Abstract:
A one-piece headlight adapter, and a two-piece headlight adapter system, is used to connect the existing vehicle headlight controls and power supply with a snowplow wiring harness. An adapter only connects the controls and power supply for one headlight to the wiring harness. Two adapters, one for each headlight, create an adapter system. The adapter system allows the vehicle operator to control the snowplow headlights from the inside of the vehicle. One version of an adapter is a three-component adapter that includes one connection to the vehicle headlight, one connection to the headlight controls, and one connection to the wiring harness. Another version of the adapter is a five-component adapter that includes high and low beam connections to the vehicle headlight, high and low beam connections to the headlight controls, and one connection to the wiring harness. In each version, the connections of the adapter include a connection to the common ground which ensures a fixed potential on which the snowplow headlights operate.
Abstract:
A snowplow control system is provided that uses the distance between the vehicle frame and the ground or wheel axle as an input to a feedback loop useable to provide increased control over the pressure exerted by the plow blade. The control system allows the plow to operate in various modes of operation including a manual mode, a float mode, and a down pressure mode. The control system interfaces with the vehicle operator by way of a controller that is preferably operable from within the cabin of the vehicle.
Abstract:
The present invention is a membrane switch. The membrane switch includes a switch assembly having a switch frame coupled to the switch assembly. The switch frame is sandwiched between various layers of the membrane, thus holding it in place. The lower surface of the membrane is coated with an adhesive. Once installed in an electronic device, the adhesive layer secures the membrane as well as the switch assembly in place. The adhesive layer serves to form a waterproof barrier between the membrane and the switch assembly.
Abstract:
A universal control adapter system allows any commercial or custom snowplow controller to be quickly and easily attached and detached from any commercial or custom snowplow blade. A first adapter connects the snowplow driver's controller to a first universal controller. A second adapter connects the snowplow to a second universal connector, where the second universal connector is configured to removably mate with the first universal connector. The first universal connector and second universal connector are color coded or otherwise configured to ensure proper mating. In this manner, skilled snowplow drivers can quickly and easily transfer their controllers to different vehicles rather than learning different controls for various snowplow manufacturers.
Abstract:
The present invention is a control system for a vehicle that utilizes a powered attachment such as a material spreader. Such a device requires the use of a high current drawing motor, which in turn requires the ability to control the flow of high amperage current. The high current switching circuitry is mounted on or near the electric motor to prevent the heat generated by the circuitry from posing any type of hazard. A low current control is placed within the cab of the vehicle and serves to remotely control the switching circuitry.
Abstract:
A capacitor module is utilized as part of a vehicle accessory system to accommodate the use of accessories that require high current power supplies on many different vehicles, thereby reducing the demands on the vehicle electrical systems. The capacitor module includes a plurality of ultracapacitors capable of maintaining relatively high charge levels and thereby accommodating the demands for short bursts of high current electrical power. Control circuitry is included to manage capacitor charging using lower current signals, thereby allowing for use of accessories on vehicles having lower capacity electrical systems. In one embodiment the accessories contemplated include a snow plow attached to a vehicle, with the snowplow having a hydraulic pump motor which requires high levels of electrical current for operation. Control circuitry manages charging using a relatively constant current electrical signal and discharging of the capacitors as necessary to operate the pump motor.

Abstract:
The present invention is a snowplow diagnostic and connection system for connecting a snowplow to a vehicle. The system includes an diagnostic circuit and an indicator which detects and indicates the status of various components of the snowplow and its controls. The indicator includes a specific indication of the status of each detected subsystem or each component, as well as providing a general warning if any problem is detected. The indicator has a plurality of LED's which individually represent the various subsystems or components. If a problem is detected with any of the subsystems or components, the vehicle's headlights are caused to flash, thus alerting the operator.
