Abstract: Low profile object detection can be performed on mowers or other vehicles that may be autonomous. An autonomy controller can be employed on a mower to receive and process sensor data for a detection area to determine whether an object may be present in a region of interest within the detection area. When the autonomy controller determines that an object may be present, it can cause the ground speed of the mower to be slowed and can commence buffering region of interest sensor data over a period of time. The autonomy controller can process the buffered region of interest sensor data to determine whether an object is present in the region of interest, and if so, can alter the path of the mower appropriately.

Abstract: A decorative, nonwoven laminate and a method of forming, including a first side of a first nonwoven affixed to one or both of a) a first side of a polymeric sheet or b) a second nonwoven, wherein the first nonwoven exhibits a basis weight of 15 g/m2 to 2500 g/m2 and the second nonwoven exhibits a basis weight of 15 g/m2 to 1200 g/m2; and a colorant deposited on a second side of the first nonwoven. A topical coating may or may not be applied to improve durability of the printed surface layer. The decorative nonwoven laminate may also amount to a single layer of the first nonwoven, which then includes a layer of colorant and a topical coating over the colorant and single nonwoven layer.

Abstract: A gas turbine engine including a core having a compressor section fluidly connected to a combustor via a primary flowpath and a turbine section connected to the combustor via the core flow path. An assembly is disposed within the gas turbine engine and includes a first part connected to a second part via a radial stack joint. The first part includes a radially inward facing surface contacting a corresponding radially outward facing surface of the second part. A fastener protrudes through the first part and the second part and is configured to maintain the relative positions of the first part and the second part. A channel is disposed on at least one of the radially inward facing surfaces and is positioned between the fastener and a circumferential edge of the first part. The channel is connected to at least one cooling air source.

Abstract: A water engine has a barrage with a differential head of water on an upstream and downstream side. The engine has a working chamber and a double acting piston member in the chamber. Valves admit water into the working chamber from the upstream side of the barrage to the two working faces of the piston member in turn to cause horizontal reciprocal movement of the piston member, and the valves also allow water to flow out of the working chamber, on the downstream side of the barrage from that side of the piston member opposite that on which water is being admitted.
