Abstract: Systems and methods for displaying projected image onto a surface to create an active augmented reality environment may include a lighting device and a controller. The controller may receive information, such as a user input or sensor information, and determine one or more projection properties for the lighting device. The lighting device may receive a control signal from the controller and adjust one or more parameters in order to project the image onto the surface in accordance with a desired user input and the sensor information.

Abstract: The disclosure presents a system for remotely managing emergency equipment through wireless network and methods to use this system to monitor emergency equipment and deliver emergency information to subscribers. The system for remotely managing emergency equipment includes at least a node, also called as end user emergency equipment, a remote server, and a plurality of direct and indirect subscriber devices. The remote server receives data collected from each node, processes the node data, and sends the processed data to direct and indirect subscribers to manage emergency equipment. The system can improve the efficiency on collision avoidance, emergency warning, and emergency vehicle dispatch management.

Abstract: A self-assembling network is configured to automatically and dynamically connect devices used in operations carried out on or near roads bearing vehicle and pedestrian traffic. An automatic, ad hoc network connecting existing and new devices can be used to enhance safety by gathering and exchanging safety critical information. In some cases, existing equipment can be augmented with a network controller and radio frequency communications to permit the devices to join a wireless local network and exchange information over the network. New devices, including wearable devices, can be configured to act as nodes on the wireless local network. Establishing the relative position of vehicles, sensors, wearables, and other nodes on the disclosed ad hoc wireless network allows the coordination of functions based on position.

Abstract: A warning system for use on a first vehicle includes a warning device connected to a control assembly. The control assembly includes a controller, a processor, a memory and a power supply. A GPS receiver is connected to the control assembly for determining the geographic location of the vehicle and for acquiring a local map of the vicinity of the vehicle. The control assembly also includes an intersection detection system for identifying a target intersection being approached by the vehicle and is configured to determine whether the vehicle is in the proximity of the target intersection. The control assembly also is configured to activate the warning system to issue a warning when the vehicle is within the predetermined proximity of a target intersection.
