    • A test system for measuring a rotary load comprises a stepper motor drives a gear box that is mounted at one end of a frame. A torque sensor provides a measurement signal transmission. The gear box's output shaft is connected to one of the torque sensor's stubs by means of a universal joint coupling. On the other side of the torque sensor a second universal joint coupling connects the sensor to a stainless steel shaft. A low friction flange bearing is used to provide support for the shaft. An angle encoder is disposed on the end of the shaft distal to the gear box. The gear box's output shaft, the torque sensor's cylindrical shaft hubs and associated couplings are arranged such that they are directly aligned with the shaft. The test system has been designed to take automated torque and angle readings from a shaft capable of rotary motion. The measurement arm configuration with the stepper motor directly connects the torque and angle sensors to a PC based data acquisition card for acquisition and processing of data. The system operates according to a method used to make a true torque measurement of a rotary actuated shaft or wheel in a process where a first data set is acquired with the system unloaded as the shaft or wheel is actuated through the defined travel path. The actuation force applied by the stepper motor is accurately controlled through a computer interface. Torque data is measured at each angular step as the wheel is actuated in a first direction. Torque data is then measured at each angular step as the wheel is actuated in the opposite direction. A load is then placed on the test system. With the load on the system, torque data is acquired/measured at each angular step through the defined travel path. Torque data is then measured at each angular step as the wheel is actuated in the opposite direction through the defined travel path. Ultimately, the true torque, i.e. torque less the effects of friction and the system baseline mechanical profile, is determined by adjusting measurement data to virtually eliminate these two effects.

    • A passive magnetic bearing which has an exceptionally low friction couple. Radial and axial restraint is achieved through magnetic and mechanical means. The embodiment of the passive magnetic bearing has two axially magnetized rings, which each exhibit at least one pair of north and south poles. The magnetized rings are positioned in a manner where the poles are in a repulsive magnetic interaction such that the plane of symmetry which separates the like poles lies perpendicular to the axis of the rotation of a shaft and this radially constrains the movement of the shaft. Axial rigidity is added to the system by the use of ceramic bearings and related axial retaining mechanisms on one of the ring magnets thus maintaining the magnetic bearing in an otherwise unstable axial plane.
    • 一种具有极低摩擦力的无源磁轴承。 通过磁力和机械方式实现径向和轴向约束。 无源磁轴承的实施例具有两个轴向磁化的环,每个环表现出至少一对北极和南极。 磁化环以这样的方式定位,其中磁极处于排斥磁相互作用,使得分离相同磁极的对称平面垂直于轴的旋转轴线,并且这径向地限制轴的运动。 通过在其中一个环形磁体上使用陶瓷轴承和相关的轴向保持机构将轴向刚度加到系统上,从而将磁轴承保持在另外不稳定的轴向平面。

    • A method is provided of predicting changes in market share, in the form of Preference Shares, in a market associated with proposed performance changes. The initial step is to provide a set of market research data suitable for CVA, including current market share data. The next step is to perform a CVA analysis through regression analysis in order to determine WWP parameters, so that for the market as a whole, a set of coefficients determining relative importance of each value driver to WWP, and for each market participant, a set of performance scores for each value driver, and an overall WWP value. The method continues by postulating a changed value in the performance score for one or more value drivers for a selected market participant. The postulated changed value is used to determine a predicted WWP value through relative impacts of the components associated with the WWP model. Finally, a postulated market value as a function of the calculated WWP value is calculated, so as to derive a postulated change in market share associated with postulated change.

    • An electromagnetic motor system with no counter/back electromotive force due to the ability of the system to change from one magnetic state to another magnetic state in a defined sequence. In the first state a kinetic energy component is added to the system's rotor where two permanent magnetic materials, which are affixed to the rotor, are allowed to come into an angular range such that they act in a symmetrical manner on a fixed soft ferromagnetic material. This fixed soft ferromagnetic material also acts as the core of an electromagnetic coil and when the rotor's permanent magnets are at the closest proximity to the soft ferromagnetic core a voltage is applied across the coil, resulting in the soft ferromagnetic coil being saturated in a horizontal manner where previously it was polarized in a vertical manner while under the influence of the rotor's two permanent magnets.
