    • A personal flotation apparatus having a main body member, a primary support member, a head support member, and a foot support member, each made of flexible, buoyant, flotation material. The primary support member, head support member, and foot support member are each connected to the main body member, such that they are substantially perpendicular to the main body member and can provide stability, buoyancy and support in various floating and swimming positions. Some embodiments include multiple main body members to increase stability, buoyancy, support and comfort, and allow for heavier users.

    • A support device for protecting one or more portions of a user's hand or arm by limiting movement thereof includes a base surface for contacting a floor or other object adjacent to the device, a curved support surface extending from the base surface, and a plurality or orifices formed in the support surface. A user's fingers and thumb can be placed through the orifices to allow the palm of the hand to rest on a portion of the support surface, suspending the heel of the hand above the support device and aligning the user's wrist with the heel. The fingers may remain freely suspended within the device.

    • Apparatus and methods for providing a pre-determined axial thrust force profile for use in a rotating machine that includes a magnetically permeable rotor with first and second surfaces and a generally perpendicular shaft is disclosed. One or more bearings support the shaft and a coil induces flux in the rotor. First and second pole pieces disposed adjacent to the first and second surfaces define first and second gaps. A series magnetic circuit including the pole pieces, the gaps and the rotor carries flux generated by current flowing in the coil. Pole pieces and gaps provide substantially similar reluctance in both gaps. Magnetic saturation characteristics of a series magnetic circuit may provide a pre-determined axial force profile as a function of coil current. A first magnetic saturation characteristic may provide a maximum axial force at a first current magnitude. A second magnetic saturation characteristic may provide a lower axial force at a current greater than the first current. The saturation characteristic may be formed by configuring the geometry and dimensions of the poles. The axial force profile may be formed to reduce the net axial thrust load on the bearings.
    • 公开了一种用于提供用于旋转机器中的预定轴向推力分布的装置和方法,所述旋转机器包括具有第一和第二表面的导磁转子以及大致垂直的轴。 一个或多个轴承支撑轴并且线圈在转子中引起通量。 与第一和第二表面相邻设置的第一和第二极片限定第一和第二间隙。 包括极片,间隙和转子的串联磁路承载由在线圈中流动的电流产生的磁通。 极片和间隙在两个间隙中提供了大致相似的磁阻。 串联磁路的磁饱和特性可以作为线圈电流的函数提供预定的轴向力分布。 第一磁饱和特性可提供在第一电流幅度下的最大轴向力。 第二磁饱和特性可以在大于第一电流的电流下提供较低的轴向力。 可以通过配置极的几何形状和尺寸来形成饱和特性。 可以形成轴向力分布以减小轴承上的净轴向推力负载。
