Multiple designs and methods for aerodynamic separation nozzles and systems for integrating multiple aerodynamic separation nozzles into a single system are disclosed herein. The receiver includes a first antenna, a second antenna, a system controller, a national broadcast demodulator, a local broadcast demodulator, and an information output select device. The device operates in a first mode of reading a pixel signal of every pixel, and a second mode of adding and reading a plurality of pixel signals. A negative terminal of the DC power input terminals has an elastic contact segment. In some embodiments, the apparatus comprises an endoscope comprising a first distal end portion, and a tube comprising a second distal end portion, wherein the endoscope and the tube are in a side-by-side relationship and are coupled at distal end portions of the endoscope and the tube using a single coupling device. According to the invention, said machine foresees at least one guide for the sliding of a container, which collects the product selected near to the corresponding product-holding disc and takes it into a collection position, accessible to the user opening the flap.
