Abstract: A method for artificial intelligence (AI) event response includes receiving an event alert or a communication associated with an event alert from a communication device. The method includes an AI system collecting additional information about at least one of the event alert, the communication device, or a user of the communication device. The method includes the AI system categorizing the event alert into one category of multiple categories based on the collected additional information. The method includes prioritizing subsequent handling of the event alert among other event alerts based on the category.

Abstract: A control system for use with a ground maintenance vehicle such as a lawn mower. The control system may include one or more control handles movable between a neutral position and at least a first drive or reverse position. The system may further include a biasing mechanism operable to bias the control handle from the first drive position to the neutral position. The biasing mechanism may be pre-deflected when the control handle is in the neutral position, yet provide little or no biasing effect to the handle until the handle is moved towards the first drive position.

Abstract: The invention relates to an injection device for the reliable introduction of a fluid into a metallurgical vessel having a refractory lining, the device being removably insertable in the lining; comprising a refractory first body (2) and a refractory second body (3) fittingly assembled, the first body (2) being made of a refractory material less permeable to the fluid than the material of the second body (3), the first and second bodies having each a surface (4, 5) adapted to contact molten metal; and having each fluid passages (6, 7) extending from fluid feeding means (8) to a surface (4, 5) adapted to contact molten metal, the relative flow resistance of the fluid passages (7) in the second body (4) being higher than that of the fluid passages (6) in the first body (2), the fluid passages (6) in the first body (2) being constituted of slots or bores. According to the invention, the fluid passages (6) in the first body (2) are independent from the fluid passages (7) in the second body (3).

Abstract: An adjustable armrest is provided for a riding lawn mower which normally has an operator's seat positioned thereon with the seat including armrests at either side of the seat. The armrests are normally pivotally movable from an operative position to an inoperative position. In the operative position, the armrests are designed to support the arms of the operator while the operator is manipulating the control levers of the mower. An adjuster plate is selectively rotatably mounted on each of the armrest support frames with the adjuster plate being selectively rotatably mounted with respect to the armrest support frame to selectively vary the amount of downward pivotal movement of the armrest. The adjuster plate has a bolt opening formed therein to facilitate the rotatable mounting of the adjuster plate on the support frame. The bolt opening is offset in at least two directions from the center of the adjuster plate so that the edges or ends thereof are spaced at different distances from the bolt opening.
