    • A transfer function is provided for use with computer pointing devices such as trackpads. The transfer function includes a first component having characteristics of a positional transfer function and a second component having characteristics of a velocity-based transfer function. The first (positional) component and the second (velocity-based) component of the transfer function are blended so that the transfer function exhibits purely positional behavior in response to a first range of inputs and exhibits combined positional and velocity-based behavior in response to a second range of inputs. The first range of inputs may, for example, correspond to a region in the input coordinate space that is bounded by a circle having a predetermined threshold radius.
    • 提供传递函数用于诸如轨迹笔的计算机指示设备。 传递函数包括具有位置传递函数特性的第一分量和具有基于速度的传递函数特性的第二分量。 传递函数的第一(位置)分量和第二(基于速度的)分量被混合,使得传递函数响应于第一输入范围而呈现纯粹的位置特性,并且表现出基于位置和速度的组合响应于 第二个输入范围。 输入的第一范围可以例如对应于由具有预定阈值半径的圆限定的输入坐标空间中的区域。

    • A handheld electronic device having a slidable display is provided. A display unit is slidably connected to a body unit at two (or more) sliding joints. A mechanical linkage constrains motion at all of the sliding joints to be substantially equal. In this manner, binding of the slidable display is avoided, since binding occurs as a result of unequal motion at sliding joints. In one embodiment, the linkage includes a gear-axle-gear assembly disposed in a recess in the body unit and constrained to rotate as a unit about the axis of the axle. The gears of this assembly are engaged with linear gear racks on the display unit.
    • 提供具有可滑动显示器的手持式电子设备。 显示单元在两个(或多个)滑动关节处可滑动地连接到主体单元。 机械联动限制所有滑动关节处的运动基本相等。 以这种方式,可以避免可滑动显示器的结合,因为由于在滑动关节处不相等的运动而发生结合。 在一个实施例中,联动装置包括设置在主体单元中的凹部中的齿轮轴 - 齿轮组件,并且被限制为围绕轴的轴线作为单元旋转。 该组件的齿轮与显示单元上的线性齿条架接合。
