    • An apparatus for maintaining a support platform and a payload mountable thereon in near neutral equilibrium relative to a base structure. The support platform is spaced from the base structure by a plurality of actuators which provide the support platform with six degrees of freedom relative to the base structure about longitudinal, lateral and vertical axes. A substantially upright strut is mountable between the base structure and support platform for supporting the weight of the support platform and payload. First and second balance assemblies counteract forces imparted on the strut when the payload is moved or pivoted longitudinally and/or laterally. The forces counteracted by the first balance assembly and the second balance assembly reduce the load imparted on the actuators by the payload.
    • 一种用于将支撑平台和有效载荷安装在其上的相对于基部结构接近中性平衡的装置。 支撑平台通过多个致动器与基部结构间隔开,所述致动器围绕纵向,横向和垂直轴线相对于基部结构提供六个自由度的支撑平台。 基本上直立的支柱可安装在基座结构和支撑平台之间,用于支撑支撑平台和有效载荷的重量。 当有效载荷被纵向和/或侧向移动或枢转时,第一和第二平衡组件抵消施加在支柱上的力。 由第一平衡组件和第二平衡组件抵消的力减少了由有效载荷赋予致动器的载荷。

    • A rod-shaped magnet is mounted on a rotating unit. The rod-shaped magnet has end surfaces which are oriented in a rotating direction and are magnetized to different magnetic poles. An angle detecting unit including magnetoresistive elements is disposed so as to be offset in a radial direction of a revolution path of the magnet from the revolution path and is configured to detect a change in angle of rotation of the rotating unit by detecting a leakage magnetic field in the vicinity of a side surface of the magnet. Two position detecting units each include magnetoresistive elements and are configured to detect a change in orientation of a magnetic field in the direction of a tangent to the revolution path when facing the rod-shaped magnet and produce a switch output.
    • 棒状磁体安装在旋转单元上。 棒状磁体具有沿旋转方向取向并被磁化到不同磁极的端面。 包括磁阻元件的角度检测单元被设置为沿着磁体从旋转路径的旋转路径的径向方向偏移,并且被配置为通过检测泄漏磁场来检测旋转单元的旋转角度的变化 在磁铁的侧面附近。 两个位置检测单元各自包括磁阻元件,并且被配置为在面向杆状磁体时检测在旋转路径的切线方向上的磁场取向的变化并产生开关输出。
