    • An anamorphic imaging system is disclosed which maximizes the use of available image area to minimize display magnification and image degradation due to display magnification, reduces the amount of anamorphic squeeze or stretch during photography to lower image degradation due to anamorphosis, and in film applications, utilizes a film frame that is only three perforations in height to reduce the amount of original film needed. The frame for either film or digital applications has an aspect ratio of approximately 16:9, is contained within the total available frame area of a three-perforation frame or digital imager, and is sized to maximize image area. In preferred embodiments, the image capture area is approximately 0.900 inches wide by approximately 0.506 inches tall.
    • 公开了一种变形成像系统,其最大限度地利用可用的图像区域以最小化由显示放大率引起的显示放大和图像劣化,减少摄影过程中的变形挤压或拉伸量,以降低由于变形引起的图像劣化,并且在薄膜应用中,利用 一个只有三个穿孔高度的胶片框架,以减少所需的原始胶片的数量。 电影或数字应用的帧具有大约16:9的宽高比,包含在三孔或数字成像器的总可用帧区域内,并且其尺寸被设计成使图像面积最大化。 在优选实施例中,图像捕获区域大约为0.900英寸宽,大约0.506英寸高。

    • An apparatus and method for detecting whether platens in a mold clamp remain parallel throughout an entire molding process. The apparatus includes a frame, a first platen having a surface orthogonal to a predetermined axis, a second platen having a surface opposing the first platen, the second platen being reciprocatable along the predetermined axis, actuating cylinders for reciprocating the second platen along the predetermined axis, and positions transducers for electromagnetically detecting the positions of a plurality of points on the surface of the second platen. The method includes the steps of emitting first and second electromagnetic interrogation pulses from a controller, transmitting the first pulse to a first transducer rod fixed relative to the first platen, and transmitting the second pulse to a second transducer rod fixed relative to the first platen and parallel to the first transducer rod, generating a first return signal when the first pulse reaches a magnet disposed adjacent to the first transducer rod and fixed relative to one end of the second platen, and generating a second return signal when the second pulse reaches a magnet disposed adjacent to the second transducer and fixed relative to an opposite end of the second platen, transmitting each of the first and second return signals to the controller, measuring the time elapsed between the emission of each pulse and the arrival of the corresponding return signal at the controller, and determining, based on the times elapsed, whether the opposing surfaces of the second platen and the first platen are substantially parallel.
    • 用于检测模具夹具中的压板是否在整个模制过程中保持平行的装置和方法。 该装置包括框架,具有与预定轴线正交的表面的第一压板,具有与第一压板相对的表面的第二压板,第二压板可沿预定轴线往复运动,用于使第二压板沿着预定轴线往复运动的致动气缸 并且定位用于电磁检测第二压板的表面上的多个点的位置的换能器。 该方法包括以下步骤:从控制器发射第一和第二电磁询问脉冲,将第一脉冲发送到相对于第一压板固定的第一换能器杆,并将第二脉冲发送到相对于第一压板固定的第二换能器杆,以及 平行于第一换能器杆,当第一脉冲到达与第一换能器棒相邻设置的磁体并相对于第二压板的一端固定时产生第一返回信号,并且当第二脉冲到达磁体时产生第二返回信号 设置在第二传感器附近并相对于第二压板的相对端固定,将第一和第二返回信号中的每一个发送到控制器,测量每个脉冲的发射与相应的返回信号的到达之间的时间 控制器,并且基于经过的时间确定第二压板的相对表面 第一压板基本上平行。
