Abstract: A system for recognizing objects in images, and using that recognition to solve mission problems, such as identifying, tracking, and reporting movement of mobile military targets of interest. The system incorporates preprocessor and postprocessor with an image correlator, control systems, and feedback loops functioning with a real-time operating system. Tracking includes correlating patterns in an image stream so as to monitor image changes that represent changes of location, shape, trends, or other attributes. Reporting may entail visual displays of correlation results, or other data outputs suitable for steering gimbaled sensors, aiming weapons, or for other functions. The instant invention has application in numerous areas where recognition and tracking of patterns and trends are desired in imagery or in other two-dimensional representations of data.

Abstract: A range and bearing-finding system is disclosed. A diverging encoded laser beam is transmitted to a target, and a return reflection of the encoded beam received. The transmitted beam is sampled, and a plurality of predetermined time delays are applied to the sampled laser beam. The sampled laser beam with each of the predetermined time delays is correlated with the return reflection until a sampled laser beam having a time delay providing the highest correlation is found, the time delay indicating laser travel time to and from the target. Range is determined from this time delay. Bearing of the target is found by using a quadrant protector to receive the return reflection. The process for finding bearing uses the correlation process used to find range.

Abstract: A programmable multifunction electronic camera uses a commercial pixel digital energy sensor to generate detector element signal digital data normally generated by expensive, custom designed, detector element energy sensors. The camera performs this function by retrieving pixel signal digital data and pixel location data from the pixel energy sensor, retrieving detector element energy sensor masks containing information regarding the size, shape, and location of detector elements included in the detector element energy sensors, mapping the pixels included in the pixel energy sensor to the energy sensor masks to identify pixels that can be combined to create “virtual detector elements” having the same size, shape, and configuration as the detector elements in the detector element energy sensors, and combining the pixel signal digital data associated with the mapped pixels to generate the detector digital data. The camera can be programmed with a number of different energy sensor masks and mapping algorithms.

Abstract: A system and method for measuring the dimensions of moving packages includes a computer system connected to a position tracking system and a slice measurement system. The computer system uses the position tracking system to generate a series of position measurements of the packages as they move through the slice measurement system and uses the slice measurement system to generate a cross sectional slice of the packages at each measured positioned. The computer system then uses the cross sectional slice information to determine the height and width of the packages and uses the position measurements to determine the length of the packages.

Abstract: A method of and apparatus for storage and retrieval of resumé images in a manner which preserves the appearance, organization, and information content of the original document. In addition, summaries or “outlines” of resumé images, broken down into multiple fields, are stored, and can be searched field by field. A user interface is provided which is based on a familiar paper-based method already in common use, thus reducing the training required to effectively use the system.

Abstract: An electrophotographic printer 10 having a control system 51 for controlling a stepper motor 50. The control system 51 includes a motor speed drive circuit 52, a microprocessor 54, and a clock 58. The motor speed drive circuit 52 has a programmable driver 56 and a logic circuit 60. The microprocessor 54 outputs a speed change value each time a change in the stepper motor is desired. The programmable driver 56 stores the speed change value and incrementally counts down from the speed change value to zero in synchronization with a clock pulse from the clock 58. Upon reaching zero, the programmable divider 56 outputs a speed command signal to the logic circuit 60, which in turn outputs drive signal to control the operation of the stepper motor 50. The microprocessor 54 only outputs a new speed change value when a change in stepper motor operation is desired. If no change is desired, the programmable divider 56 uses the last input speed value to control the stepper motor.

Abstract: Remote measurement of an angle is very difficult if the angle to be measu is in the plane containing the observer. This is accomplished by using cylindrical lenses and patterns which provide a binary coded image to the remote observer. The binary code represents the angle in the plane containing the observer. Use of microscreens allows the system to be very thin, and even curved around a curved surface, such as a missile. It continuously records an angle of a missile during test flight.
