Abstract: A roadside signal system and a roadside controller are provided relating to the control and operation of roadside signals and signs, such as those used by departments of transportation and municipalities. The roadside signal system and controller are configured to operate using National Transportation Communications for Intelligent Transportation Systems Protocol (“NTCIP”) compliant transmissions at both a local and remote level. The roadside controller by itself and as a part of the roadside signal system operates a local network to control multiple signs or signals from a single connection to a central network, thus saving physical space within the roadside cabinets used to store such controllers and virtual network space on the central network.

Abstract: A display device is disclosed having a base member adapted to receive at least one light device, conductive layer provided on the base member and configured to electrically interconnect with the light device, and a light guide member integrally formed on one or more of the base member and conductive layer, and having at least one aperture configured to at least partially surround the light device. A method of making a display device is also disclosed and includes the steps of providing a base member having a conductive layer provided in a pattern thereon, forming a light guide member having at least one aperture onto at least one of the base member and the conductive layer, and attaching at least one LED to the conductive layer so that the LED is disposed within the aperture.
