Abstract: Systems and methods for automated surveillance of a fleet of vehicles in a parking area using vehicle sensors on various fleet vehicles. In particular, the vehicles in a parking area can be observed and monitored using sensors on a subset of the vehicles. The field of view of each vehicle and overall map coverage of a parking area can be used to determine which vehicles to use for surveillance and/or which sensors on various vehicles to use for surveillance. Thus, surveillance can be optimized using fleet knowledge of vehicle locations within a facility and the scope of coverage of various vehicle sensors to determine where there is overlap in coverage. Appropriate sensors on certain vehicles can be selectively activated to maintain secure coverage without burning resources unnecessarily.

Abstract: Presented are vehicle charging systems and control logic provisioning smart vehicle charging using encrypted wireless connectivity, methods for making/using such systems, and vehicles interoperable with such systems. A method of controlling a charging operation of a vehicle includes a vehicle controller retrieving a unique ID assigned to the vehicle from a memory device. When approaching an electric vehicle charging station (EVCS), the controller responsively embeds the unique ID in a wireless message, including encrypting and inserting the unique ID into a dedicated extension frame within the wireless message. The vehicle then broadcasts the wireless message with the embedded and encrypted unique ID. An EVCS controller parses the encrypted unique ID from the wireless message and transmits the encrypted unique ID to a back-office (BO) vehicle services provider.

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.
