Abstract: This invention relates to the testing of apparatus used for on-line acoustic detection of bearing defects, particularly in railroad applications. A loudspeaker on each side of the section of track, in response to a microprocessor, generates simulated acoustic signatures characteristics of various bearing defects. The microprocessor additionally sends corresponding simulated train speed signals to the apparatus. The invention monitors the apparatus for the appropriate alarm signal.

Abstract: An improved method and circuit is provided for processing waveforms from a railway car heat signal to eliminate spurious signals and to differentiate between roller bearings and friction bearings in a railroad hot box detector system. The waveforms generated by passing bearings are discretely sampled and spurious signals are eliminated by considering only those signals that fall within the crossing points of a threshold value. Discrimination between roller bearings and friction bearings is obtained by determining the ratio of the sum of the discrete values of the amplitude of the waveform within a first set of samples between the crossing points to the sum of the discrete values of the amplitude of the waveform within a second set of samples between the crossing points.

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: OBJECT IDENTIFICATION SYSTEM UTILIZING CLOSED CIRCUIT TELEVISION 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: An acoustic system for detecting defects in the bearings of moving railroad cars and identifying the location of these defects has means for opening a window on detection of a wheel passing a particular point such that signals received relate only to the bearing and extraneous signals are excluded.
