    Abstract: A system to permit the visual observation of objects moving along a fixed path. The object is viewed through a television camera which images the object through an optic axis bending element. The bending element is angularly rotated in a sawtooth manner with the slope of the sawtooth determined by the speed at which the object moves along the path so as to track the object to immobilize the scene viewed by the mirror.

    Abstract: A railroad car hot box detector system is provided which includes a variable circuit means for processing the heat signal generated by an infra-red detector viewing a sensing zone along a section of track. The system includes a conditioning circuit which determines one or more conditions of the train (such as the wheel speed or temperature of the car bottom) and uses that information to vary the processing circuit to enable the heat signal to be processed optimally for the detected condition.

    Abstract: A system is provided for determining whether a railway car passing a sensing station is a freight car. The system utilizes wheel trips along the track at the sensing station to determine the spacing between axles of the car. If the spacing between axles is determined to fall between slightly more than 4' - 5'' to slightly less than 6' - 1'' the car is presumed to be a freight car.

    Abstract: HOT BOX DETECTOR BEARING DISCRIMINATOR CIRCUIT An improved circuit is provided for differentiating between roller bearings and friction bearings in a railroad hot box detector system. The improved circuit integrates the waveform generated by a bearing scanner and compares that to the integral of a pre-selected portion of the waveform. By this method of comparison, irregularities in the system due to noise are obviated.

    Abstract: SCAN ANGLE COMPENSATOR FOR ELECTRO-OPTICAL LABEL READING SYSTEM A scan angle compensator is provided for an electrooptical label reading system of the type comprising apparatus designed to scan an extended range for a coded data label disposed within a portion of the range and a sensor operative in response to light reflected from the label to produce signals representative of the data, wherein the strength of the signals is related to the position of the label within the range. The present compensator includes a function generator the output of which varies inversely to the fluctuation of said signals as said range is scanned and multiplying means receiving as inputs the output of the sensor and function generator and operative to multiply the same so that the amplitude of the output of the multiplier remains constant regardless of the position of the label within the range.

    Abstract: SELF-CLEANING LABEL FOR AUTOMATIC OBJECT IDENTIFICATION SYSTEM A self-cleaning label is provided for use in an automatic object identification system. The label comprises a backing member having a plurality of fins attached to it. A strip of reflective material is affixed to the front surface of each fin for "reading" by the components of the system. The fins are aerodynamically designed so that the flow of air past the label carrying surface serves to clean the surface and protect the settling of dirt thereon.
