摘要： A method and apparatus for marking a line, such as the centerline, along a roadway, using a vehicle carrying paint marking apparatus, in which a pair of television cameras, one mounted on each side of the vehicle, view the edges of the roadway and project the images onto a split screen. By keeping the images on the screen in a predetermined relationship the operator can steer the vehicle in a path along the roadway uniformly spaced from its edges. Preferably a third camera, centrally located on the vehicle, views the vanishing point of the roadway when straight and the image of the vanishing point is registered with a predetermined mark associated with the screen.

摘要： A device for indicating grain loss resulting from unthreshed heads in a combine harvester using a microwave transmitter-sensor. The device provides an output signal whose magnitude is a function of the mass of passing effluent which when compared to that of a typical threshed head provides a measure of unthreshed head grain loss.The device further provides that the output signal for unthreshed heads is distinct from that of loose grain providing means of distinguishing unthreshed head grain loss and loose grain loss.

摘要： A grain flow rate monitor has a high sensitivity for the detection of seed loss in the chaff ejected from a thresher, which may be used for monitoring heavy or light seed grains. The monitor includes an acousto-electric sensor upon which the chaff impinges to produce a wide frequency spectrum signal. This signal is passed through two or more band pass filters which are centered at predetermined frequencies. When two filters are utilized, they will each have a predetermined bandwidth, one of which is contained in the 0 to 25 kHz range and the other contained in the 25 to 100 kHz range. The filter outputs are coupled to detectors for detecting either the peak amplitudes in each band or the average amplitude. These detector amplitudes are compared in a comparator to determine whether the ratio of their magnitudes fall within a predetermined ratio range which is indicative of a seed striking the sensor. The comparator thus provides output pulses related to seed strikes which are recorded and/or displayed for the thresher operator.
