    • A device for use with a bed having a frame and a supporting surface includes a flexible sheet with a tether strap connected to the sheet and extending from the sheet. The flexible sheet has opposed top and bottom surfaces, with the top surface having a high friction material with a higher coefficient of friction as compared to the bottom surface, which includes a low friction material. The tether strap is configured for connection to the frame of the bed to secure the sheet in place. A system incorporating the flexible sheet may also include an absorbent pad configured to be placed on the top surface of the sheet, where the high-friction top surface resists sliding of the absorbent pad, as well as one or more wedges having a base wall that the wedge rests on and a ramp surface configured to confront the sheet when the wedge is placed under the sheet. The base wall and the ramp surface may also contain high friction and low friction materials, respectively.
    • 用于具有框架和支撑表面的床的装置包括具有连接到片材并从片材延伸的系绳的柔性片材。 柔性片具有相对的顶表面和底表面,顶表面具有与包括低摩擦材料的底表面相比具有较高摩擦系数的高摩擦材料。 系绳带被配置为连接到床的框架以将片固定到位。 包括柔性片的系统还可以包括被配置为放置在片材的顶表面上的吸收垫,其中高摩擦顶表面抵抗吸收垫的滑动,以及一个或多个具有基壁的楔 楔形件搁置在斜面上,斜面被配置为当楔形物放置在片材下方时面对片材。 底壁和斜面也可分别含有高摩擦和低摩擦材料。

    • An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical and cylindrical chambers as well as chambers that include at least one flat coupling surface. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass. The end surface of the head mass is shaped to limit the contact area between the head mass of the driver assembly and the cavitation chamber to which the driver is attached, the contact area being limited to a centrally located contact region. The area of contact is controlled by limiting its size and/or shaping its surface.
    • 一种声学驱动器组件,用于与各种气穴室结构中的任何一种,包括球形和圆柱形腔室以及包括至少一个平坦联接表面的腔室。 声学驱动器组件包括至少一个换能器,头部质量和尾部质量。 头部物体的端面被成形为限制驱动器组件的头部质量与驱动器附接到的空化室之间的接触面积,接触面积被限制在位于中心的接触区域。 通过限制其尺寸和/或使其表面成形来控制接触区域。
