Abstract: A trailer hitch-mounted reverse sensing device for a vehicle for indicating to the driver an object behind the vehicle comprises a housing with an extension extending from the housing. The extension is configured to be removably received within a receiver of a towing hitch. The housing includes a front face having a central portion, and first and second end portions. The first and second portions are angled such that a line transverse to either the first or second end portions is directed toward the centerline of the vehicle between the front and rear of the vehicle. First and second sensors are disposed in respective first and second end portions and directed toward the rear of the vehicle along the transverse line. A control module is disposed within the housing and operably connected to the sensors to determine the distance of the object sensed by the sensors.

Abstract: An apparatus for prevention of corrosion in metal objects uses a capacitively coupled fastener or pad attached to a metal body being protected from corrosion. The metal body and the negative terminal of a source of DC voltage (battery) are grounded. The positive terminal of the source of DC voltage is connected to electronic circuitry that imparts pulses of low voltage DC through the capacitor to the fastener. These pulses of electrical current inhibit the oxidation of the metal object by providing a source of electrons to the oxidizing chemicals in contact with the metal. The electronic circuitry includes a reverse voltage protector to prevent the application of reverse source voltage. The circuitry also includes a power conditioner to supply a constant DC voltage to a microprocessor. The microprocessor generates pulses of DC signals that are amplified by a pulse amplifier and imparted to the conductive facing of the pad. For larger objects, a first and second cable are attached to a metal object.
