摘要： A method of forming a balanced rotor blade assembly includes measuring a weight of a plurality of sub-components of the rotor blade assembly excluding a core. A configuration of a core of the rotor blade assembly is determined. In combination, the core and the plurality of sub-components achieve a target weight distribution and moment. The core is then fabricated and assembled with the plurality of sub-components to form a rotor blade sub-assembly.

摘要： A flywheel energy storage system incorporates various embodiments in design and processing to achieve a very high ratio of energy stored per unit cost. The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years.

摘要： Systems and methods for identifying and mitigating air-fuel imbalance faults specific to an engine cylinder are provided. In one embodiment, a method comprises indicating a cylinder imbalance by comparing time-aligned readings from exhaust gas oxygen sensors, the exhaust gas oxygen sensors positioned symmetrically opposite each other within an exhaust passage downstream of a catalyst. In this way, an air-fuel imbalance fault may be accurately detected in a non-uniform exhaust flow so that mitigating actions can be taken, resulting in reduced tailpipe emissions.

摘要： In accordance with one embodiment, a bowling ball weighing apparatus comprises a weight scale and a bowling ball support assembly. The apparatus comprises a ball support assembly and a weight scale. The ball support assembly has a cradle which holds the bowling ball and the assembly has weight supports. Whenever the scale is read, one of these weight supports is supported by the scale and another is supported apart from the scale. In a first orientation of the bowling ball with a first hemisphere of the ball closer to the weight support supported by the scale, a first scale reading is determined. Then in a second orientation with the first hemisphere of the ball farther from the weight support supported by the scale, a second scale reading is determined. Comparison of the two scale readings allows determination of the weight imbalance of the ball's two hemispheres. This weighing apparatus is able to use a single, readily available commercial scale, making it low in cost to produce, and the use of an electronic weight scale allows fast, accurate readings.

摘要： A method for reducing imbalance correction weight usage during a balancing operation of a vehicle wheel assembly. An imbalance of the vehicle wheel assembly is initially determined and utilized together with an established acceptable threshold of imbalance for the vehicle wheel assembly to compute a reduced imbalance value having a magnitude less than the determined imbalance. Using the reduced imbalance value, correction weight amounts and placement locations for application to the vehicle wheel assembly are identified. Determined differences between the identified correction weight amount using the reduced imbalance value and a convention correction weight amount are identified as imbalance correction weight savings.
