Abstract: Systems and methods that provide electronic bidding on digital advertising placed on non-personal digital devices in public or semi-public settings and enable subsequent consumer actions taken on other media channels and devices to be attributed to such advertising in digital ad buying systems.

Abstract: A dual-direction actuating axle assembly is coupled to a vehicle's pair of wheels and orbital head of a steering column. The axle assembly includes a beam, a first steering knuckle coupled to the beam's first end and a second steering knuckle coupled to the beam's second end, the first and second steering knuckles coupled to the wheels, an actuating assembly coupled to the beam and having an outer cylinder, a rod slidably mounted to the outer cylinder and a piston coupled to the rod, the rod coupled to the first and second steering knuckles. The vehicle's steering column is maneuvered to actuate the piston and rod in a first direction to pivotably adjust the pair of steering knuckles in a first direction. The vehicle's steering column is maneuvered to actuate the piston and rod in a second direction to pivotably adjust the pair of steering knuckles in a second direction.
