    • A system for monitoring operator alertness. The system includes a sensor for detecting a head position property of a head of an operator and a controller in operative communication with the sensor. The controller is configured to collect a first plurality of time points of the head position property of the head of the operator, determine a baseline of the head position property of the head of the operator based on the first plurality of time points, collect a second plurality of time points of the head position property of the head of the operator, determine an operating condition of the head position property of the head of the operator based on the second plurality of time points, and evaluate the alertness of the operator based on a comparison of the operating condition to the baseline to identify a period of head stillness.

    • A method of dynamically changing stitch density of a quilting pattern during sewing is provided. Embodiments of the invention include dynamically changing stitch density along an axis of a sewing pattern based on identifying sewing pattern elements, which may include line segments and arc segments. Each of the line segments and/or arc segments is assigned a dynamically adjusted stitch density based on analysis of each pattern element and/or adjacent element. An adjusted stitch density is assigned to portions of pattern elements that satisfy a threshold measurement for sewing with an adjusted stitch density. In embodiments, a standard stitch density, intermediate stitch density, or an altered stitch density is automatically assigned to each portion of a sewing pattern based on an analysis of threshold length of an element, a threshold angle of a portion of the element with respect to the axis, and/or the stitch density assigned to an adjacent element.
    • 提供了一种在缝制期间动态地改变绗缝图案的针迹密度的方法。 本发明的实施例包括基于识别可能包括线段和弧段的缝合图案元素沿着缝合图案的轴线动态地改变线迹密度。 基于每个图案元素和/或相邻元素的分析,为每个线段和/或弧段分配动态调整的针迹密度。 调整针迹密度被分配给满足用调整针迹密度进行缝制的阈值测量的图案元件的部分。 在实施例中,基于对元件的阈值长度的分析,元件的一部分的阈值角相对于缝合图案的阈值长度的分析,自动将标准针迹密度,中间线迹密度或改变的针迹密度分配给缝合图案的每个部分 轴和/或分配给相邻元件的针迹密度。
