Abstract: An agricultural mowing system includes: a driving vehicle having a steerable axle and a pivotable tongue and defining a travel axis; a first mower coupled to the driving vehicle; a second mower coupled to the tongue; a tongue actuator configured to pivot the tongue; a tongue angle sensor configured to output signals corresponding to a tongue angle of the tongue; and a controller operatively coupled to the tongue actuator and the tongue angle sensor. The controller is configured to: determine a lateral overlap or underlap of the mowers exceeds a threshold value based at least partially on the tongue angle and a steering angle of the steerable axle; determine a correction angle needed for the tongue to pivot such that the lateral overlap or underlap no longer exceeds the threshold value; and output a correction signal to the tongue actuator to pivot the tongue by the correction angle.

Abstract: The invention is an improved method of making an improved carbon molecular sieve (CMS) membrane in which a precursor polymer (e.g., polyimide) is pyrolyzed at a pyrolysis temperature to form a CMS membrane that is cooled to ambient temperature (about 40° C. or 30° C. to about 20° C.). The CMS membrane is then reheated to a reheating temperature of at least 250° C. to 400° C. to form the improved CMS membrane. The CMS have a novel microstructure as determined by Raman spectroscopy. The improved CMS membranes have shown an improved combination of selectivity and permeance as well as stability for separating light hydrocarbon gas molecules such as C1 to C6 hydrocarbon gases (e.g., methane, ethane, propane, ethylene, propylene, butane, butylene).

Abstract: Aspects of the present disclosure relate to techniques for mitigating inadvertent user information collection in telemetry data. In examples, user information is used to evaluate telemetry data associated prior to transmission to a server device. If an instance of user information is identified within the telemetry data, a warning indication is generated. The warning indication may be transmitted to the server device either instead of or in combination with the telemetry data. As a result of the warning indication, the software may be modified to resolve the issue that caused the introduction of the user information into the telemetry data, thereby avoiding future instances of inadvertent data collection. In response to the warning indication, the server may be configured to reject similar telemetry data from other devices, thereby avoiding collecting such data from the other devices.
