Abstract: A crop prediction system performs various machine learning operations to predict crop production and to identify a set of farming operations that, if performed, optimize crop production. The crop prediction system uses crop prediction models trained using various machine learning operations based on geographic and agronomic information. Responsive to receiving a request from a grower, the crop prediction system can access information representation of a portion of land corresponding to the request, such as the location of the land and corresponding weather conditions and soil composition. The crop prediction system applies one or more crop prediction models to the access information to predict a crop production and identify an optimized set of farming operations for the grower to perform.

Abstract: The present disclosure refers to a method for controlling the speed of a reciprocating load motor, wherein the motor speed is a function of two input variables, namely a user defined speed set-point and a load dependent input variable. According to the disclosure, the load dependent input variable is a function of the motor current. The disclosure also refers to a variable frequency drive for controlling the speed of a reciprocating load motor, wherein the drive is programmed to perform the presently described method.

Abstract: A locking catheter system includes a locking mechanism. The locking mechanism includes a lock body having a system lumen extending through the lock body, wherein first and second catheters are received in the system lumen. A system channel extends from the system lumen, and the system channel is configured to receive one or more of the first or second catheters. A locking channel having a lock element extends from the system lumen. The locking channel is configured to receive one or more of the first or second catheters. In an unlocked configuration the first and second catheters are received in the system channel and are movable relative to the lock body. In the locked configuration at least the second catheter is received in the locking channel, the second catheter is statically coupled with the lock body, and the first catheter is movable relative to the lock body.

Abstract: An over-the-wire retrieval system having at least one expandable filter basket deployable and retrievable over a positioning guidewire that remains in place throughout the thrombectomy procedure. The filter catheter can slidably receive the positioning guidewire allowing the positioning guidewire to navigate a collapsed filter basket past a clot before the filter basket is expanded and pulled through the clot to engage or capture clot material. The filter basket can be re-collapsed and navigated past the clot over the positioning guidewire for multiple passes through the clot. The filter catheter can be paired with a flexible capture sleeve or an aspiration sheath for collection and removal of the clot material gathered by the filter basket on each pass. The flexible capture sleeve includes, in an example, a thrombus conveyor configured to transition between everted and inverted configurations.
