摘要： A linear actuator assembly is provided, the assembly including a linear actuator, an elongated guide spaced in parallel alignment with the linear actuator and a movable carriage disposed therebetween. The carriage includes a first notch to receive a rod of the linear actuator and a second notch to receive the guide. The carriage remains in direct and continuous contact with the linear actuator and the guide at the first notch and second notch, respectively, when the carriage moves linearly back and forth along a travel axis.

摘要： Methods for performing a scheme that results in a refined measurement pattern within an optical grid are provided. Physically adjusting spacing of elements within an optical grid to achieve enhanced resolution is historically unfeasible, as reduction of the spacing causes light sensors of the optical grid to pick up false signals when reading light beams. Technology introduced by the present invention generates a virtual reduced spacing of the elements within the optical grid by using two signals that are slightly different. These slightly different signals can accomplish, at least, quarter-grid spacing resolution within the optical grid. Additionally, the enhanced resolution derived from the virtual reduced spacing is employed to govern movement of a motor. The motor movement is in response to one or more changes of direction such that the motor is operating in its linear range. Advantageously, the virtual reduced spacing allows for substantial movement in a non-linear phase, while only limited movement in a linear phase is necessary to locate accurately a target within the optical grid.
摘要翻译：提供了用于执行在光栅内导致精细测量图案的方案的方法。光学网格中的元件的物理调节间距在实现增强的分辨率方面历史上是不可行的，因为间隔的减小导致光栅的光传感器在读取光束时拾取假信号。本发明引入的技术通过使用略微不同的两个信号来产生光栅内的元件的虚拟缩小间隔。这些稍微不同的信号可以至少在光栅内实现四分之一格栅间隔分辨率。另外，采用从虚拟缩小间隔导出的增强分辨率来控制电动机的运动。马达运动是响应于一个或多个方向的改变使得马达运行在其线性范围内。有利地，虚拟缩小间隔允许在非线性相位中的实质移动，而仅需要在线性相位中的有限移动来精确地定位光栅内的目标。
