Collision avoidance system

Abstract: The Collision Avoidance System prevents vehicular collisions between vehicles and with pedestrians, trains, and stationary objects by monitoring (50), controlling (40), documenting, and reporting (60) the speed and position of vehicles. The system guards against speeding violations, moving violations, and particular safety hazards by invoking a reduction of vehicle speed or by restricting vehicle movement to control its position. This is primarily accomplished with the activation of a controllable road perturbation (20). The system also monitors pedestrians, school bus loading/unloading, traffic density, trains, road moisture, and traffic control systems to determine the action to take for collision prevention. The capability to monitor various entities that may be involved in a collision or entities that indicate a possible collision is forthcoming allows the system to monitor an entire traffic environment and thus anticipate possible collisions. The system integrates and synchronizes with existing traffic control devices and systems to ensure that it reinforces the traffic laws and safety intent of the environment in which it is installed. A computer (10) is used to determine if the vehicles are adhering to the traffic laws or other safety concerns. Visual displays (70) may accompany the system output to inform the motorist what must be done to prevent a collision.

Systems and methods for managing and detecting fraud in image databases used with identification documents

Abstract: We provide a system for issuing identification documents to a plurality of individuals, comprising a first database, a first server, and a workstation. The first database stores a plurality of digitized images, each digitized image comprising a biometric image of an individual seeking an identification document. The first server is in operable communication with the first database and is programmed to send, at a predetermined time, one or more digitized images from the first database to a biometric recognition system, the biometric recognition system in operable communication with a second database, the second database containing biometric templates associated with individuals whose images have been previously captured, and to receive from the biometric recognition system, for each digitized image sent, an indicator, based on the biometric searching of the second database, as to whether the second database contains any images of individuals who may at least partially resemble the digitized image that was sent. The a workstation is in operable communication with the first server and is configured to permit a user to review the indicator and to make a determination as to whether the individual is authorized to be issued an identification document or to keep an identification document in the individual's possession.

Tool position and identification indicator displayed in a boundary area of a computer display screen

Abstract: An endoscope captures images of a surgical site for display in a viewing area of a monitor. When a tool is outside the viewing area, a GUI indicates the position of the tool by positioning a symbol in a boundary area around the viewing area so as to indicate the tool position. The distance of the out-of-view tool from the viewing area may be indicated by the size, color, brightness, or blinking or oscillation frequency of the symbol. A distance number may also be displayed on the symbol. The orientation of the shaft or end effector of the tool may be indicated by an orientation indicator superimposed over the symbol, or by the orientation of the symbol itself. When the tool is inside the viewing area, but occluded by an object, the GUI superimposes a ghost tool at its current position and orientation over the occluding object.

Systems and methods for analyzing sensor data

Abstract: The invention relates to systems and methods for analyzing data collected from sensors monitoring property. In particular, the systems and methods analyze the data to make property insurance underwriting decisions based on the collected sensor data using a computerized process that varies the way in which it manipulates the collected sensor data based on a characteristic of the property being insured, a characteristic of the entity seeking the insurance, and/or on the value of one or more collected data parameters. The invention also relates to systems and methods of making property insurance pricing decisions based on a similarly dynamic computerized process.

System and method for providing pedestrian alerts

Abstract: A system and method for generating pedestrian alerts are provided. Vehicle operators are provided with alerts regarding potential vehicle-pedestrian collisions and other dangers involving pedestrians. Additionally, pedestrians may be provided with alerts regarding potential dangers, including dangers of vehicle-pedestrian collisions. Mobile devices, which can be carried or worn by pedestrians, respond to activation signals from a vehicular device. The vehicular device receives positional information from each mobile device within transmission range, and determines relative positions of each of the mobile devices with respect to the position of the vehicular device. A determination of the probability of intersection of any mobile device with a warning zone near the vehicular device is calculated and predicted according to pre-determined rules. If the probability of intersection meets or exceeds a pre-determined threshold, an alert is generated.

Medical robotic system with coupled control modes

Abstract: In a coupled control mode, the surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled slave manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the surgeon's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the surgeon to better focus on performing medical procedures and to pay less attention to managing the system.
