a reflection from the reflection target and, if the reflection is not identified, to stop sending a radar check signal. The radar system may be part of a warning horn control system, where the radar check signal is used as a control input for activating a warning horn. | ||||||
