    • This invention is provides a means of playing LP records with minimal distortion. Low distortion is achieved by eliminating tracking error normally associated with pickup cartridges mounted to pivoting tone arms. This invention discloses a tone arm that constrains the motion of the stylus to straight radial path, mimicking the cutting path of the record lathe, supported on parallel rails by free rolling spherical bearings. Unlike many previous linear tracking tone arms, this invention does not rely on air pressure or servo motor mechanisms. The use of free rolling bearings or axles between parallel tracks fashioned from rails, rods or tubes, eliminates all sources of lateral friction other than pure static and rolling friction of the balls on the rails, rods or tubes. In the preferred embodiment, the fixed rods or tubes are driven synchronously, thereby eliminating static friction of the supporting rolling balls. Friction is further reduced using magnetic or buoyant support of the tone arm to reduce bearing load to that amount minimally sufficient to maintain full contact between the rolling balls and the upper and lower rods.
    • 本发明提供了以最小的失真播放LP记录的方法。 通过消除通常与安装到枢转音臂的拾取盒相关的跟踪误差来实现低失真。 本发明公开了一种音调臂,其将触针的运动限制为直径的径向路径,模拟记录车床的切割路径,通过自由滚动的球面轴承支撑在平行的轨道上。 与许多以前的线性跟踪音臂不同,本发明不依赖于空气压力或伺服电机机构。 在由轨道,杆或管形成的平行轨道之间使用自由滚动轴承或轴,除了滚珠在导轨,杆或管上的纯静态和滚动摩擦之外,消除了所有的侧向摩擦来源。 在优选实施例中,固定杆或管被同步地驱动,从而消除支撑滚珠的静摩擦。 使用音调臂的磁性或浮力支撑来进一步减少摩擦,以将轴承负载减少到足以保持滚珠和上下杆之间的完全接触的量。

    • A wearable tubing safety vest configured to harness medical treatment delivery tubing and/or communication cables. The tubing safety vest comprises a vest component having a body-encompassing component cooperable with a plurality of releasably securable flaps, and an elongate tubing harness configured to releasably receive and retain therethrough at least one of medical treatment delivery tubing and communication cables. The tubing harness may be securely engaged with the vest component or alternatively, at least one hinge component can be interposed the vest component and the tubing harness. The vest component is configured for demountably encircling a mammalian body torso, e.g, a human infant torso, juvenile torso, or an adult torso. The tubing harness may be demountably engaged with the front or with the back of the vest component. The wearble tubing safety vest may be optionally configured for demountable engagement about an animal's torso.
