摘要： A method and system are provided for automatically determining the position and attitude of a three-dimensional body at a work station by utilizing three cameras each of which generates a non-overlapping plane of image data, including a single target point of the body without the use of structured light. The locations of the target points are determined and processed within a programmed computer together with calibration data relating to the expected position of the body in the work station to provide data relating to the position and attitude of the body with respect to the work station. The resultant data relating to the position and attitude of the body are subsequently transformed into a first set of offset data relating to the difference between the actual and expected positions of the body. The first set of offset data is then transformed into a second set of offset data in the coordinate system of a peripheral device such as a robot, programmable controller, numerically controlled machine, etc. Finally, the programmed computer transfers the second set of offset data to the peripheral device which utilizes the data to modify its pre-programmed path.

摘要： The present invention is a roadside safety system and method to communicate to a roadside personnel a potential danger created by an oncoming vehicle. The system includes a projection system that selectively projects a pattern of light in a direction along the roadside, a sensor system that includes a camera to detect the oncoming vehicle, an alert system connected directly or indirectly to the sensor system that selectively causes an alert to notify the roadside personnel when there is the potential danger; and a control system that selectively enables the projection system to project the pattern of light and causes the alert system to issue the alert. The projection system establishes a virtual flare on the road to warn oncoming vehicles of a emergency situation and a processor can process information received by the sensors and can then determine potential threats created by oncoming vehicles.

摘要： A method and apparatus are disclosed for reducing traffic flow instabilities and increasing vehicle throughput by monitoring the distances and velocities of motor vehicles leading and following a center vehicle and controlling the velocities of the vehicles to maintain a steady relative distance between the center vehicle and the leading and following vehicles. Using distance and speed information derived from both leading and following vehicles reduces the loop gain of feedback needed below one (1) and diminishes traffic instabilities caused by “car following.”

摘要： An analog VLSI microchip which uses moments to determine the position and orientation of an object in a scene is disclosed. The imaging sensors are implemented on the chip itself using standard fabrication processes. The method allows very high speed computation in a small, low cost, and low power device. The first moments determine the centroid of the image, which provides the position. The second moments, together with the first moments, determine the axis of least inertia, which provides the orientation. The method uses a resistive grid with nodes containing intensity data (in the form of voltages) corresponding to the image. The moment extraction method is a two-stage dimensional reduction of data. First, the two-dimensional array of intensity data is reduced to a one-dimensional array of data (in the form of currents) by the resistive grid. Second, the one-dimensional data array, which is available at the periphery of the grid, is reduced to a data vector, the size of which is independent of the grid size.

摘要： A small but very efficient X-ray detector operating in a current integrating mode for use in high speed tomography apparatus comprises a scintillator that is entirely coated with a highly reflective matte material except for a relatively small-area window. A P.I.N photo-diode is juxtaposed with the scintillator opposite the window and the two are secured together at an optical interface comprising a transparent adherent material preferably having an index of refraction between the indices of the scintillator and the photo-diode. The ratio of the active surface area of the photo-diode to the area of the scintillator coated with reflective material is appreciably less than unity.
