Abstract: A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

Abstract: A method to control a hydraulic pump of a vehicle, the pump coupled to at least a power steering system and a power braking system is provided. The method comprises measuring steering and braking information using a brake sensor and a steering sensor; and adjusting output of said hydraulic pump based on measured information from said sensors.

Abstract: An apparatus for measuring a rate of liquid flow through a spray nozzle includes a container with an opening in a top thereof adapted to receive a liquid discharge from a spray nozzle. A level sensor comprises an electrical capacitor oriented substantially vertically in the container and configured such that as liquid rises in the container, a capacitance of the capacitor changes. A processor circuit is connected to the capacitor and is operative to measure the change in capacitance of the capacitor and convert the change in capacitance into a rate of liquid flow into the container, and a display is operative to display the rate of liquid flow. The apparatus is applicable to an agriculture or industrial application whereby an operator can periodically check the flow to determine wear or plugging of a spray nozzle.

Abstract: Apparatus and systems for a novel apparatus for determining the level of granular material in a bin. The invention comprises methods and apparatus to detect when a sensor is covered by granular material. A system is described that comprises; a metallic pin, devices and circuits to measure the electrical capacitance of the pin, devices and circuits to detect changes in the capacitance, and devices and circuits to announce the change. The invention is applicable to an agriculture application whereby an operator is alerted to a near full bin in time to stop the machinery used to fill the bin before it overflows.

Abstract: A storage apparatus and system, especially for kitchens. The apparatus includes a stationary counter portion, a moveable island riser, a lift assembly, and a guide assembly including vertically mounted guide shafts that support guide bearings situated in a housing mounted to the moveable island riser. Electronic sensors protect against operation of the lift assembly when interfering objects are sensed, and then lift assembly operation is interrupted. The moveable island riser provides cabinet space or shelving and may be provided with electrical outlets for use with common kitchen appliances.

Abstract: An attachment apparatus for attaching a ground following implement, such as a power rotary broom, to a front portion of a vehicle comprises a frame pivotally attachable to the vehicle about a first pitch axis such that a front end of the frame is positioned in front of the vehicle. The front end of the frame is pivotally attachable to an implement about a second pitch axis. Castor wheels are arranged to support the frame for movement along the ground. A front mounted broom is driven at a mid-point so that no drive parts protrude from either end thereof.
