Abstract: An improved device for measuring the count and frequency of seeds in a stream of seeds is described. The device is useful for measuring the frequency and accuracy of seed planting devices. A seed counting system can include an imaging region, an image sensing device, and a lens between the imaging region and the image sensing device. An optical distance extender between the imaging region and the lens, creates an effective optical distance between the imaging region and the lens that is substantially greater than the physical distance between the imaging region and the lens, thereby providing a substantial depth of field.

Abstract: The invention refers to a method of selecting stem segments with desired characteristics and more specifically the invention refers to a method of selecting stem segments of graminaceous plants (from the Gramineae/Poaceae family), such as plants of the Saccharum spp, including sugar cane. According to an embodiment of the invention, the method of selecting stem segments, comprises the steps of identifying at least one characteristic of each stem segment by a sensor; and separating the stem segments comprising the said characteristic from those which do not comprise the said characteristic, depending on the response of said identification means; characterized in that the sensor is selected from the group consisting of a pressure transducer sensor, a capacitive sensor, an ultrasound sensor, an x-ray sensor, a magnetic sensor, and a microwave sensor.
