Abstract: A method for sharing a digital key associated with a vehicle by a cascaded key delegation system includes issuing, by a requestor device, a public key certificate to an initial delegator device that is part of a cloud delegation service. The public key certificate enables the initial delegator device to grant delegation rights the vehicle. The method also includes issuing, by the initial delegator, an intermediate public key certificate to a subsequent delegator that is part of the cloud delegation service. The intermediate public key certificate grants the delegation rights to the subsequent delegator.

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. A spring applies a spring force to bias the nozzle assembly toward the target zone, and moves the nozzle assembly as the location of the target zone varies. The nozzle assembly moves to a position relative to the target zone by a combination of action of the spring force and of any hydrodynamic force of the fluid, when moving through the nozzle assembly.

Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to: execute an autonomous vehicle algorithm simulating vehicle operations determine whether a notification that provides information on how a driver intervention for actuation by system feature functions has been at least one of previously presently or confirmed and cause the notification to be generated. The notification includes information for responding to a finite number of driving options determined by the driver intervention for actuation by system.
Abstract: An electric drive system for an electric vehicle is provided. The electric drive system includes a first electric drive, a second electric drive, and a switchable battery including at least two battery packs that are selectively arranged in one of a series configuration and a parallel configuration. The electric drive system also includes a first half-bridge buck converter connecting the first electric drive to a first battery back of the at least two battery packs of the switchable battery and a second half-bridge buck converter connecting the second electric drive to a second battery back of the at least two battery packs of the switchable battery. The electric drive system further includes a controller configured to control the configuration of the switchable battery, an operation of the first half-bridge buck converter, and the second half-bridge buck converter.

Abstract: Vehicles and systems and methods for providing rearview displays for vehicles are provided. An exemplary system is provided for a vehicle having a gate moveable between closed configuration and opened configurations. The system includes a camera mounted to the gate and configured to collect dynamic pixel images of an area behind the vehicle; a display screen configured to display the collected dynamic pixel images; and memory configured to include executable instructions and a processor configured to execute executable instructions that enable the processor to crop the collected dynamic pixel images to display a lower portion of the collected dynamic pixel images on the display screen when the gate is in the closed configuration, and to crop the collected dynamic pixel images to display an upper portion of the collected dynamic pixel images on the display screen when the gate is in the opened configuration.
