| 20080316055 | Emergency Vehicle Traffic Signal Preemption System - An emergency vehicle traffic light preemption system for preemption of traffic lights at an intersection to allow safe passage of emergency vehicles. The system includes a real-time status monitor of an intersection which is relayed to a control module for transmission to emergency vehicles as well as to a central dispatch office. The system also provides for audio warnings at an intersection to protect pedestrians who may not be in a position to see visual warnings or for various reasons cannot hear the approach of emergency vehicles. A transponder mounted on an emergency vehicle provides autonomous control so the vehicle operator can attend to getting to an emergency and not be concerned with the operation of the system. Activation of a priority-code (i.e. Code- | 12-25-2008 |
| 20090189782 | CELLULAR-BASED PREEMPTION SYSTEM - A cellular-based preemption system that uses existing cellular infrastructure to transmit preemption related data to allow safe passage of emergency vehicles through one or more intersections. A cellular unit in an emergency vehicle is used to generate position reports that are transmitted to the one or more intersections during an emergency response. Based on this position data, the one or more intersections calculate an estimated time of arrival (ETA) of the emergency vehicle, and transmit preemption commands to traffic signals at the intersections based on the calculated ETA. Additional techniques may be used for refining the position reports, ETA calculations, and the like. Such techniques include, without limitation, statistical preemption, map-matching, dead-reckoning, augmented navigation, and/or preemption optimization techniques, all of which are described in further detail in the above-referenced patent applications. | 07-30-2009 |

| 20100182340 | SYSTEMS AND METHODS FOR COMBINING VIRTUAL AND REAL-TIME PHYSICAL ENVIRONMENTS - Systems, methods and structures for combining virtual reality and real-time environment by combining captured real-time video data and real-time 3D environment renderings to create a fused, that is, combined environment, including capturing video imagery in RGB or HSV/HSV color coordinate systems and processing it to determine which areas should be made transparent, or have other color modifications made, based on sensed cultural features, electromagnetic spectrum values, and/or sensor line-of-sight, wherein the sensed features can also include electromagnetic radiation characteristics such as color, infra-red, ultra-violet light values, cultural features can include patterns of these characteristics, such as object recognition using edge detection, and whereby the processed image is then overlaid on, and fused into a 3D environment to combine the two data sources into a single scene to thereby create an effect whereby a user can look through predesignated areas or “windows” in the video image to see into a 3D simulated world, and/or see other enhanced or reprocessed features of the captured image. | 07-22-2010 |

| 20100330542 | SYSTEMS FOR AND METHODS OF SIMULATING FACILITIES FOR USE IN LOCATE OPERATIONS TRAINING EXERCISES - Systems for and methods of simulating facilities for use in locate operations training exercises are disclosed. Embodiments of the simulated facilities systems include a floor system in which one or more concealed wires may be energized to simulate underground facilities for the purpose of performing, for example, locate operations training, updating, and/or certification exercises for locate technicians. Embodiments of the simulated facilities systems include configurable pedestals by which either non-electric power line type of facilities and/or electric power line types of facility may be simulated. In some embodiments, simulated facilities systems may be configured manually and/or by use of a system controller. | 12-30-2010 |
| 20110020776 | LOCATING EQUIPMENT FOR AND METHODS OF SIMULATING LOCATE OPERATIONS FOR TRAINING AND/OR SKILLS EVALUATION - Training systems for and methods of simulating locate operations are provided for training and/or skills evaluation. Facility locating equipment, such as on-site computers and/or locate receivers, may include modules for electronically simulating locate operations. Locating equipment including simulation modules may be used, for example, in locate technician training processes and/or for updating and/or evaluating the skills of locate technicians. In particular, a simulation module is provided for electronically generating “virtual” facilities, the presence and/or absence of which may be indicated to a locate technician during, for example, a training exercise. The actions of the locate technicians with respect to dispensing marking material that corresponds to the presence and/or absence of the virtual facilities are electronically captured, stored, and evaluated. | 01-27-2011 |
