Abstract: A refrigerator appliance includes a cabinet that defines first and second compartments. A fan assembly is configured to direct cooled air from a cooling assembly into the first and second compartments. The fan assembly includes a housing that defines an inlet, a first outlet, and a second outlet. The first outlet is in communication with the first compartment, and the second outlet is in communication with the second compartment. A fan is positioned within the housing and is configured to direct the cooled air from the inlet toward the first and second outlets. A damper assembly is configured to selectively obstruct one of the first outlet and the second outlet.

Abstract: A fan assembly including a housing, an impeller, a first damper member, a second damper member, and an actuation assembly. The housing defining a number of outlets and the impeller being configured to rotate about a rotational axis to direct air towards the number of outlets. The first damper member at least partially extending circumferentially about the impeller and the second damper member at least partially extend circumferentially about the impeller. The actuation assembly is configured to selectively rotate the first damper member and/or the second damper member to partially block, completely block or completely open the number of outlets.

Abstract: An apparatus to analyze a biological sample contained in a container, comprising an examining device able to perform an optical measurement on the biological sample, based on light-scattering technology, at least of the bacterial growth in the biological sample. The examining device is provided with emitter means able to emit a first light beam toward the container of the biological sample and sensor means able to detect at least a light beam diffused from the container of the biological sample and to transmit a relative signal, correlated to the light beam diffused, to a control unit which is able to process, directly or indirectly, the signal in order to verify at least the possible bacterial growth in the biological sample. The container is disposed along a determinate lying plane and comprises at least a containing micro-element able to contain at least a part of the biological sample and inside which a liquid culture ground is provided so as to allow bacterial growth in the biological sample.

Abstract: A method for the bacterial investigation of a biological sample, which provides to carry out a light scattering reading in order to determine the turbidity according to the McFarland standard of a suspension formed from a liquid culture means or eugonic medium in which the biological sample is inoculated, and in which the turbidity is continuously measured directly from the suspension of the sample analyzed during the growth step of the bacteria, until a determined threshold of turbidity is reached expressed according to the McFarland standard.
