Abstract: Apparatus are provided for automatic repositioning of fluid nozzles when operating on a workpiece with a tool. The apparatus includes a nozzle assembly configured to convey a fluid to a target zone defined on the workpiece and/or on the tool. The target zone has a location that varies over time.

Abstract: Presented are intelligent vehicle systems for automating thermal event mitigation for fully or partially enclosed vehicles, methods for making/using such systems, and vehicles equipped with such systems. A method of controlling operation of a vehicle includes a vehicle controller confirming the subject vehicle is parked and, once confirmed, responsively evaluating vehicle data indicating the vehicle is at least partially enclosed in a parking area and, thus, is in a vehicle parked in enclosed space (VPES) state. After determining the vehicle is both parked and in a VPES state, the controller detects a thermal event in a battery cell of the vehicle's battery system. Upon detection of the thermal event, the controller responsively determines path plan data with a designated route for extricating the vehicle from the parking area. The controller then commands the vehicle's autonomous driving system to execute control operations maneuvering the vehicle away from the parking area.

The controller may be a proportional-integral controller, or a proportional-integral-derivative controller. The controller may calculate a control variable based on a target number of idle agents for the cluster. The controller receives a target number of idle agents, as well as a current number of idle agents in a cluster. The controller computes the control variable based on the error between the target and current numbers of idle agents, and an integral of the error over time.
