Apparatus, methods, and computer program products are disclosed that teach methods for establishing context of a subsequent electronic real-time communication. A through hole is defined in the center of the plate shaped body. The blockingreleasing carriage may be connected to at least one chute connected to at least one of said cage doors, so as to permit the blockingreleasing of the chutes independently of the actuation of the first motor element and of the cage doors. Then, the actually detected junction voltage of the diode is used to determine the channel of the wavelength, thereby accurately detecting the actual channel wavelength. The separated components having predominantly lean beef can be removed from the liquid as a reduced fat ground beef product.
