Abstract: A drape interface structure including a rigid frame defining an opening, a membrane spanning the opening of the frame, and a drive transfer element attached to the membrane and adapted to convey motion through the membrane. The membrane includes a first region of a first elastic deformability and a second region of a second elastic deformability different from the first elastic deformability.

Abstract: A drape interface structure including a frame defining an opening, a membrane spanning the opening of the frame, and a drive transfer element attached to the membrane and adapted to convey motion through the membrane. The membrane is of a material that can deform to form a plastically deformed region in the membrane in response to an initial movement of the drive transfer element relative to the frame, such that subsequent movements of the drive transfer element in the membrane have reduced resistance from the membrane.

Abstract: Embodiments described herein relate to systems and methods for carbonating a liquid at ambient temperature. The system may include a liquid source; a carbon dioxide source; and a contactor for carbonating the liquid. The contactor may include channels and a sparge for carbonating liquid flowing through the channels. The system may produce a liquid having high levels of carbonation at ambient temperature. The sparge may generate microbubbles or nanobubbles to allow for cost-effective carbonation at ambient temperatures. The bubbles may have an average diameter of 100 ?m or less. The system may carbonate liquid at a rate of 1 gram to 10 grams carbon dioxide per liter.

Abstract: A system for monitoring tillage conditions of a field may include an agricultural implement and a tillage sensor supported on the agricultural implement. The tillage sensor has a field of view directed towards a portion of the field disposed relative to the agricultural implement, with the tillage sensor being configured to generate data indicative of a tillage floor levelness associated with a tillage floor of the field disposed below a surface of the field. The system may further include a controller configured to receive the data from the tillage sensor indicative of the tillage floor levelness as the agricultural implement moves across the field and monitor the tillage floor levelness based at least in part on the data received from the tillage sensor.
