Abstract:
A water pump includes a base, a cam, a joint, and a piston. The base includes a PTO-attachment portion, a cam-attachment portion, a first contact surface, and a second contact surface. The cam includes a central opening, a first cam contact surface, and a second cam contact surface, wherein the cam-attachment portion of the base extends into the central opening. The joint pivotally couples the cam to the cam-attachment portion of the base. In a first operating position of the cam, the first contact surface engages the first cam contact surface so that the cam is positioned at a first angle relative to the axis of PTO rotation. In a second operating position of the cam, the second contact surface engages the second cam contact surface so that the cam is positioned at a second angle, greater than the first angle, relative to the axis of PTO rotation.
Abstract:
A booster pump system, for boosting a flow of water from a water source, includes a housing having a retractable handle. The booster pump system also includes a water pump positioned within the housing. The pump has an inlet and an outlet, and is designed to raise the pressure of the flow of water by an amount in a range of 20-200 pounds per square inch. The pump is also designed to raise the flow rate of the flow of water by an amount in a range of 0.5-5 gallons per minute. The booster pump system further includes a hose reel positioned within the housing, where the hose reel supports a garden hose attached to the outlet of the pump.
Abstract:
A lawn mower system includes a lawn mower and a charging station. The lawn mower includes a rechargeable battery, an electric motor powered by the battery, and a secondary coil electrically coupled to the battery. The charging station includes a primary coil configured to induce a current in the secondary coil for charging the battery of the lawn mower.
Abstract:
A spray gun for controlling a pressurized flow of water from a water source includes a housing, a garden hose coupling, a spray head, a valve, a trigger, and a mechanism coupled to the trigger and the valve. The housing has a conduit extending through the housing, defining a flow path for the pressurized flow of water. The garden hose coupling is located on a first end of the conduit, and the pressurized flow of water enters the spray gun by way of the garden hose coupling. The spray head is connected to the housing on a second end of the conduit, and the pressurized flow of water exits the spray gun by way of the spray head. The valve includes at least one of a ball valve and a barrel valve, and is positioned along the conduit between the first and second ends of the conduit. The valve is rotatable relative to the conduit to open, partially close, and fully close the flow path. Movement of the trigger is received by the mechanism and converted to a rotation of the valve.
Abstract:
A method and system for remotely monitoring the status of a standby generator. The system includes a PLC transmitter in communication with the control unit for the generator. The PLC transmitter receives error codes from the control unit of the generator and transmits encoded error codes over the power distribution network in a home using a PLC frequency. A remote status display device can be connected to the power distribution network in the home at any convenient location. The remote status display device includes a PLC receiver that decodes the error codes. The decoded error codes are displayed on a display of the remote status display device for viewing by the home occupant at a location remote from the standby generator.
Abstract:
An idle down controller for pressure washers is responsive to the drop in pressure at the pump outlet. The controller includes a sensor disposed in the pump outlet manifold. When the fluid is being bypassed, the manifold pressure drop is communicated to an actuator. The actuator overrides the engine governor and forces the engine throttle to the idle speed. When an operator is discharging a pressurized fluid, the actuator allows the governor to operate the engine at its normal speed.
Abstract:
A method and apparatus utilize a first beam emitter and a second beam emitter coupled to the first beam emitter. The first beam emitter and the second beam emitter move in unison between a plurality of positions to indicate a plurality of distances separating the first beam emitter and the second beam emitter from endpoints of beams emitted by the first beam emitter and the second beam emitter.
Abstract:
A hose coupling system includes a housing, a valve plug, and a locking mechanism. The housing has an inlet and an outlet, and a flow path between the inlet and the outlet. The valve plug is positioned within the housing along the flow path, and is rotatable between a closed orientation and an opened orientation. The closed orientation blocks the flow path and the opened orientation unblocks the flow path. The locking mechanism is designed to releasably fasten an instrument to the housing, where the locking mechanism is adjustable between a locked position and an unlocked position. The locking mechanism and the valve plug are coupled such that adjusting the locking mechanism to the unlocked position rotates the valve plug to the closed orientation.

Abstract:
An oil-level detection system for an engine-powered product includes a dipstick designed to be received within a crankcase. The system further includes a detector attached to the dipstick, where the detector is designed to sense, from within the crankcase, a level of oil within the crankcase. The system also includes a display in communication with the detector. The display identifies information to a user related to the level of oil within the crankcase, without the user opening the crankcase.
