摘要： A circuit is provided for a seed sensor which includes a light source and a light responsive element respectively positioned along a path of travel of seeds for producing a momentary change in signal level from the light responsive element in response to a momentary change of level of light incident thereupon from the light source due to the passage of one or more seeds therebetween. In accordance with the invention, the circuit comprises a pulse-producing circuit responsive to the change in signal level from the light responsive element for producing a discrete pulse signal in response to each change in the direction of the change in signal level. Predetermined ones of the discrete pulse signals are selected for counting.

摘要： The present disclosure is to realize a fish counting device which can simply count fish at low cost. The fish counting device 1 includes an ultrasonic transducer 2 and a processor 4. The ultrasonic transducer 2 transmits an ultrasonic beam 9 underwater in a first fishtank 11 connectable with a second fishtank 12 through a path 13, and is provided with a transducer element arranged in a single channel. The transducer element is disposed at a position where the ultrasonic beam 9 does not intersect the path 13. The processor 4 outputs to the ultrasonic transducer 2 a transmission signal to drive the ultrasonic transducer 2, and acquire a number of fish passing through the ultrasonic beam 9 and moving from the path 13 to the first fishtank 11 based on an echo signal inputted from the ultrasonic transducer 2 that received a reflection wave.

摘要： A person count management apparatus for managing a person count for each time period based on image data obtained by image capturing means, sets one of a region person count that counts the number of persons existing in a predetermined region of the image data and a passing person count that counts the number of persons passing a predetermined line set in the image data, and displays a person count result from the image data on a display unit in accordance with the setting, wherein if the region person count is set in the setting step, a still image captured by the image capturing means in a time period corresponding to a selected person count result is displayed, and if the passing person count is set in the setting step, a moving image captured by the image capturing means in a time period corresponding to the selected person count result is reproduced.

摘要： Systems, apparatuses, and methods of classifying flying insects. The methods utilize recording the wingbeat frequency and amplitude spectrum of flying insects and comparing them to known or created insect models to properly classify the flying insect. The error rate of the classification is reduced by utilizing multiple inputs to the classification system, which may include a precise circadian rhythm for the time of year, current environmental conditions, and flight velocity or direction.

摘要： Chick counter device and method. The counter comprises a camera, a chick supply line passing the scope of the camera, and a data processing unit communicating with the camera and programmed to process images captured by the camera to identify and count individual chicks by comparing a plurality of subsequently captured images. The data processing unit can, e.g., be programmed to count individual chicks passing a virtual line at the lower end of the camera scope in an image captured by the camera. Subsequently it compares the image with one or more earlier captured images to trace back the path of the individualized chicks. The number of counted chicks is corrected if a chick counted for one in step a appears to be countable for two or more chicks in at least one earlier captured image. The camera can e.g. be a videocamera.

摘要： A method and an arrangement for detecting and counting articles are disclosed, performing the steps of: • - providing a detecting station (20) arranged along a passageway (16) for the articles (W), the detecting station (20) being adapted to establish at least a scanning radiation beam (R) at a cross section of the passageway (16); • - passing articles (W) past the detecting station (20), the detecting station (20) detecting an article (W) upon sensing at least a partial interruption of the scanning radiation beam (R); and • - obtaining a count of the detected articles (W) through the passageway (16), wherein the detecting station (20) include first and second detecting assembly (22a, 22b) arranged at a predetermined distance (d) from each other along the direction of travel (Z) of the articles (W), which first and second detecting assembly (22a; 22b) establish a respective scanning radiation beam (R) on a first, respectively second scanning plane (A; B) at a corresponding cross section of the passageway (16), and wherein • - at least a first predetermined reference section of the articles (W) is detected at each scanning plane (A, B); • - a travelling speed of each article (W) is calculated based on the time used by the at least one reference section of the article (W) to travel the predetermined distance (d) between the first and the second scanning planes (A, B); • - at least a second predetermined reference section of the articles (W), which is separate from the first reference section, is detected at least at one of the first and second scanning plane (A; B); and • - a count of the articles (W) is obtained by calculating a length thereof from the calculated travelling speed and by calculating the time used by the article to cross at least one of said first and second scanning plane (A; B).

摘要： The invention comprises a system and an optical device (1) to facilitate the counting of objects, e.g. fish and other organisms living in freshwater or sea, especially when using large-scale equipment in fish-fanning. The system makes it possible to diminish the distance between the recording camera and the objects to be counted.
