Abstract: A sprinkler has an internal cavity where fluid is configured to flow through the internal cavity along a flow path extending from an inlet to an outlet. A sprinkler head is in fluid communication with the internal cavity of the body and is rotatable about a sprinkler head axis. A sprinkler power assembly generates electrical power for diagnostics of the sprinkler, such as a motion sensor oriented toward the sprinkler head. The motion sensor is configured to emit a motionless signal upon the sprinkler head ceasing to rotate about the sprinkler head axis.

Abstract: The process of producing concentrated maple sap can include concentrating the maple sap using membrane filtration to a sugar content of approximately 30° Brix, circulating the maple through a maple sap passage of a membrane, wherein the membrane contains the maple sap in a vacuum cavity, and evaporating the water from the maple sap across the membrane into the cavity. The concentrated maple sap having a sugar content above 50° Brix.

Abstract: The process of producing maple syrup from maple sap can include concentrating the maple sap to a sugar content of between 30 and 50° Brix using membrane filtration, including increasing a differential pressure of the membrane filtration in accordance with an increasing of an osmotic pressure as the sugar content increases to eventually reach the sugar content of between 30 and 50° Brix; and subjecting the concentrated maple sap having a sugar content of between 30 and 50° Brix to evaporation until it transforms into maple syrup.
