摘要： A seed counter for counting seeds flowing through a duct includes a light transmitter on one side of the duct and light receiver on the opposed side of the duct together with an electronic circuit effecting analysis of the signals received by the receiver to generate a seed count value which represents accurately as possible the number of seeds passing through the duct. The transmitter and receiver each comprise a channel-shaped body with diodes at a base of the channel with the channel filled with a translucent potting material facing into the duct. The circuit receives the signals which include for each passage of a seed or a clump of seeds a temporary reduction in light intensity which is converted to a reduction in voltage. Prior to start up the steady state voltage is measured and the current to the transmitter varied to provide a predetermined level of signal at the receiver. The circuit includes a DC compression circuit and a AC compression circuit at an amplifier so as to provide an output signal in a required amplitude range. An autobiasing section maintains a steady state signal at a required level. The amplitude of the signal is compared to a threshold by generating a first signal which is offset by the threshold and a second signal which is delayed by a predetermined time period, the comparison generating a square wave output when one of the signals crosses the other signal. The seed counter is used in a monitoring system having a central monitor which can be operated to vary the parameters of the comparison circuit including the time delay. The use of the comparison circuit assists in determining the difference between a single seed and a clump of seeds passing the transmitter/receiver simultaneously.

摘要： A radar transducer has a planar array antenna mounted on a plate portion of a housing with the microwave transceiver mounted on the opposite side of the plate and carrying a PCB defining the processing section for supplying an output to a cable. The plate portion slides into a plastic receptacle defining the radome for the antenna with a potting compound sealing the open face of the receptacle. The electrical processing section is shielded from extraneous electromagnetic waves without additional metallic shielding elements. The processor is programmable in response to signals received through the output cable so as to re-configure the program thereof so as to change the output to the output cable for different end use controllers and for compatibility with communications protocols. The processor is programmed to carry out a test of the operation of the transceiver and to provide a failure output signal to the cable in the event that the operation is found to be outside predetermined parameters.

摘要： A signal indicative of a distance from a first element to a second element, such as the end face of a piston from the end wall of its cylinder, is generated by providing an optical imager carried on a housing that is fixed on the end wall with the optical imager pointed to the end face. An image processor is arranged to identify image components, such as the end nut on the piston, from the acquired images of the first element. From the location of the nut the processor can identify the location of the outer edge of the circular end face and can determine the area of the end face in the image by counting pixels within the area. From the measured area as it appears in the image the distance can be calculated. The end face is illuminated by a light source shining through a light pipe passing through a drilled hole in the end wall. Characteristic markings can be applied on the end face for measuring distance when the nut is too close to be visible.
