Abstract:
A cross-flow heat exchanger, method of making a cross-flow heat exchanger, and a dehumidifier are provided. The cross-flow heat exchanger has an axial flow path extending through the heat exchanger from an inlet to an outlet and a transverse flow path oriented transversely to the axial flow path and extending through the heat exchanger from an inlet to an outlet. The transverse flow path is adjacent to and separate from the axial flow path. The surface area of the inlet of the axial flow path is less than the surface area of the outlet of the axial flow path. In a preferred embodiment, the heat exchanger has an exterior shape that is trapezoidal.
Abstract:
A robotic attacher retrieves cups from the left side of an equipment area located behind a dairy livestock and attaches the cups to the teats of the dairy livestock in sequence. The sequence comprises attaching a first cup to the left front teat, a second cup to the right front teat, a third cup to the left rear teat, and a fourth cup to the right rear teat.
Abstract:
A system includes a robotic attacher comprising a main arm and a supplemental arm operable to extend into a stall portion of a milking box. A camera couples to the supplemental arm. The supplemental arm comprises a camera-facing nozzle operable to spray the camera with a cleanser.
Abstract:
An apparatus comprises a milking box having a stall to accommodate a dairy livestock and a robotic attacher. The robotic attacher comprises a main arm that is suspended vertically from a rail of the milking box, and a supplemental arm that is coupled to and extends horizontally from the main arm along a longitudinal axis. The supplemental arm comprises a pivot assembly that pivots a gripping portion around a vertical axis that is substantially parallel to the main arm of the robotic attacher, in a direction transverse to the longitudinal direction of the supplemental arm.
Abstract:
A system comprises a robotic arm operable to extend between the legs of a dairy livestock located in a milking stall of a rotary milking platform, a camera operable to generate an image signal corresponding to a rear of the dairy livestock, and a controller communicatively coupled to the robotic arm and the camera. The controller determines whether a milking claw is attached to the teats of the dairy livestock by receiving the image signal generated by the camera and processing the image signal. If it is determined based on the image signal that the milking claw is not attached, the controller controls the robotic arm to extend between the legs of the dairy livestock. If it is determined based on the image signal that the milking claw is attached, the controller controls the robotic arm not to extend between the legs of the dairy livestock.
Abstract:
A system comprises a memory operable to store light intensity information for a plurality of neighboring pixels of an image that includes a dairy livestock. The system further comprises a processor communicatively coupled to the memory. The processor determine that a difference between the light intensity information for a first pixel of the plurality of neighboring pixels and at least some of the other neighboring pixels exceeds a threshold. The processor further discards the first pixel and determines a location of a teat of the dairy livestock based on the image, excluding the discarded pixel.
Abstract:
A spray tool coupled to a robotic arm includes a linear member, a first spray nozzle and a second spray nozzle. The linear member rotates about an axis that is perpendicular to the robotic arm. The linear member has a perimeter that lies within an outer perimeter of the robotic arm when the robotic arm extends between the legs of a dairy livestock. The first spray nozzle is coupled to the linear member proximate a first end of the linear member. The second spray nozzle is coupled to the linear member proximate a second end of the linear member.
Abstract:
An apparatus comprises an air inlet configured to receive an inlet airflow. The inlet airflow comprises a process airflow and a bypass airflow. An evaporator unit receives a flow of refrigerant and is cools the process airflow by facilitating heat transfer from the process airflow to the flow of refrigerant. A condenser unit receives the flow of refrigerant and (1) reheats the process airflow by facilitating heat transfer from the flow of refrigerant to the process airflow, and (2) heats the bypass airflow by facilitating heat transfer from the flow of refrigerant to the bypass airflow. The process airflow is discharged via a process airflow outlet and the bypass airflow is discharged via a bypass airflow outlet.
