Abstract: Disclosed is an inventory control system or parking space detector including an inductive loop technology that is either embedded in the concrete or located atop the concrete, or any other feasible method of setting an inductive loop. By monitoring the change in inductance of the magnetic field that is generated by the loop as cars of various sizes and weights enter the looped area, a determination of whether or not the inventory is controlled or the parking spaces are all full is made when the inductance value reaches a certain predetermined level. This predetermined level will be determined by calibration in the initial installation in order to determine the exact inductance values when a group of parking spaces are full.

Abstract: An apparatus for improving the aerodynamic performance of vehicles of a type having a windshield, a radiator for cooling engine coolant, a grille extending in front of the radiator for allowing air to enter the radiator and a hood extending from the top of the grille to the bottom of the windshield. A transparent airfoil extends from the front portion of the hood to the top of the windshield and from one side of the hood to the other side thereof.

Abstract: In a power and free conveyor system that includes a trolley frame having spaced pairs of load wheels supporting the trolley frame for movement in a longitudinal direction along a track and a spaced pair of guide wheels for maintaining orientation of the frame with respect to the center of the track, a system for monitoring operative condition of the trolley load and guide wheels. A pair of first sensors are respectively disposed on opposed sides of the track and responsive to sequential passage of a corresponding pair of load wheels for generating first electrical signal patterns as a function thereof. A plurality of second sensors are mounted adjacent to the track and responsive to passage of the pair of guide wheels for generating second electrical signal patterns as a function thereof. A fundamental mode asynchronous machine performs pattern recognition analysis on the first and second signal patterns to determine operative condition of the load and guide wheels in real time.
